The centralized formulation for the inertia element of robot dynamics found
by using the composite rigid body is very efficient. However, the correspo
nding formulation for the centrifugal, Coriolis, and gravity elements has n
ot been addressed. Based on certain special motion states of a composite ri
gid body, this article presents the centralized formulation for all the ine
rtial, centrifugal, Coriolis, and gravity elements. This formulation shows
a very direct relationship with the mass, inertia, and Jacobian matrix colu
mns of a composite rigid body. Compared with other modelling formulations,
it requires the minimum computational complexity. Thus, highly efficient co
mplete dynamic modelling of robots can be achieved. (C) 2000 John Wiley & S
