Next, a description is given of activities of the robot remote control apparatus 1 and the robot apparatus 2, which are thus composed, with reference to FIG. 25 through FIG. 29. FIG. 25 is a flowchart depicting a transmission behavior in the robot remote control apparatus 1, FIG. 26 is a flowchart depicting a receiving behavior (reaction control) in the robot remote control apparatus 1, FIG. 27 is a flowchart depicting a transmission behavior in the robot apparatus 2, and FIG. 28, FIG. 29 and FIG. 30 are flowcharts depicting receiving behaviors in the robot apparatus 2. Herein, FIG. 25 and FIG. 26 depict behaviors of the CPU 31, and FIG. 27 through FIG. 30 depict behaviors of the CPU 71.

In FIG. 25, first, a dialing connection is made from the mobile transmission unit 35 depicted in FIG. 2, and a completion signal of PHS dialing connection is transmitted to the CPU 31 via the mobile transmission card 36 and the interface portion 32a, wherein the CPU 31 determines that controlling is available, and notifies the display unit portion 5 of its availability (S1). Next, the CPU 31 receives input of control data (the control data including a turn angle, rotation angle, ON and OFF of instruction switches) from the remote instruction unit 4 (S2), formats the control data and outputs the same to the mobile transmission unit 35 (S3). Behaviors in Steps S2 and S3 are repeated until the output of all the control data is completed (S4).

Next, using FIG. 26, a description is given of a receiving behavior in the robot remote control apparatus 1.

In FIG. 26, the CPU 31 depicted in FIG. 2 reads received data from the mobile transmission unit 35 (S11), and carries out reaction control of the steering arms 141 and 142 of the remote instruction unit 4 on the basis of the received data (S12).

Next, using FIG. 27, a description is given of a transmission behavior in the robot apparatus 2.

In FIG. 27, the CPU 71 depicted in FIG. 3 receives input of sensor signals from the sensor group 109 (S21), formats the sensor signals to the sensor data and outputs the same to the mobile transmission unit 75 (S22). Behaviors of Steps S21 and S22 are repeated until processing of all of the sensor signals is completed (S23).

Next, using FIG. 28 through FIG. 30, a description is given of a receiving behavior in the robot apparatus 2.

In FIG. 28, first, the CPU 71 depicted in FIG. 3 reads received data from the mobile transmission unit 75 as various types of control data (S31) and controls the working arms (S32) and travelling (S33).

With reference to FIG. 29, a description is given of control of the working arms in Step S32.

In FIG. 29, first, the CPU 71 depicted in FIG. 3 determines whether the control is remote control (S41), and when remote control is determined, the CPU 71 receives control data from PHS (S42). Next, the CPU 71 determines whether or not operation prohibition is valid (S43) and determines whether or not any position instruction is valid (S44). Where the operation prohibition is valid or where no position instruction is valid, the CPU 71 finishes processing. Where the operation is not prohibited and a position instruction is valid, the CPU 71 next determines whether the deviation is positive or negative (S45). If the deviation is positive, the CPU 71 instructs POSITIVE (clockwise rotation of motor, and cylinder movement in the positive direction) to the driver unit for motors 93 and hydraulic servo valve unit 94 (S46), and if the deviation is negative, the CPU 71 instructs NEGATIVE (counterclockwise rotation of the motor, and cylinder movement in the negative direction) thereto (S47). Next, the CPU 71 determines whether a speed instruction is valid (S48), and if the speed instruction is valid, a speed responsive to the deviation is instructed (S49).

Where it is determined in Step S41 that no remote control is valid, the CPU 71 starts the on-board instruction unit 8 (S50), determines whether operation prohibition is valid (S51), and determines whether a position instruction is valid (S52). Where the operation prohibition is valid or no position instruction is valid, the processing ends. Where the operation is not prohibited, and a position instruction is valid, the CPU 71 next determines whether the deviation is positive or negative (S53). If the deviation is positive, the CPU 71 instructs POSITIVE (clockwise rotation of motor, and cylinder movement in the positive direction) to the driver unit for motors 93 and hydraulic servo valve unit 94 (S54), and if the deviation is negative, the CPU 71 instructs NEGATIVE (counterclockwise rotation of the motor, and cylinder movement in the negative direction) (S55) thereto. Next, the CPU 71 determines whether a speed instruction is valid (S56), and if the speed instruction is valid, a speed responsive to the deviation is instructed (S57).

Using FIG. 30, a description is given of travelling control in Step S33, which is depicted in FIG. 28.

In FIG. 30, first, the CPU 71 depicted in FIG. 2 determines whether the remote control is valid (S61). Where the CPU 71 determines that the remote control is valid, it receives control data from a PHS (S62). Next, the CPU 71 determines whether travelling prohibition is valid (S63), and determines whether a travelling instruction is valid (S64). If the travelling prohibition is valid, the same is notified, and the processing ends (S70). If no travelling instruction is provided, the processing immediately ends. If the travelling prohibition is not valid, and a travelling instruction is provided, the CPU 71 next determines whether the travelling is forward (S65). In the case of forward travelling, the CPU 71 instructs FORWARD to the driver unit for motors 93 and hydraulic servo valve unit 94 (S66), and in the case of rearward, rearward travelling is instructed (S67). Next, the CPU 71 determines whether a speed instruction is valid (S68). If a speed instruction is provided, the CPU 71 outputs an instruction speed (S69).

Where the CPU 71 determines in Step S61 that no remote control is valid, the CPU 71 starts the on-board instruction unit 8 depicted in FIG. 1 and FIG. 3 (S71), and determines whether travelling prohibition is valid (S72) and whether a travelling instruction is provided (S73). If the travelling prohibition is valid, the same is notified, and the processing ends (S79). Where the travelling prohibition is not valid, the processing immediately ends. Where the travelling prohibition is not valid, and a travelling instruction is provided, next, the CPU 71 determines whether the travelling is forward (S74). In the case of forward travelling, the CPU 71 instructs FORWARD to the driver unit for motors 93 and hydraulic servo valve unit 94 (S75), and in the case of rearward, rearward travelling is instructed (S76). Next, the CPU 71 determines whether a speed instruction is valid (S77). If a speed instruction is provided, the CPU 71 outputs an instruction speed (S78).
