What is a rocker bogie Rover?
The rocker-bogie design is unsprung and uses split rather than full-width axles, allowing the rover to climb over obstacles (such as rocks) that are up to twice the wheel's diameter in size while keeping all six wheels on the ground.
Jan 6, 2017 · The primary mechanical feature of the rocker bogiedesign is its drive train simplicity, which is accomplished by using only two motors for mobility. Both motors are located inside the body...
The rocker-bogie suspension is a mechanism that, along with a differential, enables a six-wheeled vehicle to passively keep all six wheels in contact with a surface even when driving on severely uneven terrain (Figure

Over the past decade, the rocker-bogie suspension design has become a proven mobility application known for its superior vehicle stability and obstacle-climbing capability [1,2]. Following several technology and research rover implementations, the system was successfully flown as part of Mars Pathfinder’s Sojourner rover [3]. When the Mars Explorat...
Determination of how the rocker-bogie suspension could be “broken” to enable it to stow within the allotted space was the first challenge faced in the design of the sub-system. As the name would suggest, the two primary components of this type of suspension are the rocker and bogie (see Figure 4). These two structural elements are connected via a f...
The desire to create a suspension that efficiently absorbs energy leads to structural members that are thin walled box beams. A box beam design is a mass efficient geometry for components subjected to both bending and torsional loads. The beams are also tapered wherever possible to increase mass savings. Based on these desired design features, the...
Learn how the rocker-bogie suspension system enables the rover to traverse uneven terrain and absorb impact loads on Mars. The paper describes the design challenges, deployment mechanisms, and performance requirements of the suspension subsystem.

Aug 6, 2022 · This paper presents a model for the kinematic analysis of the rocker-bogie suspension system for six-wheeled rovers approaching an obstacle. The model considers the geometry of the suspension elements, the soil profile and the wheel-terrain contact points to define the load distribution and the stability of the rover.
The rover's rocker-bogie suspension enables the rover to drive over obstacles (such as rocks) or through depressions as large as the rover's wheel (20.7 inches, or 52.5 centimeters). Each wheel has an aggressive tread with 48 grousers (or cleats), machined into its surface.
