Publication number: 20230363611Abstract: A self-propelled cleaning machine includes a cleaner body, a sensing module disposed at the cleaner body and a control module. The sensing module senses a distance between an object and the sensing module, and includes a transmitter tramsmitting a light signal, and first and second receivers. The first and second receivers receive the light signal respectively to form a first sensing signal and a second sensing signal. The control module controls the cleaning machine according to the two sensing signals. Center lines of a signal range of the transmitter and a view field of the first receiver form a first intersection point. Center lines of the signal range of the transmitter and a view field of the second receiver form a second intersection point. A distance between the second intersection point and the sensing module is greater than a distance between the first intersection point and the sensing module.Type: ApplicationFiled: March 31, 2023Publication date: November 16, 2023Inventors: CHI-MOU CHAO, BO-JHIH LIN, Tzu-Tse Huang
