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)

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

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

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 2 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 2 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…


RAPTOR: Measuring the Flows in Rivers with UAVs

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…


Humanitarian Drone Missions in Nepal: Early Observations

Posted by Patrick Meier on May 4, 2015 at 3:05am 3 Comments

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…


6S mini copter project

Posted by Rob on May 3, 2015 at 8:30pm 6 Comments

This is a work in progress.

It's a rather quadcopter conventional 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

Posted by Randy on May 3, 2015 at 8:21pm 22 Comments

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

Posted by Matthew Coleman on May 3, 2015 at 4:35pm 27 Comments

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!

Posted by NIck Dragolea on May 3, 2015 at 9:30am 7 Comments

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 - …
