Abstract:
In this draft, we present the formulation of bilevel optimization for performing robust pivoting manipulation. We derive analytical expressions for stability margin provided by friction during pivoting manipulation. This margin is then used in the bilevel trajectory optimization to design an open loop controller that maximizes this stability margin to provide robustness against uncertainty in physical properties of the object. The proposed method has been tested on several pivoting manipulation scenarios
