Did some test flights this weekend for my precision landing program(A detailed explanation of this project can be found here.). They were short due to the cold conditions and battery life but beneficial. I was able to attempt the landing four times. All attempts went well in that the Copter didn't crash and held its position using vision. Only one attempt succeeded. Two had to be aborted due to low battery and poorly secured landing mat. One missed the target. I think it was because of wind.

Next I plan to implement a more robust controls strategy which should increase accuracy.

Was glad to be part of this meeting. And here's the write-up about the recent event from one of the attendees.

---

(Pasay City, Philippines) - The Civil Aviation Authority of the Philippines (CAAP) recently opened its doors to a “UAV Industry Stakeholder” Conference with various Philippine Unmanned Aerial Vehicle (UAV) operators, as well as the Philippine Remote Control Congress (PRCC) and recreational RC flying fields on February 27, 2015 at the CAAP Director General’s Conference Room.

CAAP officials and department heads that were present at the Conference. Capt. Beda Badiola – Assistant Director General and Officer-in-Charge (OIC) of the Flight Standards Inspectorate Service; Capt. Efren Rocamora - OIC of the Regulatory Standards Department; Capt. Manuel Foronda – OIC of the Licensing Department; Capt. Nes Del Castillo – OIC of the Flight Operations Department and Engr. Alimben Nara of the Airworthiness Department.

A number of UAV Operators attended the forum which encompasses a wide berth of industries and backgrounds that utilize multirotor / fixed wing UAV’s.

• The hobbyist/recreational flyer who simply want to fly and enjoy the new capabilities of UAV aircraft. To aspiring aeromodelers who plan to transition into some sort of UAV-related business in the future.
• New freelancers who want to know more about the regulatory process and professional freelancers trying to quickly comply in order to formalize their current projects.
• Companies utilizing UAV’s for aerial photography, remote sensing and survey purposes. Primarily for urban planning, real estate and engineering applications.
• Movie equipment rental industry and live event companies with UAV services.
• Industrial applications to improve safety, increase efficiency and cut cost for various industries ranging from farm lands, oil and gas, mining, construction inspection and including search and rescue considerations.
• Local developers, integrators and manufacturers of UAV’s.
• Educational, academic, research, training institutions and related works.
• Distributors of UAV products.

The Conference was chaired by the two founding members of Philippine Remote Control Congress (www.prcc.com.ph) and both are UAV Developers and Integrators of the technology. Obi Mapua, CEO of Mapua Institute of Technology from 1994 to 2000, one of the leading engineering universities in the Philippines; and Erwin Dematera who has commercial pilot's license and the first to obtain a CAAP UAV Controllers license (UAV Pilot) Certification.

The main topic of discussion is the CAAP’s Memorandum Circular MC 35-14 which is the recent amendment of the Philippine Civil Aviation Regulations (PCAR) Part 4 and Part 11 in the registration UAV’s, its controllers and operators. The recently concluded Conference gave a chance for the UAV operators to seek consultation and guidance with regards to the new UAV regulations.

After half a day of invigorating discussions between the CAAP, UAV industry stakeholders and recreational aeromodelers. The UAV Industry Stakeholders Conference came to a successful conclusion. The Conference achieved several important outcomes with a very positive impact in the Philippine UAV industry, as well as the recreational UAV and RC aeromodelers.

All thumbs up for the Civil Aviation Authority of the Philippines, and the Philippine UAV Industry!

I don't normally pass along anti-drone op-eds, but this one from the Chicago Tribune is the most extreme I've seen and interesting in how it discounts the positive uses as trivial (pizza delivery) and focuses on the weapon risks.

In the overnight hours last week, authorities in Paris spotted unmanned drones buzzing the Eiffel Tower, the Bastille, the Place de la Concorde the U.S. Embassy and other high-profile landmarks.

Why? It's still a mystery.

But whatever the reason, this swarming incident has convinced me: While there's still time — if there's still time — we must ban drones.

I don't mean restrict the areas or altitudes where they can fly. I don't mean tighten regulations on the purposes to which private citizens and law enforcement can use them. Many jurisdictions have already instituted partial crackdowns.

I mean ban them outright. Prohibit their ownership and use for all but the most limited law-enforcement and military purposes. I mean pass legislation and create international norms to treat these small, unmanned flying vehicles the way the law treats machine guns and chemical weapons — as devices so inherently fraught with potential peril that whatever positive uses they may have aren't worth the risks they pose.

These nimble, remotely piloted aerial machines are a significant threat to public safety, even when flown by people who mean no harm, and an obvious threat to privacy.

Drone enthusiasts wax optimistically about what a boon they are or will be to photographers, retailers, farmers, bridge inspectors and so on — how cheap and easy drones make it to do important jobs.

I fret pessimistically about what a boon they are or will be to terrorists, criminals, goofballs, snoops and so on — how expensive and difficult it will be to create security barriers against their malign use.

An anecdote: In September 2013, members of the German Pirate Party flew a quadrocopter over the crowd at a campaign rally in Dresden as a gesture of protest, and crash-landed it more or less at the feet of German Chancellor Angela Merkeland her defense minister.

The device was basically harmless, but the incident — like the incident in January, when a lost drone crashed on the White House lawn — was ominous. What if it had been weaponized? A flying IED?

A drone capable of delivering a package to your door will also be capable of delivering a small bomb. And I know this sounds alarmist, but poke around online a bit, and you'll see that police departments all over are increasingly concerned about malicious uses of drones as well as the inevitable accidents when they malfunction or wander into protected airspace.

They can fly under the radar, literally and figuratively, and require sophisticated technology to safely disable. Commercial aircraft, power plants, outdoor gatherings and even moderately fortified private homes are vulnerable to stealthy incursions from above.

If only. These things are no longer glorified toys. They're getting cheaper and more sophisticated all the time, and the costs of protecting ourselves from them will rise accordingly.

And for what? So pizzas and prescriptions can one day be delivered faster? So we can enjoy more stunning aerial videos such as the tour of Chicago in winter posted to the Soaring Badger Productions YouTube site? So we can more easily keep track of our crumbling infrastructure? So farmers can monitor their crops from the comfort of their dens?

The number of uses — real and on the drawing board — is growing along with the consumer and commercial constituency for drones. Which is why we should prohibit their manufacture and sale now, before we get a heavily financed National Drone Association funding lawmakers at every level of government and trumpeting the idea that it's a right, not a privilege, to keep and fly wee helicopters.

We'll be sorry if we don't strike an international treaty banning the civilian use of unmanned aerial vehicles and sharply limiting their use by law enforcement and the military.

Do I know how preposterous and reactionary this sounds? How it echoes of the vaporous panic with which history's fools have greeted nearly every technological advance from the printing press to the Internet?

Do I realize the futility of railing against the tide of progress with feverish hypotheticals?

I do. And I know there's a good chance that my yet-unborn grandchildren will one day find this column in a compendium of retrospectively amusing journalistic hysteria and have a good laugh at my expense over a drone-delivered takeout meal.

A few weeks ago we announced a partnership with Canonical to support the next generation of drones that will be connected to the internet, update automatically and will have access to an app store for drones. Following up with our passion for bringing Linux-based drones to the market we are happy to share that the first apps are starting to show up in the store and are freely available.

Our goal is to create computers with the ability to fly that would allow a big community of Linux experts and hackers to jump into robotic application development using the best tools and frameworks (ROS) for robotic application development. We plan to release soon an image for Erle-Brain that will allow you to play with the store and make Linux drones so if your are interested go and fetch yours from the store.

The “hello drone” app is teared down and explained in this article:

Support for hardware access in Snappy Ubuntu Core has recently been announced so expect more apps to be released  over the following weeks interacting with hardware. Our approach will be focused on ROS.

I don't know any more than what 777BlueAngel notes on his Youtube page:

Finally was able to get one of the bots out onto the water. For this test, I chose an area of San Francisco Bay that is subject to strong currents during the tide changes. As the tide was going out, the current was about 3 knots. The bot did fine. There were plenty of settings to tweak and a few adjustments of the Pixhawk PID had things working smoothly.

Some takeaways from the test.

Turn radius: Once I threw the switch into autonomous mode, I notice some squirrelly behavior from the bot. Checking my list I realized that I still needed to verify the turn radius. I originally estimated the turn radius to be about 3 meters. I was waaaaay off. The radius turned out to be around 7.5 meters. Once I updated that little nugget, the bot handled the waypoints with ease. 

Weight: Getting weight distribution right can be a pain. I had to stop the bot on the water a few times to adjust battery/ballast positioning so the bot would track better.

Overall a successful mission and One step closer to launch!

More updates soon.

The Queensland University of Technology are employing drones to assist in monitoring Koala population and distribution. This is important work that could help to improve our understanding of this incredibly vulnerable species and improve the resolution of data collected in our annual Koala Count.

Excerpt from abc.net.au news article:

"Queensland researchers are hoping drones will aid in the conservation of threatened species like koalas.

Traditionally, koalas were counted by people on the ground but now they can be tracked by robots from the air.

Researchers fitted drones, or unmanned aerial vehicles (UAVs), with infrared cameras to better detect the creatures.

QUT drone technician Gavin Broadbent said they were a little bit sceptical it would work, but they were filled with confidence when the images came through.

"We saw the koalas were very distinct compared to the trees and the environment so we thought, yes this is absolutely a proof of concept," he said.

Hovering above the tree tops, the cameras detect the animals' body heat and beam pictures straight back to the team of researchers on the ground.

Computer software helped distinguish koalas from other creatures that might be in the trees.

The first test flight was in bushland surrounding Australia Zoo on Queensland's Sunshine Coast earlier this month."

Hi guys, 

First i'd like to thank all of you for your comments regarding our first post (http://diydrones.com/profiles/blogs/fpv-gimbal-for-zoom-camera?xg_source=activity). Your comments helped us with technical issues and got us really positively motivated. 

Theory became reality

We have just finished the first week of tests and we are more than happy to share our results with you. We are now flying FPV with 3 axis gimbal with a 27x zoom, so lightweight, that it can be easily attached to Iris+ or Phantom, or a SkySurfer1400 plane. And the experience is amazing. It is very natural to fly with the zoom and it gives you a lot of freedom. It really feels, that this is a must have feature in all FPV models.

More work to come

The gimbal gives some minor vibrations when the camera is at full zoom, but we plan to improve it until we get the maximum quality. We still see room for improvement, and it's only our first week of tuning :).

When we hit the maximum level of mechanical stabilisation we plan to test a digital camera with zoom, with a software stabilisation. The quality of video can improve dramatically by replacing camera to a better one.

Some specs:

-27x zoom (3,5mm - 94,5mm)
-PWM zoom control (from receiver)
-1/3'' SONY 960H EXview HAD CCD II (700TVL)
-RTF weight 360 grams /0.79 lbs (including camera, autofocus lens, brushless motors, a dedicated dampening plate and gimbal controller)
-3S Voltage input.

Jacob and I thought about building few sets for you to test. If you're interested just email us (vertigofpv@gmail.com). 

An Autopilot in the clouds - part 6.

The loooong wait...

Weather here in Denmark is optimal right now, if you’re either a fish or create 110% waterproof hardware. So while waiting to get a decent chance for the UTV1 to get it’s maiden flight, I thought I’d shortly describe a little tool I made to ease mission planning and execution.

The UTV1 has the ability to send and receive telemetry through the GSM net, which make it very appealing to spend a little time on making a graphical front end that can reside on a laptop, that allows you to see the usual stuff the drone GUI’s show (position, status etc), and also allows you to control the craft to some extend.

I’ve build my little GUI with inspiration from the control center of the Apollo era, with a simple button based interface, were buttons light up on error events, state changes etc.

The GUI also allows you to directly chat with the drone (video is included). I’ve kept the voice feedback, because this has proven to be very useful when your eyes is on the sky and not the screen.

1 - A text area that shows the raw messages that is being sent from the vehicle - great for nerdy debugging.

2 - A map area that shows the last know location of the drone.

3 - A text input field that allows you to chat with the drone for mission planning etc..

4 - A representation of the autopilot statemachine - the row of buttons light up as the vehicle makes it through it’s mission.

5 - Button that lights up when connection is established

6 - Button that indicates if manual RC-controller flight has been activated

7 - Button that shows if the statemachine has been brought into terminate mode (which just means that a pleasent glide landing is being attempted), can be manually activated or activated by the range guard mechanism.

8 - A number of warning lights that lights up in various scenarios (pretty self-explaining)

Telemetry can be updated 4 times/second but I keep it to a minimum 1/s for the time being.

Below you'll se a short video of how a set of waypoints can be entered by using the built in chat client - in effect you are actually talking to the drone :) This is a rudimentary first version, with fixed altitudes etc..

Those GoPro people are running out of ideas at this point.... If you look closely im pretty sure someone just gave her a DJI controller that was non operational. l

For those of you who have not been following the latest news from the FAA this concise article should clear the mind about the impact of new regulations and the industry's opinion.

Keep in mind: The rules won't become law until mid-to-late 2016 at the earliest, though 2017 is a safer bet.

RCLogger, the company who brought one of the least expensive mini brushless quads to market with the EYE One Xtreme, is now working on a micro-brushless gimbal for 200 sized quads. The gimbal will be capable of carrying the 1080p capable Mobius camera, a favorite among hobbyists for its size, quality, and price. The entire setup, including aluminum-framed brushless gimbal, dampened mount, control board, JST connector for power, AND camera is expected to weigh in between 100 and 110 grams. Early production models tipped the scales at 108 grams with camera mounted, and 70 grams without, according to RCLogger.

The gimbal can auto-detect power from a 2s or 3s power source, which can be provided from a separate battery or a split lead from a flight battery. Out of the box the gimbal will be pre-tuned for the Mobius camera, but does provide a USB port to allow users the opportunity to change parameters, or upgrade firmware. It will also allow the user to manually adjust the pitch and roll of the gimbal in-flight, if the users radio system is capable of such control. The mount is designed to work with most 200 sized brushless quads.

Price and release date have not been officially set, but an April release has been hinted. RCLogger has also hinted pricing will make it extremely competitive in the 2D gimbal market, especially considering its small size.

The ArduPilot development team has a special treat for fixed wing users today - a double release!

• A new stable 3.2.3 release with 3 fixes for 3.2.2
• A new 3.3.0beta1 release with a lot more changes for wider testing

The 3.2.3 release is a minor update to 3.2.2 with 3 fixes:

• A fixed to relative altitude drift when on the ground before takeoff
• fixed TKOFF_THR_DELAY to be able to be up to 127 (for 12.7 seconds)
• fixed INS_PRODUCT_ID (it was being reported as zero)

The most important fix is for the altitude drift, which could cause a poor altitude reference if your GPS altitude drifted while disarmed. The bug showed up as a significant drift in the reported relative altitude on the ground station when the aircraft was disarmed with the EKF enabled. The root cause of the bug was a disconnect between the EKF origin and the planes origin for relative altitudes. It only happened when the GPS altitude varied significantly while disarmed.

Start of 3.3.0 beta releases

The 3.3.0beta1 release has a lot more changes in it. The largest of the changes are internal, such as performance improvements in the NuttX operating system on Pixhawk, but given the size of the changes we want as many test users as possible.

Changes in 3.3.0beta1 include:

• a new SerialManager library which gives much more flexible management of serial port assignment
• changed the default FS_LONG_TIMEOUT to 5 seconds
• raised default IMAX for roll/pitch to 3000
• lowered default L1 navigation period to 20
• new BRD_SBUS_OUT parameter to enable SBUS output on Pixhawk
• large improvements to the internals of PX4Firmware/PX4NuttX for better performance
• auto-formatting of microSD cards if they can't be mounted on boot (PX4/Pixhawk only)
• a new PWM based driver for the PulsedLight Lidar to avoid issues with the I2C interface

I'm expecting a lot more changes will go into the 3.3.0 release as we still have a lot of pending pull requests. I will be doing regular beta updates as new patches go in (once they are flight tested).

Happy flying!

Announcing UAV Challenge Medical Express 2016 at an unmanned systems conference associated with the Avalon Airshow, event co-ordinator Dennis Frousheger said the 2016 challenge was designed to push UAV technology to the limit.

“It’s unlikely that traditional fixed-wing unmanned aircraft or small multi-rotor vehicles will be capable of meeting this challenge – new hybrid flying robots will probably be required,” said Mr Frousheger, an engineer in CSIRO’s Digital Productivity Flagship.

“This time, our hapless bushwalker is stuck in a clearing in the Australian Outback, surrounded by floodwaters, and his doctors have requested an urgent blood sample be sent to them.

“He’s found his way to a clearing and has emailed his GPS coordinates.

“Joe’s located in an area surrounded by obstacles so teams will need to develop systems capable of understanding the landing site, and plan and execute a landing – all of this at a distance of at least 10kms from their location.”

To complete the mission, teams will need to deploy an aircraft from a small town outside the flooded area and have it fly autonomously for at least 10km to find Outback Joe.

The robot aircraft must locate Joe and automatically land nearby. After Joe places his blood sample into the aircraft, it must take off and fly quickly back to the town.

UAV Challenge co-founder Professor Jonathan Roberts, a QUT robotics expert with the Australian Research Centre for Aerospace Automation, is not expecting a winner in the first year of the new competition – but is happy to be proven wrong.

“It took eight years to save Joe in our Outback Rescue competition – that’s with more than 2,000 people from 350 teams working on the problem and sharing their knowledge,” Professor Roberts said.

“We’re expecting many of those teams to take up the medical express challenge, along with others keen to push the envelope for UAV capabilities.

“The prize for saving Joe will again be AU$50,000.”

The competition takes place in September 2016 in Outback Queensland, Australia.

Professor Roberts outlined the results of the 2014 Outback Challenge – Search and Rescue and the scope of the new Medical Express competition at the Australian Association for Unmanned Systems’ conference, A Gathering Storm: Unmanned Systems Outlook in Australasia, held over three days in Melbourne and Avalon, Australia.

He said the full rules for the UAV Challenge Medical Express competition will be released in the coming weeks.

The UAV Challenge will also release new rules for the high-school student competition to be held during the 2015 September Queensland school holidays. The high-school event will also have a medical delivery theme.

The rules of both the International Medical Express Challenge and the high-school challenge will be posted on this site as soon as they are released.

Mexican immigrant Jordi Munoz says that waiting for his green card after he first moved to the United States made The immigrant who became a drone firm boss him feel as if he was living "in a big jail".

At the time he was 20 years old, and he and his girlfriend had set up home near Los Angeles.

Yet he could not legally work, or even enrol at a college, until he got the identity card that proved his right to live and seek employment in the country.

But instead of just sitting around during his frustrating seven-month wait back in 2007, Mr Munoz, a keen model plane enthusiast and computer programmer, started to build his own drone in his garage.

A drone, technically an unmanned aerial vehicle, is essentially a very high tech and stable version of a remote-controlled plane with a camera attached to take aerial photographs or record videos.

Using what parts he had to hand, Mr Munoz made the drone's autopilot system by taking the motion sensors from a games console remote control.

To attach the microchips to circuit boards he heated them up in a domestic oven.

Fast forward to today, and Mr Munoz, now 28, is the co-founder of the largest US-owned manufacturer of commercial drones.

The business, 3D Robotics, is expected to enjoy sales of $50m (£33m) this year.

Key investment

Back when Mr Munoz was working on his first prototype, he started to put up posts about his progress on a website for other DIY drone enthusiasts.

In addition to the advice and encouragement he got from fellow hobbyists, one man was so impressed that he sent Mr Munoz $500 (£325) to help carry on his work.

A handful of members still here can say they were there for this story, my how things have changed. Fair play Jordi, fair play.

Hi,

All of us are uncomfortable with the landing gear of Pocket Drone, and I'm last days thinking about it and this is a prototype of what can be a descent landing Gear.

I was at Leroy Merlin and bought some "pipe holders" - a bag with 4 pieces.

So, first I measurement and I fold this holder like this:

I cut exactly on the and of the fixation hole and then, I mark the size of the PD's "retractile" landing gear and start to saw the piece like that:

After some adjustments - Aluminium is not a nice thing :)

This are the Landing gear installed at Pocket Drone

Some details.

Even in this beta version, this landing gear works better than the original ones.

I will do some improvements - install some rubber between the landing gear and PD's arm - to improve vibrations absorption and improve landing gear stability - I would use work "fixation" but the main idea and why I backer this PD is to has a pocket so a fixed landing gear is not my scope.

I will post more updates soon - after my research about rubber - I don't know a lot about it too - so if someone can help I will appreciate.

for now, this is how PD is:

Update - Beta 2 version :)

Well,

This solution was ok but not nice so......

because PD landing gear support is a "circle hole" and my landing gear are flat, the landing gear was not completely fixed/stable:

And the combination of plastic + metal for a landing gear was not the best option for impact absorption, so I went to a paper store and bought some rubbers :)

After try all - the green ones is too soft and the pentel was too hard, hotwheels was too fins so I choose the strange rubber with barcodes:)

After looking the default PD holders and my eternal wish for -  easy to remove and install I take the rubber, done some measurements and start to cut.

Since my first Crius AIOP I acquire a lot of experiences about vibrations and absorption and how great is the rubber how great will be the absorption - and for a landing gear it is important.

I just measure and cut the rubber like that:

This is the bottom view of the rubber. There is a role - that is because the original landing gear has an "arm" to keep the original landing gear locked - Ok is a joke but in the concept of the original landing gear someone has this idea - so, this hole will be over the little arm, and with that the rubber stay close as possible to the arm.

So this is how the rubber are attached to the arm:

Look the original landing gear support - the role to attach the landing gear is the most close to the metal landing gear - to fix the rubber on the arm - amazing you don't need glue or nothing - how I cut the rubber almost exactly size of the space between the landing gear holder plus the metal landing gear - they both exert pressure and with that the landing gear and the rubber stay on place and all my goals - impact absorption and a good landing gear for PD are meet.

The landing gear at the background was without the cut on the bottom of the rubber - so the cut is important :)

Was little late when I finished so I didn't fly yet but I drop PD from 10/15 centimeters to the ground and the landing gear works.

I will fly today and post comments - but the next step is improve the metal - I think a EVA or another plastic think in the middle of the landing gear will improve strength and resistance.

I went to my local Hobby Shop and they introduced me to the Tactic radios and I like the form and price. I have had an APM 2.6 for some time and thought why not get it going. when it came tome to set up the switch to control the flight modes i ran into some issues. I could not find a good source of information to set my system up. It looked like I may have made a misguided choice in radios as hardly any in the forums were using the Tactics let alone the TTX850. I found a few articles that kind helped but it meant me using up two RC channels to get the mixing I was looking for. I found some help on the rcgroups site that helped. I came across an article on the DIYDrones forums that seem to get me started.  I loosely followed the Specrtum DX8 2 switch mix from DIYDrones . Below is what I came up with and will allow you to use just one channel and mix two switches (one 2 position and one 3 position) to get all six flight modes on a Tactic TTX850.

Here is my set up:

CH 6 >Reversed >Travel 85% 85%
CH6 assigned to SW H (Offset 0%, Speed 100%)

Mix 1: CH6 -> CH6 
Rate L: +0%
R: +0%
Offset: +0%
CTRL: SW G 0 Pos (L(1), M(0), H(0))

Mix 2: CH6 -> CH6 
Rate L: -53%
R: -59%
Offset: +0%
CTRL: SW G 1 Pos (L(0), M(2), H(0))

Mix 3: CH6 -> CH6 
Rate L: -80%
R: -80%
Offset: +0%
CTRL: SW G 2 Pos (L(0), M(0), H(2))

This will give you the following Flight Modes (FM). This setup allows you to cycle through the flight modes is a sequential switch order with both switches starting at the "0" position. FM 2 and 3 are entered by flipping SW G (3 Position Switch) to position 1 and 2 respectively. To continue down the FMs you flip SW H (2 Position Switch) to position "1" and that will enter FM 4. For FM 5 flip SW G to position "1". When SW G is flipped to position "0" it will enter FM 6.

Switch 1-Position/ Switch 2 -Position = Flight Mode

H-0/G-0 = FM 1
H-0/G-1 = FM 2
H-0/G-2 = FM 3
H-1/G-2 = FM 4
H-1/G-1 = FM 5
H-1/G-0 = FM 6

Hi,

Inspired by Forrest Frantz with his multicopter building techniques using glue only, no screws (see here) , helped by him and Jon on frame and motor aspects of the build, we achieved and built what I believe is a world's record : the lightest 2-axis brushless gimbal carrying a full HD camera.

I will post and share building details in the next few days here.

Cheers,

Hugues
