Yeah, it's definitely worth it. All you have to add to a proper Mindstorms kit is the PVC pipe for the bar (one 10-foot length, two tees, four elbows), some poster board to add a black line below the bar (though perhaps the sensor mat could be used here), and some dental floss (we use mint waxed). It took me five hours to build a proof-of-concept; the kids were hanging at the end of five 70-minute sessions plus a smidgen of extra time.

To pin these on me wouldn't be right. Sure, I showed them better living through worm gears and all, but they've got good instincts. Look for them on an FRC team near you spread over the next, oh, seven years or so.
