Abstract

The invention provides an industrial robot collaborative interaction method and system. The industrial robot collaborative interaction method comprises the following steps that an industrial robot kinematics and dynamics model is established, and a base force-torque measuring coordinate system is determined; length parameters and mass distribution characteristic parameters of connecting rods of anindustrial robot are bound; joint motion parameters of the industrial robot are measured, and filtering processing is carried out; according to the joint motion parameters of the robot, motion parameters of all the connecting rods of the industrial robot are solved; according to the motion parameters of all the connecting rods of the industrial robot and the mass characteristic parameters of theconnecting rods of the industrial robot, the free motion reaction couple of all the connecting rods are calculated, and the reaction couple which is transmitted to a robot base is solved; the fixed reaction of the base is measured, and filtering processing is carried out; the projection of the interaction external force under the coordinate system of the base is calculated; and the interaction motion of the industrial robot is controlled. The method and the system can be applied to all the robots with series structures, and through three sub modes set in the method, the basic interaction capability requirement in the human-machine cooperation process can be met on the premise of ensuring the human-machine safety.
