Welcome!
This is a site for all things about amateur Unmanned Aerial Vehicles (UAVs): How-to's, videos, discussion and more. You can read more about us here. Sign up and post your own articles and discussion topics!These are our Arduino-based open source autopilot projects:
* ArduPilot, a very low-cost ($24.95!) autopilot with great expansion capabilities
* BlimpDuino, an autonomous blimp with both infrared and ultrasonic guidance
Other UAV/autopilot projects and code, by processor and OS type, are here.
Earlier DIY Drones projects, including Lego and cellphone autopilots, are here
Interviews with interesting UAV and autopilot experts are here.
FAQs:
* I'm new to all this--where do I start?
* Are amateur UAVs legal?
* What's the difference between a gyro and an accelerometer? Do I need both?
* I'm confused by all these terms! Is there a glossary? (yes!)
You can find a list of external UAV resources, including commercial UAVs and other open source UAV projects and code here.

For those that missed, it, today's Sparkfun event was a smash, literally and figuratively. It turns out that U(A)V's of all stripes have the same propensities as Charlie Brown kite. Aside from the Trees into which Jordi scored direct hits, the wheeled varietals made their own attempts to climb… Continue

Tilt Error Compensation
First of all I many thanks to Chris for directing me to the right link, which has enabled me to have an enormous understanding to what I needed to do and gained other info that I was not aware of...Brilliant Forum!!!
Right now I am working on the CMPS03 digital compass. I have managed to get the compass programmed and it works fine on the Horizontal/Yaw manoeuvre. I am working on the till error compensation right now (Pitch & Roll). However, I am struggling with the following areas:… Continue

Failures and Sucesses
Having messed around with RC craft for the last 20 years or so and having built and flown all kinds of 'craft' from 1/4 scale to 28g (1oz) planes - heli's, boats and cars too, I thought the ArduPilot project seemed a interesting new avenue to try.
Started on my AP (ArduPilot) project with the arrival of my Arduino168 board, wasn't sure I wanted to commit a plane yet so tried it in an RC car. ArduPilot board /EM406 GPS, v1.0 software, RTL set to 1, code u… Continue

IMU alignment code progress
Brian is busy making it talk to the Arduino board. Meanwhile, I have been working on the alignment code. The alignment proccess uses the IMU's sensors to determine its orientation (roll, pitch, and heading) while stationary. I spent the last few days writing code based upon this document. Sorry, it's not… Continue

Two funerals in one weekend :-(
Yes I was so proud. I had a perfect working ardupilot. I was going to attach my just arrived Z sensor.
Then Murphy law kicked in. When a friend was over I showed him my ardupilot. and the working.
The positive power line of the lipo accu was not perfectly isolated and made contact with the back plane of the ardupilot.
Yes it fried it. :-( . No swet I have a spare one). Solderd the headers tested the upload all fine. Now I needed to load the new firmware f… Continue

A "realistic" UAV flight dynamic model of a popular UAV airframe
- How to create a "realistic" UAV flight dynamic model of a popular UAV airframe (such as Mutiplex EasyStar ) for simulation?
- Is it possible to create a generic model such a way that the model can later be re-configured for different UAV airframes?
The model should be able to accurately approximate the next state (position, a… Continue
