Frame design.

I've been experimenting with frame design, an essential component to keep all the parts flying in formation.

I printed some interlocking plastic parts in 2mm PLA & super glued them together to see how rigid/strong the end result.

The attached pic shows about half the…

Robotized Radiation Mapping

Dear community members,

This is very preliminary work on aerial robotic radiation detection in real-time and in a GPS-denied manner. The robot localizes based on visual-inertial data and integrates a deferentially installed 2-radiation detectors solution to exploit their polarity characteristics. Most of the research is ahead but we…

Skyhunter Pixhawk 3.7.1 parameters and configuration

After a great deal of difficulty and trial/error I have finally got my skyhunter setup and working with the pixhawk running ardupilot 3.7.1.

The most difficult part was the configuration of the servos being that this fixed wing plane has two aileron servos, an elevator servo and no rudder. The way I resolved this was to setup the ailerons as evevons (Elevon_Output); connect the right aileron servo to output channel 1 and the left aileron servo to output channel 2. Then, for…

Cheap Fixed Wing Mapping

"Ten thousand dollars?!?! It's just a piece of foam!"

If you've uttered those words, this post is for you.

We will not debate the value of quality or workflow simplicity contained in that $10,000. What we will do is demonstrate how to make a "cheap" consumer fixed-wing…

Looking for challenge

Hi,

after finishing my last project, I'm ready for the next challenge.

However,  right now I can't afford to start another project and buy components for development, although I'd have ideas of course.

So I'd like to offer my experiences in 3D modelling, printing and basic programming skills for some…

Ranger EX 757-3 Auto Mode Test

Completed a successful "Auto Mode" test today using a simple rectangular circuit.  From the "CTUN" graph you can see the roll and pitch response matches the demand.  The aircraft flew stable and as expected, I also repeated this test using 2 different altitudes verifying throttle, airspeed, and rate of climb in…

Comparing Precision of Autopilots for Survey Missions - DJI Phantom 3



We have reached the sixth week in our autopilot precision series. In this series we test different drones and autopilots by flying them on a simple photogrammetry route created in UgCS.



So far we have analysed DJI Phantom 4, DJI Naza-M V2, Mikrokopter Quad XL, DJI A2 as well as PX4. This week we take a look…

More progress...

Most of the parts have arrived so I've been able to get accurate measurements and start on the airframe, a small tricopter. Materials are carbon tubes & 3D printed PLA.

The laws here in Chile are restrictive. You need a license, drone registration, insurance and the drone has to pass inspection - apparently *very* hard to get.

If the drone weighs less than 700 grams its classed as a toy, which means no restrictions other than common sense and being…

Six of the Best and Most Unexpected Uses for a Drone

The FAA predicts there will be 7 million drones registered in the US by 2020. While over half of the drones flying today belong to hobbyists, the rest are owned by private enterprise and various government agencies.

 

However, despite their popularity, drones are…
