Abstract:
In this paper, we develop a new algorithm for computing force-closure grasps of two-dimensional (2D) objects using multifingred hand. Assuming hard-finger point contact with Coulomb friction, we present a new condition for
multi-finger to form force-closure grasps. Based on the central axis of contact wrenches, an easily computable algorithm for force-closure grasps has been implemented and its efficiency has been demonstrated by examples.
