Method and Apparatus for Controlling Robot Cleaning in Corners

Strategic Insights -

A team of inventors from China has patented a method and apparatus for controlling robot cleaning in corners. The patent, filed on May 12, 2021, and published online on September 30, 2025, aims to improve the efficiency and effectiveness of cleaning robots in navigating and cleaning right-angle corners. The inventors, Luping Che, Gao Chen, Yanyu Chen, Yaqi Ma, Longtian Tan, and others from Gree Electric Appliances Inc. of Zhuhai, have developed a system that uses machine learning algorithms to detect and analyze the environment, identify right-angle corners, and adjust the cleaning path accordingly.

According to the patent, the system involves acquiring an environmental map, detecting at least one right-angle corner point, and determining a coordinate system in which the corner point is located. The system then uses a preset condition to identify the target right-angle corner point and controls the robot to clean it. The patent also describes various embodiments, including using a corner detection algorithm to process the environmental map and performing piecewise linear fitting on corner points.

The inventors' summary states, "The disclosure provides a method and an apparatus for controlling a robot, an electronic device, and a computer-readable storage medium." The patent claims describe the method in detail, covering various aspects of corner detection, coordinate system determination, and robot control.
