Çetin Meriçli, Manuela Veloso, and H. Levent Akın. Complementary Humanoid Behavior Shaping using Corrective Demonstration. In Proceedings of 2010 IEEE-RAS International Conference on Humanoid Robots, December 6-8, 2010, Nashville, TN, USA, 2010.
A humanoid robot can perform a task through a policy mapping from its sensed state to the appropriate task actions. We assume that a hand-coded controller can capture such a mapping only for the core cases of the given task. As the complexity of the situation increases, the harder it is to refine the controller, and such refinements become tedious and error prone. Based on the fact that a human can detect the failures of a robot executing the hand-coded controller, we contribute a corrective learning from demonstration approach to improve the robot performance. Corrections are captured as new state action pairs, and during the autonomous humanoid robot execution, the controller is replaced by the demonstration corrections when the new state is found to be similar to the corrected state. We focus on the Aldebaran Nao humanoid robot and a concrete complex dribbling task in an environment with obstacles. We present experimental results showing an improvement in the humanoid task performance when the corrective demonstration is used in addition to the basic hand-coded controller.
