ABSTRACT: The rocker-bogie suspension mechanism it's presently NASA's favoured style for wheeled mobile robots, primarily as a result of its sturdy capabilities to upset obstacles and since it uniformly distributes the payload over its six wheels in any respect times. although it's several benefits once handling obstacles, there's one major defect that is its low average speed of operation, creating the rocker-bogie system not appropriate for things wherever high-speed traversal hard-flat surfaces square measure required to hide massive areas in brief periods of your time, principally thanks to stability issues. Our proposal is to extend the soundness of the rocker-bogie system by increasing its support plane figure, creating it additional stable and flexible whereas moving at high speed, however keeping its original robust sizes against obstacles. The Rocker-Bogie quality system was designed to be used at slow speeds. It’s capable of overcoming obstacles that square measure on the order of the dimensions of a wheel. However, once surmounting a large obstacle, the vehicles motion effectively stops whereas the front wheel climbs the obstacle. once operational at low speed (greater than 10cm/second), dynamic shocks square measure reduced once this happens. for several future planetary missions, rovers can ought to operate at human level speeds (-1m/second), Shocks ensuing from the impact of the front wheel against associate degree obstacle might injury the payload or the vehicle. we are going to develop methodology/away/a technique} of driving a rocker-bogie vehicle in order that it will effectively step over most obstacles instead of impacting and rising over them Most or the advantages of this method is achieved with none mechanical modification to existing styles solely a amendment au fait strategy. Some mechanical changes square measure recommended assembling the utmost profit and greatly increasing the effective operational speed of future rovers.
