I think the flex tube is a good idea. I would use the 4x4 round brick with holes (peeron part #6222) spaced on an axle to make build the supporting framework. Attach some Angle connector #1 (peeron part 32013) to the holes on the circumference of (...) (19 years ago, 6-Dec-06, to lugnet.org.ca.rtltoronto, lugnet.robotics)

I saw the Tyco "Terrain Twister" (URL) on TV and was intrigued by the drive mechanism. It looks like it uses two counter-rotating screws/augers to move it forward on bad surfaces like sand or snow. I found a couple other references on the web: The (...) (19 years ago, 6-Dec-06, to lugnet.org.ca.rtltoronto, lugnet.robotics)

Thanks for the link. As for which programming language to learn, I'm sure C (or C related) is a perfect choice. For one, as you say NQC is C based. Secondly, learning C should give me a better insight in some of the things that happen in my Linux (...) (19 years ago, 6-Dec-06, to lugnet.robotics)
