A multi-axial industrial robot having a compact modular design for the drive system, which can be varied in numerous ways. The robot consists of a column or stand (1), with a rocker arm (7) swingably supported thereon and an outrigger (9) swingably supported on the rocker arm. The modular construction system is achieved by locating in the rocker arm (7) the oscillatory drive (26) for the outrigger (9), as well as the oscillatory drive (16) for the arm itself. Preferably, in the rocker arm are housed the complete drives (16, 26) with only the off-drive members (21, 31) protruding outwardly. Off-drive members (21, 31) are centered and connected non-rotatably with the stand (1) and the outrigger (9). As a result, the rocker arm (7) rotates about the fixed off-drive member (21) with respect to the housing. Drives (16, 26) consist each of a motor (11, 13) and a two-step timing-belt drive (17, 20 and 27, 30), whose second step can be a gear transmission.
Industrial robot for various purposes comprising a stand, a rocker arm oscillatingly supported thereon, an outrigger oscillatingly supported on the rocker arm, and a firstr and second drive for oscillating said arm and outrigger, respectively, whereby a drivemotor of said second drive for oscillating the outrigger is located on the rocker arm, and the rocker arm is at least approximately balanced statically with respect to an oscillation axis by the weight of the outrigger wherein the improvement comprises the drive motor for the first drive being arranged on the rocker arm and a first and second off-drive member of the first and second drives being supported rotatably about said oscillation axis on the rocker arm and connected non-rotatably to the stand, said first and second drives being completely encased in a housing defining said rocker arm and only said off-drive members being directed outwardly through said housing and along the axis of rotation of the off drives and said first and second off-drive members being wheel flanges with a centering means for being screwed to the stand and outrigger, respectively.
