An industrial robot comprises a plurality of robot arms which are movable in relation to each other and support a tool holder. The tool holder comprises an output shaft journal, to which a turning disc is attached. To electrically insulate a tool applied to the tool holder and the robot, an insulating layer is arranged between the turning disc and the shaft journal.

Industrial robot

Driving unit for an industrial robot

The invention relates to an industrial robot of a so-called agile type which has a lower arm (16) with double-sided journalling in a stand (12) consisting of two separated, upright parts (12a, 12b), the arm (16) being pivotable in the space between the stand parts. A pivot shaft (24) for pivoting the upper arm of the robot via a crank and a parallel link rod from one of the stand parts (12a) and through a lead-in opening (28) in the lower arm (16). From the other stand part (12b) there extends a drive shaft (30), which is substantially coaxially opposite to the pivot shaft (24) of the crank (22) and which is connected to the lower arm (16).
