Abstract: Disclosed are a rotating wheel apparatus, a driving wheel and a robot. The rotating wheel apparatus includes: a rotating assembly, a bearing and a supporting base. The rotating assembly is provided with an accommodating groove. The bearing is accommodated in the accommodating groove and connected to the rotating assembly. The supporting base is close to a notch of the accommodating groove, the supporting base is connected to the bearing, so that the rotating assembly is rotationally connected to the supporting base.

Abstract: Disclosed are a counterweight structure, a robot and a method for controlling the robot. The counterweight structure includes an electromagnetic device, a counterweight block and a reset piece. The reset piece is clamped between the electromagnetic device and the counterweight block. The electromagnetic device is magnetic after being powered on, to attract the counterweight block to move towards the electromagnetic device and compress the reset piece.
