The back wheels are large and have small ridges to grip onto surfaces, while the front wheels also have ridges but are smaller. This way the rover will be tilted, causing the camera to face the floor(for images). The front wheels can also be removed and replaced with larger wheels so the camera is able to face in front of it. The rover camera can rotate to look in all directions and is held by a camera stand. The camera stand sits on an adjustable holder on the rover body. It is able to slide back and forth on the body and can also be locked in place. Multiple cameras/camera stands can be locked onto the rover body.
