In this article, work on the experimental identification of a model of
the trajectory generator of a PUMA-560 robot is reported. The model d
eveloped is based on theoretical work reported in the literature and t
he necessary parameters are obtained experimentally. The resulting mod
el is validated versus the corresponding actual robot motions. All exp
eriments are based on the use of a 3D non-contact position sensor to r
ecord the motions of the robot end-effector. (C) 1994 John Wiley & Son
