Design of Sensor Assisted Lake Water Cleaning Robot Using Internet of Things

Water is the basic natural source of each and every individual. Nowadays a lot of pollution is found in the environment due to human waste, especially plastic waste. In this research work, a novel robotic structure is designed to collect the waste materials specifically plastic wastes from the water and provides a clean water surface. For this scheme, a boat-like structure is designed with intelligent sensors and DC motors to do the waste collection operation in an intelligent manner. A solar PV oriented battery-operated boat robot is planned to collect the waste materials from the lake water, in which the structure of the robot is efficient enough to run over the lake and accumulate plastics and put them up into the container. The purpose of this portable garbage collector robot is to encourage people to learn about and keep an eye on the condition of the lakes. Small lakes, narrow rivers, land, and drains are what the trash collector was made to clean up. The robot's movement is managed by a mobile application using Internet of Things connectivity. The effectiveness of the garbage collector's control system and its capacity for collecting waste were both put to the test. Using data gathered from tests conducted in a pool, user understands that it can travel great distances and collect lightweight recyclables like food containers, drink bottles, and plastics. Within the bounds of the available network, this apparatus is controlled to float and travel down the river. This water garbage collector uses an ultrasonic sensor to monitor the waste bin's contents; therefore, it's best to make it out of a durable yet lightweight material. The proposed Internet of Things (IoT) support is achieved by using the controller called ESP32, which provides clear network assistance to the mobile garbage collecting robot to information regarding the number of wastes collected into the dustbin as well as the respective period of collection and so on. The proposed lake water cleaning method effectively helps nature preserve the dignity of the lakes while also collecting 95% of floating trash.
