  • Patent number: 9902065
    Abstract: A method for altering an initially predetermined path of a robot arrangement having at least one robot includes selecting a portion of the initially predetermined path, altering the selected portion of the path, and predetermining an altered path based on the altered portion of the path. A deviation between the initially predetermined path and the altered path is determined, and a reaction is triggered if the deviation fulfills a predetermined condition for a reaction. In another aspect, a computer programming product, when executed by a computer, causes the computer to select a portion of the initially predetermined path, alter the selected portion of the path, predetermine an altered path based on the altered portion of the path, determine a deviation between the initially predetermined and the altered path, and trigger a reaction if the deviation fulfills a predetermined condition for a reaction.

  • Patent number: 9902072
    Abstract: A telepresence system includes a man-machine interface and a teleoperator configured to communicate bidirectionally with the man-machine interface via a communications channel. The teleoperator performs actions based on first signals generated due to a manual operation of the man-machine interface and transmitted over the communication channel, and sends second signals to the man-machine interface over a second communication channel. At least one buffer device buffers signals transferred through the communication channel and releases the signals delayed so that the signals coming from the man-machine interface and the signals coming from the teleoperator each are transmitted through the communication channel with an effective constant time delay.

A first drive rotatably connecting the first and second links includes a drive housing, a rotor, and a stator connected to the drive housing. The drive housing is fastened to the first housing of the first link and forms an external wall of the robotic arm. The transmission associated with the first drive includes an input link that is joined with the rotor of the first drive. An output of the first drive is connected to a flange that is fastened to the second housing and rotatable relative to the drive housing.

  • Patent number: 9827674
    Abstract: A method for the conditional stopping of at least one manipulator and a manipulator assembly. The manipulator travels along a path which has a stopping point. In order to be able to stop the manipulator at the stopping point, a braking point on the path is calculated as a function of a speed of the manipulator. If the status of a travel condition variable necessitates braking of the manipulator in the event of exceeding the braking point, the manipulator is braked.
