A method for detecting the state of a brake, the method including adjusting the current used in a braking coil of the brake, so that a braking component of the brake moves away from a first position to a second position; collecting a first current of the braking coil when the braking component leaves the first position; determining a first electromagnetic force according to a preset relationship model based on the first current; calculating a second electromagnetic force based on the first electromagnetic force; adjusting the current in the braking coil when the braking component is in the second position, so that the braking component leaves the second position; collecting a second current of the braking coil when the braking component leaves the second position; and determining a gap from the preset relationship model based on the second electromagnetic force and the second current.
