Abstract: An autonomous robot is designed for docking in a docking station. The autonomous robot is configured such that it will locate the docking station and dock therein, before its battery power is exhausted. The docking is such that the autonomous robot is automatically charged, such that its batteries will be fully powered for the subsequent operation.

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).
