Curiosity mobility system, labeled
Curiosity's wheels are supported by a "rocker-bogie suspension system." Each side has two arms (a rocker and a bogie) that can pivot, connected to each other through a differential bar and pivot on top of the rover. When one rocker tilts in one direction, the linkage through the differential causes the other rocker to tilt in the opposite director, keeping the rover body relatively level even when the wheels are climbing large obstacles.
