Effects of body extension and its relationship to learning in robots is not clear even though lots of research have been done. In this paper, to reveal these characteristics, we make simulation robots and attach some rigid bodies to them in order to extend their bodies. Through the interaction in game, extensions increase the average winning percentage of some rule sets. But it does not affect the winning percentage of a specific rule set. Also, each extension has its own collision property and its average collision time is not proportional to the surface area of extensions. We use simulation environment which cause physical effects to robots by using physics engine.
