This article deals with a real-time model inverting system. The mathem
atical inverting problem is no longer solved with a mathematical algor
ithm but through the design of the system control itself. The control
algorithm is issued from human knowledge. The stability of this system
is proved, and the properties are discussed. This system can be used
where a geometric model should be inverted in real time, especially fo
r redundant robots. (C) 1995 John Wiley & Sons, Inc.
