Oxygen-breathing weaklings

Noting my comment in the NYT about humans being the "weak link in the chain", Sebastian Thrun (winner of DARPA robot road race and designers of Google's autonomous cars), reminded me of this classic from The Onion. Brilliantly… Continue

Transformer bot turns from rover to heli

From IEEE Spectrum:

Designing a robot that can traverse variable terrain usually involves a number of unsatisfactory compromises. You can go with a flying robot, which will almost never get…

Sparkfun Autonomous Vehicle Competition recap video

Great fun. The Sparkfun team did a terrific job of giving a flavor of this competition, from the thrill of victory to the agony of defeat, and all the crazy crashes inbetween.


It's full of DIY Drones team members, too, with Doug and Jason highlighted. Lots of great shots of Doug's catapult. The post is…

Successful flight of the MAJA Drone with the ArduPilotMega

Successful flight of the MAJA Drone with the ArduPilotMega

The MAJA Drone built and tested by Jean-Louis Naudin, a true UAV with full autonomous flight capabilities done on May 2011.


Avionic setup:

 - Ardupilot Mega (Atmega 1280 @16 MHz), 32 Mips

 - Full 9DOF IMU,

 - Built-in 16 MB Data Logger,

 - Airspeed and absolute pressure sensors (Bosh),

 - triple axis magnetometer HMC5843,

 - 10Hz…

Mode Switch Setup for Turnigy 9x with ER9x Firmware

How to setup the mode switch mixing for Turnigy 9x with ER9x

First thanks to Olivier whose post in my Futaba tute  helped me get my head around ER9x mixing.

I am an AC2 user so there may be some APM differences I have missed.

This tutorial was created using eePe v247 and ER9x r349.

I am…

AttoPilot flight using HK GCS

I love to see my GCS in action. The exciting stuff (for me anyhow) starts at 2:30. Great video (as always) Max!

DIY Drones in the New York Times!

Very cool: The New York Times was at the Sparkfun competition and did a story on DIY Drones!

Latest AC2 update

This is to let you know that AC2 beta has been updated based on everyone's feedback. I think we're getting closer to a full release.

Things to concentrate on:

Logging - Logs are the most helpful thing you can post. If you have an issue, please post the log and let me know where to look.

Altitude hold: The Dterm was a bit too aggressive preventing the copter from changing altitudes. It's been lowered by default to 0.03. If you have trouble…

DroneCell and 900Mhz Xbee problems ?....


I had the brilliant idea of building a device that will send GPS location over SMS text messages.

this, after i lost my prototype quad Arducopter last week. it felt not too far, i could hear it, but a few days of searching in the forest gave nothing....


R.I.P. dear copter.

here is the last successful flight, in memory..

Flytron's OpenLRS available now

OpenLRS is a radio control system designed by Flytron in Turkey. For most of us, the name will make clear that this is an open source product. Source code is available for download, you can make improvements or change the code and share these with others.


The OpenLRS M1 is an open source transmitter module that is configurable for any channel (420-450mhz) or any…

TaigaCam and pitch/roll stabilizer

Now camera has pitch and roll stabilizer. In some shots camera looks plane. Camera can tilt 90 degrees to one direction and 45 to other, you can see the limits in sharp turns. It was windy day, 4 - 8 m/s or 14 - 29 km/h or 8 - 16 knots.


Program codes are in…

Double blade disaster



Flew something for the 1st time since the PCS order. She didn't

oscillate, but didn't have enough power.  That design had no coning

angle.  Back to wing designs.

TaigaCam and camera stabilizer, pan test

TaigaCam and Ardupilot tries to look home position all the time. Camera can turn about 100 degrees. In Ardupilot there is no compass, and therefore it calculates flight direction once per second according to gps. That's why camera turns slowly.

This pan-system needs only one line of code to Ardupilot. In plane…

UAV School Project

Here is a quick vid of my final project I'm building in electrical engineering. It's a tricopter UAV with thrust vectoring. As of now I have implemented roll, pitch stabilization, yaw and height are controlled by the aircraft. I just control the x and y movement.

All the control algorithms use fuzzy logic. Why? To be different... and to overcome…

Mode Switch Setup


How to setup the mode switch for APM/AC2

This tutorial was created using the Futaba 12fg, but keep reading and it may give you some ideas on your radio. If you already have your particular radio figured out, write a tute like this and maybe we can get a collection of them added to the APM/AC2 wiki's.

You will need two spare switches, a 2 position and a 3 position to be able to get all six flight modes for the APM/AC2. We are aiming to get pulse widths of 1165,…

Aluminium Arducopter parts - first attempt!

As part of my plane to create a simple, solid Arducopter frame, I have had a number of parts laser cut in 2mm 6082 aluminium from the original Arducopter frame design by the DIYD team.



The parts have come back a little more "bashed up" than I expected, but apparently that's normal, they just…
