all the mars rovers have six wheels and use a rocker-bogie
system to drive smoothly over bumpy ground. the rocker-bogies are easy to see in pictures of the rovers (see pictures below). there is one rocker-bogie assembly on each side of the rover. the rocker is the larger link that connects to the rover body (the chassis) in the middle (at the rocker pivot), has a wheel on the front, and connects to the bogie in the back. the bogie is the smaller link that connects to the rocker in the middle (at the bogie pivot), and has wheels at both ends. each of the six wheels has its own motor.
