DelFly II follows a white line only using his onboard camera. The width of the paper gives info about the height of the DelFly. The orientation of the paper gives the flying direction.
This algorithm was used with success during the EMAV 2008 indoor competition, winning a prize for being the first MAV to ever compete in that competition autonomously.
Very cool. keep up the good work :D
