Solar Based Automatic Grass Cutter

This is based on survey of identification of classification of solar powered grass cutter. The solar grass cutter is a fully automated grass cutting robotic vehicle powered by solar energy that also avoids obstacles and is capable of fully automated grass cutting without the need of any human efforts. The system operated on 12V battery to power the vehicle and movement of motors as well as the grass cutter motor. We are also use a solar panel to charge the battery so that there is no need to charge the battery hence there is no need of charging it externally. The grass cutter and vehicle motors are interfaced to a PIC18F4550 that controls the working of all the motors. It is also interfaced to an obstacle sensor for object detection. The micro-controller continually moves the vehicle motors in forward direction in case no obstacle is detected. On obstacle detection the obstacle sensor monitors it and the micro-controller thus stops the grass cutter to avoid any damage to the object. Micro-controller then turns the robotic movement as long as it gets clear of the object and then turns the grass cutter in forward direction again.
