Position and Force Control of Two Constrained Robotic Manipulators

In this paper, the problem of controlling two robotic manipulators handling a constrained object is addressed. First, a reduced order dynamic model of the system is obtained. Using this model, a controller that guarantees the asymptotic convergence of the position, the internal force, and the constraint force to their desired values is proposed. Simulation results for two three-link planar manipulators moving a constrained object demonstrate the effectiveness of the proposed controller.
