Abstract:
The project aims at fabricating a grass cutting machine system which makes the grass
cutter motor running through solar energy. This solar power based Grass Cutting
Machine is a robotic vehicle powered by solar energy that also avoids obstacles and is
capable of cutting the grass through Android application. The system uses 12V 7AH
battery to power the machine’s motors movements as well as the grass cutter motor. A
solar panel is used to charge the battery so that there is no need of charging machine
externally. The grass cutter and machine’s motors are interfaced to NodeMCU
microcontroller that controls the working of all the motors. Arduino is interfaced to an
ultrasonic sensor for obstacle detection. We can control machine’s motors in forward,
backward, right or left 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 the object/human/animal whatever it is and it also
provides an alarm and machine stops to go forward. So, that’s how we can protect
environment from pollution
