  • Publication number: 20050027394
    Abstract: The invention concerns a method and a system for controlling a first robot and at least one other robot, the at least one other robot being calibrated relative to the first robot by the determination of at least one coordinate transformation of the first robot relative to at least one other robot and said at least one transformation is stored in a control device of the other robot, wherein also the first robot is calibrated relative to the other robot by the determination of at least one independent coordinate transformation and said at least one independent transformation is stored in a control device of the first robot.

  • Patent number: 6804580
    Abstract: A system for controlling a plurality of robots and a method for controlling said system. Said system comprises a plurality of controllers, each having an associated motion system adapted to control attached robots, with each motion controller being able to receive motion instructions from at least one motion instruction source and at least one of said motion instruction sources being a control program, as well as a computer network over which said controllers communicate. In this way, the invention can be applied to solve problems which are commonly encountered in coordination activities such as load sharing, mating of parts while processing, fixtureless transfer, teaching, manual motion of coordinated operations, and time coordinated motion.

  • Publication number: 20040083027
    Abstract: To improve the exchange of data between controls of machines, particularly robots, the invention provides a method for the exchange of such data, wherein a first control produces an instruction to be transmitted with data to be sent to a second control and with an identification representing said second control, wherein the instruction to be transmitted is provided with an identification of the first control, wherein the first control sends the instruction to be transmitted to the second control, wherein the second control evaluates the data of the instruction and wherein the second control provides the first control with an acknowledgement.

  • Patent number: 6691969
    Abstract: Described is an apparatus for adjusting the inclination of a seat squab (12) of a vehicle seat (10), wherein the device (18) has a rocker (20) with an upper and a lower rocker element (22, 24) which are pivotably movably connected together by lateral bearing bushes (36). Fixed to the upper rocker element (22) is a toothed bridge (38) with mutually oppositely disposed bridge tooth arrangements (40) which are concentric with respect to the bearing bushes (36). Provided between the two bridge tooth arrangements (40) of the toothed bridge (38) are two toothed sliders (64) with slider tooth arrangements (66). Provided between the two toothed sliders (64) is a locking member (48) rotatable about a rotary axis (26) extending through the bearing bushes (36). The two toothed sliders (64) are linearly movably guided on the lower rocker element (24) between a locking position and a release and adjusting position.

  • Publication number: 20040030452
    Abstract: A method for the synchronous control of several manipulators, such as several industrial robots, is characterized in that control units of specific manipulators exchange control information according to the data structures contained in a corresponding control program, through which control units to be synchronized and synchronization points in the control programs taking place there can be clearly identified, and in that on reaching and synchronization points the program sequence in the control units to be synchronized is continued according to the contents of the data structures in conjunction with the already exchanged control information or stopped until corresponding information arrives from other control units to be synchronized.

  • Publication number: 20040030453
    Abstract: A method for the synchronous control of a plurality of handling devices, such as industrial robots, is characterized in that a control command to be implemented by controls of the handling devices participating in a synchronization is initiated on a random control and is subsequently further processed therein as a function of the nature of the command.

  • Patent number: 6294990
    Abstract: A display device for a motor vehicle for displaying at least two related display parameters with the help of scale segments. At least one scale segment can be controlled to differentiate the two display parameters so that color, contrast and/or brightness can be differentiated in comparison with the other scale segments.
