Summary:The invention relates to a robot device, in particular to a swinging device of a mechanical arm for a robot. The device consists of a parallelogram frame and two power wheels which can move. Because the parallelogram is not stable, four crossing points of the frame are connected by bearings to realize possibility of changing the shape of the quadrangle. Devices (the device are not key points for the time and unnecessary details are not provided) which can provide rotation power for wheels are arranged in the power wheels. The sum of radiuses of the two power wheels is equal to the length of the short side of the parallelogram. The two power wheels are arranged at symmetric positions of the long sides on the two sides of the parallelogram frame, namely one power wheel is arranged at a central point on one side and the other power wheel is arranged at the central point on the other side; and a contact point between the two power wheels is guaranteed.
