Inverse versus direct kinematics model based on flatness and escape lanes to control CyCab mobile robot

This paper presents two approaches developed to control our CyCab mobile robot. The first one introduces the notion of virtual axle to determine a flat Inverse Kinematics Model; the second one, based on the Escape Lanes method, uses the Direct Kinematics Model. In the last part of this paper, a comparison between the two methods is carried out in order to validate the inverse model and to discuss the two methods respective advantages.
