ABSTRACT:
A drive unit on the pedestal of an industrial robot includes a gear unit having a hollow output gear shaft driven by a drive motor, and the base of the industrial robot includes a bearing on which the pedestal is rotatably mounted and whose axis of rotation is essentially coincident with the axis of rotation of the output gear shaft, and a torsionally rigid but otherwise flexible shaft coupling connects the output gear shaft to the base.
