Abstract
The present invention relates to a self-moving device, where the self-moving device includes at least two non-contact obstacle detection modules, respectively located on two side of a housing in a moving direction and configured to transmit detection signals and receive reflected detection signals, to detect an obstacle in the moving direction of the self-moving device; the self-moving device further includes a control module, and the control module turns on each obstacle detection module in a time-sharing manner to transmit the detection signal and turns on each obstacle detection module in the time-sharing manner to receive the reflected detection signal, to obtain detection data; and the control module determines a location of the obstacle according to the obtained detection data, a corresponding identity of the obstacle detection module that transmits the detection signal, and a corresponding identity of the obstacle detection module that receives the detection signal, to control the self-moving device to move and/or turn to avoid the obstacle, and the identities of the obstacle detection modules are related to positions of the obstacle detection modules relative to the housing…
