Flybrix: A crash-friendly, rebuildable drone made from Lego bricks

@chclteteacher I'm really excited about the possibilities here. I want to make a rolling cart that can be used to teach a complete drone enrichment program -- but we need to include things like a teacher's app that provides an overview of each active drone in the classroom, a charger for 30 batteries, packaging (lunchbox style?) that makes it easy to put away the drones, and of course, a lot more curriculum than we have right now. We also need to work more on "geofencing" kids into a 1x1x2m flight volume and finish up the Scratch integration. There are so many great engineering concepts that can be taught with Flybrix! Programming too -- I've started working on a guidebook at http://flybrix.com/textbook. One other thing to note is that our flightboard is basically a superset of some sensor kit products that are out there. We can include a couple of special bricks someday that let students use Flybrix for experiments that are pretty far away from drones or robotics. For example, you could put the flightboard inside of a balloon, blow it up and use the onboard barometer and thermometer to study gas laws.
