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…Continue
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:…Continue
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…Continue
Last November we posted the details and results of the first year of our prototype tilt rotor project. A lot has happened since that post, so we thought we’d provide an…Continue
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…
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…Continue
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.…Continue
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…Continue
Drones provide an “eye in the sky” which can be very useful for water scientists. Many water bodies are often surrounded by difficult terrain, making it…Continue
There are at the very least 7 humanitarian UAV teams operating in Nepal. We know this since these teams voluntarily chose to liaise with the Humanitarian UAV Network (UAViators). In…Continue
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:
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…Continue
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 - …Continue
I still need to buy batteries 4 6S 25C 16000mah batteries and 16 18x6.5 CF propellers, I don't want to be in the middle of nowhere without spares. I will run 2 6S 16000mah batteries or more.The batteries $370 each propellers $100 per pair from…
Part 1 .. DIY Giant Octocopter Build designed for Magnetometer Surveying
Here is my first attempt at building an octocopter. I will post images as I build it.
I built a budget 960mm hexacopter in my spare time last year while working for uranium, copper and…
RenTT writes to let us know that the Chinese APM/Pixhawk developer community is taking off, and there is a new site focused on this called…Continue
If you can ignore the over-the-top music on this video from Top Flight, the MIT spin-off company has some very interesting power technology that can get 100 mile range of one gallon of gas. More details in…Continue
