Sweeping robot and obstacle avoidance method and device of sweeping robot

Abstract

The invention provides a sweeping robot and an obstacle avoidance method and device of the sweeping robot. The sweeping robot includes a control module and a distance detection module; the distance detection module is arranged on a region near a front edge, on the top of a panel of the sweeping robot; the control module is arranged in the sweeping robot; the control module and the distance detection module are electrically connected; the distance detection module is used for detecting a distance detection signal between the panel of the sweeping robot and a bottom surface of an object, and sending the distance detection signal to the control module; and the control module receives the distance detection signal of the distance detection module, and controls the sweeping robot to slowly runor return to a start point according to the distance detection signal. The sweeping robot and an obstacle avoidance method and device of the sweeping robot can prevent the sweeping robot from being clamped on the bottom surface of the object.

Description

technical field [0001] The invention relates to the technical field of intelligent equipment, in particular to a sweeping robot and an obstacle avoidance method and device for the sweeping robot. Background technique [0002] With the advent of the intelligent age, the emergence of various smart devices has brought great convenience to people. As an intelligent robot for automatic cleaning, the sweeping robot 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 of about 10cm from the ground, and this height is very close to the overall height of current sweepers. In addition, existing sweepers The panel of the sweeper generally protrudes in the middle, which leads to the phenomenon that the sweeper gets stuck under the sofa in some cases.

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 of about 10cm from the ground, and this height is very close to the overall height of current sweepers. In addition, existing sweepers The panel of the sweeper generally protrudes in the middle, which leads to the phenomenon that the sweeper gets stuck under the sofa in some cases.

[0003] In the prior art, the method of increasing the front edge of the sweeping robot is generally used to solve the problem of robot jamming, but this method has two shortcomings: on the one hand, the heightening of the front edge will make the sweeping robot visually abrupt and affect the appearance; On the one hand, the bottom surface of many furniture adopts a curved gradient design, and its height gradually decreases from the outside to the inside, causing the sweeping robot to be directly stuck under the furniture when it moves fast
