Abstract
Many robots and machines advance into our society recently, and the necessity of making sure of improving safety is more and more increasing. We develop a new shape-changing robotic exterior. This robotic exterior is made of air bladders, and able to change its shape via inflation and deflation. It is soft, light, economical, and not disturbing primarily behavior of an objective which wear this robotic exterior. And we apply it to a real robot and do some experiments in order to evaluate performance of it. Consequently, we show that this robotic exterior has many functions such as shock mitigation and improvement of grasping behavior.
