Paper accepted @ SIAM CT13
Our partial characterization of minimum time trajectories for a car-like robot with one trailer has been accepted at SIAM Control and Its Applications (CT) 2013. Our analysis proves that the robot, on a time optimal path, has to follow a merging curve to straighten up its trailer after a minimum radius turn in order to be able to join a straight line motion.
