The Rocker-Bogie suspension system from last year remains relatively the same from last year. This system allows for better maneuverability both during motion and in place. One design characteristic that was important is that each side of the suspension can be placed on the other side without alteration. This allows for less extra parts to be made since only one set can replace any broken piece on either side.
Stepper motors mounted above the outside four wheels will allow the rover to turn. The central wheels are pinned in place to prevent rotation. In the future, pending on funding and time, the middle wheels will also have stepper motors, allowing for maximum maneuverability.
All six wheels are independently driven. This allows for maximum traction and also allows for the wheel motors to be slightly smaller, saving weight of the overall design.
The wheels this year are also made in house. This allows for weight savings as well as making the wheels very customizable in terms of traction and mounting. They are made of 1/8" wall thickness 8" diameter aluminum tubing. Spokes are welded on the inside of the wheel to provide stability.
