A working robot, which is able to perform a required operation by locating a tool on a working position of a moving object, comprises a robot body moving with the object according to the movement of the object with more than one degree of freedom; an actuator mounted on a free end of the robot body and including a tool mounting unit, on which the tool is mounted, connected by a passive joint which reacts passively to small displacement of the object for locating the tool on the working position; and a control device for controlling the robot body, the actuator, and the tool.

An apparatus for measuring jaw motion has a pair of fixed marker attached to both sides of face of patient, a pair of movable markers disposed to face the fixed marker in a spaced distance and to move in unison with the movement of the lower jaw of patient, four cameras recording the three-dimensional movement of the movable marker relative to the fixed marker, as lower jaw moves, and personal computer for receiving and processing the image signals fed from connected cameras. The apparatus can accurately measure the location of the center of patient's jaw motion and the moving track thereof with stereo vision processing of the image signals obtained from camera.

A robot hand finger makes a hooking movement similar to that of the human fingers with less number of driving units by installing a 4-joint link. A robot hand includes several fingers and 4-joint link in order to implement a horizontal movement of the fingers. A robot hand selectively drives a hooking movement and a horizontal movement of fingers with less number of driving units by having a clutch unit. A robot hand includes fingers with a strain gage and is able to control a grasping force by using a value measured by the strain gage.
