Autonomous Quadrotor Flight Based On Google's Project Tango





 


Now here we go! Project Tango and UPenn whats not to like. Its always interesting to note that the Asctec machines are in nearly every cutting edge video. I always call that out because they are such nice people that just carry on in a confused market.



Parrot scored with the product placement there ;-)

A Bulletproof Failsafe, Switchable Power Supply, and Cutoff Switch for $10

A Bulletproof Failsafe, Switchable Power Supply, and Cutoff Switch for $10

 




After getting my plane stuck in a tree three times now thanks to Google Maps elevation errors, I wanted a way to shut down my aircraft remotely. My latest mishap resulted in my plane being held hostage overnight and over-discharging a perfectly good battery. The relay control with APM is no longer supported, but with the help of Chris Anderson I found a cheap solution.

To complete this project, you will need two relays, and a RC Switch. Instructions for wiring the RC Switch can be found here.

I am no electrical engineer, so please forgive my scratchings (see drawing below). This is the diagram for the power cutoff switch:



The basic principle for a cutoff switch is this:

1. A 5V power supply runs through the USB port to power the APM.

2. The main battery is connected to the normally open NO side of relay.

3. Control and power for the RC Switch comes from the APM analog rail, in my case, servo A10.

3. The coil of the relay is controlled by the LOAD circuit of the RC Switch. When the RC Switch energizes the coil by a command from the APM by moving the servo to the HIGH position, power from the main battery is sent to the ESC, BEC, and power module.

4. Disconnect the 5V power. When you get your plane stuck in a tree, you can disconnect the main battery with a servo command from your ground control station, by setting A10 to the LOW position.

Here it is in real life:



What is really cool about this is that you could operate the RC Switch directly from the receiver for a failsafe. In the case of a fly-away a Spektrum receiver goes into failsafe mode (assuming you set it up) and the PWM to the RC Switch could be set to the OFF position in failsafe mode, cutting all power to the aircraft. In this case it would be beneficial to keep your 5V power supply attached to the APM to power your telemetry. If you wanted to be super cool, you could wire a third relay or controller to a chute that deployed when the failsafe activates!



A switchable power supply would only have a small variation, with no 5V power supply for booting up the APM. A second battery would be used instead. I have not tested this, but I remember another user stating a need for it earlier this year. See below:



Every time I have been stuck in a tree, it has been because of a map error, not a map reading error. Batteries are expensive, and this simple, $10 device can save you a whole lot more in batteries. It could also save your craft from an expensive or dangerous flyaway. I hope this helps somebody out.

FAA considering accelerated approval for low-risk commerical use of drones

FAA considering accelerated approval for low-risk commerical use of drones

 


This sounds like good news, but we'll have to see the details to know for sure. From Bloomberg:

U.S. aviation regulators said they are considering a streamlined approval process for flights of small unmanned drones for film making, utilities inspections, farming and other low-risk operations.

With the first regulation allowing commercial drone flights at least a year away, the Federal Aviation Administration is looking at ways to grant approvals for limited applications before then, said Jim Williams, chief of the agency’s unmanned aircraft division. The FAA is already fielding requests, he said in a speech in Orlando, Florida, today.

While such flights aren’t yet permitted, businesses have already been using drones to film sporting events, promote real estate and map land. Industries including agriculture, film making and inspections of utilities and oil and gas facilities have now approached the agency and are considering asking for a formal process for expedited approvals to fly, Williams said.

It expects to propose a rule allowing commercial drones weighing less than 55 pounds (25 kilograms) by November, according to a schedule of rulemaking efforts.

South Africa: Film industry concerned about camera drone ban | sUAS News

South Africa: Film industry concerned about camera drone ban               



microdronersa

CONCERN is growing in the local film industry about the economic impact of the SA Civil Aviation Authority’s (SACAA) ban on unmanned aerial vehicles (UAVs) or camera drones frequently used by film-makers for action scenes and nature documentaries.

UAVs are aircraft that fly without a pilot and can be controlled remotely by someone on the ground, in another aircraft or by computer.

Earlier this month the SACAA urged people to refrain from using UAVs without approval from the authority.

The SACAA did not approve the use of camera drones as there are no regulations guiding its use. Anyone using these UAVs did so illegally, the SACAA said.

UAVs are used in the production of feature films particularly in action scenes, for tourism commercials and by nature conservationists to track the movement of rhinos.

Kabelo Ledwaba, from the SACAA said it had not given approval to any organisation to use camera drones in civil aviation airspace. Ledwaba said unmanned aircraft systems were relatively new in the civil aviation framework and that the SACAA and other regulators across the world were working to understand, define and integrate UAVs into the civil aviation sector.

“There is ongoing global research in this area to overcome this deficiency,” Lebwaba said.

Cape Town Film Commission chief executive Denis Lillie said the industry was concerned about the ban’s impact on the economy and job creation. Two filming permits had already been refused for shoots in Cape Town in recent weeks.

While companies apply to the city for filming permits, the city sends the application to the SACAA for approval when the use of drones is indicated.

“Clearly there are significant implications for the film industry. We have already had concern from a producer who did a nature documentary in Cape Town which airs internationally,” Lillie said.

He said they have been talking to the SACAA, the transport ministry and the city about the ban and how to regulate the use of the drones. Lillie said the process of developing guidelines for the use of the drones could only be finalised by the end of the year.

In the meantime they have asked that the SACAA adopt the policy for model aircraft and apply it to camera drones. This will mean putting restrictions in place such as, flying only under 120m, no flying within 4.2 nautical miles of an airport, no autopilot flying or night flying and no flying over public property.

“The ban will not only affect feature films but also tourism promotion agencies often look for aerial shots. South Africa runs the risk of losing production activities to other areas who approve the use of drones,” Lillie said.

Acting mayoral committee member for events, tourism and marketing Ian Neilson said the city was concerned about the ban. He said the city was not averse to the use of UAVs for filming, but all necessary approvals need to be in place. “The city’s disaster risk management centre is in contact with and awaiting direction from SACAA.”

Thanks to Edge Research Lab for the HackHD







We're obliged to the chaps at Edge Research Lab for sending over a HackHD camera for use on our Low Orbit Helium Assisted Navigator (LOHAN) mission. We haven't got it into the air yet for a test, but the guys at Edge have used it for various flights and say it works perfectly. Let's face it, it must be better than our stroppy GoPro 3. More here.

100KM Challenge

100KM Challenge

 


Graham, Myself and the pilot Ryan after the successful 100+ KM flight



It seems to fly for a distance of 100 KM with our electric air plane equip with APM or so is a norm now a day. Someone even suggest to rise the bench mark to 150 KM as the entry level for long range challenge.

A few months ago, I gave it a try with my Skywalker carry 2 piece 6S 5000 mah battery in parallel. It travelled some 80 km before the ESC cut because of low voltage protection. Although the attempt was fail, but I learn some lessons. The first lesson was, it is not as easy as I think.

Skywalker is a little draggy by design, facing a strong head winds, sometimes it's ground speed will drop to a few KM per hour. It is struggling in windy condition and unfortunately, this is the condition where we usually have to deal with in tropical area. With the two big and heavy battery in the fuselage, it is also very difficult to find space for our mapping camera. But don't get me wrong, Skywalker, especially the 2014 version is a very capable air frame for what I consider mid range ( 20 to 30 KM ) mission.





Recently I read quite a number of good report of the Zeta Science FX 79. Being a flying wing design, it has a lot of space for battery AND my on board equipment. The removable wing also make this huge wing ( 2 meter wings span ) become very easy to transport.

For this 100 KM challenge, my set up is :

Zeta Science FX79
APM 2.6 external compass
3.02 firmware
Analog air speed sensor
2 pieces 6S 5000 mah battery in parallel
T motor 3110-470
APC 12 x 8
CC Edge 50 A
attopilot current sensor
CC 10A BEC
Savox 257 servo
3DR 433 telemetry.
Futaba 10C radio system
All up weight : 3.4 KG




I start the flight in the afternoon in windy condition. According to APM, the winds blow at 10 to 30 KM per hour in east or north east direction. It is certainly not a favourable condition to go for the badge but I would like simulate the actual flying condition for our usual mission.

Launching a big and heavy wings need a little caution, I wear a welder grove to protect my hand from the hungry rear propeller. With my power set up, take off is quite easy with a little head winds. After some minor trim and it start the mission.

The flight path was planned along our local Sandakan Turf Club race track. The distance of the track is 1.4 KM. This will be easier for me to confirm the total distance after the flight. I also plan it to fly at 100 meter hoping for calmer condition at lower altitude.

APM 2.6 and the latest 3.02 firmware was rock solid throughout the whole flight. After 78 rounds and the battery voltage drop to below 20 volt, I terminate the mission. After some simple calculation, it was 109 KM and APM show slightly more. The whole flight duration was one hour and 57 minutes.

My next target now is 150 KM WITH reasonable extra payload. After all, no point for us to fly for hours and come back empty handed.



I would like to thank Prof LianPin Khoo, Prof Serge Wich, Simon and Brenden of conservationdrones for their encouragement and technical advise. I also want to thank Graham who came all the way from Medan, Indonesia to have a great time flying together and tune up his conservationdrones Maja. He make the two long hours a lot of fun. Special thanks to the Arduplane development team lead by Andrew Tridge. Without all their hard work, we are still confine to fly a few hundred meter from us for fun. Thanks guys.
