Additionally, it's unclear what license the IFI default code is under, so you cannot just assume that it's safe to distribute that either. It would be a good question to ask IFI in their forums.
Also, in your README file you state this:
Quote:

Team 1676 has decided to release is source code to its robot in order to help other teams programming theirs or for any one else interested. It is released under the terms of the GPL so you are welcome to modify and use this under your own robot but you must release the source code on your teams page and give us credit. As well as Kevin Watson for writing the original code.

(Emphasis mine)
This is not how the GPL works: if another team uses your GPLed code in their robot, the only time they would be responsible for releasing the code and any changes they made is if they were to distribute the compiled binary. If they keep it to themselves and only running on their robot, they do not have any obligation to release the code. See
this for further information.
