- Provides more traction for climbing obstacles, therefore reducing the amount of slippage
- The extra wheels reduce the normal force on each wheel by 1/6 the weight of the rover
- Has an advantage at turning, since it has a pair of middle wheels close to the rover's pivot point
- Even better if it's closer to the rover's centre of mass?
- Allows for a lower centre of gravity
| - Provides more traction, therefore experiences more turning resistance (cleaner turns)
- Requires more actuators, suspension → overall, more complex and heavy
