The invention relates to an industrial robot with two lower robot arms directed upwards from a fixed robot stand, the robot arms at their lower end being pivotably journalled in the stand around horizontal axes and at their upper end being pivotably interconnected by a yoke in such a way that a four-bar linkage is formed. The linkage is provided with a first driving unit. An upper robot arm is journalled around a fifth axis in a fixing member which is supported by the yoke and which is rotatably journalled around a sixth axis. The upper robot arm and its fixing member are provided with a second and a third driving unit, respectively.
