 | | Copy the Tyco "terrain Twister" screw drive?

|
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)
