| In this paper we consider
the mobile robot parking problem, i.e., the stabilization of a wheeled
vehicle to a given position and orientation, using only visual feedback
from low-cost cameras.We take into account the practically most relevant
problem of keeping the tracked features in sight of the camera while
maneuvering to park the vehicle. This constraint, often neglected in
the literature, combines with the non-holonomic nature of the vehicle
kinematics in a challenging controller design problem.We provide an
effective solution to such a problem by using a combination of previous
results on non-smooth control synthesis and recently developed hybrid
control techniques. Simulations and experimental results on a laboratory
vehicle are reported, showing the practicality of the proposed approach. |
