Abstract :
Based on the framework of general constrained robots, a delicate experiment with control of two heavy-duty industrial robots rigidly holding a raw egg is reported. The system possesses smooth transition behavior from free motion to constrained motion when working with unilateral constraints, since a unified no-switching control law is used. This experiment indicates that the robots have the capability to perform very delicate operations with the aid of advanced control algorithms and force feedback. It also reveals potential applications to human-centered robotics
