Abstract

The invention relates to a sweeping robot and a roller fault detection method thereof. The method includes: transmitting an optical signal to the roller; receiving a reflected light signal after the optical signal is reflected by the roller; The signal is used as the starting point; according to the reflected light signal that has experienced a preset duration from the starting point, the judgment of the state of the roller is made; when the state of the roller is abnormal, the control of the reflected light signal to the sweeping robot is limited, so that when the state of the roller is abnormal, limit The control of the sweeping robot by the reflected light signal, that is to say, ignores the alarm of the abnormal state of the roller, and only uses other built-in control methods of the sweeping robot to control the behavior of the sweeping robot, which can improve the working efficiency of the sweeping robot.

Description

technical field [0001] The invention relates to a sweeping robot, in particular to roller fault detection of the sweeping robot. Background technique [0002] In the traditional technology, the two sides of the sweeping robot are usually provided with driving wheels for moving in the working area. The sweeping robot can be equipped with sensors to monitor the working status. In order to meet the miniaturization design requirements of the sweeping robot, the sweeping robot can be provided with a driven roller at an appropriate position between the two driving wheels. The sensor monitors the state of the roller to reflect the working state of the sweeping robot. For example, when the sweeping robot is prevented from moving by an obstacle, the sensor can monitor the stationary state of the rollers, so that the sweeping robot will issue a warning of abnormal operation. [0003] There is following technical problem in above-mentioned traditional technology: [0004] When the ...
