Solar Powered Bluetooth Controlled Grass Cutting Robot

摘要

The major objective of this project is to develop and construct an Android-operable autonomous robotic lawnmower. Here, a Bluetooth module connects arduino uno to the phone. Grass-cutting machinery formerly required costly fuel to operate. In this instance, a solar panel is employed to replenish the battery, obviating the requirement for an additional power source. Solar energy is easier to adopt and more cost-effective than other energy sources. Utilizing solar panels allows us to capture the sun's energy for the production of free power. The solar panel charges the battery that provides power to the lawnmower. Everything the machine performs is controlled via an Android application. Arduino uno is the controller of the system. Through a variety of connections, arduino uno can communicate with a Bluetooth module and DC motors. The solar grass cutter's DC motor is controlled by a Arduino uno that gets data from an Android app through a Bluetooth module. In addition, an ultrasonic obstacle detector is plugged into the input; once an impediment is detected, the machine is stopped and the sensor's data is transferred to the cloud.
