After investing most time into PX4 for quite a long time now, the PX4 native stack has made it into a shape where we can fly fixed wing in autonomous mode with it, and there is also progress on multicopters. This put QGroundControl back into the development focus, since the field tests…

3D Robotics is one of the five manufacturing companies in CNBC's Disrupter50 list; along with Makerbot, Quirky, Shapeways, and Rethink Robotics.

In 1927, Doolittle was the first person to successfully execute an outside loop — previously thought to be a fatal maneuver. Carried out in a Curtiss fighter at Wright Field in Ohio, Doolittle executed the dive from 10,000 feet, reached 280 miles per hour,…

Here is my connection (You can check GPIO pinout here):

I used theFTDI GPS adapter cable, solder pads can be used also, just have…

The key…

First test of targeting system. All calculations are done in the air.

Camera provides two streams. Highly compressed (rigth window) and detailed (left).

3 axis BL gimbal. In low light conditions and excessive vibration.

John modified a point-and-shoot camera to capture near infrared images. This is half the puzzle in building NDVI images for analyzing crop health.

Information on the conversion can be found here: …

A couple months ago I was testing ArduPlane and some of the different modes. I was not getting on very well in FBW-B* mode. If you look at the image below. You will see the purple track. I was loosing altitude and I couldn't understand why. You can see just before the path goes red, I'd lost a lot of…

Nicknamed "Laurel and Hardy", for reasons that should be obvious.

Everything calibrated...time to get the PID's done! Well..once it stops raining and snowing here in Switzerland. :-(

Some build annoyances, which I'll go into in an additional post.

Laurels bits…

Another cool Kickstarter project. It looks like it works well on the ground, the video doesn't show very much of the flight performance. It does appear to be quite robust at least. Thanks to…

Because the latter one of condor drone tests went very well in the navigation, I decided to mount the camera aboard the condor photography for mapping and the results appear promising.

Dear Friends,

on VirtualRobotix we are working in new advanced platform based on GolaKele Frame and VR Brain Gold and PRO configuration.

This is first example of service where we use the our multicopter for roof inspection.

In the test use also Wookong DJI on other Hexa for doing some comparison on two different kind of…

Several months ago I started working on a system called Afterflight to organize and browse my tlogs and dataflash logs, sync them with video, and view them along with a map GPS display. It still has a long way to go, but there is a fair amount of working functionality so I figured I'd get it out there…

Here is a short video of the design, build and crash testing of the Game of Drone's Battle Quad.  It's waterproof, bulletproof, and can fly away from almost any crash.

CNN just posted this story

Here's an excerpt:…

I had a couple of requests for a still shot of the 12-rotor beast that Joe and Justin cooked up, so here it…

This might be a common knowledge, but in the last months I haven't seen a similar post. Maybe someone new to barometers might be interested in this data.

The GPS receivers return altitude data, but this is inaccurate. The error margin depends on the satellite constellation geometry…

Last Wednesday I went out to the field for some flight tests and gains trimming. Other people where flying their model planes there too. We usually follow a counter-clockwise pattern while flying to avoid collisions. That day I was flying especially slow, so when I took the turn, I did so on the spot and…
