[Highschool - Engineering & Robotics] Axes (ATVs)

[tha Guardians]

Okay, so I'm trying to find an maneuverable ATV design that's simple and doesn't use more than 4 wheels. I think the basic four-wheeler design will be the best and most efficient idea for my project.

My question is, what kind of wheel and axel system should I use, and how should I construct it?

I already have my ATV robot running forwards and backwards. It can do wide turns and point turns by increasing and decreasing the output of the motors. What I want to do is make the wheels themselves turn, to make it more useful in an obstacle course or outdoor environment.

I'm using the Mindstorm's LEGO NXT kit if that helps.


Edit: Wow... you suck, FFRers -_-'

idk if you still need this, but i threw together a quick pic of what I think you want:

you would attach a servo to the big circle in the center, and when it turns both wheels turn. I have no idea how to implement this with lego.

OMG! NXT'S RULE!
I have one myself. Although I currently have mine in the shape of a penguin that actually waddles, eats, poops, and has controllable flippers. Took 13 hours, 2 NXT kits, and 2 friends.

This won't work, but it just gave me a great idea =)

Thanks a lot.
