Solar Powered Grass Cutting Robot

Solar Powered Grass Cutting Robot – Full Description

The Solar Powered Grass Cutting Robot is an eco-friendly and automated lawn maintenance system designed to cut grass efficiently using renewable solar energy. This robot minimizes human effort, reduces electricity consumption, and promotes green technology by operating primarily on solar power.

Working Principle

The robot uses a solar panel mounted on the top surface to convert sunlight into electrical energy. This energy is used to charge an onboard battery, which powers the DC motors, cutting mechanism, and control circuitry. The robot moves autonomously across the surface while the rotating blade trims grass uniformly. Obstacle detection sensors monitor the path and help prevent collisions.
