Abstract: A parallel kinematic robot including a base unit, a platform movable in relation to the base unit about a plurality of main axes, two independently movable actuating arms connected between the base unit and the movable platform for moving the platform in relation the base unit, a tool holder rotatably connected to the platform to allow rotation of the tool holder in relation to the platform about a first auxiliary axis, a motor for driving the first auxiliary axis, located in the base unit, and a gear unit. The gear unit includes a first gearbox located in the base unit and a second gearbox located in the platform.

Abstract: A wrist device for an industrial robot, the wrist device including a wrist housing; a first member; a second member; a first pinion rotatable about a first pinion axis; a first crown wheel for driving the first member, the first crown wheel meshing with the first pinion; a second pinion rotatable about a second pinion axis; a second crown wheel for driving the second member, the second crown wheel meshing with the second pinion; and an integral pinion housing fixedly attached to the wrist housing, the pinion housing supporting the first pinion for rotation about the first pinion axis and supporting the second pinion for rotation about the second pinion axis. An industrial robot including a wrist device, and a method of assembling a wrist device for an industrial robot, are also provided.

Abstract: A method for controlling a multi-axis industrial robot or manipulator arranged with a robot control unit. The robot or the control unit includes at least one first computer running a servo controller. A motion limit is configured for at least one axis of the robot arm. A reference signal for a robot position is sent to a robot controller together with a measurement of a position of the robot arm. The reference position is processed and the measured position and the processed reference position are then compared in an evaluator for the purpose of limiting the motion of an arm of the robot.
