| Research Abstract |
Multifingered robot hands have the potential to dexterously grasp and manipulate any shaped objects. In this research project, I have investigated the grasp stability of multiple objects and the optimum grasp planning problem based on the analysis. In the planar case, grasps of multiple objects with sliding and rolling contacts between fingers and objects were analyzed. The effects of grasp parameters to the grasp stability were analytically obtained by formulating the partial derivative of the grasp stiffness matrix. In the spatial case, not only the sliding and rolling contacts but also contact surface geometry (metric tensor, curvature and torsion) were considered. An optimum grasp planning algorithm was proposed and its effectiveness was demonstrated by using experimental devices for grasping a single object. In order to include the revolute joints and link lengths of the hands, rotational stiffness model was used. The grasp stiffness matrix was analytically derived on the model.
