摘要： The cleaning robot includes a robot body provided with an inner cavity, a travelling mechanism mounted at the bottom of the robot body to drive the robot body to move, a cleaning component detachably connected to the robot body and configured to clean a surface through which the robot body passes, and a laser radar mounted in the inner cavity. A light transmissive window is formed in a side wall of the inner cavity of robot body. The laser radar comprises a ranging component rotatable relative to the robot body. The ranging component emits and receives laser signals via the light transmissive window within a preset scanning angle, wherein the ranging component emits a detection signal through the light transmissive window, the detection signal is reflected upon encountering an obstacle to form a reflected signal, and the reflected signal is returned to the ranging component through the light transmissive window.

摘要： A cleaning method of a cleaning robot, a chip, and a cleaning robot. The cleaning method of the cleaning robot includes: moving forward and along a first lateral direction to form a first cleaning path; moving backward to form a second cleaning path; moving forward and along a second lateral direction to form a third cleaning path, where the second lateral direction is opposite to the first lateral direction; and repeatedly performing the first cleaning path, the second cleaning path, and the third cleaning path in turn. The cleaning method of the cleaning robot improves the cleaning effect by repeatedly performing a three-segment series of paths.
