Description

In this paper, an analysis of contact forces in quasi-static manipulation under rigid-body mechanics is studied. To evaluate the contact forces, we introduce a modified version of constraint on friction forces, which was originally derived for statics of power grasps by Omata et al. Furthermore, using the constraint, we also present a robustness measure for quasi-static graspless manipulation such as pushing and tumbling. The measure evaluates how much the object can resist external disturbances without changing its motion. We can calculate the measure approximately by solving linear programming problems. We show some numerical examples to prove that our proposed method can evaluate robustness of graspless manipulation more accurately than previous methods, and experimentally verify the calculation results.
