This mobile robot is used during rescue operations following serious catastrophes such as earthquakes and bomb or gas explosions. The robots inspect collapsed buildings or look for victims, for example. The high-tech rescue workers have to be fast and light on the one hand, and highly mobile on the other. In addition, the components used must remain functional even under adverse conditions. The developers focused mainly on the drive of the robot. This permits the robot to move in any direction whatsoever. The sturdy iglidur® plain bearings as well as igubal® flange bearings and spherical axial bearings from igus® guarantee a perfect drive, even under the most adverse of conditions.
