Area coverage with an autonomous robot
First Claim
1. A method for operating a robot comprising:
- moving the robot over a surface initially in accordance with a first scanning mode;
detecting an obstacle;
moving the robot so as to follow the obstacle in accordance with a second scanning mode; and
, returning to the first scanning mode when the robot is beyond the obstacle.

Abstract
There is therefore provided, in accordance with a preferred embodiment of the present invention, a robotic system for systematically moving about an area to be covered. The system includes at least one boundary marker (48) located along the outer edge of the area to be covered, a robot (40) with a navigation system (41) and a sensor unit (43). The navigation system (41) navigates the robot (40) in generally straight, parallel lines from an initial location and turns the robot (40) when the robot (40) encounters one of the boundary markers (48), thereby to systematically move about the area to be covered. The sensor unit (43) senses proximity to one of the at least one boundary marker (48).
