Floor sweeping robot and control system and control method thereof

Abstract

The embodiment of the invention provides a floor sweeping robot and a control system and control method used for the floor sweeping robot. The system comprises an accelerometer and a controller, wherein the accelerometer is used for detecting the acceleration of the floor sweeping robot in at least two directions in a movement plane of the floor sweeping robot; the controller is used for determining a movement mode in which the floor sweeping robot is currently located; according to the movement mode, the current expected acceleration of the floor sweeping robot in at least two directions is determined; according to the current expected acceleration of the floor sweeping robot in the at least two directions and the acceleration of the floor sweeping robot in the at least two directions detected by the accelerometer, whether or not the floor sweeping robot collides is determined; under the situation that the floor sweeping robot collides, the collision direction and/or collision strength are determined; according to the collision direction and/or collision strength, a sweeping strategy of the floor sweeping robot is determined. The floor sweeping robot and the control system and control method used for the floor sweeping robot have the advantages that the collision direction and/or collision strength of an obstacle can be accurately judged.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a sweeping robot, a control system and a control method for the sweeping robot. Background technique [0002] With the rapid development of science and technology, people's living standards continue to improve, and smart products are more and more widely accepted and applied by the public. The typical one is the sweeping robot. The sweeping robot is an intelligent cleaning device that can automatically clean dust, hair, paper scraps and other substances on the ground. With the intelligentization of sweeping robots, there are more and more sensors and measuring devices on sweeping robots, including a large number of hardware devices, such as laser ranging equipment, camera equipment, various sensors, and motion control systems and vacuum cleaner motors , It is a very large power consumption for mobile charging equipment such as sweepers. [0003] During the indoor cleaning pr...

However, this type divides the front semicircle cover into 3-9 sections, and judges the direction of the collision according to the section where the collision occurs. The defect of this kind of collision device is that the accuracy of collision position judgment is not high enough, which is limited by the number of sections divided by the front semicircl
