Robot double-arm synchronizing control method and system

The invention discloses a robot double-arm synchronizing control method and system. The method includes the steps that an electric control system central processing unit receives the speed response value fed back by a speed collector, the first speed response value, the second speed response value and the difference value absolute value of the given speed value are computed, and the first difference value absolute valve and the second difference value absolute value are obtained correspondingly; when both the first difference value absolute value and the second difference value absolute value are in the first error range, the difference valve absolute value between the first speed response value and the second speed response value is computed, and the relative difference value absolute value is obtained; when the relative difference value absolute value is in the second error range, a left hand drive motor and a right hand drive motor are controlled to operate. Compared with the prior art, the robot double-arm synchronizing control method and system effectively solve the problems that it is difficult to coordinate double arms of a robot, and the synchronizing efficiency is low and improve the synchronizing control performance of the double arms of the robot.
