Water pollution caused by floating waste is a serious environmental issue affecting rivers and oceans worldwide. Manual cleaning methods are labor-intensive, unsafe, and inefficient for large water bodies.
The River Cleaning Robot provides an automated solution by continuously collecting floating waste without human intervention. The system integrates mechanical design, sensors, and motor control to efficiently remove debris from the water surface.
Key Features :
- Automated collection of floating waste
- Reduces human effort and health risks
- Eco-friendly solution
Suitable for rivers, canals, and lakes

( The River Cleaning Robot is an automated floating robotic system designed to collect solid waste such as plastic bottles, bags, and debris from rivers, lakes, and water bodies. The robot uses a conveyor or scooping mechanism to gather floating waste and store it onboard for disposal. This project aims to reduce water pollution, protect aquatic life, and promote environmental sustainability through robotic automation. )
