A detection module, mobile robot, robot system and ranging method

Abstract

This application discloses a detection module, a mobile robot, a robot system, and a ranging method, belonging to the technical field of electrical equipment. The detection module includes a housing, a detection component, and a reflection component. The housing has a mounting cavity. The detection component includes a transmitter and a receiver, which are disposed within the mounting cavity. The reflection component includes a driving member and a reflecting part, with the driving member connected to the reflecting part. The reflecting part has a first reflecting surface and a second reflecting surface, which are disposed within the mounting cavity. The second reflecting surface reflects the signal emitted by the transmitter from the housing to the receiver to form a reference signal. The difference between the reference distance measured using the reference signal and the measured distance obtained using the measured signal can compensate for measurement errors caused by deviations in the transmitter or receiver, thereby improving the measurement accuracy of the detection module to a certain extent.
