Any idea on how to implement indoor navigation around a circuit indoors?I understand that for the outdoor concept, GPS is used.What about indoor,I have colour sensing track lines but I would prefer to find an alternative as the lighting intensity would affect my calibration and thus result in a great deal of inaccuracy during my navigation.

This was one of the main challenges of the 2009 International Aerial Robotics Competition. Everyone who fielded a flying entry was doing SLAM with some kind of ranging sensor. Because our vehicle rotates, we were using relatively inexpensive Sharp IR ranging sensors. Scanning laser rangefinders were popular, though expensive. For more details, the competition papers are at the competition web site.

You can use a precise (+-2cm) Indoor "GPS": http://marvelmind.com/.
Here a couple of demos:

I can answer more questions about Embry-Riddle's competition vehicle (SamarEye); I'm the project manager and captain for that team.
Fantastic Stuff.
Very inspiring.
What concept is this using?
Cheers!
