Fully automated grasscutter

The fully automated grass cutter is a fully automated grass cutting robotic vehicle that avoids obstacles and is capable of fully automated grass cutting without the need of any human interaction. The system uses 5V batteries to power the vehicle movement motors as well as the grass cutter motor. The grass cutter and vehicle motors are interfaced to an PIC16F877A that controls the working of all the motors. It is also interfaced to an ultrasonic sensor for object detection. The microcontroller moves the vehicle motors in forward direction in case no obstacle is detected. Once an obstacle detection, the ultrasonic sensor monitors it and the microcontroller thus turn the robotic vehicle to the right in order to avoid any damage to the object, human, animal or whatever it is. Microcontroller then turns the robotic as long as it gets clear of the object and then moves the grass cutter in forward direction again.
