| Research Abstract |
The purpose of this research is to develop a multi-fingered mechanical hand having skill of object grasping and manipulation not only allowing sliding and rotational contacts between the fingers and the object, 'but also, if possible, taking advantage of sliding and-rotational contacts. The, outline of the obtained results is as follows.
(1)Realization'of advanced grasping and manipulation by multi-fingered mechanical hands:
(1.1)Conditions for power grasps for multiple objects have been derived and a method of its optimization was proposed.
(1.2)A dynamic control algorithm of multi-fingered hand for pivoting a heavy object was derived. An experimental result was also given.
(1.3)An optimization method of grasping positions on an object by using a required external force set was proposed and numerical examples were given to show the validity of the approach.
(1.4)A control method for adaptive grasping of objects based on position information from a camera was proposed and some preliminary experiments were performed.
(1.4)A control method for adaptive grasping of objects based on position information from a camera was proposed and some preliminary experiments were performed.
(1.4)A control method for adaptive grasping of objects based on position information from a camera was proposed and some preliminary experiments were performed.
(2)Toward analysis of manipulation skill of human operator and robot:
(2.1)A 2-dimensional haptic'simulator for observing human assembly skill using virtual task space was developed for observing the human skill. Virtual and real peg-in-hole tasks were compared.
(2.2)A 6-dof finger-mounted haptic device was developed for general manipulation of an object by two human fingers.
(2.3)The concept of impedance perception for robots was proposed aiming to build a basic technique for real time perception on the constraint imposed on the robot's end effector.
