AI Technical Summary

Technical Problem

When a robotic vacuum cleaner is on the edge of a cliff, because the cliff sensors are only installed at the front, and the rotation direction of the track mop is opposite to the direction of the robot's movement, the robot is prone to move in the direction where the sensors are not installed, increasing the risk of falling.

Method used

By detecting whether the main unit is performing a cleaning task, the working mode is determined, and the working status of the drive wheels and cleaning components is controlled, including slow decay mode, braking mode, fast decay mode and free gliding mode. Combined with the cliff sensor triggering situation, the start and stop of the drive wheels and cleaning components are controlled to reduce the risk of falling.

Benefits of technology

This effectively reduces the risk of the cleaning components dragging the robot off the ground, improving the safety and operational flexibility of the robot vacuum cleaner.

Abstract

The invention relates to an anti-falling control method and system for a sweeping robot. The anti-falling control method for the sweeping robot comprises the steps that the working mode of a host is determined by detecting whether the host executes a sweeping task or not, and a driving wheel and a cleaning part are controlled to start working based on the working mode; when it is detected that the cliff sensor is triggered, the driving wheel is controlled to stop working; if it is detected that the working stopping time of the driving wheel exceeds a preset threshold value, the cleaning piece is controlled to stop working; when it is detected that the cliff sensor is not triggered, the driving wheel is controlled to recover working; and if it is detected that the working recovery time of the driving wheel exceeds the preset threshold value, the cleaning piece is controlled to start working. According to the scheme, the risk that the robot is dragged by the cleaning piece to fall can be reduced.
