How To Autonomous an UAV via gps ?

Hi Darken Hero,

The concept is simple, the devil is in the details.

Ideally, you have a UAV that an establish where it is, using GPS or other navigation aids and then orient itself to move to the next waypoint.

As long as the UAV has an unimpeded path, it is a simple matter of maintaining a movement vector to the next point, recognize that you are at that point and then changing your orientation to begin moving to the next point.

The math is simple, the control logic is simple, but maintaining the vehicle safely against things in the environment that could cause it problems is where the problems occur.

Remotely piloted vehicles rely on onboard instruments and forward looking video to provide the operator with information about the current situation around the vehicle so that the operator has plenty of time to avoid problems.

For fully autonomous vehicles, you need to create that onboard situation awareness with sufficient options to avoid catastrophic events.  Good luck with that one.

In a closed course, it is fairly easy to establish safe movement corridors between the way points to safely move the vehicle.

So depending upon what type of vehicle you want to use and the geography in which you want to use it in.

Thanks DAB for you reply ^_^

so i got my raspberry pi , i should get a GPS .. how to set up a fixed route practically  ? 

another question , can i do all the way process with raspberry pi only with GPS or i need an Ardupilot for control and navigation ?

Sorry am a real noob

Based on the questions you're asking, I can estimate your "level of expertise" with regard to "raspberry pi" as well as "RC model flying". My analysis says: This project is too ambitious for you.

Your project sounds like a challenging project for a group of 5-10 university level electrical and mechanical engineering students..

Hope you are not offending Roger,

a though arose in my mind reading the request of boombo and thinking to all the difficulties he was "searching" by himself. Without forgetting the very good posts on the UAV issues explained and partially solved by screamingtiger during the SciFi Your PI challenge and beyond. I though to one of my preferred citations, that is also my motto: Ció che é pensato esiste (what is though exists) by J.L.Borges ...

If I was always doing only what was just at my level of expertise (I am not an engineer, but - maybe - a literate instead a philosopher, poet and story-teller, chemistry) I was always asking myself how to power my first AIM65, bought in 1979

Cheers. Enrico
