Abstract: The present disclosure relates to robot technology, and particularly to a method, a device, and a robot for identifying charging station. The method includes: first, obtaining scanning data produced by a radar of the robot; then, determining whether an arc-shaped object exists in a scanning range of the radar of the robot based on the scanning data; finally, in response to determining that the arc-shaped object exists in the scanning range of the robot, determining that the arc-shaped object is a charging station. Compared with the prior art, the present disclosure substitutes the arc identification for the conventional concave-convex structure identification. Since the surface of the arc is relatively smooth, the data jumps at the intersection of the cross-section will not occur, hence the accuracy of charging station identification can be greatly improved.

Abstract: The present disclosure provides a method, apparatus, and terminal device for cliff detection. The method includes: obtaining a detection distance matrix of distances between a camera of a target robot and a ground within a preset detection angle range collected by the camera; obtaining a difference matrix obtained by subtracting a theoretical distance matrix from the detection distance matrix; counting an amount of elements in the difference matrix being greater than a preset first threshold; and determining a cliff is detected if the counted amount of the elements is greater than a preset second threshold. Through the overall consideration of the distance matrix of the distances within the detection angle range, even if a certain part of the ground changes its external conditions such as the color depth and the lightness, the influences on the overall detection result is extremely limited, which makes the detection result more accurate and reliable.

Abstract: The present disclosure relates to a recharging robot system. The recharging robot system may include a signal emission device including at least one signal emission channel. The at least one signal emission channel each comprises an opening. A distance between two central axes of any two adjacent signal emission channels is gradually increased along a direction facing away the signal emitters. As such, an overlapping area of signal ranges of the at least two signal emitters may be reduced, and the robot may accurately determine which signal range that the robot is within, so as to accurately align with the recharging dock.
