Hi everyone,

I'm working on an autonomous helicopter project - we have a Bergen Industrial Twin (http://www.bergenrc.com/Twin.php) as the platform.

My initial plan was to have some of my guys develop a flight control system using data from an IMU and GPS and run on a small Linux board (e.g. Gumstix). This would then connect to a microcontroller for servo control, as well as to the higher-level onboard control PC (an XP-running Via Nano-ITX board) that does image processing and other tasks.

But because of time constraints, I'm thinking of instead just finding a sort of off-the-shelf solution for flight control. I saw the autopilot (http://autopilot.sourceforge.net) project, but does anyone know if it actually works (the site is a bit ambiguous)? I'm going to take a look at Vicacopter (http://vicacopter.com/index.php), but it seems to only be able to hover at this point?

Rotomotion has its flight controller (http://www.rotomotion.com/prd_UAV_CTLR.html), but it's a tad pricey ($6,000+) and more significantly, seems to be an all-encompassing and closed system with waypoint calculations, base-station link, servo controller, base station software, etc. all built in (which I don't need - my own software will be doing that).

Basically what I need is a unit/software that the onboard PC can control (e.g. so it can just set the direction, speed, etc. and have the flight controller do what's necessary).

Any ideas?

Anything less than a fully integrated & calibrated system is going to be a lot of work & risky but success rates seem higher with bigger airframes. There's also Carvec, Neural Robotics, Micropilot, & Adaptive Flight. Heard bad news on Micropilot. Success may depend on having a DGPS base station or close proximity to a WAAS station, but no-one's talking about it.

Would this count as a tricopter or as three UAV helis ? Cool, whatever: Lifting several kg weight tied 13 meters below three UAV helis
