Also it has 4 Star-Wheels that have been designed for traversing stairs and obstacles. Each Star-Wheel has two rotary axes. One is for its rotation of 12 regular wheels when MSRox moves on flat surfaces or passes over uphill downhill and slope surfaces. The second one is for the rotation of Star-Wheels when MSRox climbs or descends stairs and traverses obstacles. The MSRox mechanism is similar to Stepping Triple Wheels Saltaren R. R. Aracil and AIMARS Advanced Intelligent Maintenance Saranli U. M. Buehler . The Stepping Triple Wheels concept for mobile robots allows optimal locomotion on surfaces with little obstacles. AIMARS is a maintenance robot system for nuclear power plants which can conduct simple works instead of workers. The presented version of MSRox can not steer and the new version of it will be equipped with the steering capability in near future. In doing so the six left and six right wheels should be driven individually which causes the robot to skid steer similar to PackBot. Discussion Of The Locomotion Concepts Four main principles - rolling walking crawling and jumping - have been identified for full or partial solid state contact. However additional locomotion principles without solid state contact could be of interest in special environment. Most of the mobile robots for planetary exploration will move most of their time on nearly flat surfaces where rolling motion has its highest efficiency and performance. However some primitive climbing abilities are required in many cases. Therefore hybrid approaches where for example rolling motion is combined with stepping are of high interest.
