Abstract (in Japanese) (See Japanese page) 
(in English) Adaptability to the environment is crucial for mobile robots, because the circumstance, including the body of the robot, may change. A robot with a large number of degrees of freedom possesses potential to adapt to such circumstances, but it is difficult to design a good controller for such a robot. In this study, we apply our RL method called the CPG-actor-critic method to the control of a looper-like robot we have developed. Experimental
results demonstrate acquisition of a vermicular forward motion exhibiting the best performance of the actuator, and acquisition of recovery from a malfunction of an actuator.
