Ralph is the creator of the pbForth environment for Mindstorms and recently presented at the MIT Mindfest. Floor dragging, wheel sorter, Small Technic tire based drive. His small, compact robot was nimble and his wheel sorter was really quite original-it rotates out unless a marble is the right colour, when it rotates in to keep. A side profile shot of robot13. Kudos to Iain for stenciling a very cool name on the side of his bot.
Small bots move nicely on video.
Chris Magno's bot, RAMP, is just on the side of this photo. MC2 on the mat and in the corner. Another picture of Jin and his robot design. MC2 used a multistage combine which rotates a set of rakes synchronously to pull marbles up into it's stomach. And of course, Jin put in special touches like face-like features, a rotating radar dish and great styling.
