Learning of the Dynamic Walk of an Under-Actuated Bipedal Robot: Improvement of the Robustness by Using CMAC Neural Networks

In this paper, we propose a new control strategy based on the use of the neural network CMAC in order to control the under-actuated robot RABBIT. This control strategy is very easy to implement on-line and robust. The first result of the experimental validation is presented.
