Abstract: An active arm module for the robot arm of a modular industrial robot has a first housing, first and connection sides arranged at an offset, and a drive device. The first connection side is mounted rotatably relative to the first housing, and is connected to the drive device in a torque-locking manner. The second connection side is connected to the first housing in a torque-proof manner, the drive device being arranged in the first housing and configured to rotate the first connection side relative to the first housing. A further module can be connected to the first and/or second connection side, where the first connection side is optically, electrically, power-electrically and/or fluidically connected to the second connection side, and an optical signal, electrical signal, electrical power, and/or a fluid can be exchanged with the further module via the and/or second connection side.

Abstract: An industrial robot comprises a modular robot arm having a plurality of arm modules, where a rotation transfer device for optical signal transmission is provided in an arm module or between a first and a second arm module. The rotation transfer device comprises an optomechanical rotation interface having a first interface side and a second interface side, which face each other and are substantially rotationally symmetrical and complementary. The first and second interface sides are configured to rotate relative to each other. The first and second interface sides are mechanically mounted with respect to each other, with a radial plain bearing on one interface side and a slide bearing shell complementary thereto on the other interface side. A gap is formed between the first and second interface sides, in the axial direction of the rotation transfer device, across which the optical signal transmission takes place.
