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 birthplace of ArduPilot, the world's first universal autopilot platform (planes, multicopters of all sorts and ground rovers). Today the Pixhawk autopilot runs a variety of powerful free and open UAV software systems, including:

  • PX4, a pro-quality copter, plane, rover and VTOL software stack from the Dronecode Foundation
  • ArduCopter, a fully-autonomous multicopter and heli UAV system
  • ArduPlane, a pro-level UAV system for planes of all types
  • ArduRover, a fully-autonomous ground-based vehicle system

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

Sensors for Attitude Estimation

Posted by Matthew Silic on March 22, 2019 at 5:57pm 8 Comments

Hello UAV enthusiasts,

I recently created a slide deck on the topic of sensors for attitude estimation (i.e. gyroscopes, accelerometers and magnetometers). In these slides, I review

  1. Installation considerations,
  2. Stochastic models,
  3. Bias characterization,
  4. Sensor calibration, and
  5. Conceptual models.

The methods and concepts contained in these slides have been "battle tested''. That is, these are the methods and concepts I used…


Developing Long-Range (600km) electric UAV

Posted by Nicolai Valenti on March 22, 2019 at 8:34am 0 Comments

This is our new concept for a long-range fixed-wing UAV. 

The benefits of having a long-range UAV in search and rescue operations as well as in urgent transportation of blood and medicines are astonishing in terms of costs and effectiveness.

Surveillance operations and mapping are also two sectors where a similar air vehicle is essential…


Does the plant protection drone replace the traditional sprayer for plant protection operations?

Vertical Technologies launches the DeltaQuad Pro #INSPECT

To meet the growing demand for dedicated solutions in a wide range of drone enabled inspection tasks, Vertical Technologies have expanded their autonomous DeltaQuad Pro VTOL range with the DeltaQuad…


Challenges in Designing a User-Contributed Motor and Propeller Database

Posted by Charles Blouin on March 15, 2019 at 8:36pm 6 Comments

I will discuss the challenges of designing this database. Searching for the right propulsion components for a UAV is tough. There is not much data available, and what is available from suppliers is not standardized or reliable.…

The Aeromapper Talon Amphibious is the only truly affordable fixed wing UAV system that can be used for inspection and mapping in marine environments.  The UAV system delivers high resolution georeferenced imagery as well as video feed from up to 30 kms from the operators. After completing its mission the UAV later returns and…

Dear Friends,

I'm happy to share wit you last updates about our cubesat project. The great news is that we adopted ChibiOS operating system and start to develop a flight attitude estimation and control for Cubesat based on ardupilot projects. The other challenge are about the telemetry control system and…

Why anti-poaching drones haven't worked well

Posted by Chris Anderson on March 9, 2019 at 8:00am 5 Comments

As an industry, we had high hopes for the use of drones in anti-poaching efforts. But in hot climates everything looks hot to airborne thermal cameras and fleet logistics are crippling. Dogs work much better. Here's a…
