I report some pic about my idea

My scope is to build a platform to put in different craft (airplane,
hely, boat)
able to drive them all, focusing just on the algorithms to be used.
At the while there are many different project (i quote some open source
like ArduPilot (http://diydrones.com) and Paparazzi
(http://paparazzi.enac.fr/wiki/Main_Page), they use something IMU
and others times thermopile...
But all this projects use little microcontroller (pic...avr or like).
The freerunner is really near to be a proper hardware system for UAV.

With the navigation board v3, we had the gyro, the compass and some
other stuff through i2c, if there aren't issue about the bottleneck
among cpu and gyro (the main sensor in an IMU, event more important than
the accelerometer) the hardware has enough sensors to
I built a little board with a pic18f4550 (usb) that allow to choose
between the remote controller and the freerunner, in this way it's
possible to develop the software in a safe way. (if someone wants some
other information just ask)
This chose is really bad, in my opinion, usb is not enough realtime...in
the future, i'll rewrite the firmware to control it through the spi of
Another thing that i'll study in future is how put a xbee module
connected to the
freerunner to the 3rd serial port.

I'm following what in others project has done and works with the
unnmanned craft,
so these are my firsts steps.

There are really much to explain...(and much more that i need to
understand! ;)
if someone wants more info just ask, i'll be pleased to tell you all i
know about this

Thanks :)

Sure, we'll meet soon.
