Abstract: A building element for a modular device includes a male connector comprising M first magnets, a first ground terminal, a first detection terminal, a first power terminal, and a first signal terminal; and a female connector comprising M second magnets that are magnetically attractable to the first magnets, N second ground terminals, O second detection terminals, P second power terminals, and a second signal terminal. When the male connector of one building element is mechanically connected to the female connector of another building element, the first ground terminal, the first detection terminal, the first power terminal and the first signal terminal of the male connector of the one of two building elements respectively come into contact with one of the second ground terminals, one of the second detection terminals, one of the second power terminals, and the second signal terminal of the other one of the two building elements.

Abstract: The present disclosure provides a servo calibration method as well as an apparatus and a robot using the same. The method includes: obtaining data of a position sensor on a motor shaft of the servo; obtaining data of a position sensor on an output shaft of the servo; determining whether a clutch protection has been performed on the servo based on data of the position sensor on the motor shaft and data of the position sensor on the output shaft; and calibrating a position of the motor shaft based on the data of the position sensor on the output shaft, if the clutch protection has been performed on the servo. Through the present disclosure, the problem in the prior art that the process of the calibration is cumbersome can be solved.
