Embodiment Construction

[0029] When the self-mobile robot is working, the driving wheel needs to be floated and adjusted according to the change of the ground to increase the obstacle-surmounting ability of the robot. Usually, the floating obstacle-surmounting mechanism is realized by the action of a tension spring. For example, the prior art provides a cantilever driving wheel mechanism, which installs the driving wheel on the chassis of the cleaning robot through the cantilever, and uses a tension spring between the cantilever and the robot chassis to deflect the driving wheel away from the robot chassis of a location. When cleaning, the self-mobile robot deflects the wheel to another position by overcoming the spring force of the tension spring by gravity. When using this mechanism, when the self-mobile robot encounters steps or obstacles, the chassis is lifted up, and the driving wheel is deflected to a position away from the robot chassis under the action of the tension spring. During this proce...

Abstract

An embodiment of the invention provides a self-moving robot and a traveling method thereof. The self-moving robot comprises a body, a driving wheel component and an obstacle surmounting component. Thedriving wheel component is rotationally arranged on the body through a first rotating shaft and comprises a driving wheel; in a process that the driving wheel moves from a first position to a secondposition relative to the body, the obstacle surmounting component applies force to the driving wheel component, and the positive pressure variation amplitude between the driving wheel and an advancingsurface is smaller than or equal to a set threshold. In the technical scheme, when the body of the self-moving robot encountering an obstacle is jacked up or travels to a pit position, the driving wheel component is subjected to the acting force applied by the obstacle surmounting component besides own gravity; under the joint action of the forces, the positive pressure variation amplitude between the driving wheel and the advancing surface is smaller than or equal to the set threshold, so that friction between the driving wheel and the advancing surface is increased, and an obstacle surmounting performance of the self-moving robot is improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a self-moving robot and a walking method thereof. Background technique [0002] With the continuous development of science and technology, household appliances are becoming more and more intelligent. Smart home appliances have brought great convenience to users' work, life and study, and self-moving robots are one of them. The self-mobile robot can automatically complete the floor cleaning work in the room by virtue of certain artificial intelligence. [0003] At present, the driving wheels of some self-mobile robots can be floated and adjusted according to changes in ground conditions to improve the robot's ability to overcome obstacles. However, the driving force that the existing floating obstacle-crossing structure can provide to the driving wheels is small, and the robot can only cross smaller obstacles, and the obstacle-crossing ability is very limi...
