Hey guys,
I visited a motion capture studio to get the control side of things working for my (hopefully one day finished) visual odometry (ego motion blabla) program.

I couldnt help myself:

Thanks!

Here is a much better video of the same thing, with some first person footage half way through: http://www.youtube.com/watch?v=WPi__Q6CNdQ

Some info:
I use an external tracking system (Qualisys) on a windows computer, and access it via the network from my laptop running ubuntu. Everything gets exposed to ROS; where I have a custom client and joy stick driver. ROS provides all the tools to visualise everything in 3d and plot all the incoming/outgoing signals. A PD controller is used to convert distances in the xy plane to roll/pitch angles, a PID controller is used to control the thrust, and a P controller for the yaw velocity. The tracking system runs at 100hz and less aggressive maneuvers also work around 30hz with 100ms lag. So there is hope for using a camera/kinect system for tracking.
