What basic stamp module would i need to run a uav? I really dont know that capability of the modules. I know the technical specifications but not how they translate to performance. I would like to run at least 3 sonar, 3 rpm monitors, a GPS, and a tri axis accelerometer, at first. I might add more things latter. Can the BS2 run these quickly enough in the uav to maintain flight? This is my first time on the forum and would greatly appreciate some help.

    I doubt you could do it with a stamp because of the speed needed. I would recommend the Propeller chip as a starting point.

    The problem is i dont think i have enough knowledge to work with the propeller chip. Even the BS2px could not handle it? If i have to use propeller chip how much time and effort is needed to learn and how?

    How far is the other side of the sky? How high is up? What do you know already?

    Learning the Propeller and Spin is probably nowhere as difficult as you fear, but it takes time and effort. The Propeller Education Kit tutorials are downloadable and you can look through them. A lot of basic I/O code is already done and in the Propeller Object Exchange. You might look through there and download what sounds useful and look through it.

    Chaz,

    Another option might be to buy a WAM (Whats a Microcontroller) kit. These are cheap and you can learn a TON about the sorts of things needed to make a successful UAV. Then, when you have a better idea of what you need to do and how to do it, you can select which proccessor will work for what you want to do.

    what is an UAV?

    If this is an model airplane, you might need some help from a pilot assistant (thats an autopilot controled by light sold by Futaba) . this makes life easier, about timing you have plenty of time to control servos and get information , remember that have to updade them every 20ms , thats a lot o time , the real problem is to get info from a gps, with an NMEA protocol your sistem have to halt until the info is sent !

    But first things first .. what is a UAV ?

    Chaz,

    Check out the diydrones.com website. There are some BS2 autopilots described on there that might be a good starting point for you. I believe one author used a BS2p for a basic GPS waypoint navigation setup.

    Just for a little more specification, the UAV i was planning to build is made for vertical flight with ducted fans, as well as forward flight. Responding to Mike Green, I was not planning to go over 20 feet to start with, and i know electronics well and programming okay, although i have not worked with the basic stamp system before. Thanks for the help. I am looking into the ideas posted.
