Unknown force and unknown contact points for the case in which a planar two-fingered robot hand achieves a stable grasp on an unknown object are identified in this paper. It is shown that the unknown parameters of the grasping system ban be identified by detection of joint angles and torques while the object is manipulated slightly. Finally, it is illustrated by a numerical example that the algorithm of the grasp parameter identification is valid.
