Philippine Disaster Relief Mapping

3689583699?profile=originalIn the wake of the strongest typhoon in recorded history, Swift Radioplanes LLC of Prescott, AZ recently returned from the Philippines, where they created aerial maps of the extensive damage as part of an open-source project. Shortly before Christmas, the team packed two of their Lynx Unmanned Aerial Systems (UAS) and deployed to the central Philippine island of Cebu, where Super Typhoon Haiyan left behind a magnitude of destruction that is still not yet completely known.

The team spent seven days collecting thousands of high-resolution photos that will be composited into 3-dimensional maps to be given to the Philippine government and the worldwide academic community. “Our main objective was to document the destruction in the remote areas that the government hasn’t gone into,” said Stephen Rayleigh, co-founder.3689583753?profile=original

In the Philippines, the Department of Social Welfare and Development (DSWD) is venturing out into the remote villages, where assessors must physically see a destroyed home before they can give governmental aid. They are reportedly understaffed, and the task ahead of them is far from over. Meanwhile, storms like Haiyan have become more frequent and increasingly severe, a pattern that some researchers say is due to climate change.

The company, which makes the small, hand-launched UAS, donated over 20 square kilometers of imagery, ranging from 2 to 7 centimeters per pixel in resolution, to the DSWD and universities in the Philippines and the United States. Soon, that imagery will be hosted on the Internet under a Creative Commons open-source license, allowing researchers to use the imagery for post-disaster UAS studies.3689583725?profile=original

Embry-Riddle Aeronautical University, where Rayleigh also works as a part-time professor, assisted in the post-disaster effort. The UAS program at the Prescott, AZ campus provided travel funding, spare airframes, and sent one of its students enrolled in the UAS minor.

Rayleigh says the Lynx UAS was built for deployment into harsh environments like the ones they encountered in the Philippines, and the design was inspired by his company’s prior experience as UAS operators in the U.S. Army. “The technology we’ve developed- we want to see it used to help people around the world, and I think we’ve shown that it can.”

Haiyan left as many as 7,986 people dead or missing across the Philippines, according to a recent government tally. Much of the country is still recovering from the massive disaster, and bodies are still reportedly lying under the rubble. “It was a demanding environment, and it certainly pulled at the heartstrings,” remarked Rayleigh, “but it has to be done.”3689583751?profile=original

WASHINGTON – Stephen Rayleigh and Matt Lyon thought they were done with careers in drones after they left the Army in 2010 and enrolled at Embry-Riddle Aeronautical University in Prescott.

Until they met Professor Ray Bedard.

Rayleigh wanted to start a club that would build and fly drones; Bedard had wanted for years to launch drone classes. The club became a class in 2011, with the help of Lyon and Rayleigh’s expertise, and the class grew into a full-fledged drone minor that attracted 28 students when it launched at the school in August.

The minor aims to prepare students to build and fly unmanned aerial vehicles – UAVs, or drones – for a commercial market that doesn’t yet exist.

AUVSI Competition using ArduPilot

3689461373?profile=original

I'm the captain for Team Awesome, the UAS team from Embry-Riddle Aeronautical University, Arizona Campus.  We're headed to the Small UAS competition in Pax River, MD in five days, and we're using an ArduPilot 2.0 equipped airplane. This will be our first year at the competition. We're using the ParkZone Radian powered glider airframe, and the GoPro Hero 2 camera.  

We want to extend a big thanks in advance to the developers of ArduPilot.  We've come a long way in our first year, and we couldn't have done it without you.  

I'll be posting updates from the competition, so stay tuned.  Questions are welcome!

UAS Competition Team

Hi, I'm starting a team at Embry-Riddle in Arizona to go to the UAS competition in Maryland this year.  We're using APM on a custom built airframe, but we're still learning the ins and outs of Ardupilot and Mission Planner.  I've got a few questions:

We're tuning the PID's, and the aircraft pitches down in stabilize and FBW A&B. Should I fix this with RC trim, one of the gains, or initialize the aircraft in a slightly pitch-up attitude?

We're building a pan/tilt gimbal, and I'm wondering- if Ardupilot can make a camera point at a coordinate, can it also tell me what coordinates I'm looking at if I move the camera manually?  One of the requirements for the competition is that we have to find targets on the ground and report their coordinates within 250 ft.  

Is there anyone in the Prescott, AZ area that could give us a hand with autopilot tuning?  We'd really appreciate it!
