    Roberto, do you have some pictures/videos of your application for ar.drone?

    From the  AR Manual:

     

    Domestic animals 

    Avoid using the AR.Drone around domestic animals, particularly pet dogs. The AR.Drone incorporates an 

    ultrasound altimeter  (emission frequency:  40kHz).  Ultrasonic waves are known to disturb certain 

    domestic animals, most especially dogs. Using the AR.Drone in the company of a dog may lead to it 

    behaving erratically or perhaps even dangerously.

     

    The last of many good warning & caution statements:

    Maybe we should include a similar warnings page as many new bees  will not be fully aware of all potential DIY Drone hazards.

     

    Might save a finger, prevent a fire, or calm down a pissed off dog.

    Nice :)

    I developed some usefull application on Ar.Drone. I put on it also some ROS application . Have a linux board onboard is a big improvment.

    In my last test i saw that the serial port was available in operating system. I devloped a firmware to directly interface PPM SUM recived and control the quad for my friend.

     

    Best

    Here are some detailsof an autonomous hack from the Delft University team:

     

    "First GPS flight with the ARdrone from parrot.

    We used our SmartUAV software (developed at the MAVlab of the university of Delft the nederlands) and compiled it for the linux on the ARdrone with arm-2010.09-50-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.tar 
    SmarUAV runs on the drone, it handles the autonomous flight by sending AT commands on the UDP port. 

    The way we do is basic: we give a constant forward speed, height is done by the ardrone and the yaw is done autonomous so the drone fly on the flightpath. (first test, proof of concept)
    The flightplan is made on the ground station of Smaruav and uploaded on the drone by wifi.
    Thanks To MAPSGPS http://www.ardrone-flyers.com/forum/...7bffd&start=45
    all the navdata and GPS data is received in SmatUAV on the drone, autonomous navigation is done one board!
    Also on the ground station navdata and GPS data is received (by wifi) to check status of all the components and see the flight path.

    The gps we use is a ublox which give serial data. Connecting this to the drone will stop the motors during flight.
    Solution was a FTDI chip on the GPS and then connect it to the drone USB port. NOSAARI FTDI driver have to be running on the drone.http://www.rcgroups.com/forums/showthread.php?t=1401935

    I`m not able to release SmartUAV (it is not opensource) but I can release all the other thing I did.
    This is the code I have during booting the drone:
    It gives 5v to the USB port and have a FTDI and USB driver. Also it sends Navdata to a rooter so a other application can listen to it. MANNY THANKS TO MAPGPS and NOSARI"
