Autonomous Solar Grass Cutter

Yash Rajesh Yadav, Dhruv Ashish Shah, Jinisha Uday Mehta, Chaitang Priyang Shah


The project aims at fabricating a grass cutting machine system which makes the grass cutter motor run through solar energy. The \Solar Powered Grass Cutting Machine" is a robotic vehicle powered by solar energy that also avoids obstacles and is capable of automated grass cutting. The system uses 12V battery to power the vehicle movement motors as well as the grass cutter motor. A solar panel is used to charge the battery so that there is no need of charging it externally. The grass cutter and vehicle motors are interfaced topic microcontroller that controls the working of all the motors. It is also interfaced to an ultrasonic sensor for obstacle detection. The microcontroller moves the vehicle motors in forward direction in case no obstacle is detected. On obstacle detection, the ultrasonic sensor monitors it and the microcontroller thus stops the grass cuter motor to avoid any damage to or through the object/human/animal is on the way. Microcontroller then turns the vehicle as long as it gets clear of the object and then moves the grass cutter in forward direction again otherwise it changes the direction.
