Patent number: 5754433Abstract: The computer-aided design system of the present invention is characterized in that a grasping force sensor 4 is mounted on that operating bar 3 at the front end of a manipulator 1 which is grasped directly and operated by an operator, and that the mechanical response characteristics of the system are varied on the basis of an output from the grasping force sensor 4. That is, the rigidity on the part of the manipulator is increased in response to a high grasping force during operation, since the rigidity of the hand is also high; and the rigidity on the part of the manipulator is decreased for a low grasping force during operation, since the rigidity of the hand is also low. In scenes in which a space on a computer screen defining no shapes is crossed by a cusor on the screen, a weak grip will lower the rigidity on the part of the manipulator, thus achieving the feeling of a smooth operation.Type: GrantFiled: March 27, 1996Date of Patent: May 19, 1998Assignee: Director-General of Agency of Industrial Science and TechnologyInventors: Yukio Fukui, Hiroshi Yokoi, Makoto Shimojo

Patent number: 5116180Abstract: In a human-in-the-loop robotic control loop, the constrained forces and moments at the gripper (also called hand or end effector) of the manipulator are measured by a force-mement sensor. The resulting force and moment signals are scaled and fed as input voltages to motors in a hand controller to provide torques which oppose deflection of the hand controller. Thus, the operator feels the opposing torques which are proportional to the magnitude of the constrained forces and moments. The force feedback loop may be opened to selectively provide a passive control loop. In either the active or passive mode, the hand controller position signals may be selectively mapped to either gripper position signals or gripper velocity signals in order to control movement of the gripper in the desired manner.Type: GrantFiled: May 3, 1990Date of Patent: May 26, 1992Assignee: Spar Aerospace LimitedInventors: Patrick T.
