In today's generation the major problems are pollutants, cut of power etc. Thus, to overcome with this problem, we have come with a project on "Solar Grass Cutter" where we use solar energy for operating the machine instead of using electricity.The power consumption becomes very essential for future. Solar grass cutter is a very useful device which is very simple in construction. It is fully automated grass cutting robotic vehicle powered by solar energy that also avoids obstacles. This system uses batteries to power the vehicle movement motor as well as the grass cutter motor. It uses a solar panel to charge the battery so that there is no need of charge externally.
