The dynamic equations of the motion with multiple contact constraints are derived. The dynamic equations are transformed into two subspaces (the constrained and constraint-free subspace) using singular value decomposition of the constraint equations. Each force and position controller is developed based on the orthogonality of these two subspaces. A hybrid controller is proposed from the new coordinates. Its stability is proved analytically under the quasi-static condition. An experimental study is carried out to justify the feasibility and application of the proposed ideasKeywords
