this looks quite nice. Just before finding this thread, I was thinking about how to construct the UAV with phidgets. My idea was than rather copying ar.drone (vehicle+smartphone-iface), I wouldcreate a core - high priority code in SBC, that keeps the vehicle stable in the air and protects it from crash when battery is low. And then a second (user) layer, that can translate commands and navigate the drone around our planet. And the general communication layer could benefit from other projects (3g,?).
Very nice, anyway. And not an easy job. e.g. I have 3 usb's on sbc1 and I can observe random 'disconnects/reconnects' of the 8/8/8 part of the board. And the reading from the ultrasound sensor is not always correct. And you face many more problems...
I follow this thread. I am really interested.
finally our gimbal-mount is done and ready for testing. Check it out at http://www.robobuam.de -> Projekt Robodrohne.
