AP with Ground Station and 2-way comm

I wanted to post the code and exe of the Flash file for the Ground Station and my AP. If you want to try it, you need to do a few things first.



(If you try this, remove your throttle or disconnect your ESC from your motor!)

1 - Load the DefaultsWriter.pde onto the Ardupilot HW to get some decent values into the EEprom

2 - Load the Waypoint Writer onto the Ardupilot HW to put some waypoints into the EEprom

3 - Load the… Continue

Atto in Africa


Had a very pleasant afternoon picnicking and an Atto flight in the Kamberg, take off at 6500' on a hot day.

The flying wing goes a little quicker in the thin air!

Deep joy.

I Can See My House From Up Here!





I Can See My House From Up Here!

The Northrop Grumman RQ-4 Global Hawk unmanned aerial vehicle (UAV) is quite an impressive piece of hardware. It can stay in the air for more than a day, has a range of 3,400 miles, and at very high altitude (its record is 19,928 meters (65,380.6 ft)). Usually it's the military that would… Continue

Want to test code with the simulator X-Plane?

Here's an example of how to get data from the simulator: http://gist.github.com/228998



It has everything you need to treat it as a virtual IMU. This was instrumental in getting my extended Kalman filter running (to be open sourced soonish) and I hope you find it useful too!



(I'll do an updated version that shows you how to control the plane in X-Plane from your code.)…

ArduIMU v2 Questions

I was wondering what kinda of extra instrumentation would be required to use the ArduIMU as the autopilot for an autonomous aerial vehicle. I was also interesed in the benefits of the IMU vs. the thermopile concerning takeoff and landing from water, and if the water would in some way confuse the standard Ardupilot because of the temperature of water vs. that of the ground.

THE C328 LIVES



After 3 weeks of hacking, the C328 started producing decent results. Your main problem if you intend to control it from a computer on the ground, using Xbees, is getting the UART to work reliably. It needs a real clean signal & short cables to work at 115200. Initializing it still takes several power cycles & 20 second delays. Decided 320x240 is the best compromise between resolution & frame… Continue

2.4GHz TX/RX radio module with "1000m" range (fast enough for digital vdeo?)


This would seem to be the same power profile as the RC radios - with trans capabilities.
As it is "Wireless USB", it should be fast enough for first person video in digital modes.

Razor 6DOF IMU + Arduino + DCM

I recently got SparkFun's 6 IMU board and played with it a bit. Basically I connected Arduino and Razor 6DOF board and ported DCM code. Code is ArduIMU v13 but just made to work with Razor board. I am not sure what to think about gyros on that board as it takes them a while to "warm-up". Below you can see run from cold start for over an hour and "zoom' on first minute or so (just raw ADC values). On the link referenced above, you… Continue
