From Queensland University of Technology:

Queensland University of Technology and the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia’s national science agency, have announced their next international unmanned aircraft challenge, UAV Challenge Medical Express 2016.

The previous UAV Challenge, held in 2014, tasked entrants with designing and creating an UAV that could deliver an emergency package to a hiker lost in the outback.

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 will take place in September 2016 in Outback Queensland, Australia.

    @Laser Developer,

    Interesting, thanks! Will the new high rate lidar give both distance and signal strength, or just distance? I'm wondering if we can infer anything about the material it is reflecting off from the data.

    Cheers, Tridge

    If Outback Joe is wearing a reflective jacket like on previous occasions, the laser signature is extremely strong.

    The reason is that the reflective material is actually what is known as a "retro-reflector", meaning that it has the crazy property of sending any light that hits it, straight back to the source with very little attenuation, irrespective of the angle that the light comes from. This is the same stuff used on road signs and is mostly made by 3M.

    The silver looking strips on the yellow jacket are usually "diamond grade" material and to the human eye or a camera they don't have any special properties because the eye and camera don't actually transmit any light. Instead they are relying on light from the sun to illuminate the strips and, guess what, the sunlight is being reflected back to the sun.

    So you absolutely need to have an active light source before the strips really light up. A few years back we ran some tests on the same material using a laser and were easily able to pick up the reflective signature from several kilometers away. This gives you some idea of how reflective it really is!

    Just saying...

    Wouldn't be surprised if they  add some tricky obstacle detection challenge. From an ardupilot point of view, I (selfishly) hope Canberra goes for a tilt-rotor solution! :)

  • Tridge, Rob,

    Or do a big coax X8,  similar to this, and you're pretty much done.

    18 minutes, 7kg payload: https://www.youtube.com/watch?v=Nm0ChGJ-xYU 

    20km? No problem.

    Hi Rob

    I read somewhere that your 600 size electric heli can run for about 40 minutes, is there any detail info regarding this project. It use variable pitch direct tail drive, where can I get those require components ? 

    I am asking because I would like to develop a Pixhawk power electric traditional heli for our conservationdrones. We always having problem to find proper landing site for air plane base UAV in tropical forest. 

    For your beautiful gas power heli, what is the endurance ?

    Thanks

    we won't know what the most difficult aspects of the challenge are till the rules are released.

  • Is the most complicated aspect of this challenge going to be obstacle detection on landing? Though reading th e media release it states 'joe' will be in a clearing?

  • Developer

    the big potential advantage of trad heli is precision landing in wind. The various hybrid systems (including googles wing) are more prone to wind when hovering. A heli can handle very high wind and even gusts and still fly quite precisely.

  • I'd be really interested in doing this challenge myself, but the advanced programming side is beyond me.  If there are any other computer science people near Toronto, drop me a note. :)

  • Project Wing from Google may work here. It takes off vertically, can hover in place, but is essentially a flying wing. https://www.youtube.com/watch?v=cRTNvWcx9Oo
