Study of Design and Mobility Approaches in Rocker–Bogie Suspension Systems

Abstract: Navigating rugged, unpredictable terrain is a significant engineering challenge for both off-road vehicles on Earth and rovers on Mars. When the ground becomes extremely rough, traditional suspension systems typically have trouble keeping a car stable and maintaining traction. The rocker-bogie suspension is useful in this situation. It successfully resolves these issues by maintaining all wheels in continuous contact with the ground, which makes it considerably simpler to crawl over big obstacles without tipping. It was first created for space missions. The rocker-bogie mechanism is thoroughly examined in this work. We examine its background, the workings of its mechanics, important design decisions, and the specifics of how it safely climbs over obstacles. Lastly, we examine the practical applications of utilizing this space-age technology.

Keywords: Rocker–bogie suspension, rover mobility, rough terrain navigation, off-road vehicles, suspension systems.
