Answer:
rocker bogie which is a sattelite Defence mechanism
Explanation:
NASA recently started an ambitious exploration program of Mars. Pathfinder is the first over explorer in this
program. Future rovers will need to travel several kilometers over periods of months and manipulate rock
and soil samples.
The term “rocker” describes the rocking aspect of the larger links present each side of the suspension system
and balance the bogie as these rockers are connected to each other and the vehicle chassis through a
modified differential.
In the system, “bogie” refers to the conjoining links that have a drive wheel attached at each end. Bogies
were commonly used to bare loading as tracks of army tanks as idlers distributing the load over the terrain.
Bogies were also quite commonly used on the trailers of semitrailer trucks as that very time the trucks will
have to carry much heavier load.[1]

As accordance with the motion to maintain centre of gravity of entire vehicle, when one rocker moves upward, the other goes down. The chassis plays vital role to maintain the average pitch angle of both rockers
by allowing both rockers to move as per the situation.[4]
The physics of these rovers is quite complex. To design and control these analytical models of how the rover
interacts with its environment are essential. Models are also needed for rover action planning.
