Abstract:
The invention relates to an industrial robot device. The device has a swivel with attachment means for the attachment of a tool. According to the invention the attachment means includes at least two different attachment devices for two different kinds of tools. A first attachment device (9, 10) includes positioning means (9) defining a certain angular position of an attached tool relative to the swivel. A second attachment device (10) is arranged for allowing an arbitrary angular position of an attached tool relative to the swivel. The invention also relates to an industrial robot that is provided with the invented device and to a method for manipulating objects.
Abstract:
A manipulator of a parallel kinematic structure with a stationary element (2) comprising a base (10) adapted to be the load-carrying part of the manipulator, an enclosure (6) and attachment means (17). The base comprises a first part (15) and a second part (16) comprising the attachment means (17). The second part is adapted to frame said first part (15). The first part (15) and the second part (16) are connected and arranged such that the first part (15) is completely enclosed within the enclosure (6), and the second part (16) is partially exposed to a space outside said enclosure (6).
Abstract:
A method for controlling a multi-axis industrial robot or manipulator arranged with a robot control unit, the robot or the control unit also comprising at least one first computer (10) running a servo controller. A motion limit is configured for at least one axis of said robot arm. A reference signal (1) for a robot position is sent to a robot controller (13) together with a measurement of a position of said robot arm. The reference position is processed and the measured position and the processed reference position are then compared in an evaluator (4) for the purpose of limiting the motion of an arm of said robot.

Abstract:
An arm part (204) of a manipulator of an industrial robot has at each end thereof means for connecting the arm part to a gear and means for stiffening the end region of the arm part. At least one aperture (223, 224) is arranged in a hollow structure (221 ) of said stiffening means for providing access to connecting members (212).
