WCR — WATER CLEANING ROBOT Designed by Sri, Age 11, and Sumyu, Age 7 United Kingdom ?? PROBLEM: Rivers across the world, including River Loddon near my home in the UK, are suffering from serious pollution. Plastic, metal, algae and dirt are destroying river ecosystems and harming wildlife and communities. Over 75 million tons of plastic currently pollutes our oceans and rivers. Since childhood I have walked the banks of River Loddon with my father. Watching the pollution made me deeply sad and motivated me to find a solution. I asked myself one question: "Will this be helpful to people?" That question inspired WCR. DESIGN: WCR was designed in three phases after careful research and planning: PHASE 1 — MAIN ROBOT: Solar powered with 50 solar panels and a 10 horsepower turbine. Buoyancy curve for water stability. 100 metre extendable rope for wide river coverage. Strong magnets and sensors to detect and collect pollution. PHASE 2 — PLASTIC REMOVER: Light sensor detects plastic. Pump and compressor collect and crush plastic waste. Shredder breaks plastic into chips. Conveyor belt separates recyclable and non-recyclable plastic. PHASE 3 — METAL REMOVER: Electromagnetic system attracts metal. Eco-friendly citrus cleaning removes contaminants responsibly. Sorted metal reduces CO2 emissions. SCRATCH SIMULATION: Two WCR robots patrol the river using distance sensors to detect and collect pollution automatically. Watch River Loddon transform from polluted dark green to clean bright blue as WCR completes its mission! FUTURE PLANS: After mastering Python and AI, I plan to build a real WCR robot to clean River Loddon and rivers worldwide within 2 years. TEAM: Sri — Research, Design and Programming Sumyu — Simulation Testing and Support My sister Sumyu supported me throughout the simulation testing phase, helping identify and improve the project.
