BendIT { An Interactive Game with two Robots

In this paper we report on an interactive game with two robots and review its components. A human user uses his torso move- ments to steer a Robotino robot along a pre-dened course. Our domes- tic service robot Caesar acts as a referee and autonomously follows the Robotino and makes sure that it stays within a corridor along the path. If the user manages to keep the Robotino within the corridor for the whole path he wins. The game can be used, for example, to engage people in physical training such as a rehabilitation after an injury. It was designed and implemented as a student project in winter term 2011/2012.
