    • A robot control system for sequentially controlling a set of industrial robots for coordinated cooperative operation in accordance with a single general control program. The robot control system comprises a single storage unit storing a single general control program comprising motion instructions for the set of industrial robots, a single reading/compiling unit for separately reading the motion instructions from the storage unit and extracting the motion instructions for each industrial robot, and a plurality of driving units respectively driving the corresponding industrial robots in accordance with the motion instructions. The single general control program facilitates sequentially coordinating motion instructions for controlling the set of industrial robots so that the industrial robots will not interfere each other during the cooperative operation, finding errors in the instructions, and modifying the general control program to cope with changes in the process controlled by the robot control system.

    • The purpose of the present invention is to have the angles of each of the drive shafts of the first articulated drive system infallibly reach the angle of the work completed position, while maintaining the rate of movement and position of the working parts of an articulated robot. If exception conditions are not satisfied, the drive shafts of first and second articulation drive systems are driven individually (S64) on the basis of interpolated points calculated in step 5 (S5). After exception conditions are satisfied (Yes side of S61), until the working parts reach the work completed position (No side of S12), the angle of each of the drive shafts of the first articulated drive system required to vary each of the drive shafts of the first articulated drive system in a linear manner with the angle at the work completed position as a target is calculated (S8), and the angle of each of the drive shafts of the second articulated drive system is calculated on the basis of the position of the working part at the interpolated point calculated in step 5 (S5) and the angle of each of the drive shafts of the first articulated drive system as calculated (S9), and the drive shafts of the first and second articulated drive systems are driven according to said calculation results (S11).
    • 本发明的目的是使第一关节式驱动系统的每个驱动轴的角度可靠地达到工件完成位置的角度,同时保持铰接式机器人的工作部件的运动速度和位置。 如果异常条件不满足,则基于步骤5(S5)中计算出的内插点,分别驱动第一关节传动系统和第二关节驱动系统的驱动轴(S64)。 在满足例外条件(S61的是侧)之后,直到工作部件到达工件完成位置(S12的否侧),第一铰接驱动系统的每个驱动轴的角度需要改变每个驱动轴 计算出第一铰接驱动系统以作为目标的作业完成位置处的角度的线性方式(S8),并且基于位置来计算第二铰接驱动系统的每个驱动轴的角度 (S5)中计算的插补点处的工作部分和第一铰接驱动系统的每个驱动轴的角度(S9),并且驱动第一和第二铰接驱动系统的驱动轴 根据所述计算结果(S11)。
