ArduPilot - Arduino Compatible UAV Controller w/ ATMega328
ArduPilot is a fully programmable autopilot that requires a GPS module and infrared XY and Z sensors to create a functioning Unmanned Aerial Vehicle (UAV). The autopilot handles both stabilization and navigation, eliminating the need for a separate stabilization system. It also supports a "fly-by-wire" mode that can stabilize an aircraft when flying manually under RC control, making it easier and safer to fly. The hardware and software are all open source. The board comes with all the surface-mount parts already soldered, but requires the user to solder on connectors. Firmware is already loaded, but the autopilot software must be downloaded and loaded onto the board by the user. It can be programmed with the Arduino IDE. All details and instructions can be found at the project's home page.
ArduPilot features :
1、Built-in hardware failsafe that uses a separate circuit (multiplexer chip and ATTiny processor) to transfer control from the RC system to the autopilot and back again.
2、Altitude hold using throttle or elevator and GPS altitude data
3、Includes ability to reboot the main processor in mid-flight.
4、Multiple 3D waypoints (number only limited by memory; currently can support at least 200)
5、Comes with a 6-pin GPS connector for the 1hz EM406 GPS module. Faster 5hz GPS modules, such as the uBlox 5 series, are supported via an optional 3.3v daughterboard.
6、Has six spare analog inputs (with ADC on each) and six spare digital input/outputs to add additional sensors
7、Supports addition of wireless downlink module for telemetry.
8、Based on a 16MhZ Atmega328 processor. Total onboard processing power aprox 24 MIPS.
9、Very small: 30mm x 47mm
10、Can be powered by either the RC receiver or a separate battery
11、Has an efficient ASCII NMEA parser for compatibility with standard GPS modules at any baud speed.
12、Hardware-driven servo control (using the Arduino Servo Timer library), which means less processor overhead, tighter response and no jitters.
13、Four RC-in channels (plus the autopilot on/off channel) can be processed by the autopilot.
14、Status LEDs for power, failsafe (on/off) and GPS (satellite lock).
ArduPilot Dimensions : 30mm x 47mm
