Autonomous lawnmower using laser scanner

This invention describes a robotic lawnmower that uses a spinning laser to scan its surroundings. It measures how far away objects are and how strong the laser signal is when it bounces back. Based on these measurements, the lawnmower figures out what kind of surface is around it, like grass or a path, and then plans its route to cut the lawn. The claims specifically focus on using both distance and signal strength to classify surfaces and guide the mower.
