The need to develop a highly stable suspension system capable of operating in multi terrain surfaces while keeping all the wheels in contact with the ground. To design a mechanism that can traverse terrains where the left and right rockers individually climb different obstacles. To sustain a tilt of over 50 degree without tipping over the sideways. Rocker bogie are important for conducting scientific analysis of objectives that are separated by many meters to tens of kilometers. Current mobility designs are complex, using many wheels or legs. They are open to mechanical failure caused by the harsh environment on Mars. A six wheeled rover capable of traversing rough terrain using an efficient high degree of mobility suspension system. Six motors are located inside the body where thermal variation is kept to a minimum, increasing reliability and efficiency. Six wheels are used because there are few obstacles on natural terrain that require both front wheels of the rover to climb simultaneously. A series of mobility experiments in the agriculture land, rough roads, inclined, stairs and obstacles surfaces concluded that rocker bogie can achieve some distance traverses on field.
