Resumen:

This paper shows the geometry and the kinematical model for a compounded serial-parallel wheeled mobile manipulator. The parallel manipulator, Stewart Platform, is an interface that helps the whole system to accomplish stable motion when handling heavy objects and to improve mobility over uneven-terrain by repositioning their center of mass. To evaluate the possibility of tip over, a stability analysis is performed; some criteria are established. Computer simulations and experiments are carried out and the influences of different robotic postures on the tip-over stability are analyzed through simulation results. Copyright © 2011 by ASME.
