Welcome to DIY Drones!

Welcome to the largest community for amateur Unmanned Aerial Vehicles! Use the tabs and drop-down menus above to navigate the site.

This community is the home of ArduPilot (now known as APM), the world's first universal autopilot platform (planes, multicopters of all sorts and ground rovers). Today the Pixhawk and APM 2.6 autopilots run a variety of powerful free and open UAV software systems, including:

  • APM:Copter, a fully-autonomous multicopter and heli UAV system
  • APM:Plane, a pro-level UAV system for planes of all types
  • APM:Rover, a fully-autonomous ground-based vehicle system

I'm new to all this--where do I start?                   Are amateur UAVs legal? (yes)

I love this time of year...

Posted by Benjamin Trapnell on May 6, 2015 at 6:30pm 1 Comment

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

Posted by Link Zhang on May 6, 2015 at 1:30pm 2 Comments

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

Posted by andre van calster on May 6, 2015 at 9:10am 3 Comments

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…

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

Posted by IKE on May 5, 2015 at 1:18pm 2 Comments

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

Posted by Jesper Andersen on May 5, 2015 at 12:18pm 5 Comments

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

Posted by Dan Nguyen on May 5, 2015 at 9:00am 6 Comments

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…
