We are a group of around ten high school students who are building robots to compete in the GermanOpen and the world championship. The category in which we are participating is called Rescue Robot League (RRL). The aim is to develop a robot that is capable of driving into potentially dangerous terrain, for example, destroyed houses after an earthquake, and check for survivors. We are the only school that has ever participated in these championships for a dozen years. We are currently working on the robot named 'Error 404'. This name corresponds to the phrase 'Error 404 Robot not Found'. The history behind this name is that we started working on this robot just before the Robocup started, so we went there with a robot that basically didn’t exist.
