Canberra UAV team of 2018 Medical Express Challenge

The Canberra UAV Challenge team have published their debrief blog from the recent Medical Express Challenge. The team has gone into considerable detail in explaining their time at the event in Dalby. You can read their full account here.

We encourage all teams to share their findings from the UAV Challenge and we will promote in a similar way.

It is by sharing that we can all help achieve the UAV Challenge’s goals:

The goal of the UAV Challenge is to demonstrate the utility of Unmanned Airborne Vehicles (UAVs) for civilian applications, particularly in those applications that will save the lives of people in the future. We do this by harnessing the ingenuity and passion of aero modellers, university students and high-school students around the world to develop novel and cost-effective solutions.

Thanks Canberra UAV.

Day 5 of UAV Challenge 2018 – no overall winner in Medical Express

The UAV Challenge 2018 is over and we have had a spectacular week in Dalby. Eleven teams flew in the Medical Express Challenge. Their mission was to retrieve a blood sample from Outback Joe at his farm and in doing that they had to land within 10m of a visual target. Their aircraft had to fly at least 12 nautical miles from the Base of operations to Joe’s farm, and back (24 nautical miles in total, which is approximately 44.5km). The team to complete that mission (as per the rules) and score the most points would win $25,000. Teams had an option to complete the mission fully autonomously and show a complete hands off operation, and if they were the winning team, they would get an additional $25,000. Finally, teams had a second option to avoid Dynamic No Fly Zones in the DST Group Extension Autonomy Challenge. If the winning team also completed that, they would be awarded another $25,000. A maximum of $75,000 for one team was up for grabs!

But after three days of flying, the task proved just out of the reach of all eleven teams and unfortunately, there was no overall winner. No team successfully completed the Medical Express Challenge core mission, although two teams came very close.

The day began with just two teams left to attempt their mission flight. First up was High Flyers from Poland. They had elected to go to the back of the flight running order earlier in the week so they could sort out some issues with their aircraft. They told the judges and scrutineers this morning that they would not be capable of attempting the full mission and so instead would perform a simple mission that showed an autonomous take-off, a short flight and then an autonomous landing. They set up, put their aircraft out onto the field and it did exactly as they said it would – took off, flew a little and then landed – all fully autonomously. It was a shame that High Flyers did not manage to send their aircraft down the range, but it is wonderful to see that they knew exactly what they could and could not do and hence did not put the aircraft into a risky position.

JetStream

JetStream’s aircraft returning to The Base for a landing (left) and some of the team just after a successful autonomous landing (right).

The final team to fly in the Medical Express event was JetStream, also from Poland. JetStream had been scheduled to fly earlier but had a technical issue and elected to fly last. Like the High Flyers before them, JetStream reported to the judges and scrutineers that they would not be attempting the full mission as their aircraft appeared to have a problem with its telemetry link and so only a flight of a few kilometers distance would be achievable. The team asked if the range marshals could place their Joe target out on the range a few kilometres from The Base and they would aim to perform an autonomous take-off, fly to the target, turn around and return, finishing off with an autonomous landing. The plan was agreed as it would not change any of the scoring of points  and the aircraft would not land at the target or report its location. The team’s set up was very professional, the take-off was fully autonomous, even if it was slightly wobbly! The aircraft headed down range to the (now close) target. It turned around, flew back to The Base and performed an autonomous landing. And that was it! A successful, very short modified mission. That was the final flight of the Medical Express event and the judges retreated to their judges’ caravan to thoroughly check through all of the scoring.

No team had successfully completed the main mission. All Medical Express fans will know why, but for those of you reading this that don’t, here is the list of criteria for a complete mission (from the Rules, Version 3):

The mission is deemed complete if all of the following criteria are achieved:

  • An aircraft does not cross a Geofence boundary.
  • An aircraft lands autonomously (no-remote control) within 10m of the Emergency-Landing Target.
  • An aircraft takes off autonomously from the Remote Landing Point with the Sample.
  • An aircraft lands at the Base carrying the intact Sample.
  • All aircraft launched, land back at the Base intact within the allocated mission time.

The top two teams on points were Monash UAS and Team Dhaksha. Both teams were superb. In the case of Monash UAS, even though they successfully landed within 10m of the Emergency-Target, they had an issue that meant that they had to command their aircraft to take-off from the farm and hence the take-off could not be deemed autonomous.  The aim of this mission is that Outback Joe would be able to initiate the take-off and he could not. In the case of Team Dhaksha, they did not land within 10m of the Emergency-Landing target. Their aircraft landed over 30m away, in the next paddock and on the other side of a fence. But both teams did achieve amazing mission flights and are congratulated on these fantastic achievements.

scores

The final scores and ranking for the teams was as follows, noting that 55 teams entered the Medical Express Challenge 2018 and so the 11th ranked team, Forward Robotics, is ranked 11th from 55, i.e. a top 20% finisher! Well done to all the teams.

ME-scores-final

There was very little between the top two teams. Team Dhaksha had the higher flight segment score, but Monash UAS had a higher scoring Report and Team Interview. This was the tightest UAV Challenge result we have had for the adult competition since the first contest in 2007.

Version 2

First ranked team, Monash UAS.

The Insitu Pacific Airmanship Award went to Griffin UAV for their professionalism, attitude and decision making abilities. Airmanship is a very important part of the UAV Challenge and the judges were impressed by a number of teams.

Finally, Canberra UAV were awarded an incentive award for the team performing best in the DST Group Extension Autonomy Challenge. Not only did their aircraft travel nearly the entire length of the course avoiding virtual dynamic obstacles, but Canberra UAV also shared all of their computer code with other teams. Their attitude to sharing everything and progressing the field of low-cost UAVs for civilian applications is commendable.

This year our Gold Sponsors were the Queensland Government, Boeing, Insitu Pacific, Northrop Grumman, Lockheed Martin and Defence Science and Technology Group, and our Bronze Sponsor was The Mathworks. The event was co-organised by Queensland University of Technology (The Australian Centre for Robotic Vision) and CSIRO’s Data61. We could not run these events without this generous support and also the volunteer support of many others who commit many hours of their time to the UAV Challenge. We thank you all.

The goal of the UAV Challenge is to demonstrate the utility of Unmanned Airborne Vehicles (UAVs) for civilian applications, particularly in those applications that will save the lives of people in the future. We do this by harnessing the ingenuity and passion of aero modellers, university students and high-school students around the world to develop novel and cost-effective solutions.

We will now review how everything went this year and consider how the UAV Challenge moves forward. Stay tuned for details of the next events.

And remember this: Build. Fly. Rescue. Repeat.

Day 4 of the UAV Challenge 2018

Did we say that yesterday at the UAV Challenge was good? Well today may have been even more amazing. Today was the day when we aimed to let at least five teams fly their missions in the 2018 Medical Express Challenge. In the end, six teams flew.

MelAvio-summary

First to fly today were MelAvio Avionics Club from Poland. Their impressive looking aircraft was brought out onto the field only for the team to have to take it back undercover due to a sudden deterioration in the weather. We had a 30 minute weather hold and started again. After the restart, MelAvio began their engine testing only to find that there were issues with the running of the main petrol engine (used for the forward flight portion of their mission). They worked bravely for over half an hour to try and fix the issue and finally launched their aircraft into the air. But it soon became apparent to them that there were still issues with the engine and they decided to call it and land and not continue. This was a great piece of airmanship. Safety first!

FWD-summary

Forward Robotics used two planes for their mission attempt (left) but had issues with both (right).

Next up was Forward Robotics from Canada. They were returning from 2016 when they first showed off their amazing looking aircraft. They had two years of updates and practice and were another hot favourite to complete the mission. The first aircraft took off well and headed down range. But the second aircraft had an issue immediately after take off and did not head into the range. The team decided to abort the mission and manually land the second aircraft. The first aircraft then landed outside of the Base area due to a technical issue and their mission was over.

ISAAC-sumamry

ISAAC UAV completing pre-flight checks (left) managed a short flight (right) before having to abort the mission.

The third team for the day was ISAAC UAV from Thailand. They brought a helicopter to the last Medical Express event in 2016 but this year decided to use a quadplane. They seemed extremely well prepared (as they were in 2016). Their set up took a little bit longer than they hoped and they used up some of their 60 minute mission time completely all their final checks. The aircraft performed a take off and headed off down the range but a loss of one of their communication links meant that the aircraft’s return to home behaviour kicked in. The aircraft flew straight back to the Base and was manually landed by the safety pilot. The team tried again but they encountered another issue that meant the aircraft took off but then simply hovered. They aborted the mission and their UAV Challenge was at an end.

MAVLab-summary.jpg

MAVLab TUDelft, from The Netherlands, were up next and they decided to use an elevated work platform to extend their antenna height and hence communication range. The work platform was parked next to the ground station area and held the team’s main radio antenna. They also had an Iridium (satellite) link. The set up went smoothly and the take off seemed very straight forward. The team even brought some lunch to have while waiting for their aircraft to complete the mission. A technical issue with the GPS location feed they were supplying to the judges meant that the Dynamic No Fly Zone part of the competition could not be fully completed, although the aircraft was seen to be avoiding obstacles as it transited past the Base. Once at the farm, the aircraft automatically detected Joe’s target and initiated its landing sequence. Then disaster struck! As it slowly descended the main rotor switched off prematurely, roughly 1.5m above the ground, and the aircraft fell to the ground with the impact breaking the wing structure. The judges and scrutineers at the farm immediately declared that the aircraft was not fit to take off again (they saw the wing bent 45 degrees before they made it safe) and so the mission was over.

GriffinUAV-summary

The number five team for Thursday were Griffin UAV from Thailand. This was there first UAV Challenge event and it was clear to the judges from the way the team walked onto the field that they were professional but also determined to enjoy their mission time. They had a single aircraft attempting the mission and their set up and pre-flight checks went well. The aircraft was cleared for take off and immediately headed to Waypoint 1 at the south of the range. All systems appeared to be operating normally and the aircraft came back towards the Base, swung around (as it is supposed to do) and headed off to Outback Joe’s farm. The mission up to this point was fully autonomous. The judges and scrutineers at the farm reported the aircraft’s successful arrival overhead. At this point the aircraft itself or the team (it is not clear as we write this) decided that there was not enough battery life to perform a remote landing and subsequent take off and get back to the Base to complete the mission. So instead the aircraft took some photos of the farm and returned directly to the Base without Outback Joe’s blood sample. The aircraft landed properly at the Base, delighting the team and the crowd that they still had a fully functioning aircraft. Griffin UAV had a lot to be proud of.

TeamDhaksha-summary

At this point in the day, the team JetStream from Poland elected to go to the end of the flight queue and that made Team Dhaksha from India next. They were given their 15 minute warning to get ready and starting organising. This team has two very unusual hybrid multirotor aircraft. Each have a petrol engine that power a generator for the electric motors. They report flight times for these aircraft at between 3 and 4 hours! The crowd was very eager to see how they performed. Team Dhaksha elected not to compete for the Extension Autonomy Challenge but instead focussed on completing the mission full autonomously. Both aircraft took off autonomously. The retrieval aircraft headed off down the range and the support communications relay aircraft parked itself about 30m above and to the side of the flying field, where it remained for the rest of the mission. The mission proceeded in a complete hands off fashion. The retrieval aircraft completed the first leg, swung around the Base and headed to the farm.

On arrival at the farm it began searching for Outback Joe’s target and reported that it had done so and that it had initiated a landing. The judges and scrutineers confirmed that it appeared to be landing in a safe location and so the aircraft was left to complete its landing. But it then became clear that it was well away from the 10m distance from the target that it needed to be for Team Dhaksha to officially complete the mission. The aircraft landed 35.6m away in the next field to where the target was lying.  The scrutineer at the farm placed Outack Joe’s blood sample in the landed aircraft and pushed the arm button. Sixty seconds later, the aircraft autonomously took to the air and headed back the way it had come. Both aircraft successfully landed autonomously after the retrieval aircraft completed the full mission distance (approximately 24 nautical miles). The mission was over and full autonomy had been used throughout. Even though the mission was not successfully completed due to the 10m rule, it was a remarkable achievement. Hats off to Team Dhaksha!

Autonomous flight – check! Autonomosu take-off and landing – check! Outback Joe’s blood sample – check! The Dhaksha approaching their returned retrieval aircraft.

We have just two more teams to fly tomorrow. They are the High Flyers and JetStream, both teams are from Poland. Friday maybe another epic day at the UAV Challenge. We certainly hope so. Stay tuned…

 

Day 3 of UAV Challenge Week 2018

SkyHigh

One of Sky High’s winning drops in the Airborne Delivery Challenge.

What a great day! Day 3 of the UAV Challenge week was a fantastic success. The first few hours were devoted to the high-school student teams competing in the Airborne Delivery Challenge. You can find a full summary of that competition here. The winning team was Sky High from William J. “Pete” Knight High School in Palmdale California.

Version 2

The two blood samples from Outback Joe that were recovered at the Base after being transported by UAV from Joe’s farm.

The remainder of the day was dedicated to the first mission flights of Medical Express teams. The weather was ideal and we hoped that three teams would get to fly and complete their missions. By the end of the day we did indeed see Monash UAS, Canberra UAV and West Coast UAV all fly their missions.

MonashUAS

UAV ahoy (left) and the blood sample removed from Monash UAS’s retrieval aircraft at the end of the mission flight (right).

First up in the Medical Express Challenge were Monash UAS. Their very large team were highly organised and started off extremely well. Their two aircraft took off autonomously and both headed down the range. The communications relay aircraft stayed close to Waypoint 1 for the rest of the mission while the retrieval aircraft flew to Outback Joe’s farm. Impressively, the aircraft automatically found the target that had been put out by Outback Joe and landed just 5.6m from it. Until that point, the team had run the mission totally hands-free. But a problem was spotted by the team that meant that the landed aircraft could not be reactivated by Outback Joe at the farm (as per the rules) and so the team intervened and commanded the aircraft to take-off and return to the Base. Both aircraft came into land fully autonomously and the blood sample was successfully transport from the farm to the Base. This was a great effort by the team but they did not complete the mission.

CanberraUAV

The second team to fly was Canberra UAV. They had come first in the last competition in 2016 and are one of the favourites to complete the mission this year. This year, the Challenge is tougher than it was in 2016 as the organisers have added an optional Extension Autonomy Challenge – sponsored by Defence Science and Technology Group. Canberra UAV elected to tackle this extra challenge which involves their aircraft having to re-plan its route live while it encounters up to 32 virtual dynamic flying obstacles such as other aircraft, bad weather or birds. These obstacles are known as Dynamic No Fly Zones and they are fed into the UAV’s ground station as a simulated radar feed.

The mission for Canberra UAV started with an issue relating to the tuning of the petrol engine of their retrieval aircraft. After some troubleshooting, the team managed to fix the issue and start their mission flight. But they had used some of their 60 minutes of mission time to fix their issue. The team was really up against the clock. The retrieval aircraft made fantastic progress to the farm while the communications relay aircraft remained on station close to the Base. On route to the farm, the team reported a technical issue onboard the retrieval aircraft that resulted in an inability to geo-reference the images of Outback Joe’s target. Canberra UAV’s Andrew (Tridge) worked to fix the issue but in the end manually geo-referenced the target location, and the aircraft landed over 20m from the target. This meant that the team could not complete the mission as a team must land its aircraft within 10m of the target to qualify for a completed mission.  The judges at the farm loaded the blood sample int the aircraft and reactivated it, allowing it to autonomously take-off and return to the Base. Both Canberra UAV completed autonomous landings.

What did go right for Canberra UAV was their ability to successfully re-plan their flight and avoid the Dynamic No Fly Zones. Their aircraft navigated all things thrown at them in an incredible performance that impressed the judges. Even though Canberra UAV did not complete the mission, they did show that it is possible to autonomously navigate in extremely challenging environments.

WestCoast

The final team that got to fly today was West Coast UAV. The team had modified their system from the one they entered in 2016 competition by launching both aircraft autonomously from a catapult launcher. The team’s aircraft flew in formation down to Waypoint 1 and back to the Base before heading towards the farm. Up until that point of the mission, the operation was totally hands-off. Then disaster struck. The retrieval had some sort of technical failure and came down in the range. The team decided to let their imaging aircraft continue to the farm to hunt for the target. Unfortunately that aircraft did not find the target and was commanded to fly back to the Base. On the way the team realised that they could use their aircraft to search for their missing retrieval aircraft and so a search began around its last known location. In the end, that search did not find the aircraft and the imaging aircraft was commanded back to the Base where it performed an autonomous landing.

The flying order for tomorrow is as follows:

MelAvio Avionics Club
Forward Robotics
ISAAC UAV
MAVlab TUDelft
Griffin UAV
JetStream
Team Dhaksha

with the High Flyers electing to fly at the end. Note that as High Flyers have been given an opportunity to fly but have elected to move the the back of the queue, an additional day of flying (Saturday) will not be activated for them if they do not get an opportunity to fly by the end of Friday.

Tomorrow will be another very big day for the UAV Challenge and the organisers wish all the teams the best of luck.

 

Team Sky High win the 2018 Queensland Government Airborne Delivery Challenge

First-Second

Winners Sky High (left) and Second Place Blue Birds (right) receiving their certificates and trophies from Rita Borzelleca from the Queensland Government.

Day 3 of UAV Challenge Week saw the completion of the Queensland Government Airborne Delivery Challenge. The event was partially delayed yesterday due to bad weather but today was a beautiful day, from start to finish. The last six teams down the running order took to the field at 7.30am in ideal conditions. In the end it was quite a close contest.

The winner (and also best Rookie Team) was Sky High from William J. “Pete” Knight High School in Palmdale California. The secret of their success was three great drops. Their accuracy was fantastic and they achieved drops of 3.62m, 0.18m and 1.04m. One of those drops was gentle enough not to exceed the impact limit and that was enough to put them first place.

Second place went to Blue Birds, also from William J. “Pete” Knight High School. They also did three accurate drops, though all of them impacted above the 75G “survival” limit.

third

Third place team, PHS Falcons (left) and the Insitu Pacific Airmanship Award winners, the Millennium Falcons receiving their award from Brendan Williams from Boeing (right).

In third place was PH Falcons from Palmdale High School in California. Their best drop was 0.4m.

The Insitu Pacific Airmanship Award was given to the Millennium Falcons for their professionalism and great team attitude.

AD-scores-final

The final scores of the 2018 Queensland Government Airborne Delivery Challenge

The organisers were impressed by the teams that did not score so well but used automatic dropping systems. It is great to see high-school teams implementing these systems and we are sure that these will improve in the future.

Team photos will be posted in the coming weeks. The organisers would like to thank the teams for the great spirit in which they competed and the event sponsors for their continued support.

This year our Gold Sponsors were the Queensland Government, Boeing, Insitu Pacific, Northrop Grumman, Lockheed Martin and Defence Science and Technology Group, and our Bronze Sponsor was The Mathworks. The event was co-organised by Queensland University of Technology (The Australian Centre for Robotic Vision) and CSIRO’s Data61.

We could not run these events without this generous support and also the volunteer support of many others who commit many hours of their time to the UAV Challenge.

Day 2 of UAV Challenge Week 2018

Day2-1

A windy overnight “flying” incident (left), the team currently known as {insert_team_name_here} take to the field (right).

We all had a huge day out at Dalby Model Aero Club today. There was wind, rain, lightning and some great flying by our high-school teams. We always knew that Day 2 would be a complicated day. The day was planned as the flying day for the Airborne Delivery Challenge and the scrutineering day for the Medical Express Challenge.

Teams and organisers arrived to find that the overnight wind had done a bit of damage to the small tents we use to shield the competitors and judges. The wind conditions were above the limit set out in the Airborne Delivery rules and so the high-school teams had to wait until mid-morning when the wind finally dropped and they could fly.

Day2-2

MUROC Titans doing their pre-flight checks (left), Precision Air with super star Outback Joe (right).

First up were {insert_team_name_here}, High Flyers and Dickson sUAVé. All of them did a great job considering the long wind delay. It was great to see some auto dropping of the Impact Monitor to Outback Joe. MUROC Titans were up next but their flight was interrupted by rain and the competition was paused for nearly three hours while the Dalby region got a well-needed soaking (7mm). The Titans started again after the delay and managed three drops using a novel winch-like delivery mechanism. The team from Aragon High School in California came out next, followed by Precision Air from Noosa District High School. And then the wind returned. We called it a day and will be back to fly the remaining six teams first thing in the morning (Southwest Aircorp, Team Hybrid, Millennium Falcons, PHS Falcons, Sky High and Blue Birds).

Day2-3

Team Dhaksha from India (left) and the judges interviewing High Flyers – Academic Scientific Association team (right)

In the Medical Express Challenge, the teams arrived and set up their aircraft ready for scrutineering and their interview with the judges. We have eleven teams competing this year and all have now arrived. The scrutineers and judges had a very long but productive day checking the UAVs and quizzing the teams to ensure that everything is ready to go for the flights over the next few days. This is the first year that the UAV Challenge Medical Express event is operating officially as a Beyond Visual Line Of Sight (BVLOS) operation.

The running order for the Medical Express teams is:

Monash UAS
High Flyers
Canberra UAV
West Coast UAV
MelAvio Avionics Club
Forward Robotics
ISAAC UAV
MAVlab TUDelft
Griffin UAV
JetStream
Team Dhaksha

Tomorrow we hope that the weather will be far kinder and we will complete the Airborne Delivery Challenge and start the competition flights for Medical Express. It is going to be another busy day for Outback Joe.
