【Abstract】 To solve the problem of internal force control in the coordinated transporting of dual robots, based on the master-slave motion framework and the introduced internal force model, an internal force control strategy of slave robot single-ended adjusiment based on adaptive impedance model is proposed. The simulation and experimental task is designed, i.e., the dual robots carrying the box to complete the trajectory of lifting, moving and lowering, and controlling the internal force in z-axis of object frame. The change of the internal force of the object is simulated. The sinusoidal position error signal in the z-axis of the object frame is given and verified to complete the physical experiment of coordinated transporting of dual robots. The results show that the proposed internal force control strategy can effectively control the internal force of the object at the desired level.更多还原
