The ArduPilot Project

The ArduPilot project is a family of open source autopilots based on the Arduino open source computing platform. It consists of a choice of ArduPilot Mega (APM) electronics and a range of free software versions for different vehicles.

APM 2.5 [ http://store.diydrones.com/APM_2_5_Assembled_p/br-apmpwrkt.htm ] is a pro-quality IMU autopilot based on the Arduino Mega platform, which can turn any RC vehicle into a fully autonomous Unmanned Aerial (or Ground) Vehicle. Depending on which software you choose, it can fly fixed-wing aircraft [ http://code.google.com/p/ardupilot-mega/wiki/home?tm=6 ], multicopters [ http://code.google.com/p/arducopter/wiki/ArduCopter?tm=6 ], helicopters [ http://code.google.com/p/arducopter/wiki/ArduCopter_TradHeli ], and control ground rovers and boats [ http://code.google.com/p/ardurover/wiki/Overview?ts=1341139641&updated=Overview ]. It handles both autonomous stabilization and GPS navigation and allows fully scripted waypoint missions and camera control. It supports 8 RC channels, has four serial ports and features an all-in design.

You can buy APM 2.5 for $179 here [ http://store.diydrones.com/APM_2_5_Assembled_p/br-apmpwrkt.htm ]. Everything else you need for a complete autopilot (flight software and desktop utility software) is free!

-----------

Features include:

Free open source firmware supports planes, multicopters (quads, hex, oct, etc), helicopters and ground rovers!
Simple setup process and firmware loading via a point-and-click utility. No programming required! (But if you do want to fiddle with the code, you can with the easiest embedded programming toolkit available: Arduino)
Full mission scripting with point-and-click desktop utilities
Can support hundreds of 3D waypoints
Two-way telemetry and in-flight command using the powerful MAVLink protocol
Choice of free Ground Stations, including the state-of-the-art Mission Planner which includes mission planning, in-air parameter setting, on-board video display, voice synthesis, and full datalogging with replay.
Autonomous takeoff, landing and special action commands such as video and camera controls
Supports full "hardware-in-the-loop" simulation with Xplane and Flight Gear

Hardware includes the following:

3-axis gyros
3-axis accelerometers
3-axis magnetometer
Barometric pressure sensor for altitude
5 or 10Hz GPS module
4 Mb of onboard datalogging memory. Missions are automatically datalogged and can be exported to KML
Built-in hardware failsafe processor, can return-to-launch on radio loss.
(Optional) Airspeed sensor
(Optional) Current sensor
(Optional) 2-way telemetry
