AI Technical Summary

Benefits of technology

This approach enables the robot to resume operations seamlessly, ensuring complete cleaning by marking and recalling the interrupt location, thus avoiding the need for costly position tracking and ensuring efficient cleaning operations.

Problems solved by technology

However since the absolute position of the robot at the moment that the operation of the robot was interrupted is not known, it is not possible to resume the operation from the interrupt location.
To provide the robot with means for sensing, detecting and memorizing constantly the absolute position of the robot with respect to the base station to be able to move the robot back to the interrupt location, is relatively costly and complicated.

second embodiment

[0031]FIG. 2 shows the system according to the invention, whereby at the interrupt position 5 a physical property, like for example the temperature or colour 6 of the environment is being changed. At the interrupt position the robot 3 searches the base station 2 based on signals emitted by the base station 2. The robot 3 is then moved up along a path P2 to the base station 2. At the base station 2 an energy storage can be recharged, the dust container can be emptied, a water container can be refilled, et cetera. This procedure is indicated by P3. After the procedure P3 at the base station 2 has been completed, the robot 3 is returned to the interrupt position 5 along path P4, whereby the modified property 6 is sensed by the robot 3 so that the robot 3 is able to refine the interrupt location 5. At the interrupt location 5 the robot 3 is controlled to move further along path P5 extending in the same direction as the path P1. The path P1 is the path along which the robot 3 was moving ...

third embodiment

[0032]FIG. 3 shows the system according to the invention whereby the robot 3 is first being moved along path P1 until the movement is being interrupted. At the interrupt position 5 a beacon 7 is placed by the robot 3. The beacon 7 is an object which can easily be placed and recognized by the robot 3, like for example a pin, a ball, et cetera. Preferably the beacon 7 has a certain orientation which enables the robot 3 to remember the direction of movement before the interruption.

[0033]After the beacon 7 has been placed by the robot 3, the robot 3 senses a signal emitted by the base station 2 and is being moved along path P2 to the base station 2. As with the embodiment shown in FIG. 2 several procedures P3 can take place in the base station 2. After completing of the procedures P3, the robot 3 senses the beacon 7 and is moved back to the beacon 7 along path P4. The beacon is then picked up by the robot and the robot continues its movement along path P5 extending in the same direction...

fourth embodiment

[0034]FIG. 4 shows the system according to the invention which system is similar to the system as shown in FIG. 3. By the system according to FIG. 4 several beacons 7 are being placed at the interrupt position 5 and along the path P2 to the base station 2. On its way back from the base station 2 to the interrupt position 5 the robot 3 picks up all the beacons 7.

Abstract

A system provided with a base station 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 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 by means of said marking.

Description

FIELD OF THE INVENTION[0001]The invention relates to a system provided with[0002]a base station comprising a signal emitting module,[0003]a self movable robot comprising at least an energy storage, a sensor for sensing the signal emitted by signal emitting module of the base station and a processor for controlling the movement of the robot based on the sensed signal to return the robot to the base station.[0004]The invention furthermore relates to a method for controlling a self moving robot.BACKGROUND OF THE INVENTION[0005]Such a robot, which is known from US-A1-2006 / 0273749 can be used for cleaning areas for example by means of vacuum cleaning.[0006]Such kind of a robot preferably comprises a energy storage by means of which power can be supplied to several components of the robot like a vacuum cleaner, a propelling unit for moving the robot and for example a sensor for the detecting obstacles in the neighbourhood of the robot.[0007]For example when the charging level of the energ...
