Development of Smart Lawn Care System: Grass Cutting and Sprinkling with Bluetooth Control

The grass cutting robot is to be operated by the android application. Esp32 Microcontroller Serial Port (COM) is connected with the phone with the help of Bluetooth module. Grass cutter power is provided by the batteries and this charge is also used to power the vehicle movement motors in the system. Furthermore, we power the battery from a solar panel, so we aren't required to charge it other than that. The direct sunlight can be used here as our free source of electricity and we can use solar panels. The battery of the lawnmower is charged through the solar panel. The smartphone application puts complete control on the machine's movement. Additionally, we had an ultrasonic sensor that was used to detect obstacles. Automated lawnmower decreases the amount of so, which means there is less human labor required.
