I just wanted to share with you a fully autonomous drone I built some time back for my degree in electornic engineering. It was a time when there were no fully autonomous drones, as the needed hardware was still too heavy to be flown piggyback all around your backyard. Still, I managed to pack everything I needed on top of a commercial RTF-Y6 hexacopter, including an RGD-D camera and an ARM computer.
If you feel like, take a look at the corresponding paper published during the 23th Mediterranean Conference on Control and Automation, 2015. Also, don't miss the video after the break.
