Medical Express Challenge

The Medical Express Challenge is the current event that is open to all. It was first held between 2015 and 2016 with the first event held in Dalby, Queensland, Australia in September 2016. The current Medical Express runs from 2017 to 2018 with the event again being held in Dalby. The challenge itself is for teams to develop a solution to the problem of remote medical retrieval. Teams have to fly their aircraft at least 20 km to a remote farm, detect the farmer Outback Joe and autonomously land close by. The farmer places a medical sample into the aircraft and it must then return to the original launch point which is at least 20 km away. The challenge was very nearly completed at the first attempt by a team from Canberra, Australia called Canberra UAV. Their communications relay aircraft crashed at the remote farm site due to an engine failure and the challenge was hence not completed. But their main aircraft did successfully return the medical sample from the farm.

Search and Rescue Challenge

The Search and Rescue Challenge was held from 2011 to 2014. It was open to worldwide participation, including by universities and hobbyists. In the challenge, teams must find a target dummy, called Outback Joe and accurately deliver an emergency package to him. The backstory of Joe is that he is a bushwalker that has gotten lost, or a worker who's ute has broken down. He is represented by a 50 kg mannequin dressed in jeans, a work shirt, work boots and an Akubra. The mission area is nearly 2 kilometres (1.2 mi) from the airport and is approximately 4 kilometres (2.5 mi) x 6 kilometres (3.7 mi). Teams must not fly greater than 1500 ft above ground level (AGL). Under the rules, teams were required to firstly identify the latitude and longitude of the target to within 100 meters. Teams that succeeded in this task were permitted to attempt to drop the package and complete the challenge.

Outback Joe was first spotted in 2010 by the University of North Dakota team. In 2012, the Canberra UAV team's aircraft automatically located the target the first fully automatic detection during all events. In 2014, 5 teams correctly identified the target location allowing them to drop a package to him. The winner of the challenge was CanberraUAV, who dropped a water bottle to within 2.6 metres of the target.

Airborne Delivery Challenge

The Airborne delivery challenge is open to Australian high school students. The objective is to create a future generation of aerospace professionals with a focus on UAVs.

An airframe has to be built and the mission is executed by two persons who will not communicate during the mission and will have technological targeting solutions in place:

• UAV Controller in charge of piloting the airframe (or programming the mission in case of the Robotic challenge)
• Mission manager in charge of the mission package drop

Other team members are permitted and many teams have roles for a team manager, media manager and safety manager.

In 2009 and 2010 a Robot Airborne Delivery Challenge was also held in parallel to the main Airborne Delivery Challenge. The Robot competition was dropped in 2011 in favor of bonus points for autonomous payload dropping in the Airborne Delivery Challenge.

2007 competition

The first event was held between September 24 and 27.^[5] It attracted interest from 43 teams from 6 countries^[6] of whom 20 submitted full entries. No teams passed flight scrutineering although Team Dionysus from the USA did demonstrate some autonomous flight at the airport. MUROC I, a high school team from Mueller College, won the inaugural Payload Delivery Challenge.

In 2007 the UAV Challenge was organised by the Australian Research Centre for Aerospace Automation (a five-year-long partnership between CSIRO and Queensland University of Technology), the Queensland State Government, and Boeing Defence Australia.

2008 competition

The 2008 UAV Outback Challenge was held between September 22 and 24 and had a combined prize fund of A$70,000.^[7] The prize for completing the Search and Rescue Challenge was increased to A$50,000. 51 teams from 8 different countries expressed an interest in entering with 17 finally qualifying for the event. As in 2007, teams failed to complete the Search and Rescue mission, with only Team Telemasters and Missouri S&T UAV teams passing the stringent flight scrutineering to begin the S & R Mission. Missouri S&T crashed on takeoff, and Team Telemasters aborted shortly after takeoff. No flights left the airport for the search area.

In 2008 the UAV Challenge was organised by the Australian Research Centre for Aerospace Automation (a five-year-long partnership between CSIRO and Queensland University of Technology), the Queensland State Government, and Boeing Defence Australia.

2009 competition

The 2009 UAV Challenge was announced in the December/January 2008 issue of Aviation Business Asia Pacific magazine. The 2009 event took place between September 28 and October 1. The combined challenge award funds were A$70,000.00. 34 Search and Rescue teams from 5 countries expressed an interest in entering with 12 finally qualifying for the event. In addition to the traditional Search and Rescue Challenge and Airborne Delivery Challenge, there was a new Robot Airborne Delivery Challenge open to high-school students. The two separate documentary challenges of the previous years were combined into a single Documentary Challenge.

2009 was the first year that teams managed to enter the search area. Team Galah suffered an engine shutdown just inside the search area and made an emergency landing less than 100 m from Outback Joe (although they were not aware of this at the time). Team Melbourne UAV were en route to the search area when high wind conditions flipped their aircraft causing it to enter flight termination mode. The airframe was lost due to high impact with the ground.^[8]

In 2009 the UAV Challenge was organised by the Australian Research Centre for Aerospace Automation (a five-year-long partnership between CSIRO and Queensland University of Technology), the Queensland State Government, and Boeing Defence Australia.

2010 competition

The 2010 UAV Challenge took place between September 27 and 29. In the Search and Rescue competition a team from the University of North Dakota became the first in UAV Challenge history to successfully locate Outback Joe, managing to pinpoint his location to within 15 m (from 800 ft AGL).^[9] However, they failed to drop a water bottle within 100 m (as required by the rules) and hence did not win the A$50,000 prize.^[10] Team Robota, from Texas, was awarded second place after their aircraft successfully entered the search area but had to abort the mission due to a technical issue.^[11] A total of 43 teams entered the Search and Rescue competition with 12 qualifying to fly but only six flying at the event.

In 2010 the UAV Challenge was organised by ARCAA (QUT and CSIRO), Queensland Government and Aviation Development Australia Limited. It was sponsored by Insitu, CASA, Australian Defence Magazine, AUVS-Australia, Boeing, CAE Inc. and South Burnett Regional Council.

2011 competition (new format)

On 16 March 2011, the UAV Challenge organizers announced major changes to the format of the Challenges.^[12] Stated changes included a new longer format Search and Rescue Challenge that results in an event at Kingaroy being held every two years instead of every year (as was done from 2007 to 2010) and the development of Australian State Championships for the Airborne Delivery Challenge. The organizers were quoted as saying that they believe this will lead to "more participants competing with a very high standard of UAV capability".

For the first time, the event was not held at Kingaroy. Instead an Airborne Delivery Challenge (High-School teams) championship was held at Calvert Radio Aero Modellers Society flying field (approximately 25 kilometres (16 mi) west of Ipswich, Queensland) between September 27 and 28.^[13]

In 2011 the UAV Challenge was organised by ARCAA (QUT and CSIRO) and AUVS-Australia. It was sponsored by Queensland Government, had the assistance of Ipswich City Council, and technical staff from Boeing, UAS Pacific and Skills Queensland.

2012 competition

The 2012 event was held at Kingaroy October 1–3 and followed a similar format to the 2010 competition with both a Search and Rescue and Airborne Delivery Challenge. The 2012 Search and Rescue competition actually began in 2011 when the competition was lengthened to 18 months in duration. 2012 saw the introduction of the Search Phase as part of the Airborne Delivery Challenge competitions.

Sixty-eight teams registered for the Search and Rescue Challenge, with 53 passing the first checkpoint. Over the subsequent 18 months the field was reduced to just five, the rest having either failed to pass certain milestones or withdrawing due to technical difficulties such as crashes. At the event in Kingaroy, four teams launched their aircraft into the range. The main task was not completed by any of the teams.^[14] However, two teams did manage to complete a significant portion of their search phase and successfully returned their aircraft to the airport. Team Canberra UAV achieved automatic detection of Outback Joe - the first team to do so in the history of the event.^[15] They did not manage to drop the bottle of water due to an in-flight incident prior to the Outback Joe detection when it appeared that the water bottle became loose from the aircraft and fell off.

Thirteen teams competed in the Airborne Delivery Challenge with a winner declared for its Search Phase.^[16] The Airmanship Award was sponsored by Insitu Pacific and was awarded to Nina Clark for her outstanding team leadership.

In 2012 the UAV Challenge was organised by ARCAA (QUT and CSIRO), AUVS-Australia and Aviation Development Australia Limited. It was sponsored by Insitu Pacific, Boeing, Lockheed Martin, CASA, Mathworks, Aviation Australia, Stanwell Corporation Limited and DSTO. The Challenge was also supported by the Queensland Government, South Burnett Regional Council, UAS-Pacific, the U.S. Office of Naval Research Global, the Asian Office of Aerospace Research and Development, and Australian Defence Magazine. The event also had the assistance of personnel from Raytheon, the Royal Australian Navy and the Victoria Police Air Wing.

2013 competition

2013 was a high-school only event with the international Search and Rescue Challenge starting that year but running for two years (with its own event at Kingaroy, Queensland, Australia planned for September 2014). For the second time, the Airborne Delivery Challenge (High-School teams) championship was held at Calvert Radio Aero Modellers Society flying field. The Challenge took place between September 24 and 25. The competition was very close and was notable because for the first time a high-school team (The Hexfactor for Mueller College) managed to achieve a successful autonomous drop of a chocolate bar to Outback Joe, landing within the required 10m distance to be award bonus points. Although the Hexfactor did not win the event, the fact that they succeeded with some autonomy was a milestone for the UAV Challenge.

In 2013 the UAV Challenge was organised by ARCAA (a QUT research centre) and CSIRO. It was sponsored by Insitu Pacific, Boeing, Northrop Grumman and Mathworks. The Challenge was also supported by the Queensland Government, the Australian Association for Unmanned Systems, and UAS-Pacific. The event also had the assistance of personnel from VTOL-Aerospace and Aviation Australia.

2014 competition

The 2014 event was held at Kingaroy September 22–26 and followed the same format to the 2012 competition with both a Search and Rescue and Airborne Delivery Challenge. For the first time ever, the Search and Rescue mission task was completed and the UAV Challenge Outback Rescue was won.^[17] Four teams completed the mission task with CanberraUAV winning the $50,000 prize on points.^[18] They were also awarded the Rod Walker Trophy for their win. They completed the mission with an autonomous takeoff, a bottle drop accuracy of 2.6m and a fully autonomous landing. One hundred and sixteen Search and Rescue teams registered for the event, with the field of teams being reduced to 20 after the Deliverable 3 qualifying round. Fourteen teams flew at the event and left the airport, beating the previous record of four teams. Four teams successfully completed the task of finding Outback Joe and delivering him at least 500ml of water to within 100m of his location. Team SFWA from Melbourne, Australia, were the first team in the history of the event to complete the mission.^[19] A fifth team, VAMUdeS from Canada came close to completing the mission with a drop of 116m. The Search and Rescue competition Airmanship Award was sponsored by Insitu Pacific and was awarded to Pawel Wozniak for his outstanding team leadership and decision making.

The high-school Airborne Delivery Challenge in 2014 was, for the first time, open to high-school teams from outside Australia. Fifteen teams entered and qualified to attend the event in Kingaroy. The winner of the Airborne Delivery main competition was the all-girls team the DareDivas from Mueller College, Australia. Another all-girls team, from Knight High School in California, came third. The Airborne Delivery competition Airmanship Award was sponsored by Insitu Pacific and was awarded to Russell Porter from Indooroopilly State High School.

In 2014 the UAV Challenge was organised by ARCAA (a QUT research centre) and CSIRO. It was sponsored by Insitu Pacific, Northrop Grumman, Mathworks, Boeing, CASA, Stanwell Corporation Limited and DSTO. The Challenge was also supported by the Queensland Government, South Burnett Regional Council, UAS-Pacific, and Australian Defence Magazine. The event also had the assistance of personnel from Raytheon Australia, Aviation Australia, V-TOL Aerospace and the Victoria Police Air Wing.

2015 competition

2015 was a high school-only event with the international Medical Express Challenge starting that year but running for two years (with its own event in Queensland, Australia planned for September 2016). The high-school event was held for the third time at Calvert Radio Aero Modellers Society flying field (approximately 25 kilometres (16 mi) west of Ipswich, Queensland). The event was significant in that major changes to the rules of the Airborne Delivery Challenge meant that the mission task was far more difficult for teams that it had been in previous years. For this competition, teams had to drop a medical payload without breaking it. 2015 also saw the re-introduction of a fully autonomous competition for high-school students, the Robotic Delivery Challenge. Three teams qualified, but none managed to complete the mission.^[20]

In 2015 the UAV Challenge was organised by ARCAA (a QUT research centre) and Data61 (a unit of CSIRO). It was sponsored by Insitu Pacific, Northrop Grumman, Boeing, DSTO, and LightWare. The Challenge was also supported by the Queensland Government.

2018 competition

2018 marks the return of the Medical Express Challenge for the open teams and the introduction of voluntary dynamic no-fly zones (DNFZ) to the competition. Dynamic no-fly zones represent obstacles that an UAV must avoid during its transit to the search area, which can be birds, bad weather and other aircraft. These obstacles are generated by a computer and passed onto the teams. Due to the complexity of this requirement, only a few teams attempted this aspect of the challenge, with the stand out being Canberra UAV whose avoidance performance impressed the judges.

The main goal of the competition was to fly to a designated search area and search for a target, onto which the aircraft must land vertically within 10m and retrieve a blood sample from Outback Joe, and return to the base with the sample. The competition was exceptionally close this year, with the top two teams scoring within 1% of one another. The team that has come out on top was Monash UAS, an undergraduate university team from Melbourne, Australia. Although no teams technically completed the challenge due to a variety of reasons, the top three teams were able to return the sample to the base intact.
