Evolutionary acquisition of handstand from backward giant circle by a three-link rings gymnastic robot

We have already proposed the "rings gymnastic robot" aiming at an application to the gymnastic coaching. We have been also focusing on performance skill acquisition and obtained a skill of a backward giant circle using various models step by step. To apply the skill obtained by the robot to the coaching, many skills collected by a three-dimensional model and experiments are required. However, a handstand has been only realized by a two-link model. Therefore, in this study, we further acquire the performance skill of a handstand from backward giant circle using a three-link model, as a preliminary step toward analyses in three-dimension and experiments.
