Abstract
Reporters obtained the following quote from the background information supplied by the inventors:“With the development of technologies, smart home products are applied more and more extensively, suchas the application of cleaning devices like a sweeping robot. The sweeping robot usually uses a sensor suchas a Laser Distance Sensor (LDS) for automatic navigation so as to achieve cleaning and dust absorptionof the floor. The LDS is generally located at the highest position of the sweeping robot, and a height ofthe LDS determines the ability of the sweeping robot to enter a low space.
