Intro:
As most of you know, we are running a fundraiser to help cover costs for developing LMRv4. Visit our Donation Page for more info.
Anyone who makes a donation before June 15, 2012 will be entered into a drawing to win one of five prizes generously donated by Adafruit!

We need another cool robot to pick the winners. Sure, we could use Nils’ machine or RobotFreak’s robot, but where’s the fun in that?
So here is your challenge.
The robot must be able to make random selections from a pool of names. There are five prizes, and just in case we want to pull 5 alternate winners. So we need 10 names picked.
The rules for the drawing will be that the first name picked gets their choice of the prizes, the second name picked gets their choice of the remaining, etc. So the robot challenge must be able to support that.
The drawing will be made live after the challenge deadline. The drawing will also be recorded for posterity.
Rules:
- The challenger must set up a system that can pick a list of 10 numbers representing our donors. The list of names will probably be on the order of a few hundred.
- The system must provide a way to determine the order in which the names were picked.
- The system must be fair. (This may seem easy but it is hard to create a physical random number generator with a uniform distribution.)
- The system must use an autonomous robot as part of the process of picking a name. E.g., if a dice is used, a robot must throw the dice, or read the dice, or BE the dice :).
- The system must be as transparent as possible. E.g… A robot printing out a name on a lcd is not very transparent unless you can show how the code works step by step as the choice is made.
OK. Get those thinkers thinking and make it happen! To be considered, you will need to post a link to a video as a comment to this challenge page. The video must show that your robot can meet the requirements in the rules above.
The winner will be selected by Nils and myself.
