System and method for limiting robot work region

Abstract

The invention relates to a system and a method for restricting working areas of robots. The system comprises: a movable robot, which comprises a first signal emitting unit, a second signal receiving unit and a control unit for controlling movement of the robot; and a portable responder, which comprises a first signal receiver mainly used for receiving a first emission signal emitted by the robot in a restricted area which forms a guided virtual disorientation, and the portable responder emits a second emission signal after the first emission signal is received by the first signal receiver. Then, once detecting the second emission signal, the robot detector avoids the virtual disorientation, and the control unit of the robot executes an algorithm which comprises robot turning or backing procedures until the detector cannot receive the first emission signal.

Description

technical field [0001] The present invention relates to a working area of ​​a robot, in particular to a system and method for defining a working area of ​​a robot. Background technique [0002] In the prior art, various systems are used to confine a robot to a specific physical space in order to perform certain tasks. For example, maintenance of turf, floor cleaning, inspection, transportation and entertainment require robots to operate within a certain limited range to perform the work. [0003] For example, a vacuuming robot working in a room may inadvertently run from one room to another before finishing vacuuming the first room. One solution is to confine the robot to the first room and physically prevent the robot from leaving the first room by closing all the doors. But in many houses, rooms are separated by open corridors, and doors or their physical barriers are not easily placed in the robot's exit path. Likewise, a customer may want the robot to work only in par...

Problems solved by technology

However, since the robot only sends signals to one side, and the directional notch of the virtual wall generating device, the user may not necessarily face the robot transmitting or receiving signal side when placing it, causing the virtual wall to fail. In addition, when the robot is not on the virtual wall generating device When traveling in the direction of the notch, it is possible to collide with the virtual wall generating device and make it shift, and the user is required to place the virtual wall generating device in the corner.
