The wheel design uses a mindsensor bracket to house a continous servo turning a Lego off roader wheel. This sits under a turntable which will turn using a medium PF motor. This was the last wheel so all I have to do is attach to the Rocker-bogie!

My Rover Wheel Design
Whilst finishing off a new wheel design for my rover I thought I'd grab a quick pic and post.

Hitec Continuous Servo
When deciding how to move my rover i had to decide what with? Large PF motors or an alternative. I made the decision to go for a continuous servo because of several advantages over other types of motor:- 
- NXT Servo supports 8 servos (6 x wheel, 2 x tbc)
- NXT Servo could be powered by a battery / solar charger
- Servos include rotation sensor for precision control
Mindsensors don't (as of yet) sell a continuous servo so I had to buy from Active Robots. They did however deliver a prototype mounting kit which fitted perfectly.
These will provide the movement and accuracy I need for my rover - Model purchased Hitec HSR-1422CR.
