  • Patent number: 10016894
    Abstract: A method for controlling a robot in at least one pose of the robot wherein the robot can be operated in either a first mode of operation or a second mode of operation. In the second mode of operation the robot can be moved by manually applying a guiding force to the robot. The method includes determining a distance of a state variable of the robot from a first limit and then triggering a safety response when the distance satisfies a first condition and the robot is operating in the first mode of operation. When the robot is operating in the second mode of operation and the distance satisfies the first condition, the method includes not triggering the safety response, and motorically applying a positioning force to the robot in dependence on the determined distance so that the distance can be reduced when the robot is unobstructed.

  • Patent number: 9746843
    Abstract: A method of safety monitoring for a robot assembly with at least one robot that is configured with a linking function arrangement with at least one first linking function including a fixed and predetermined number of monitoring functions of a monitoring function arrangement. The monitoring functions are logically linked to one another such that the first linking function has a reaction state whenever all of the monitoring functions indicate the violated and/or error state. The first linking function does not have a reaction state whenever any monitoring function from the plurality of monitoring functions does not indicate the violated and/or error state. The reaction state is executed by the controller when all of the monitoring functions are in the violated and/or error state.

  • Publication number: 20160350317
    Abstract: A method and a data processing system for converting at least one first safety configuration file of a control device into a second safety configuration file by means of a converter. Thereafter, the consistency of the first safety configuration file and the second safety configuration file is checked by means of a consistency checking unit. An identifier of the second safety configuration file is initially set to correspond with an identifier of the first safety configuration file, and is changed if an inconsistency is found during the consistency check. If the identifier of the second safety configuration file has been changed and no longer corresponds to the identifier of the first safety configuration file, the control device prevents activation of the second safety configuration file and manipulator.

  • Patent number: 9146174
    Abstract: The invention relates to a belt unit in a wind tunnel balance for motor vehicles, in particular for determining forces and moments acting on a motor vehicle in a wind tunnel, wherein an area exposed to wind is minimized by means of a trapezoidal support, which is raised with respect to a normal zero position, and appropriately adapted test stand covers. The wind-exposed area of the endless belt of the belt test stand can be reduced here to a value which is only slightly above the necessary wheel contact area (tire shuffle). As a result, error forces can be reduced further, so that the result is highly increased measurement accuracy.
