This video shows some recent flight test results from my PhD research on autonomous UAV docking, that was conducted with the Australian Centre for Field Robotics (ACFR) at The University of Sydney. To the best of our knowledge, these experiments are the first time two UAVs have docked in mid-air.

Some of my other videos provide more specifics on the hardware/software, but I'm using my own autopilot, a Beaglebone Black as the formation flight computer and an Odroid U3 to do the onboard vision processing. All the guidance, navigation and control algorithms on all the hardware is developed in Simulink and automatically converted to C/C++.

The IR vision aspect is probably of interest to some of the guys doing auto-landing with IR beacons. We use a C920 with narrow bandpass filter and 940nm LED markers without modulation. It works in all lighting conditions except when looking directly at the sun where the high number of false positives are difficult to distinguish from the actual markers, but there are a number of ways to handle this infrequent situation.

There are some nice airborne shots so watch in HD!
