First multi-rotor (ArduCopter Quad) up and flying :)

It only took  my JDrones kit from a few days to get to Iceland. I started building it on wednesday night and it flew successfully on saturday morning!

(Apologies for the camera tilt) In this clip I am on the second 3000mAh battery and tentatively testing the altitude hold.…

3D Robotics
Meet the Developers: Max Levine

Today in Meet the Developers, please meet Max Levine, another graphic artist par excellence! You've all seen his work in the simple, stylized icons in the Mission Planner (see below), but he's also behind many of the diagrams and instructional graphics in the ArduCopter manual.


He's also working with…

Announcing the ArduCopter 3DR Pre-order

Designed in house by myself and Alan Sanchez, this new quad frame is designed to be rock solid in every way. The frame is constructed of Aluminum and fiberglass. We've made some changes to increase the amount of free space available for electronics and sensors. The legs are moved out to leave a clear field of view from…

3D Robotics
Meet the Developers: Randy Mackay

Randy is one of the key members of the ArduCopter team, and has been leading the traditional heli part of it, along with integrating optical flow sensors into the ArduCopter code (look for a product we may be offering in that space soon).


He's also a great example of the international nature of the team. If…

AR.Drone + Android + LEGO Mindstorms NXT = bliss

This project is like a smoothie of all my favorite things blended together.

An unmanned aerial vehicle (UAV) is keeping track of a ground robot that leads a flock of similar robots.  The UAV flies autonomously and uses its cameras to help the units…

Temporary glitch in ArduCopter setup. Use CLI instead (UPDATE: Fixed)

UPDATE: This has been fixed. If you load a new firmware hex from the Mission Planner, it should now be fine. Thanks for your patience and special thanks to Tridge and Michael O for Delta Team Six-like rapid response ;-)



We've accidentally introduced a bug into the latest ArduCopter code that interferes with MAVLink setup. After you load the firmware with the Mission Planner, when you go through the setup process and click on "Level" it resets the board into…

UAV projects at MAKS-2011

This blog post contains photos and small descriptions of UAV projects, presented at MAKS-2011. Mainly, teams use commercial autopilots, however some of them had very nice their own built systems.

However, the prices are sufficently high, usually starts from $30,000. I had a talk with representatives of a few…

AUVSI Conference

This week the Robotics Association at Embry-Riddle attended the Association for Unmanned Vehicle Systems International (AUVSI) North America conference in Washington D.C. We had 14 students and 6 faculty at the event.


At the conference we met Jordi Munoz, Gigio Romero and Geoffrey Barrows. They all came by our booth at the conference and we all talked for a while about DIYDrones and the Ardupilot. We are excited to continue using the Ardupilot on our Easystar aircraft which…

APM now supports Differential Ailerons

Sometimes APM development goes fast, and sometimes it goes like molasses in winter. After being asked repeatedly (over many months - sorry) I have finally gotten support for multiple aileron channels in place. You can use this if you want to set your airframe up with differential ailerons or…

ArduCopter Traditional Heli Altitude Hold



Been out testing today with my Razor600e.

Wind was Blowing around 8-10mph on the ground, you can hear it on the video.


Testing altitude hold.

I'm still having trouble with the tail control but i think i have the Altitude Hold is sorted out now.

APM at MAKS-2011

Maybe someone knows, that this week (August 16-21) in Moscow has been MAKS-2011. This is International Aviation and Space Exhibition which is held every two years and is one of the most important aviation events in Russia.

There have been a lot of different exhibits from tiny aircraft parts to even Airbus A380 and…

Folding vs. Non-Folding Prop Testing



For my next airplane I'm planning on using a folding prop to reduce damage during landings (as my motor is mounted on the nose). The folding prop looked smaller (the actual blade-moving air portion) and I was also a little concerned about the folding blades becoming unbalanced or not fully extending.


I decided to throw three different kinds of props on my motor testing tower and find out what their performance really was. I tested them for…

APM: The Universal Autopilot

I know this isn't news, but please indulge me a moment of pride in the APM dev teams. They have built the world's first "universal autopilot". The same hardware can fly all of the above--every kind of airplane, multicopter and helicopter, along with hardware-in-the-loop simulations--with one click to load new firmware in the…

New version of Mission Planner has MAVLink tuning tips

The latest version of the Mission Planner (1.0.55) has a nice little feature that you might not notice, so I thought I'd call it out. In the Configuration tab, where all the…

I can't meet Chris, but …

I visit regularly this site since January, 2011, and I was attracted by the quality of the exchanges, the blogs, Wiki, explanations etc. …

Before choosing for a platform, I visited about ten of the other community,

sometimes, more technical, or more playful, more...etc

But !

   nobody is also clear, effective and positive in the communication as DIYDrones,

Meet the Developers: Sandro Benigno

Today's Meet the Developers is Sandro Benigno, who displays the amazing range of talent we have here. I first realized the scope of his abilities when he took the APM design files and, on his own, created the photorealistic renders of them that we still use in the manual:
