System as well as a method for controlling a self moving robot
First Claim
1. A system comprising:
- a base station comprising a first signal-emitting module for emitting a first signal, anda self-movable robot comprising at least an energy storage, a sensor for sensing the first signal and a processor for controlling movement of the robot, based on the sensed first signal, to return the robot to the base station,said robot;
moving randomly over a surface, without memorizing absolute positions of the robot,providing a marking at an interrupt location where the random movement of the robot is interrupted, andreturning from the base station to the interrupt location by using said marking.

Abstract
A system provided with a base station (2) comprising a signal emitting module, a self movable robot comprising at least an energy storage, a sensor for sensing this signal emitted by signal emitting module of the base station and a processor for controlling the movement of the robot by means of the sensed signal to return the robot to the base station. The robot comprises means for controlling the movement of the robot to move the robot randomly over a surface, whereby the absolute position of the robot is not memorized, means for marking the interrupt location (5) where the movement of the robot is interrupted to return to the base station and means for returning the robot from the base station to the interrupt location (5) by means of said marking.

6. A method for controlling a self-moving robot, the method comprising:
-
moving the robot randomly over a surface without memorizing absolute positions of the robot, interrupting the random movement of the robot for return to a base station, providing a marking at an interrupt location where the random movement of the robot is interrupted, sensing a signal emitted by an emitting module of the base station, moving the robot by means of the signal to the base station, returning the robot from the base station to the marked interrupt location by using the marking, resuming the random movement of the robot over the surface. - View Dependent Claims (7, 8, 9)

10. A method for controlling a self-movable robot for cleaning a surface, said method comprising:
-
moving the robot randomly over the surface without memorizing absolute positions through which said robot moves; upon the occurrence of a predetermined condition of the robot, interrupting the random movement of said robot for return to a base station; providing a marking at a location where the random movement of the robot is interrupted; sensing a signal emitted from the base station and utilizing said signal for guiding the robot to the base station; and returning the robot from the base station to the marking, where the random movement of the robot was interrupted. - View Dependent Claims (11, 12, 13, 14, 15, 16)
