Definitions
- the invention relates to 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 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.
- the invention furthermore relates to a method for controlling a self moving robot.
- Such a robot which is known from US-Al -2006/0273749 can be used for cleaning areas for example by means of vacuum cleaning.
- 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.
- the robot when the charging level of the energy storage is lower than a predetermined reference level, the robot must return to the base station to recharge the energy storage. Another reason for returning to the base station might be to empty a dust container or to refill a water container.
- the base station comprises a signal emitting module which signal is being detected by a sensor of the robot.
- the robot is moved back under the control of the processor to the base station.
- the absolute position of the robot with respect to the base station Due to the signal emitted by the signal emitting module of the base station, the direction to which the robot should be moved is known. After recharging the energy storage, the robot should resume the vacuum cleaning or other operation it was performing before being interrupted.
- 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 an interrupt location where the movement of the robot is interrupted to return to the base station, means for returning the robot from the base station to the interrupt location, which means use said marking.
- marking the interrupt location the robot can easily be moved back to the interrupt location without the necessity of knowing the absolute position of the interrupt location with respect to the base station. Only the relative position of the interrupt location with respect to the robot needs to be known.
- An embodiment of the system according to the invention is characterized in that the means for marking the interrupt location comprise at least one beacon which is placed by the robot on at least the interrupt location and remains on the interrupt location at least until the robot is returned from the base station to the interrupt location.
- Such a beacon can easily be placed by a robot.
- the beacon can be physical, e.g. an object or rather semi-permanent physical change placed on the interrupt location, for example a change in temperature or colour.
- the beacon enables the robot to resume the exact position and orientation as before the moment that the operation was interrupted. In this manner the robot can resume its randomly movements as if no interruption had occurred.
- the beacon comprises a signal emitting module, which signal can be sensed by the sensor of the robot.
- the signal as emitted by the signal emitted module can be sensed by the robot by the same sensor by means of which the signal of the base station is being sensed.
- the signals differ so that the robot can recognized wether the signal is emitted by the base station or by the beacon. It is also possible that a signal emitted by the module on the beacon is sensed by another sensor of the robot.
- Yet another embodiment of the system according to the invention is characterized in that the robot comprises several beacons to be placed on a path between the interrupt location and the base station.
- a further embodiment of the system according to the invention is characterized in that the means for marking the interrupt location comprise a memory for memorizing the movements of the robot from the interrupt location to the base station, and that the means for returning the robot from the base station to the interrupt location use said memory.
- Figs. 1-5 are top views of five different embodiments of the system according to the invention. DETAILED DESCRIPTION OF THE EMBODIMENTS
- Fig. 1 shows a room 1 in which a base station 2 and a robot 3 are positioned.
- the robot is moved through the room 1, whereby the robot follows path Pl . Every time the robot reaches a wall 4 of the room 1, the direction of the linear path Pl is being changed.
- an interrupt position 5 of the robot 3 shown in fig. 1 the movement of the robot 3 is being interrupted, for example for a short break. After the break the movement of the robot 3 is being continued along path P4 extending in the same direction as the path Pl.
- Fig. 2 shows a second embodiment of 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.
- 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 Pl . The path Pl is the path along which the robot 3 was moving before the movement was interrupted.
- Fig. 3 shows a third embodiment of the system according to the invention whereby the robot 3 is first being moved along path Pl until the movement is being interrupted.
- 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.
- the beacon 7 has a certain orientation which enables the robot 3 to remember the direction of movement before the interruption.
- Fig. 4 shows a fourth embodiment of the system according to the invention which system is similar to the system as shown in fig. 3.
- Fig. 5 shows a fifth embodiment of the system according to the invention, whereby at the interrupt position 5 the base station 2 is being detected by the robot 3. While moving back to the base station 2 along path P2 the movements of the robot 3 are being memorized. When returning from the base station 2 to the interrupt position 5 the same movements but reverse are being made by the robot 3 to move the robot 3 back along a path P4 which is identical to the path P2. Also by this embodiment the robot 5 continues its movement along path P5 after the interruption.
- the signal emitting module of the base station might be a module emitting signals itself or a module emitting or reflecting signals received from the robot.
- 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.
