The final prototype is a remote-controlled river-cleaning bot that floats on plastic bottles. It uses a propeller system to navigate. The bot is steered through a Bluetooth app interface. A net collects floating waste as the bot moves through polluted water. The device is designed to be cost-effective, modular, and replicable. 

Idea: To design a remote-controlled, app-connected river cleanup bot that can: Float using low-cost materials (plastic bottles) Collect surface-level waste via a mounted net system Be controlled via Bluetooth through a custom mobile application Be scalable and suitable for mass production Objectives: Construct a buoyant base using plastic bottles Mount a lightweight platform with acrylic rings Attach a functional waste-catching net Program DC motors for mobility and Bluetooth connectivity Integrate an efficient propulsion system to overcome river current Make the electronics waterproof and easy to maintain
