Welcome!
This is a site for all things about amateur Unmanned Aerial Vehicles (UAVs): How-to's, videos, discussion and more (you can read more about us here). Please use the tabs above to navigate the site.These are our Arduino-based open source autopilot projects:
* ArduPilot, a very low-cost (the basic board is just $24.95!) autopilot
* BlimpDuino, an autonomous blimp with both infrared and ultrasonic guidance
Other UAV/autopilot projects and code, by processor and OS type, are here.
Earlier DIY Drones projects, including Lego and cellphone autopilots, are here
FAQs:
* I'm new to all this--where do I start?
* Are amateur UAVs legal?
* Can you explain how IMUs using gyros and accelerometers work? Do I need both?
* I'm confused by all these terms! Is there a glossary? (yes!)
You can find a list of external UAV resources, including commercial UAVs and other open source UAV projects and code here.

Transverse Rotor UAV: Articulating Arm CONCEPT
This is a lunchtime sketch: will make this quick.
Two independent brushed (thinking weight and cost here) motors directly drive counter-rotating rotors.

Position & Wind Extended Kalman
Wrote up a wind estimator today. It is based off of a simple model which requires very little inputs from sensors.
psi - true heading (not course over ground)
theta - pitch
airspeed
GPS lat and long
It is a simple model. The wind model has no dynamics which helps

Easy Star Fiberglass Fuse
I'm in the process of making a mold for a easystar fuse. I used the replacement foam fuse from the local hobby shop and mounted it to a board, filled the pushrod channels and servo holes on the outside. Fuse plug is painted and waxed.
I must decide where to install hatches (if any). I still have the removable canopy as a seperate part, and will mold the wing insert seperately.

Webbies 2009 - winners and judges comments
Eurofighter Typhoon, Amsterdam Schiphol International airport and Things in the Sky blog have triumphed at Flightglobal's annual aviation web awards. The Webbies 2009, now in its second year, celebrate the best and brightest in aviation websites and their social media activities. The Eurofighter website won the Best Aerospace website for its interactivity and games element. Amsterdam's airport triumphed in the Best Airport category for knocking down language barriers, and the judges were impressed with the blog, Things in the Sky for its "compelling visual content". The Webbies 2009 had two new categories: Best Enthusiast/Community Website to honour the website that deliversHoneywell to hush, bolster reliability of micro air vehicle

The United State Air Force is working on new technologies that mean some of the unmanned aerial vehicles (UAVs) of the future will have in-flight refuelling capabilities, longer range and new strike capabilities. UAVs are moving beyond surveillance and kinetic strike capabilities to include, for example, directed energy weapons, the US Air Force’s chief scientist Werner Dahm, told delegates today at the Singapore Airshow’s Aerospace Technology and Maintenance conference. Longer-range missions means the UAVs will require highly efficient engine technologies and in some instances this will involve using solar energy and regenerative energy capabilities, says Dahm. He also says the US Air Force is working to develop UAVs that have in-flight refuelling capabilities and can use the US Air Force’s existing fleet of air tankers. The US Air Force used a Learjet “as a surrogate for the unmanned aerial system platform” and “the Learjet successfully got into contact posNews from UAVSI
Northrop Grumman Global Hawk Aids Haiti Relief
Northrop Grumman, which has an exhibition chalet at the Singapore Airshow 2010, said in a press conference Wednesday that it has been flying a Block 10 iteration of its Global Hawk over the last few weeks for the Haiti earthquake relief effort. Edward Walby, director of business development for Northrop’s Global Hawk Systems division, said that the UAV was deployed from the Naval Air Station Patuxent River base in Maryland, which is monitored from the Beale Air Force Base in California, to fly [More]Military Adapts Robotics Operation to Afghanistan
The shifting military focus from Iraq to Afghanistan is also shifting the way the military repairs its ground robots, says a U.S. Army project manager. "The static operation in Iraq, bring the robots to use and we'll fix them, doesn't work in Afghanistan," said Jeff Jaczkowski, deputy program manager of the Robotic Systems Joint Project Office at U.S. Army Tank-automotive & Armaments Command (TACOM). Jaczkowski spoke at the opening day of AUVSI's Unmanned Systems Program Review 2010, which [More]EADS to Sign MOU With Singapore Universities
Representatives from EADS Innovation Works Singapore revealed at the Singapore Airshow 2010 that they are signing a memorandum of understanding (MOU) Wednesday morning with two Singapore universities in a move to further its ties to the burgeoning technology hub. Under the agreement, both the National University of Singapore and Nanyung Technological University’s various engineering departments will perform research for EADS’ use. In exchange for the information, the company will sponsor the [More]NATO Affiliate Defines Classifications of UAVs, System Employment
In a move that might eventually formalize classifications of unmanned aerial systems, Air Cdre. Jan van Hoof of the NATO-affiliated Joint Air Power Competence Centre revealed 31 Jan. at AUVSI’s Unmanned Systems Asia-Pacific that the center recently agreed upon categoric standardizations of different types of UAS. Specifying exactly what constitutes, for example, a mini UAV could increase communication effectiveness among nations regardless of which system it happens to have contracted, said van Hoof. The [More]Fiscal 2011 Defense Budget Boosts Unmanned Systems
The Obama Administration on 1 Feb. unveiled a $708 billion fiscal 2011 defense budget that calls for more unmanned aircraft flights over Iraq and Afghanistan and buys more UAS, while eliminating part of the U.S. Army's former Future Combat Systems. "FY 2011 investment spending will continue the expanded use of Unmanned Aerial Vehicles in war zones. The request of $2.2 billion supports the plan to increase Predator-Class CAPs [Combat Air Patrols] from the current 37 to 65 by FY 2013," according [More]© 2010 Created by Chris Anderson
