Automatic Solar Grass Cutter with GSM

Abstract

A Solar Powered Automatic Grass Cutting and Pesticide Spreading robot project is mainly proposal for reduce the manpower and usage of electricity. The automated solar grass cutter is an automated grass cutting robotic vehicle powered by solar energy that also avoids obstacles using GSM system. Solar plate is used to provide the source to the battery charging. The system uses 12V batteries to power the vehicle movement motors as well as the grass cutter motor. The system control is done by the Arduino . Automation is achieved by using sensors and Arduino. Wheels and cutting operations are done using dc motors. It is also interfaced to an ultrasonic sensor for object detection. On obstacle detection the ultrasonic sensor monitors it and the Arduino thus stops the grass cuter motor to avoid any damage to the object/human/animal whatever it is. The Arduino moves the vehicle motors in forward direction in case no obstacle is detected. Arduino then turns the robotic as long as it gets clear of the object and then moves the grass cutter in forward direction again. This design is still in the prototype stage due to financial and time constraints.
