A process model for part assembly task, using robotic manipulators, is intr
oduced. A neural network control strategy, based on measured force and mome
nt data, for avoiding jamming during part insertion is presented. Fuzzy set
theory, well-suited to the management of uncertainty, is introduced to add
ress the uncertainty problem associated with the part insertion procedure.
The degree of uncertainty associated with the part insertion is used as an
optimality criterion for a specific task execution. The proposed technique
is applicable to a wide range of robotic tasks including part mating with v
arious shaped parts. (C) 2001 Published by Elsevier Science Ltd.
