ABSTRACT:
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. If a slight and precise change in the shape on the screen is desired, a firm grip will make the rigidity of the manipulator high, thus achieving meticulous actions of the operating bar with the same external force.
