Whether you decide to do a demo/compete or simply just add more functionality to the ar-drone Node.js library we welcome all of it.
If you do decide to contribute, we could really use some help creating a library that gives us the drone’s absolute position. The drone tends to drift a lot and it could be many factors, wind, floor, etc. Here is a forum post detailing some of the challenges http://www.ardrone-flyers.com/forum/viewtopic.php?f=23&t=3558
If someone wants to take on this challenge the community will LOVE you. This will give other drone developers the ability to do more complex flying routines.
Here is the issue for questions, comments and suggestions. Let us know if you are going to be working on this, so we don’t have multiple hackers working on this separately. https://github.com/nodecopter/droneolympics.com/issues/2
If you are not using Node.js that's totally fine too.
