Abstract. Recent progress in sensor technology, data processing and integrated actuators has made the development of miniature flying robots fully possible. Micro VTOL 1 systems represent a useful class of flying robots because of their strong capabilities for small-area monitoring, building exploration and intervention in hostile environments. In this paper, we emphasize the importance of the VTOL vehicle as a candidate for the high-mobility system emergence. In addition, we describe the approach that our lab 2 has taken to micro VTOL evolving towards autonomy and present the mechanical design, dynamic modelling, sensing, and control of our indoor VTOL autonomous robot OS4.3

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.
