Working Model of Rocker Bogie Mechanism (Earth Rover)

The Paper work "Rocker Bogie mechanism Geo-survey Rover" deals with attempt of improving the rover from its previous designs. The Geo-survey rover has got to operate rough and harsh environments that it had been designed but several factors restrict its operational capabilities, therefore the focus of our research is to overcome restrictions or to decrease it to within an acceptable range for its smooth performance.. The rover has been completely made from PVC to increase its capability to withstand shocks, vibrations and mechanical failures caused by the tough environment where it's operated on. NASA made and developed this mechanism to use it on Space missions. Whereas these bogies are also preferred by many earthly situations where human interference is needs to be neglected. Usual mobility designs are complicate, using many wheels or legs. It is a multi-wheeled rover capable of travel through rough terrain using an effective higher degree of mobility. Drive train simplicity is the effective mechanical feature of the rocker bogie design, which is accomplished by using only six motors for mobility. All motors are located inside the body where thermal variation is kept to a minimum which increases reliability and efficiency. Six wheels are used because there are few obstacles on natural terrain that need both front wheels of the rover to climb simultaneously. A series of mobility experiments within the agriculture land, rough roads, inclined, stairs and obstacles surfaces concluded that rocker bogie can achieve a long way traverses on field.
