“…Subsequently, a prototype of the rover was fabricated with PVC pipes to enhance its shock and vibration resistance, showcasing the mechanism’s flexibility for accommodating length and angle adjustments to meet specific requirements. Utilizing the same material, Shivam et al 56 constructed the mechanism by assembling rocker and bogie links (see Figure 14(b)) and integrating them with a differential bar, followed by electronic integration. The meticulous design ensured precise dimensions, resulting in an impressively balanced mechanism, showcasing its ability to ascend stairs of specific dimensions with remarkable stability.…”

Rovers equipped with Rocker-Bogie mechanisms have emerged as pivotal assets in the domains of interplanetary and terrain exploration. To carry out scientific investigations, Rovers have undergone significant advancements. This review comprehensively examines the progress and innovations associated with the design, manufacturing, and control of these robotic systems. The Rocker-Bogie Mechanism and its kinematic variations available are identified and discussed. Given the importance of kinematic studies, viewpoints on wheel-terrain interaction and framework models for analyses are presented. A key limitation in the analyzed papers was the restriction of choice of design process to the conventional method for which, an approach to design through a Generative Design algorithm has been indicated. The studies indicated the material choice of Titanium and other alloys, the manufacturing choice of Additive Manufacturing which has been analyzed, for which suggestions for advancements and alternatives are highlighted. It was observed that a standard and general procedure to automate the operations of the rovers is still lacking. This review can provide a guide for new advancements in Rocker-Bogie-based rovers.
