  • Patent number: 8321054
    Abstract: A method for adjusting a program including program instructions for controlling an industrial robot to carry out work at a plurality of target points on a work object. The robot includes a tool having two arms adapted to clamp the work object and at least one of the arms is arranged movable relative the other arm in an opening and a closing direction, a manipulator adapted to hold the tool or the work object, and a controller controlling the movements of the manipulator and the tool arm and configured to switch between a normal control mode and a compliant control mode in which the manipulator has a reduced stiffness in at least one direction. The method includes moving the manipulator and the tool according to the program instructions until one of the target points is reached.

  • Publication number: 20070280844
    Abstract: The rotary displacement device has a rotating piston and a rotating housing that has a fixed vane. The cylindrical rotor is eccentrically placed in relation to its cylindrical housing. The gas and air flow goes through the hollow-centered shaft via channels in the rotor. The sealing grid in the displacement space is improved to minimize the friction and thereby gain power and better efficiency.
