Problems solved by technology
However, the area covered by furniture in the home environment has become a difficult point for sweeping robots. For example, furniture such as beds and sofas have a height difference (hole) from the ground, and this height is very close to the overall height of the current sweeping machine. Under certain circumstances, the sweeper got stuck under the sofa, or was supported by a protrusion and could not move forward, which urgently needs to be improved

The invention provides a robot sweeper hole height limit detecting device and method. The robot sweeper hole height limit detecting device comprises a GPU (graphic processing unit) module, a depth camera module, a sonar detector module and an infrared sensor module. The robot sweeper hole height limit detecting method comprises the steps of height limit detection through three distance sensors andedge walking along obstacles. The robot sweeper hole height limit detecting device has the advantages of being simple in structure and reasonable in arrangement. The robot sweeper hole height limit detecting method has the advantages of being low in computation, high in efficiency, accurate in hole detection and beneficial to improving the walking efficiency and the sweeping efficiency of a robotsweeper.
Description
technical field [0001] The invention relates to the field of robot travel control, in particular to a device and method for detecting height limit of a sweeping robot opening. Background technique [0002] With the development of science and technology, artificial intelligence robots are increasingly used in various industries to replace traditional labor. When the robot is moving, it needs to avoid obstacles. Currently, the commonly used obstacle avoidance methods for robots include: detecting the distance between the robot and the obstacle, and controlling the robot to stop moving when the detected distance is less than the preset distance. Especially the sweeping robot, as a kind of intelligent robot for automatic cleaning, can reduce people's housework burden. However, the area covered by furniture in the home environment has become a difficult point for sweeping robots. For example, furniture such as beds and sofas have a height difference (hole) from the ground, and t...
