International Journal for Research in Applied Science and Engineering Technology, 2022 Abstract: The Rocker-Bogie Mobility System was design to be used at slow speeds. It is capable of overcoming obstacles that are on the order of the size of the wheels. However, when surmounting a sizable obstacle, the vehicle motion effectively stops while the front wheel climbs the obstacle.
