I love this time of year...

Be it the fall, or the spring, I welcome this time of year.  Teaching unmanned aircraft systems operations at the University of North Dakota is a lot of work.  This time of year, however, makes it all worth while.  It's the time when my students have completed their multi-rotors after having studied the components from a systems-engineering perspective.  And these young men and women are not engineers.  They are pilots that truly believe that knowledge, skills and…

Drone test

When I became a test pilot of my father, I’m started to manipulate the Drones and the PX4. I’m is doing the test of the performance of the flight, aerial data adjustments and offer the informations for the customization of flight controller.

My father was a fighter pilot, was a engineer of the Embedded Linux operating system, now, he is a director of documentaries and a photographer. He’s documentary “UAV on the Amazon river” (Link:…

comment on complementary filtering

Complementary filters enable sensor fusion, are easy to implement and eliminate integrating errors from gyro’s or accelerometers. Normally complementary filters are discussed in the frequency domain.  Using simple Python code a 1st order linear complementary filter for determining the…

My Little Success Story

Hi all,

i wanted to write down the journey i did over the past few years after a friend pointed me to diydrones.com.



I was quickly hooked by the hobby virus after assembling, flying and crashing my first rc-plane and afterwards fiddling around to get a APM1…

Multiple tethered quadrotors performing high-g, high-speed formation maneuvers

Τhis video shows tethered quadrocopters flying steadily together at high speeds exceeding 50 km/h in a confined space. With the tether exerting more than 13 gs of centripetal force, multiple quadrotors are able to fly 1.7m- radius circular trajectories in formation across different orientations in space and then successfully perform a coordinated braking…

Is this possible? An autopilot in the sky - Project SensePod - part 2

I've been working on a universal pod, to carry additional equipment on drones. While I was playing around with my 3D program of choice (Shade 3D) I got the brilliant idea to add a set of small wings to my pod.…

Hovering UAV with cyclic control with only drive motor

It's a coaxial rotating VTOL setup that is more efficient than a quadcopter because of larger, fewer, rotors and is ofsimilar mechanical complexity. The catch is that the hub needs to be custom though but seems doable (was 3D printed in this example but probably needs to be machined for larger scales) and requires a custom motor driver that allows PWM access…

6S mini copter project

This is a work in progress.

It's a rather conventional quadcopter but with a few tweaks.

The goal of this project is to make a small, transportable, waterproof, sturdy quadcopter that can carry go-pros and similar cameras.

Here's where we are so far:

  • 3D printed,…

Multi-Vehicle testing with APM:Copter, Tracker and Mission Planner

For some tasks (like Search and Rescue and mapping) what you can do with one vehicle, you can probably do faster with multiple vehicles.  To test how well it works in practice I tested…

The uNode

A distributed and scalable autopilot architecture is attractive to me due to space and sensor positioning demands on my airframes.  The existing range of autopilots simply doesn't fit.  The uNode (microNode) is the result of my desperate attempts to fix this.  uNode is a very cutdown…

Cheerson CX 10 - Surprising build quality!

I finally got around to writing a review for this little drone I've had for a few months now. I bought it for about $17 and it still seems to be flying even after it got slightly chewed by my dog (pictures taken before that happened!). It's a pretty cool drone.. and pretty safe to fly too. I can't envision much going wrong unless if you lack common sense and fly it into a group of people/ animals. It's great for learning the ropes for any new flyers - …
