1	34580	SS Aqua Bots	San Jose	Community Team	Shower Saver	SS Aqua bots is a team comprising of six energetic and enthusiastic boys & girls. Many of them did not know each other before this event, but they came together in a very short time and worked as a team throughout the journey of the project.	Only about 0.3% of the Water in our universe is usable. The rest is all in Ocean, ice caps or soil. So conservation of this important resource is very essential.In households, the most amount of water usage is in Showers. This is because people waste the cold water while waiting for hot water and they also take really long showers. The current solutions to conserve these types of water wastage are inconvenient, cumbersome and expensive. Our innovative and simple solutions solve these problems and conserves water at a very low cost. We also have a working model of the proposed solution that readily shows the simplicity and cost effectiveness.
2	16985	The Ardenwood Robotics Club	Fremont	Community Team	Waste Water Recycling at Airport Security	The Team consists of six Almaden Valley friends meeting 1-2 times a week to do what we enjoy doing together, Lego Robotics.  We meet in a house garage, and the team is led by a volunteer "Coach Henry".	We are proposing a method to recycle water at airport security.  The problem noticed was when passengers go through airport security, they have to dispose of water they are carrying.  To reduce water waste, we will: 1. Place blue colored bins in front of the security counter lines at the airport, next to the garbage bins 2. The bins will be labeled “WATER ONLY” and will have a white recycling sign 3. Passengers empty out water from their bottles into this bin 4. Bottom of each bin will be attached to an underground pipe 5. Pipes will take the water to an underground water filtration system at the airport. 6. The filtered water will be used throughout the airport for watering plants, toilet flushes, janitorial needs (mopping, washing, etc.) and similar purposes.
3	31167	RoboSharks	Fremont	Thornton Junior High School	EcoSink	Our team is very dynamic and enjoys spending time together. We have five boys and two girls on the team. We all go to Thornton Junior High and our ages range from 12 to 13. The RoboSharks' favorite after meeting snack is boba tea. Additionally, during lunch time when working together, we love to eat food from Chipotle and this has become a Saturday tradition. Even though all of our personalities differ, we enjoy dancing with each other to the latest songs with the latest moves (Floss, Running Man, etc.). Often, the coaches and mentors join in! Overall, through the months we have spent together, we have learned a lot about each other and we help each other out, whether out of FLL or during FLL. Now, we look forward to meeting so we can spend time together, have fun, and complete our goals.	The EcoSink is a modified kitchen sink that is designed to save water while pre-rinsing dishes before they are loaded into a dishwasher. By filtering and recirculating water, EcoSink can save up to 85% of water during pre-rinsing. Pre-rinsing dishes in a kitchen sink using running fresh water typically consumes 20-30 gallons of water for a sink full of dishes. By recycling water during pre-rinsing, EcoSink uses only about 4 gallons in comparison. That is a saving of around 10,000 gallons of water in a year.
4	32633	Lego Leprechauns	Santa Clara	Sutter Elementary School	Conserving Water 101	We are 4 friends from Sutter Elementary. We all love lego and became even better friends while working on the FLL challenge.	Fresh water is such a crucial and limited resource that we need to conserve as much as we can. We identified one source of water waste at our school and came up with a unique solution to reduce and reuse that to water our school farm.
5	24229	TECHNOLOGIC	Folsom	Community Team	Aquapod	Our team is called Technologic. This is our second year doing FLL. We continue to grow as a team and learn a lot through the robo design, project and core value activities. This year our focus has been on learning to work better together and help each other out more. Our team is made up of varied skills - some of us like to program, others like to do project, we have a team member who is pretty artistic and we also have someone who adds the comedic element. We love working together, learning and most of all having fun!	Our project is called Aquapod. It is an eco friendly device that generates clean drinkable water from two sources - water condensation from the atmosphere and collecting rainwater. The device uses renewable energy based on solar panels and has a battery backup to be charged and used during the night. Aquapod is based on the principle it is cooler under the ground and by cycling air through an underground container we can condense the water vapor and collect it for later use. A simple turbine is used to pull air into the container and it runs off of solar power. We also have a way to collect rainwater as part of our installation and a filter to purify it while storing. We will get this out to consumers through a simple hand operated pump. We plan to work with National park services to set this up in hard to reach places without clean drinking water. We have come up with a deployment plan and cost to make this easy to implement.
6	24552	Fremont ThunderBotz	Fremont	Fred E. Weibel Elementary School	EzSprayz The sprinkler that sees grass	We are a team of 6th and 7th Graders from Fremont Unified School District. We really enjoy working together and have our moments of fun filled breaks during the meetings. The most fun part during the project was to visit Serpico Landscaping, ACWD and talk to people and survey them for improving the sprinkler design.	A redesigned sprinkler head. Fits on top of a regular sprinkler. Automatically detects grass v/s sidewalk and sprays water only on the grass!
7	23841	TechFusion	Saratoga	Redwood Middle School	FusionMeter	TechFusion is a team of four fun kids who really like working with technology. Our team is creative, hardworking, dedicated to FLL, and we love to program robots and play with Legos. We like using technology to solve problems for a better world. The team gets its high energy through the fusion of each person's enthusiasm, ideas, and talents.	The FusionMeter is a low-cost add-on to an existing brass water meter to retrofit it to be a “smart” water meter. 80% of the 228 million water meters in the US are mechanical brass meters that cannot report leaks, are costly to read manually, and do not provide real-time data.Upgrading to an electronic smart meter is verycostly for water companies. Our project is a low-cost Raspberry Pi based prototype device thatclips onto an existing meter and takes a picture of the meter reading every hour and transmits the datato the cloud. The data is used by the water company for billing and to provide water usage information and alerts via the FusionApp for smartphones and tablets.
8	16191	Spartan Robotics	Sunnyvale	Sunnyvale Middle School	Mirakl Bottle	We are a team of 5 6th graders.  This is our 3rd season of FLL and we are loving it. We have all known each other since pre-school, we all go to different schools now but still like working together and have great time building robots, solving real life problems.	Mirakl Bottle - aims to solve the problem of providing cost effective and timely solution to purifying water in disaster stricken areas. Our solution is a filtration system that can be use and throw for immediate relief in disaster areas. The bottle is an improvement over the traditional layered filtration systems but uses something called a f-sand to kill 99.9% of bacteria and protozoa in the water. Our solution only costs less than five dollars and can be added to disaster relief kits also.
9	30461	Alpha Wolves	Saratoga	Community Team	CollectorPro	We are a team of three 6th graders from The Harker School. We are concerned about the environment because we enjoy visiting places with natural beauty like our National Parks. We are very interested in science and we are all members of our school’s Math Club. All our team members have a variety of interests including sports, music and programming. Most of all, we like to have fun together! We have learned that each member brings certain strengths to all aspects of our FIRST LEGO League (FLL) project and robot. This is our first year participating in FLL and our curiosity has driven us to learn a lot about robotics and the human water cycle.Please visit our website for more information about our journey: sites.google.com/site/alphawolvesfll	Seamless integration of rainwater collection with automatic irrigation systems. One of the main problems we face today is reducing the residential water usage. As half of the water used by a home is devoted to outdoor irrigation, we focus on reducing outdoor water usage so we can make a significant impact. Another important problem is excessive urban runoff which happens when rain hits an impervious surface like a roof, and rain eventually makes its way to the ocean carrying pollutants and harming wildlife. Our innovative idea is to solve both problems by collecting rain that falls on roofs, storing it and seamlessly integrating it to supply automatic irrigation systems. Our patent-pending system will allow homeowners to enjoy the benefits of rain collection without manual effort just like how the electricity produced from solar installations are now enjoyed in many homes. When rain is diverted from roofs to automatic irrigation systems, outdoor water usage can be reduced from 20-65%. If the system is widely adopted, it can reduce urban runoff by 10-20%.
10	25516	Water Those	San Jose	Community Team	Poseidons Mighty Water Dripper	"Water Those" consists of five 7th graders. We have lots of fun while working together to build/program our robots, and to find a solution for our project. We are very proud of our project solution: the Poseidon’s Mighty Water Dripper. Our device was designed to water plants in a more effective way.	An excessive amount of water is used ineffectively on farming and gardening. A solution to this problem is the deep root watering method, which waters the plant at the roots instead of at the surface, preventing water from evaporating. There are already a few deep root watering products in the marketplace, but we improved these products by making our own version. We made it economical and less complicated to set up than other deep root watering devices. The Poseidon’s Mighty Water Dripper, our device that is simply made from pen barrels and a sturdy plastic cup, effectively conserves water by using the deep root watering method. The Poseidon’s Mighty Water Dripper costs 75% less and promotes a 30% increase in growth in small plants, such as green onions.
11	15821	RoboManiacs	Sunnyvale	Community Team	SWAT	We are the Tacobots from Fremont, California. Our team is a community team and we are nine kids ages eleven and twelve ( 5 girls & 4 boys). As a team, we like to think that each one of us brings a different “flavor” to the team. Like a taco. Different flavors come together to make something great. We all have different  bright, vibrant personalities. We are a community team, we all are from different schools such as Niles Elementary, Gomes Elementary, Hopkins Junior High, Mission San Jose Elementary, Chadbourne Elementary, and Mission Valley Elementary. Also, we love tacos & robots – Tacobots.	You cannot manage what you can’t measure.Our project SWAT (Storm Water Analysis Tool) is a device to help cities make informed,  data driven decisions about how to spend dollars for managing Storm Water.  Storm Water, unlike waste water from sewers,  is untreated and unfiltered and drains to the nearest water body. SWAT would be deployed at the drain points where storm water is typically drained to the nearest water body and help gather data about potential storm pollution in the neighborhood and help cities allocate resources accordingly.
12	32431	HYDRA BOTS	San Jose	Community Team	HydroMo	We are the Hydra Bots. Currently, we have no sponsors, and are not part of any organization. However, we have been friends for a long time and all go to Joaquin Miller Middle School. All of us are in 8th grade and look forward to participating in the Global Innovation Expo for our last year with FLL.	Our product, Hydromo, detects all of the leaks and blockages in any irrigation system. It works by monitoring the flow rate of the pipes searches for any variation. Hydromo notifies the owner when a leak or blockage is detected by SMS messaging with GPS location and flow history. The Hydromo app gives an overview of the field and the "leak zones" for the owner.
13	19342	Robo Warriors	Fremont	Ardenwood Elementary School	Stop Leaks to Stop Water Waste	Our FLL team name is the Ardenwood Robotics Club. We are a team of five students - Samika (Grade 6), Tanisha (Grade 7), Karthik and Arya (Grade 5) and Ishaan (Grade 4) from different schools with three of us participating in FLL for the last two years. The Ardenwood Robotics Club is a local community hobby club with kids coming together weekly to learn Robotics and STEM concepts.	Our  FLL Hydrodynamics Project aims to conserve water supplied to homes by eliminating water waste that is a 14% of all water supplied. We identified this waste to be from pipe leaks almost exclusively in connections from street level to inside the homes. These have been ignored so far. Our project provides a solution matrix with a choice of innovative devices based on the ease of implementation and resources available.
14	27496	The Musketeers	San Francisco	Lycee Francais de San Francisco	Water The World	The Musketeer is a team of 4 great friends (2 boys and 2 girls) trying to do their share to inform about water crisis while having a lot of fun.	We created a video game to raise awareness of the water crisis in a fun way to reach as many people as possible.
15	34537	Optimi Technezei	Fremont	BASIS Independent Fremont	The Optima Aqua Tank	We are Optimi Technezei, Team 34537, and from BASIS Independent.  We are a team of 4 boys and 2 girls—all in Middle School. All of us like to play with Legos and like to program. We are also all learning Latin which is how we named our team.	For drought-sensitive states and countries, our rainwater harvesting solution, Optima Aqua Tank, lets households, businesses and other organizations collect and recycle mother nature’s rain in a cost-effective way.  Our solution diverts water from rooftops and roadside into our underground tanks situated next to the gutter system.  Water is also absorbed by pores in grass. This water is diverted into our underground storage tank. Unlike current rain water barrels that are costly and hold a small amount of water, our solution can store thousands of gallons of water. Our solution utilizes a new steel invention from South Korea, dubbed High Specific Strength Steel that is water-resistant, durable, extremely strong and affordable.  The collected rainwater can be used for non-hygienic purposes, such as toilets, watering plants, washing cars etc.
16	6225	The Potato Cats	San Francisco	Community Team	Potty Pet Saving Water a Flush at a Time	The Potato Cats is a community team that has been together for four years.  The team gets together every weekend during the LEGO Challenge period.  The Potato Cats like all parts of the season particularly playing games to boost their Core Values.  This year, the Potato Cats had a particular challenge since one of their teammates went on a trip for 6 months.  However, they kept her in the loop and she helped out on the project.	The Potty Pet is a product that you place in your toilet to save water each time you flush.  The Potato Cats designed their product to be attractive, safe for the water system and helpful for the environment since it saves water and part of the profits for the Potty Pet will go to an organization to help endangered sea life.
17	30858	Elements of Excellence	Los Altos	Community Team	Pure H2O water purification	Elements of Excellence is a new team that was formed with a common interest in Robotics. The team has members from different schools.It is not affiliated, associated or sponsored by any organization.

18	6993	Rocklin Droids	Rocklin	Rocklin Academy at Meyers Street	Recycle water with household items for landscaping	Our team 'Aguamenti' is named after Harry Potter spell to create clean water. It consists of four fifth grade girls, three of whom are from Stratford School and one is from Basis Independent. We all love robotics, which is why we joined FLL. In FLL we also learned about the core values and loved working on our project. We are a cohesive unit that cherishes the core values of FLL. We spread awareness in our community about FLL mission, its core values and our project through presentations in schools, fundraiser etc. We also won the core values award and qualified for Global Expo in the qualifying round.	Water is a very precious commodity. Typically, 30-50% of potable water is used for landscaping. So have you ever thought of recycling dirty water? We have created a model (AguaPot) that can recycle dirty water from sinks, dishwashers, washing machines, showers, and reuse the water for landscaping. The water from these household items can contain soap, dirt, salt, lead, oil, and organic matter. This model looks like contemporary flower pot and has been built using commonly available recycled house hold materials for the filtration.
19	32207	Robo Spinners	Santa Clara	Community Team	Water purification on the go	We are a group of four 4th graders who share a love for Lego and enjoy mechanical tinkering. We came together as Robospinners for the 2017 Hydro Dynamics season. During the season, we figured out that each of us had different core strengths and we could bring it all together as a team for the success of the project. Aaditya: The scientist. I never take no for an answer. Persistence pays off! Adi: The project manager. Don’t argue guys. Focus guys! Arav: The marketeer. Love to tell the world about how this all works. Stay cool! Pranav: The engineer. Make it all work and put those together. We can do it!	Water transportation and getting pure water to poor households is a huge problem in rural areas in Asia and Africa. Our project takes the innovation of waterwheel (for transporting water) already available to these communities and makes decontaminated water available to them. The impact of solving this problem is huge, it’ll result in lower disease and death from cholera and diarrhea in these communities.We solve decontamination problem by supplementing the waterwheel transport mechanism with UV disinfection in a cost effective way by using power generated in the waterwheel.
20	33421	RoboWolves	Dublin	Community Team	Fatbergs	Robowolves is an all-girl team of sixth graders  from Fallon Middle School, Dublin CA with an eighth grader. Girls have been working hard for last a few months to come together as a team and learn the engineering concepts, do project research, develop solution and have fun.	Robowolves team developed a solution to proactively detect fatbergs while they are still being formed and alert maintenance crews to the exact location of the same so the fat accumulation can be cleared before it gets out of control and requires more time, costs and resources
21	33404	Hydro Nerds	Fremont	Mission Valley Elementary School	Xylem to the Power of Filter	We the Hydro-Nerds are a team of four sixth graders from Mission Valley Elementary school in Fremont, California.  Each of us has unique interests and skills that we combine to build robots, write software and improve lives through innovative solutions. Shrey loves non-fiction, math, biology,foreign languages, spelling, and business. He plays the piano, violin, and french horn.  Project was his favorite part of FLL.  He helped in the statistics, value proposition, contact with professionals,and marketing areas. Varish is really creative in building and art. He helped improve our robot attachment and suggested the cloth for pre-filtration. He is hoping that the Xylem Filter will be a hit. Aadrij says, FLL has really been a huge part of extracurricular activities. He really enjoyed the robot game and project and it is his 3rd year of FLL.  He is good at Math, Science, programming and plays the piano. He worked on increasing the flow rate of our filter and making our project interesting. He also loves physics and chemistry. Ayush is a Math whiz and loves to program robots.  He plays in their school's basketball team, plays the guitar, and tutors refugee children from Afghanistan.	Water borne diseases affect over 3 million people per year Globally. With our solution, this problem is solvable.  Existing solutions are expensive and not environmentally friendly. We considered how plants extract water from the soil. Our idea was to use the xylem, or the center of a tree as a filter.  Our research found a paper by MIT that confirmed our concept.  We studied and improved upon a MIT filter design to be able to implement it in areas without electricity, and with the flexibility to increase filtration rate based on the size of the family / community. We designed, constructed and tested a xylem filter system and understood its benefits and limitations. Our filter system is an inexpensive with an annual cost of only $1.80, and is biodegradable and environmentally friendly. It can be used as a filter in areas without safe drinking water.  Other potential applications for xylem filteration are as a secondary filtration system for sewage treatment or to filter household greywater to raise trees.

22	30517	Piedmont Makers Purple	Piedmont	Community Team	Smart Toilet	The Piedmont Makers Team Purple is an all-girls team composed of 10 fourth and fifth graders from Piedmont.  This is the first year Piedmont participated in FIRST Lego League and they are very excited to advance.  For their project, they created a Smart Toilet that save 2 flushes per day in a typical household.	The Smart Toilet is an innovative solution to the problem of wasting water in the household. An average toilet flushes five times per day and toilets make up 31% of overall household water usage. The Smart Toilet is able to detect liquid waste or solid waste through electronic sensors and only flush when solid waste is found--saving two of the five daily flushes in an average household or two trillion gallons per year if every toilet in the US was a Smart Toilet!
23	30788	Mindstorm Minions	San Jose	Bret Harte Middle School	Eco Friendly Mobile Car Wash	We are the Mindstorm Minions. We are a team of 5 energetic and fun loving kids from Bret Harte Middle School in San Jose. We love Robotics and have been doing FLL for 4 years now. We look forward to Robotics season every year as it gives us a chance to explore new areas, go on exciting field trips and solve challenging missions while having fun together. We are all very close friends and enjoy working as a team. We love to play various sports and video games together in our free time. FLL has not only challenged us but also has made our friendship grow stronger over the years.	Our research has shown that washing cars at home is the second largest contributor to water wastage and contamination due to chemical run off.   Washing a car at home uses up to 140 gallons of water whereas a professional tunnel car wash uses only about 9-15 gallons of water.  Our team, the Mindstorm Minions have come up with an innovative solution the “Eco-Friendly Mobile Car Wash” which combines the convenience of Home Car Wash and benefits of Professional car wash where they recycle, reuse and reclaim water.  Our mobile car wash allows customers to easily schedule an appointment through an App for their car to be washed either at their home or a location nearby.  The mobile car wash will reduce water wastage by collecting all the water after each wash and filtering it through microfiltration and reusing it.  We will prevent chemical runoff by collecting and disposing contaminated water at a water treatment facility  And finally our car wash will run by solar energy.  Hence our mobile car wash is convenient and environmentally friendly.

26	4625	The 5 Seas	Palo Alto	Castilleja School	VitaClear	We are an all girls team from Castilleja School. Our mission as a school is to have “women leading and women learning”, which is something we strive to achieve within our school community and our robotics team. Our team is made up of 6th-8th graders, all of whom are either rookies or second-year FLL participants. At the beginning of the season we had no sponsors, but today we are proud to have Peloton and Resharp as our sponsors. As a team, we all believe that girls should be involved with STEM and can excel at it, and we are out to prove that the generation of today will influence tomorrow.	Our project is a low cost, efficient biosand water filter that has a patent-pending detachable vitamin chamber called the VitaClear chamber. Our filter costs a little less than $3 for materials and is easy to maintain. Other water filters cost $30, which is 10 times our cost. The VitaClear Chamber is made of 3D printer plastic, glue, and the top of a milk carton (for the threads. Our water filter is made of laser cut ¼  inch acrylic, the top of a milk carton (for the threads), cotton makeup pads, silk, activated charcoal, coffee filters, sand, horticultural sand, and gravel.
27	33479	Water Warriors	San Jose	Joaquin Miller Middle School	The Freewill Windmill	Our names are Nikhil, Raghav, Nishanth and Abhiram, and we make up the amazing and great Water Warriors!!  With our group of four kids and two supporting coaches, we are able to belittle any problem thrown at us.  At the previous FLL tournament, we have shown our hard work/teamwork via our robot design and project.	The framework of our solution includes a windmill that brings up water from a lower water source and spreads it throughout drought-struck lands like Ethiopia and South Sudan. The windmill would serve like a labor-free pulley and will bring up the water as the rope with small rubber structures slowly pushes water up. Then, the water would rest in an elevated tank residing next to the windmill. Water can be transported through the pipes, with the help of gravity, to lower tank(s) farther away and can be consumed by humans and animals. Using carbon filtration attached to the tank faucets can provide clean water without breaking a sweat.
28	31149	Tech Queens	San Jose	Community Team	Pool Meter	We are the Tech Queens, a team of three 7th graders at Bret Harte Middle School in San Jose, CA. We came together through a love for innovation and a passion for positively impacting our environment.	Our innovative project is a pool meter that detects potential leaks in swimming pools by calculating a pool's water level, measuring changes to the level, and mapping the changes to innovative factors including the weather, pool mass, and usage.
29	27029	Animatronics	San Ramon	Community Team	Flapper Stopper	Team consists of six 7th graders from Gale Ranch Middle School in San Ramon. All team members live in the same neighborhood. With 4 boys and 2 girls, the team has a good balance of analytical and abstract thinkers who are motivated by science and what it can do to improve the world. The team has been together for over a year and love the concept of “work hard play hard”	An innovative and inexpensive solution to save water with every toilet flush An assembly system (called “Flapper Stopper”) for providing optional light and full flushes in toilets having storage tanks; Pushing down the toilet flush initiates opening of the flapper valve and the flapper stopper stops the valve from opening all the way which causes to release only a small amount of water to flush the toilet. Pushing down and holding the flush for a few extra seconds flushes full capacity of the tank. Flapper Stopper uses commonly available parts like empty plastic water bottle, mold-resistant foam and a wire or zip-tie. This solution saves over 30 gallons of water per day for a typical family of 4.
30	26380	Battle Chickens	San Jose	Community Team	Project Aqua Venti	Battle Chickens are Anchal, Anvit, Ayush, Matsya, Rachel, and Ratik. We are a community based team in Cambrian Park, San Jose, CA. Ashok Mishra is the lead coach and Vinodh Dorairajan is the second coach.	Energy efficient transportation of water using a screw pump designed by Archimedes, and powered by renewable energy. The project ideally tries to make it easy to pump water up the higher elevations in third world countries in a very cost effective manner.
31	33017	Panda Power	Los Altos	Community Team	The water conservation game called Hydronation	PandaPower is comprised of four 6th grade girls attending Bullis Charter School in Los Altos, California. The team has been together for 3 years, and is mentored by parents. The girls love learning, coding, robotics, pandas, teamwork, and are excited about ways to change the world for the better. Their hobbies include singing, leatherback sea turtles, snacking and generally being goofy.	Most people are unaware that home water use is a small portion of their overall water footprint (the amount of fresh water utilized in the production or supply of the goods and services they use). Research shows that water used to make our food, our clothes and other items far exceeds the water used in daily home activities. Panda Power created a fun mobile game to educate people about their water impact, and to change their behavior to reduce their water footprint. Players pick a fun avatar. The avatar goes through daily activities such as bathing, driving and meal choices, earning points for correct answers on the water impact of his/her choices. By the end, players have been empowered through friendly competition to change their behavior and reduce their water footprint. The team plans to encourage players to share results on social media, scaling water footprint awareness and behavior change.To develop the game, Panda Power learned how to code the game in html and css, converted the product to Git Hub and ultimately to the ioS store, where it can be downloaded as an app. They conducted market testing with over 100 users and continue to make refinements.
32	33488	Krazy Argo Kids	Saratoga	Argonaut Elementary School	Save H2O	We, Meha, Niraali, and Timothy, are three fifth graders from Argonaut Elementary. As Krazy Argo Kids, we like being a little crazy, having lots of fun, and getting things done all at the same time. Things didn’t go very well at the beginning in August when we were just FLL rookies. We often talked over each other and argued a lot during the meetings. We slowly learned to work through corporation and compromising/voting, and are now learning to work faster and more efficiently together. Our team was excited to parody the song YMCA to help educate children in water conservation. While our mission is to change the world, we had to first change ourselves. We changed from not saving water actively to reduce water wastage in our everyday activities. Niraali cut her 30 minute showers to 10, Meha stopped turning the faucet at full blast, and Timothy stopped flushing the toilet when there was no brown. Now, we take every chance to save water and are paranoid when we see others waste it. We, the Krazy Argo Kids, hope that more children in the world will change just like us, and Come on and help us now Save H2O!	There is very little water in the world, and yet kids aren’t saving it. The problem that our team identified is that kids don’t know why and how to save water. We believe that we as children, will have the best understanding of how to influence other children, so we chose this problem to make a difference. Our solution is to create a song that teaches kids how and why they needed to save water. SaveH2O is a parody of the well known song YMCA with lyrics that remind children of why and how they need to save water. We made sure to make our song catchy and easy to remember so that kids can sing it in their everyday life and then save water. In fact, once we share our video, kids are singing the water conservation tips during recess at our school such as: You can brush without running water, Along with the catchy tune, we made a video http://tiny.cc/saveh2o with a lot of special effects that makes the water conservation tips easy to remember. Save H2O will hopefully get families more water conscious, and overall reduce the community’s water wastage.
33	16278	Code & Conquer	San Jose	Community Team	NoFlush	We are team Spartan Robotics, a team representing Sunnyvale Middle School in the robotics community. We are a team of four who love to tackle problems and think outside of the box. For this year’s project, we tried to develop a flushing alternative which has the potential to save massive amounts of water with minimal cost. When developing this product, we reached out to the City of Sunnyvale. They provided use with guidance and later became our sponsors. Outside of FLL, we all love to play video games, tennis and just talk to each other in general. We are all in 8th grade, meaning this is our last year of FLL, and while we are sad to leave FIRST LEGO League, we are excited to move on to FIRST Tech Challenge and FIRST Robotics Challenge in high school!	Our project this year was a clean and efficient flushing alternative. When we started the year, we had several ideas which we wanted to pursue, all of which revolved around hydroelectric power. However, we decided we wanted to create a product which could solve a large problem which not many people realize. The problem was that every time you flush a toilet, you waste a whopping 1.4 gallons of water. When we came upon this statistic, it motivated us to create a solution to this huge problem. We began a research phase, where we scoured the internet for possible ways to reduce the number of flushes which take place in a bathroom.During our research, we came upon an interesting fact; if you neutralize the toxicity of urine, you no longer have to flush. Upon finding this fact, we decided to base our entire project upon this main concept. We then developed a liquid which consistently neutralized the toxicity of urine, while being safe and family friendly. Finally, we put that liquid in a spray bottle, so when one urinates into the toilet, they can simply spray our liquid into the bowl and save 1.4 gallons of water.
34	6993	Aguamenti	Fremont	Stratford School - Milpitas	Recycle water with household items for outdoor use	Our team 'Aguamenti' is named after Harry Potter spell to create clean water. It consists of four fifth grade girls, three of whom are from Stratford School and one is from Basis Independent. We all love robotics, which is why we joined FLL. In FLL we also learned about the core values and loved working on our project. We are a cohesive unit that cherishes the core values of FLL. We spread awareness in our community about FLL mission, its core values and our project through presentations in schools, fundraiser etc. We also won the core values award and qualified for Global Expo in the qualifying round.	Water is a very precious commodity. Typically, 30-50% of potable water is used for landscaping. So have you ever thought of recycling dirty water? We have created a model (AguaPot) that can recycle dirty water from sinks, dishwashers, washing machines, showers, and reuse the water for landscaping. The water from these household items can contain soap, dirt, salt, lead, oil, and organic matter. This model looks like contemporary flower pot and has been built using commonly available recycled house hold materials for the filtration.
35	31540	X-Bots	Cupertino	Community Team	Lead Alert	X-Bots is a team of 2 boys and 2 girls from Cupertino. They are energetic, enthusiastic and super-passionate about science and technology, not to mention robotics.	You may have lead in your drinking water, and you may not even know about it! Our solution, the Lead Alert, is an automated lead detector that checks for lead in your drinking water every morning and alerts you if lead has been detected. It also helps you narrow down where the problem is. Our solution applies both physics and chemistry and utilizes technology to test water everyday for lead.
36	4619	Lego Atoms	Los Gatos	Community Team	AutoShower	The Lego Atoms are a fourth-year team of neighborhood 7th and 8th graders attending Fisher Middle School.	Across the world, people waste millions of gallons of water. The average American shower, lasting eight minutes long, uses more than 17 gallons of water (Glen Canyon Institute). Most people step away from the water to apply soap or shampoo, and those few seconds add up over time, wasting over 100 million gallons per year in the United States alone!Introducing the AutoShower 2000. The AutoShower revolutionizes the traditional shower experience by saving water without sacrificing the quality of your shower. Using an adjustable ultrasonic sensor, the AutoShower detects when you’re standing underneath it. When you step to the side, the flow of water shuts off temporarily until you step back underneath the showerhead. Even more, the AutoShower is compatible with EVERY standard-fitting showerhead on the market, as the 3D-Printed model simply screws between the showerhead and the shower arm. Installation of the battery-powered device is simple and easy for all users. We created two working, water-resistant prototypes of the AutoShower. The first prototype was to prove the concept, and included a scale model of a shower. The second prototype is a modified shut-off shower valve that can screw into a standard shower head.
37	32480	DYNAMIX HDUO	Saratoga	Stratford Middle School	Dynapump	Team Dynamix HDuo is comprised of middle schoolers and elementary schoolers from Saratoga CA. The team comprises of two brothers, one from eight grade and one from fourth grade. They have enjoyed this great opportunity to collaborate with each other before the elder brother qualifies out of FLL.	In a world where the needy have to sacrifice their health just to get enough water to drink and grow crops, there is hope. The Dynapump team, working in tandem with the Hippo Roller Organization, can provide clean water for drinking and irrigation, and improve the quality of water for all. The Dynapump has been developed by a team of middle and elementary schoolers from Saratoga, California.The Dynapump powers a pump using the spinning motion of the Hippo Roller, which pumps water from a water source into the Hippo Roller, thus avoiding the need to carry an additional vessel. The attached filter cleans the water as it is pumped into the Hippo Roller. Upon return the Dynapump can then be connected to an irrigation system to quickly irrigate areas in order to grow crops. The Dynapump is an affordable solution to three problems, which allows it to reach more people. The Dynapump makes using the Hippo Roller easier and provides a way to fill and use the water with very little additional effort. With 55,000 Hippo Rollers in service right now, the Dynapump has a potential to benefit upwards of 100,000 people in southern Africa.
38	445	Matsuyama RoboPines	Sacramento	Matsuyama Elementary School	The Hydrofind App	Mr Mullen from Matsuyama Elementary School created the FLL Matsuyama Robopines seven year ago to encourage interest in science and engineering in 4th to 6th grade students. Last year, the team was the first Matsuyama team to advance to a Championship. This year, the Robopines were the first Matsuyama team to win a Championship Core Award. One student has been on the team for 3 years. Four students have been on the team for 2 years, and five students are new team members. Half of the team are girls, and half boys. Seven of the team members are 6th graders, and the remaining members are 5th graders. The students have had an incredible journey, developing into a strong team while learning about levees.	The Robopines created Hydrofind, a unique App that helps the human water cycle by detecting levee problems. The Robopines discovered that levees aren’t just for flood control – they are used for agriculture and urban water transport, recreation and storm water drainage. The current levee inspection systems are costly and restricted by limited human resources. The Hydrofind App was designed after Chief Deputy Director Cindy Messer of the Department of Water Resources visited the Robopines, and with emailed input from Dr Cathleen Jones of JPL-NASA. The Robopines created informational Geocaches to encourage people to visit local levees to look for problems and facilitate reporting problems to the proper authorities. A rough draft of Hydrofind was made into a Scratch app and published. To determine the cost of developing a full version of the Hydrofind app, the Robopines consulted with a professional programmer to determine the expense and feasibility of developing the this app.

By acquiring this unique skill set from our members, our team gains the strengths of imagination and creativity, which aid us in poster boards and presentations. With our different areas of expertise, we, as a team, are able to collaborate smoothly for a final refined product. Although robotics is primarily about focus and work, fun plays a key role in our team’s success. For example, our team loves to create songs and play soccer during breaks in our meetings. The results of our work ethic are remarkable and have led us to qualify in three out of four seasons. Global innovation is a new experience our team is looking forward, and we hope to have a great time.	Did you know 41.6 billion gallons are wasted every year only by dialysis centers? And that’s only in the United States! Hi, we’re the Rocklin Droids. Our team’s project for the Hydrodynamics season is to improve the way dialysis centers use, transport, and dispose of reject water. Do you ever stop to think about how much water is being wasted, all that can be put to good use? Our planet is 0.3% available fresh water, and it’s being wasted everyday. We may not be able to save all the water being wasted, but we found a couple of global solutions that will definitely help us save a whole lot of our precious water.

41	33614	BuilderBots.AI	Fremont	Community Team	The Builder Barrel	The BuilderBots are made up of 6 first time FLL'ers, all in the 4th grade, from 3 different schools. The team is sponsored by the Shanti Life organization, which empowers and enables vulnerable women in India to achieve secure livelihoods and enhance their personal safety through access to sanitation as a priority. With this mission statement in mind, the BuilderBots presented their idea for a Builder Barrel prototype. Shanti Life is ready to purchase the product when it is available and in production. Additionally, the BuilderBots are Junior Ambassadors for Shanti Life to assist with their outreach efforts.   The BuilderBots are also sponsored by the Walking School Bus, a non-profit whose goal is to empower educational attainment through mutually beneficial partnerships that promote a holistic, research based approach of: Access, Nutrition and Curriculum. Through this sponsor, the team has submitted an application to their "Search for Jugaad" contest for access to engineering mentors and a $1000 grant to help build a prototype of the BuilderBarrel and test it in Africa or India. The contest is looking for inventive and scalable ideas that can enable communities to face the challenges of education in their own backyard.	In some regions of the world, the daily burden of water collection falls mainly on women and girls. These girls walk several hours each day to collect water with heavy buckets balanced on their heads. They do not have time to go to school and miss out on getting an education. Additionally, plants and animals that are fed with contaminated water then become a contaminated food source for kids who will get sick and miss additional days of school. It is estimated that 443 million school days are lost each year due to water-related diseases.  The Builder Barrel is a mash up 2 well established products being used now; the Hippo Roller and Folia Water Filter.  It is a cheap, efficient way to transport large volumes of water and all the while filtering the water in the process. The Builder Barrel combines two labor and/or time intensive tasks into one. It allows girls in particular, more time for school since they will spend less time collecting water for their household and allowing for clean water to be used for gardening, bathing and animal consumption.
42	24923	SPAARK	Cupertino	Joaquin Miller Middle School	Aqua Pods	We are six 8th grade students from various middle schools in Bay Area, and our names are Swasti, Parthiv, Arushi, Aarushi, Ruhi and Krish. Our team name, SPAARK, is a creative combination of members’ initials which reflects our motto of teamwork while respecting individuality of each member. Though we have different schools and different personalities, we all share a common desire and passion for STEM & FLL and how it can be used to enable solutions for daily problems. This is our 3rd and final year in FLL and we're excited to bring forward an innovative solution for this year's project and a robust robotic design for the missions.	Our project addresses the problem of water wastage associated with gardening and agriculture. Our innovative yet simple solution retains water while slowly releasing fertilizers. Studies by UNWater.Org, World Water Assessment Program, and other agencies have shown that the biggest water consumption and wastage in human water cycle is for plants irrigation and agriculture. Our solution, Aqua Pods, is plant based biodegradable sponges that absorb excess water and release it to plants when needed. These pods contain natural ingredients like coffee grounds, potato and bananas peels that increase soil fertility; and are placed inside our patented design for easy replacement. It is a scalable solution to meet the needs of all agricultural market segments – from domestic to nurseries to farmlands.  Our experiments show that our solution provides 3X water savings, hence savings of trillions of gallons of water every year for human water cycle. We have several paying customers and have shared our idea and product with industry experts and peers.
43	25150	Bolt Bots 3.0	Campbell	St Lucy Parish School	Hydro Dynamics	Bolt Bots 3.0 is a team of 9 children (7 girls and 2 boys) all 6th graders at St Lucy School in Campbell CA. They do not have any sponsors. The team coaches are two of the parents (moms). This is our second season in FIRST LEGO League and the children have gained so much from this whole experience.	The team identified a problem at our meetings where lots of water was being wasted due to unfinished water bottles. People didn't know who owned which bottle and ended up opening a new bottle.The team solution was the Scratch-a-bottle label...adding a scratchable label to the existing water bottle label allows for an easy way to identify your water bottle. This reduces water wastage.
45	25933	Blockheads	Oakland	Community Team	Filtered Oases	We are a team of sixth, seventh and eighth graders from Oakland, CA. We attend Bentley School and Head Royce School. Two of us did FLL last year, but the rest of us joined this year. We learned how to work together as a team, using each person's strengths to accomplish the different tasks of programming, debugging, brainstorming, building, designing, and writing.	Our project tackled the problem of how to deliver and maintain a supply of potable water for the homeless population, who are often short of clean water for drinking and hygiene. Our solution collects rain water, filters it, stores it, dispenses it, and serves as an art installation!
