ABSTRACT:
A concentric joint mechanism includes a frame, a flexible spherical body, a first friction wheel, a first power device, and a fixing device. The flexible spherical body is disposed inside the frame. The first friction wheel is disposed inside the frame and abuts against the flexible spherical body for driving the flexible spherical body to rotate in a first direction. The first power device is connected to the first friction wheel for providing power to the first friction wheel. The fixing device is connected to the frame and abuts against the flexible spherical body for fixing the flexible spherical body inside the frame together with the first friction wheel.
