<p><P>PROBLEM TO BE SOLVED: To provide a wire-saving communication system capable of smoothly performing motion control in each operation part of a robot, etc. and saving the number of electric wirings. <P>SOLUTION: The wire-saving communication system 1 is applied to the robot 2 formed suvh that an upper limb part 6, a lower limb part 7 and a head part 8 are installed to a trunk part 9, respectively and each joint is movable, the robot 2 is provided with a first control unit 3 stored inside the robot, a second control unit 4 connected with an actuator, a sensor, etc. and twin cable parts 5 mainly constituted by the first control unit 3, the second control unit 4 and a pair of electric wiring L1, L2. Here, a spread spectrum signal in which various signals such as a control signal are modulated based on a spread spectrum modulation system is transmitted by being superposed on various power supplies to be transmitted from a dynamic power supply part, etc. between the twin cable parts 5. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
