Water pollution caused by plastic waste and floating debris has become one of the major environmental problems across oceans, lakes, and rivers. Large amounts of waste entering water bodies every day affect marine life, water quality, and the overall ecosystem. Traditional cleaning methods mainly depend on manual labour and fuel-powered boats, which are expensive, time-consuming, and not environmentally friendly. To overcome these problems, this project proposes a Hybrid Solar and Hydro Powered Autonomous Ocean Cleaning Robot that can automatically collect floating waste using renewable energy sources.

The robot works using a combination of solar energy and hydro energy. A solar panel placed on the robot converts sunlight into electrical energy, while a small hydro turbine generates power from the movement of water. These two energy sources charge a rechargeable battery, allowing the robot to operate continuously for longer durations. The robot is controlled using an Arduino Uno microcontroller and includes motors, sensors, a motor driver, and a Bluetooth communication module for movement and navigation.
