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)

Improvements in APM wikis and other documentation

Posted by Chris Anderson on August 27, 2015 at 9:45pm 4 Comments

I'd like to take a moment and call out Hamish Willee and the rest of the documentation team, who every day make scores of improvements to the wikis and other documentation for the APM and other Dronecode project wikis. To call out just one example, you may have noticed the new sidebar/menu system,…


Using ROS Gazebo simulator with ArduCopter

Posted by Chris Anderson on August 27, 2015 at 9:30pm 1 Comment

The future of robotics development, including drones, is powerful simulation, which makes it possible to achieve faster development and better performance by reducing the "trial and error" process of testing everything with physical machines. The Dronecode projects have long used a number of…

Fotokite Phi Tethered Quadrotor on IndieGoGo

Posted by healthyfatboy on August 27, 2015 at 5:37am 2 Comments

Looks really interesting! I like the fact that it gives accountability as to who is using it, seems relatively safe given the prop guards and the flexible props, and at least there won't be any flyaways! This was done by some guys that worked in ETH Zurich's lab.

Here's the IndieGoGo link.…


Theoretical analysis of obstacle detection using LIDAR

Posted by Laser Developer on August 27, 2015 at 4:42am 3 Comments

Small LIDAR (scanning laser) systems can be used for obstacle detection and SLAM from a moving drone. Whilst more work is still needed on the integration of the data from these sensors into the flight software, the theoretical performance can be evaluated based on the specifications of the…


First in the line.

Posted by Aaron Chadd on August 27, 2015 at 3:42am 4 Comments

Over the past few years my company has been experimenting with various types of UAV hardware. We have developed six versions of drones using off the shelf air frames and have tested several types of flight controllers.

 Each has had its pro's and cons and a lot of data has been collected in the past 24 months. We have built UAV's for customers providing custom built aircraft for everything from professional…


Raptor UAS setting records to support Search & Rescue

Posted by NOCO Search and Rescue on August 27, 2015 at 1:00am 3 Comments

Raptor UAS has partnered with Horizon Energy Systems and Northern Colorado Search & Rescue to attempt to set loiter endurance and a distance record using commercially available fuel cell and a small UAV to fly over the North Sea powered by hydrogen gas. Raptor UAS has started a Kick Starter campaign to help fund this Project. We will be using a Raptor E1 and a Horizon Energy Systems fuel cell to fly from Scotland to Norway. A portion of the funds raised will be…
