point on the base platform (preferably its center of
mass) represents the translational motion of the
system (Moosavian and Papadopoulos, 2004). As
shown in Figure 11, the kinematics of the mobile
manipulator system can be developed by using a set of
body-fixed geometric vectors to formulate the position
and velocity with respect to a representative point p.
The motion of the center of mass (CM) is used to
describe the system translation with respect to the inertial
frame of reference, Og-XgYgZg. The CMs of each
