[0094] The first drive unit 11 also has a housing 11a. Within the housing 11a of the first drive unit 11, a control unit 11b is arranged, which is also depicted assembled as a circuit board having electronic components. The control unit 11b of the first drive unit 11 also has a first data line input connector 11u connected to the first data line output connector 10x of the control unit 10b of the base 10 via a cable A.sub.11 of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 such that it transmits signals. Via the cable A.sub.11 of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17, the control data of the superordinate decentralised control unit can be forwarded from the control unit 10b of the base 10 to the control unit 11b of the first drive unit 11 to itself be implemented there or to be forwarded via a first data line output connector 11x of the control unit 11b of the first drive unit 11.
[0095] The control unit 11b of the first drive unit 11 further has a second data line input connector 11v connected to the second data line output connector 10y of the control unit 10b of the base 10 via a cable B.sub.11 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19 such that it transmits signals. Via the cable B.sub.11 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19, data originating from a data processing unit 19 can be received from the control unit 11b of the first drive unit 11 via a second data line output connector 11y of the first drive unit 11 and be transmitted or forwarded to the control unit 10 of the base 10.
[0096] The control unit 11b of the first drive unit 11 further has a supply line input connector 11w connected to the supply line output connector 10z of the control unit 10b of the base 10 via a cable C.sub.11 of the second data line C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.16, C.sub.17, C.sub.19 such that it conducts electricity. Via the cable C.sub.11 of the supply line C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.16, C.sub.17, C.sub.19, electrical energy can be made available to the control unit 11b of the first drive unit 11 by means of an electrical voltage of the control unit 10b of the base 10 to supply it with electricity itself or to operate the control unit 11b of the base 11 and to forward the electrical voltage via a supply line output connector 11z of the first drive unit 11.
[0097] The cable A.sub.11 of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 and the cable B.sub.11 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19 are surrounded by a shared shield 11e, within which only the cable A.sub.11 of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 and the cable B.sub.11 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19 are arranged. The signal transmission via the cable A.sub.11 of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 and the cable B.sub.11 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19 can thus be protected from electrical interference, which can improve or guarantee the quality of the signal transmission.
[0098] Both the cable A.sub.11 of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 and the cable B.sub.11 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19 within their shield 11e and the cable C.sub.11 of the supply line C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.16, C.sub.17, C.sub.19 run together in parallel through the hollow shaft 11d of the drive 11c of the first drive unit 11. In this way, a cable-bound connection between the control unit 10b of the base 10 and the control unit 11b of the first drive unit 11 can be achieved, which can also permit the rotational movements.
[0099] The second drive unit 12 is designed and connected to the first drive unit 11 in the same way, see also for example
[0100] The connecting element 17, which has a housing 17a in turn, is rotatably moveably connected to the sixth drive unit 16. An end effector connector 17c is designed on the housing 17a of the connecting element 17 for fixing the end effector 18.
[0101] The connecting element 17 further has the data processing unit 19 already mentioned, which is designed as an image recording unit 19 or as a camera 19 and aligned with its optics 19d to the region ahead of the end effector 18. The image recording unit 19 itself has a housing 19a that encloses a control unit 19b of the image processing unit 19 as a circuit board assembled with electronic components. The control unit 19b of the image recording unit 19 is connected to an image recording sensor 19c of the image recording unit 19 such that it transmits signals (not depicted). The image recording sensor 19c can record the region in front of the end effector 18 through the optics 19d. The information recorded by sensor can be transmitted or sent out as optical data or as image data by the control unit 19b of the image recording unit 19, as is explained in more detail in the following.
[0102] The connecting element 17 also has a control unit 17b as a circuit board assembled with electronic components. The cable A.sub.17 of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 is connected to the first data line input connector 17u of the control unit 17b of the connecting element 17 such that it transmits signals, such that the control data can also reach the control unit 17b of the connecting element 17. The control data can there be used to actuate or operate the end effector 18. The control data can also serve to actuate or operate the image recording unit 19.
[0103] Thus, a continuous arrangement of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 from the base 10 to the connecting element 17 can be achieved, which is formed by the individual cables A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 that together thus represent the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17. In particular, a bus, for example an EtherCAT bus, can thus be formed, which connects the control units 10b, 11b, 12b, 16b, 17b of the base 10, the drive units 11-16 and the connecting element 17 to one another such that they transmit signals. The respective control units 10b, 11b, 12b, 16b, 17n can thus be provided with control data and thus be controlled or operated. Control data meant for other control units 10b, 11b, 12b, 16b 17b can be forwarded from the respective control unit 10b, 11b, 12b, 16b, 17b.
[0104] The cable B.sub.17 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19 is connected to a second data line input connector 17v of the control unit 17b of the connecting element 17 such that it transmits signals. The image data of the image recording unit 19 can be transmitted to a second data line output connector 17y of the control unit 17b of the connecting element 17 via a second data line input connector 19v of the control unit 19b of the data processing unit 19 via a cable B.sub.19 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19. The image data can then be transmitted via all further cables B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19 to the superordinate central control unit by the control unit 17b of the connecting element 17. A signal amplification can take place in the control unit 10b of the base 10 before the image data is forwarded so that the image data can reach the superordinate central control unit with a sufficient strength and quality.
[0105] As data can also be transmitted in the opposite direction from the superordinate central control unit to the control unit 19b of the image processing unit 19 via the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.16, B.sub.17, B.sub.19, the corresponding connections of the control units 10b, 11b, 12b, 16b, 17b, 19b to the base 10, the drive units 11-16, the connecting element 17 and the image recording unit 19 can be described as input connections or output connections in accordance with the corresponding connections of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17.
[0106] The cable C.sub.16 of the supply line C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.16, C.sub.17, C.sub.19 is connected to a supply line input connector 17w of the control unit 17b of the connecting element 17 such that it conducts electricity, whereby the control unit 17b of the connecting element 17 can also be electrically supplied. This electrical supply can be used directly to operate the end effector 18.
[0107] The control unit 17b of the connecting element 17 further has a voltage transformer (not depicted) that receives the electrical voltage directly from the cable C.sub.17 of the supply line C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.16, C.sub.17, C.sub.19 and this electrical voltage is transformed into a second, lower electrical voltage. The second, lower electrical voltage is then guided via a supply line output connector 17z of the control unit 17b of the connecting element 17 via a cable C.sub.19 of the supply line C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.16, C.sub.17, C.sub.19 to a supply line input connector 19w of the control unit 19b of the image processing unit 19, so that the control unit 19b of the image processing unit 19 can be supplied and operated with the second, lower electrical voltage. In this way, due to a short stretch between the voltage transformer of the image processing unit 19 and its control unit 19b, a stable electrical voltage can be made available at the appropriate voltage level. Problems with the stable voltage transmission, for example from the superordinate central control unit, can thus be avoided.
[0108]
[0109] Via an earth line GND and via a 5V voltage line +5V of the parallel-running cable C.sub.19 of the supply line C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.16, C.sub.17, C.sub.19 of the connecting element 17, the second, lower electrical voltage of the control unit 17b of the connecting element 17 can be fed to the control unit 19b of the image recording unit 19.
[0110]
[0111] The two wires Rx, Tx or two conductors Rx, Tx of the cable B.sub.17 of the second data line B.sub.10, B.sub.11, B.sub.12, B.sub.13, B.sub.15, B.sub.16, B.sub.17, B.sub.19 continue from the control unit 17b of the connecting element 17 to the base 10 and beyond to the superordinate central control unit. The cable of the supply line C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.15, C.sub.16, C.sub.17, C.sub.19 also continues from the control unit 17b of the connecting element 17 to the base 10 and beyond to the superordinate central control unit, a 12V voltage line V.sub.cc now running.
[0112] In addition, the cables of the first data line A.sub.10, A.sub.11, A.sub.12, A.sub.13, A.sub.16, A.sub.17 run from the control unit 17b of the connecting element 17 to the base 10 and beyond to the superordinate central control unit, said cables respectively having four wires or conductor which are necessary to carry out the signal transmission of a bus.
