How to escape from the sweeping robot

Abstract

The invention relates to a method for getting out of trouble for a sweeping robot. The sweeping robot is a columnar structure, and the two ends of the columnar structure are respectively provided with a first walking unit and a second walking unit; the method includes: detecting that the sweeping robot is trapped in the first area; obtaining the sweeping robot The characteristic position coordinates of the robot in the same coordinate system as the first area; control the sweeping robot to travel in any direction until it encounters an obstacle in the first area; control the walking unit in the sweeping robot to take turns and update the characteristic position coordinates of the sweeping robot in real time during the movement of the walking unit in turn; judge whether the sweeping robot has escaped successfully according to the updated characteristic position coordinates. In this application, by controlling the walking units of the sweeping robot to move in turn, the sweeping robot can effectively avoid obstacles, so as to prevent the sweeping robot from being unable to get out of the predicament for a long time and affect the normal path planning.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a method for getting out of trouble for a sweeping robot. Background technique [0002] With the continuous improvement of people's living standards, the application of smart home appliances is becoming more and more extensive, and has a very broad market prospect. Sweeping robot, also known as automatic cleaning machine, smart vacuum cleaner, robot vacuum cleaner, etc., is a kind of smart household appliances, relying on certain artificial intelligence, it can clean the surface of the house. General sweeping robots use brushing and vacuum methods to sweep up debris on the ground in a certain area by brushing, and then absorb this part of debris into the garbage storage box to complete the function of floor cleaning.

AI Technical Summary

Problems solved by technology

[0003] For the drum-type sweeping robot (that is, the main body shape of the sweeping robot is a columnar structure, and a two-wheel walking unit is set on the columnar structure), it is necessary to walk normally in various complex environments, but there may be problems caused by " Dilemmas formed by obstacles such as tables, chairs, walls"

Sweeping robots will inevitably enter various predicaments in a complex environment. Once in a predicament, it is difficult to get out, which seriously affects the walking path and map planning of the sweeping robot. Moreover, even if the path of escape can be found through map planning, it cannot be confirmed. Is the whole robot vacuum off the hook?
