A manipulator having a plurality of articulations to be controlled with a given destination value of position and orientation, has a finite difference unit for obtaining a finite difference between the destination value and a present value for each articulation, and a fuzzy inference determination unit for executing a fuzzy inference for each articulation by using the finite differences and determining a command value for each articulation. The position of the manipulator terminal may be obtained on the basis of each articulation angle data, video data from a TV camera, or data from an ultrasonic sensor.

Why it's free to use
- Filed June 7, 1990 and granted May 31, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 7, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 7, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
