Abstract: Manual grass cutting is time-consuming, labor-intensive, and can result in an uneven structure in the grass's height. Therefore, in order to avoid all of these issues, it is essential to create a system that can cut the grass without the involvement of a human. This study's robotic mower for cutting grass has a solar-powered battery. This system can be constructed for a lot less money than other ones that are presently in use. It is strong, durable, and maintenance-free. This technology avoids pollutants by charging the battery using solar energy. The robot will stop if it finds an obstacle. The fully automated solar lawn cutter is a robotic vehicle that can completely cut grass without human assistance and runs on solar power. It can also prevent contact with obstructions. The system's 6V batteries power both the motors that propel the vehicle and the lawn cutter. We also use a solar panel to power the battery in order to do away with the need for external battery charging. An 8051 family microprocessor controls the functioning of each motor and is coupled to the vehicle and lawn cutter motors. It also has an ultrasonic sensor interface for item identification. The microcontroller moves the vehicle motors ahead if no impediments are found. To safeguard the blades, the micro controller stops the grass cutter motor when the ultrasonic sensor detects an obstruction.
