Learning to Steer on Winding Tracks Using Semi-Parametric Control Policies

The following results show steering behaviors that were learned using our semi-parametric control policy representation. The vehicles controlled include a car, single-trailer truck, and double-trailer truck. Of particular interest are the backwards-driving single and double-trailer trucks given that the trailer will tend to jack-knife without corrective action. The Variable Width Track video shows the ability of the policy to generalize to a track of width different from that which was used for training.  More details can be found in our ICRA 2005 paper and my MSc thesis.
