The document describes a solar powered agricultural robot. It discusses how conventional energy resources are limited and non-renewable, motivating the development of solar powered robots. The robot uses a microcontroller to control motors via an RF transmitter and receiver. Sensors monitor water levels and control pumps. The robot is autonomous, using solar panels to recharge its battery without needing an external charge. It has advantages of being eco-friendly and cost effective but limitations in solar availability depending on weather. The conclusion discusses potential for robots to help improve agriculture productivity while replacing difficult, dangerous human jobs.
