We propose in this work the first model-based robust control method for a team of underactuated manipulators jointly manipulating a load. The method is based on feedback linearization of the nonlinear dynamic coupling between the torques applied at the actuated joints and the Cartesian acceleration of the load, combined with a variable structure controller. Singularities in the control method are addressed, and a sufficient condition for a singularity-free controller implementation is obtained. Simulation and experimental results are presented to validate the theory presented.
