Fine manipulation with multifinger hands
The existence of two- and three-finger grasps in the presence of arbitrarily small friction is shown for two- and three-dimensional smooth objects using a simple technique. No convexity of the objects is assumed. The existence of finger gaits for rotating a planar object using three and four fingers is proved. Additional results for smooth convex objects which describe two different finger gaits using four fingers are presented.
