EDIT: Update: video here
Well, i desided to MOD a Sandcrawler. I basicly just stuck a couple of motor's in it.
From the outside you can't even tell!
These two pics basicly show the (very basic) mechanisim.
It's fairly simple. But it works great! It took me about an hour or so. And after a few tries i had it working great!
Over-all, i'm quite pleased with it.
Let me know what you think. All Questions / comments / constructive critisims welcome
