The system under investigation is the hydraulically driven autonomous large
scale-combined legged and wheeled vehicle, the Anthropomorphically Legged
and Wheeled Duisburg Robot (ALDURO). In this paper a complete mechatronic s
imulation model, realized in the object-oriented programming language C++,
is presented. It contains the mechanical system including an explicit solut
ion of the kinematic loops, a model of the ground contact. and the dynamics
of the complete hydraulic system, as well as a force-based motion control
concept based on an exact input-output linearization using decentralized fo
rce controllers. Some simulation results are shown to demonstrate the funct
ion of the simulation model and the control concept presented.
