Flying completed for the 2018 UAV Challenge

By | July 17, 2018

What an amazing weekend! The Kraken flew two long missions; the second of which was 1 hour and 28 minutes. This is pretty amazing for a purely electric aircraft.

The OctoPorter flew twice on Sunday, with both missions being 1 hour missions. It was a great sight to see them both tracking autonomously around their orbits around CMAC at the same time; with sensible height deconfliction of course.

With the D3 flying done, we now need to get on with testing the new Raspberry PiCam based imaging capability that Stephen has been working on very hard this year. There is also some integration and testing of the data feed for the ‘Dynamic No Fly Zone’ portion of the 2018 competition to be done. Onward and upward!

Just for fun, here is a video of the flying this weekend.

What goes up…

Life at the cutting edge can be bumpy! We were testing a new method of using small flight controllers in each wing to improve data management, give us the ability to monitor the ESCs in flight and reduce wiring. We have also fitted new BLHeli ESCs to the vertical lift motors, which give us the ability to output the monitoring data that we need.
The OctoPorter flew well in the first two flights of the day in very low altitude hovers while we checked loiter and basic hovering. We pushed it up to 5 meters for our third test hover of the day.
This picture speaks for itself!

Our follow up investigation shows that the ESCs clearly ceased functioning properly at almost the same exact time, but we’re still trying to figure out why. Neither of them is working now, and they both show the same symptom of not booting and just getting really hot, focussed on the Microprocessor.
A new starboard wing is required and another look at those ESCs. The 5hrs for the next UAV Challenge deliverable will have to wait for now…

Deliverable 2 for the 2018 UAV Challenge has been submitted!

By | April 10, 2018

We’re very excited that our second deliverable for the 2018 UAV Challenge has been submitted. Just a few stressful weeks until we receive our Go/No-Go from the organisers.


In the mean time, we have got lots of work to do. In particular we need to make some technological improvements to our OctoPorter to improve it’s reliability and refine the build of the Kraken.

We’ve also got work to do on our autonomous target location based on our new Raspberry Pi based automated image recognition software and development of the ArduPilot code to deal with Dynamic No Fly Zones. Watch this space for updates!

We’ll keep you updated as we go. Thank you very much to our family, friends and supporters! Don’t forget that we really appreciate donations to our Patreon account to help us fund our project. We put all of our work straight back into the ArduPilot community and make our autonomous image recognition software available to all; please consider contributing if you get use or pleasure out of this like we do!

CanberraUAV OctoPorter Flight – 30 March 2018

By | March 31, 2018

Yesterday we enjoyed a beautiful Canberra morning flying the OctoPorter. We did thorough ground checks and some manual take-off / landing cycles before a full auto mission. The landing from the auto-mission is in this video; what an amazing sight and sound! We are excited to have the opportunity to make a number of software and hardware upgrades to the aircraft to make it more reliable and capable for the UAV Challenge this year.

We aborted a mission on Sunday before it had even started; here’s why

CanberraUAV prides itself in being a responsible civilian not-for-profit organisation; a key part of this is conducting our flying activities in a safe manner. We understand the responsibility that we have as members of the aviation community; in the spirit of that community it is important that we talk about the safety aspects of our hobby. We aborted a mission on Sunday before it had even started; here’s why

A number of flight safety ‘human factors’ began to line-up during our usual Sunday flying period at our home field. Time became compressed due to availability of key members. Due to some technical development activity, the mission was delayed until around 1130 and a significant ‘rush’ to get airborne was felt within a final 20 minute availability window. By this time heat was fairly extreme on the field (37℃+).

A number of failures were experienced whilst setting up the bungee cord which was then modified ‘on the fly’ and was to be connected to a bungee launch mechanism that had not been tested on a live launch. Our ‘spider senses’ told us that we were about to push our luck. Only a minute or two until the launch, the group ‘called it’ and cancelled the mission before any launches were attempted.

It is good practice to maintain perspective on the situation when you fly. In this case it really wasn’t crucial to conduct that mission at that time and too many things hadn’t gone quite as planned in the preparation. Flight Safety experts talk about the holes lining up in the ‘swiss cheese’; those ‘holes’ are all individual events. When those ‘holes’ line up, or happen together, that can amount to enough issues to cause an accident. At the bleeding edge of open source UAV development accidents do sometimes happen, but we don’t just accept that crashing is ‘normal’ when we don’t need to.  In this case a rushed launch could have caused a heavily damaged airframe. That would have cost money and put back imagery data collection efforts causing longer term issues for our UAV Challenge project. This way, the Opterra lives to collect another day!

Happy New Year to you aviators, innovators, supporters and educators!

Before we have even started with all of our activities in 2018 we need to say a big thank you to our outgoing Canberra UAV President, Stephen Dade. He has done an incredible job of steering Canberra UAV to success from the beginning through the 2012, 2014 and 2016 UAV Challenges. He has been the master of the unseen organisational activity that underpins Canberra UAV, along with being an exceptional contributor to our software in his own right. Stephen is stepping aside as the President of the club to let ‘new blood’ have an opportunity on the Committee.
The new Canberra UAV President is Jimmy Owens; Jimmy just really hopes that he isn’t the first President of Canberra UAV to make a mess of the UAV Challenge entry!
2018 is going to be a big year for us, with the changes to the UAV Challenge Medical Express rules challenging us to really push our technology forward. We’re hard at work trying to develop some pretty big things for the 2018 UAV Challenge. Because the rules have changed we need to make some significant changes to our imaging hardware and software. We love our Quad-Porter, but we are working hard on developing an entirely new type of aircraft, a Thrust Vectored Belly Sitter. If we can get this to work, we will be able to combine the take off and landing advantages of a ‘copter with the efficiencies of a mechanically and electrically straight forward fixed wing aircraft; that is not only useful for the challenge but for numerous real world applications.
