Robotics Monday: NXT using an Etch-A-Sketch

Name of Model: EtchBot
Created by: IndyWin

This past week, much attention has been paid to the winner and runners up of the NXTLOG 2000th entry contest (scroll down and you can read about it, at least as of this writing). Now, that winning entry was pretty clever with it's ball-as-caster trick and automated disk shooter, but I thought that this runner-up that can draw on an Etch-A-Sketch is just a bit more interesting. From what's available for documentation, it sounds like there haven't been any cool programs written for this bot, but it wouldn't be too hard to make some, I figure. It looks like the wheels that connect the motors to the dials are the only parts that included in the standard NXT kit, so you could probably reproduce this 'bot if you'd like (you do have an NXT kit, right?) Obviously, the mini Etch-A-Sketch is a non-LEGO part, but that's not really cheating because you can't operate an Etch-A-Sketch without an Etch-A-Sketch.

Oh, and if you do make a robot similar to this one and can get it to draw something fairly detailed, I'd love to see a video of it.
