At long last, Outback Joe has been found.

By Emily Lehmann

Flying robot enthusiasts can breathe a deep sigh of relief, because Outback Joe has finally been saved after spending eight years lost in the bush.

This week, sixteen teams from around the world competed in the search and rescue mission to save our beloved Akubra-clad mannequin pal, who has year after year, been strategically placed in the Queensland outback as part of the Unmanned Aerial Vehicle (UAV) Challenge.

After eight years running, this was the first time that a team – not just one, but four– successfully delivered the emergency package to save Outback Joe, with the top team taking home a grand prize of $50 000.

Each team was tasked with developing their own custom-made UAV (a.k.a flying robot or drone) and navigating it through a course to first locate Outback Joe, and then secondly deliver him a life-saving bottle of water.

The competition brings some of the latest international aerial robotics technology and puts it to the test to highlight its value for use in search and rescue efforts.

These flying machines can cruise at various speeds – some are just like helicopters – and can mostly fly for 40 to 60 minutes at a time. They rely on modern computers and sensors, such as GPS, to figure out where they need to go in order to perform tasks that the operator has asked it to do.

The clever minds behind the winning ‘bot are from CanberraUAV and managed to score the most points out those that completed the challenge – two other Australian teams and one from the United States.

The UAV Challenge also involves a delivery challenge for high school teams, taking place earlier in the week. Students build their flying robots from scratch, designing and developing the software and hardware needed for their own rescue mission for Outback Joe.

This year’s winner was the all-girl DareDivas team from Mueller College at Redcliffe with a $5 000 prize.

We run the UAV Challenge annually in partnership with the Queensland University of Technology.

Bees backpacking in Brazil

How do bees in the Amazon jungle compare to those in Tasmania? They get up earlier, for a start.

Paulo de Souza and his team have been tracking bees in the two regions using tiny backpack sensors as part of our Swarm Sensing Project to gather biological and ecological data to improve honey bee health.

The tiny backpacks are just a quarter of a centimetre square and are fitted to the back of the bees.

“We have already attached the micro-sensors to the backs of thousands of bees in Tasmania and the Amazon and we’re using the same surveillance technologies to monitor what each bee is doing, giving us a new view on bees and how they interact with their environment,” Paulo said.

“Once we have captured this information, we’ll be able to model it. This will help us understand how to manage our landscapes in order to benefit insects like bees, as they play such a key role in our lives. For example, one third of the food we eat relies on bees for pollination, that’s a pretty generous free service these humble insects provide us!”

Early modelling has shown one notable difference between the bees in Tasmania and those in the Amazon; Amazon bees are up and about very early in the morning while Tassie bees prefer to wait until the day warms up before they leave the hive.

But finding out what time bees get out of bed is only a tiny part of what the research can show us. For example the research will also look at the impacts of agricultural pesticides on honey bees by monitoring insects that feed at sites with trace amounts of commonly used chemicals.


A global buzz in micro sensing

We’re working with the Vale Institute of Technology in Rio de Janeiro, Brazil, on micro-sensory technology and systems (read  more about what Vale is up to here).

Working with researchers across the globe has its unique challenges as well as its rewards, and it’s the physical challenges that have been the most interesting.

“As the Africanised honey bees were very aggressive, the hive was placed in an isolated area away from housing and domestic animals – and isolation meant working in densely vegetated areas,” Paulo explained.  “We had to clear a path to the hive and we wore fully protective bee clothing which was tough given the extreme humidity and heat.”

The Brazilian media got a taste of what it was like to work in these conditions, when they suited up to interview Paulo and our colleagues from the Vale Institute of Technology about their work

The collapse in global populations

Bee health is important globally however, honey bee populations around the world are in danger.

Colony Collapse Disorder (CCD) – a phenomenon in which worker bees from a colony abruptly disappear – and Varroa mite are two major problems facing bee populations globally. While these two problems haven’t appeared in Australia, there is a very real risk.  And what happens if it does? Catastrophe!

Check out this video where Peter Norris, Tasmanian beekeeper, describes his first hand experience with CCD while working in the United Kingdom.

So it’s a good thing our scientists, and their colleagues in Tassie and Brazil, are on the case.

Australian’s museums, galleries and other cultural institutions must adopt more of a digital strategy with their collections if they are to remain relevant with audiences.

Only about a quarter of the collections held by the sector have been digitised so far and a study out today says more needs to be done to protect and preserve the material, and make it available to people online.

Challenges and Opportunities for Australia’s Galleries, Libraries, Archives and Museums is a joint study by CSIRO and the Smart Services CRC.

It notes that Australia’s galleries, libraries, archives and museums (the GLAM sector) represent our accumulated achievements and experiences, inspire creativity and provide a place for us to connect with our heritage.

They are also crucial to our economy with the GLAM sector estimated to have a revenue of about A$2.5 billion each year. That’s not only a lot of paintings and artifacts, but a lot of jobs as well.

But despite its size and scope, we found that digital innovation in the sector has been inconsistent and isolated. If these cultural institutions don’t increase their use of digital technologies and services, they risk losing their relevance.

So what changes do they need to make in order to thrive in the digital economy?

Opening doors and minds

With Australia’s rapid uptake of online and mobile platforms, people are now choosing to access and share information in very different ways.

It’s safe to say that the only constant in this space is change. Research suggests that expectations for more personalised, better and faster services and more well-designed experiences will continue to increase.

Virtual tours are now possible at the National Museum of Australia.

Virtual tours are now possible at the National Museum of Australia.

This is why our cultural institutions need to review the kind of visitor experience they are providing. We found only a few organisations had made fundamental changes to their operations that would allow them to place digital services at their core, rather than as an add-on activity.

This is in contrast to the dramatic changes we’ve seen when it comes to adopting digital technologies in our daily lives.

In order to be successful, digital experiences need to be an integrated and cohesive part of an institution’s offering.

Take what is happening at the National Museum of Australia. It’s now possible to take a tour of the museum via a telepresence-enabled robot.

This means school students – particularly those in rural and regional Australia – can explore exhibits virtually, without even leaving the classroom. Interestingly, we hear that this actually increases their desire to visit the museum in person.

Digital-savvy innovations such as this need to be at the fore of our institutions’ thinking if they want to engage with the community and break down barriers to participation.

Engaging with the public

To be successful in this new era, institutions need to meet people on their own (digital) terms. We can no longer expect visitors to queue at the turnstiles waiting for opening time. Organisations need to bring experiences to the user so that they can access them wherever and however they prefer.

Some of Australia’s cultural institutions are starting to get this.

The NSW State Library has appointed a Wikipedian-In-Residence to contribute expertise and train the public in publishing information online.

The National Library of Australia has attracted a large online user base with its online Trove service attracting almost 70,000 unique users each day.

The Powerhouse Museum has made parts of their photographic collections available on Flickr via Creative Commons licensing. This has caused a surge in the level of use and allowed the public to contribute information, adding value to the collection.

While these examples provide a lot of hope for the sector, the unfortunate reality is that they are few and far between. Most of Australia’s cultural institutions have not kept pace with this change and are missing the opportunity to better connect and actually increase their revenue.

Digitise this!

Australia’s eight national, state and territory art organisations hold archives that, if laid out flat end-to-end, would span 629km. This is on top of a staggering 100,000 million artworks, books and audio-visual items in Australia.

But only a quarter of these items are digitised, with some of Australia’s collections still being managed through “old school” mechanisms such as log books and card indices.

Imagine if there was a fire at one of our great institutions? We would risk losing cultural and heritage material of significance. Parts of our history could be completely lost. Even without such a devastating event, if we don’t make our collections more accessible, in a sense they’ll be lost to many of us anyway.

As a country, not only do we need to get moving when it comes to digitising our collections, we also need to explore new and innovative ways to do this. Traditionally, digitisation has meant scanning flat documents, photographing objects or creating electronic versions of catalogue data.

But what if we could do so much more? Researchers are now focused on the next challenge: digitising objects and spaces in three dimensions.

Researchers from the University of Wollongong with support from the Smart Services CRC are focusing on capturing 3D models and the textures of surfaces using low-cost equipment such as a Kinect camera from an Xbox.

At CSIRO, we’ve even used our own handheld scanner Zebedee to map culturally and environmentally significant sites suchb as the Jenolan Caves, Melbourne’s Shrine of Remembrance and even a semi-submerged wreckage of the HMQS Gayundah.

We’re also creating high-quality 2D and 3D image libraries based on the National Biological Collections, letting us document biodiversity in the digital era.

Embracing the digital economy

While our study reveals that Australia’s cultural institutions are certainly at risk of becoming “digital dinosaurs”, it also demonstrated how those organisations that are embracing digital are reaping the benefits.

It provides recommendations for the GLAM industry in order for it to maximise its digital potential, including:

  • shifting to open access models and greater collaboration with the public
  • exploring new approaches to copyright management that stimulate creativity and support creators
  • building on aggregation initiatives such as the Atlas of Living Australia
  • standardising preservation of “born digital” material to avoid losing access to digital heritage
  • exploiting the potential of Australia’s Academic and Research Network (AARNet) and the National Broadband Network (NBN) for collection and collaboration.

By adopting these recommendations and building on some innovative examples in the sector, Australia’s GLAM industry will be well placed to embrace digital, rather than be engulfed by it.

Our 3D thermal scanner is so hot right now

By Emily Lehmann

If you’re feeling a bit under the weather, you might bring your hand to your forehead and take note of your temperature. Just like your mama used to do.

Running a high temperature is an age-old giveaway that you’re sick with a fever and that you better check in with your doc or stay at home in your PJs.

Like your body heat is a sign of a fever, deep down at a cellular level, it can also be an indicator of other serious illnesses and diseases. Cancer is one example because cancer cells are typically higher in temperature than healthy cells.

We’ve come up with a hot new thermal mapping and 3D imaging technology called HeatWave that could one day be used by health professionals to detect and monitor certain cancers.

HeatWave could be usef for early detection and monitoring of injury and disease.

HeatWave could be used for early detection and monitoring of injury and disease.

A key advantage of thermal scanning is that it’s radiation-free, reducing risks to patients imposed by other forms of tomography and repeat scans can be undertaken after shorter periods of time.

While there are other thermal scanning technologies out there being used by health professionals, unlike HeatWave, they are only capable of producing 2D images.

This means that repeat images need to be taken at exactly the same angle to achieve an accurate picture of changes to the area of the body. They are also difficult and require years of practice and expertise – something which HeatWave overcomes.

The HeatWave device

The HeatWave device

Early cancer detection is just one of the many great applications envisaged for the technology and we’ve just won an award for it.

HeatWave took home the national research and development award at the iAwards on Friday night, recognised as a cutting edge innovation.

The handheld mobile technology can generate precise 3D models of objects or scenes, overlaid with accurate temperature information in real time.

Consisting of a 3D camera and thermal sensors, HeatWave can be literally waved around objects and spaces to collect data. This data is then turned into high-resolution 3D images.

Thermal imaging is growing rapidly and HeatWave is expected to have a range of applications in industries including energy, construction, manufacturing, agriculture and emergency services.

Will robots ResQu our rainforests from weeds?

By Carrie Bengston

Want to go for a walk in a rainforest? Join us!

We push our way past vines tangled around tree limbs in the dark, multilayered forest.  As we walk, we’re aware that we’re the only people in this tranquil environment. But it’s a place that’s home to rare and unique birds like the cassowary, a fantastic collection of fungi, and unusual mammals like the tree kangaroo. We step across clear, freshwater creeks (plus or minus leeches) and we listen to leaves rustle in the canopy as a thunderstorm approaches, rumbling in the distance.

Our rainforests are precious and incredibly biodiverse. For example, the rainforests of Far North Queensland, which include the iconic Daintree, occupy less than 0.2 per cent of Australia’s land mass. Yet they support more than ten percent of its flora, 36 per cent of its mammals and 48 per cent of its birds. Rainforests are confined to small patches clustered mostly in inaccessible, mountainous regions along the tropical coast. It’s important we look after these amazing habitats. Unfortunately, a purple-leafed weed, Miconia calvescens, has escaped from its natural habitat overseas via introduction into Aussie gardens and nurseries (which has since been banned) and has made its way into our World Heritage rainforests.

Purple is a great colour. Don’t get us wrong. But these purple weeds have no place in our rainforests as they compete viciously for space, and squeeze out our native plants. The Miconia menace is taking over the rainforests of Tahiti and other countries. We don’t want that happening here. So we’ve called on an unlikely ally to stop Miconia getting a roothold – robotic technology.

We’ve been participating in a research project, Project ResQu, to trial robot helicopters that could do some of the weed spotting people currently do. Weed spotters work on the ground pushing through dense forest or flying above in manned helicopters, but robots can do the job better and safer. We recently put that to the test.

The robots did well. The robot helicopters, fitted with radar and special cameras and given quirky names like ‘Hotel Golf’, found several Miconia infestations missed by other methods of surveillance. Here’s how we did it.

Will robots save the rainforest? They just might.

About Project ResQu:

Project ResQu is a two-year, $7M project led by the Australian Research Centre for Aerospace Automation (ARCAA) in a collaborative project between the Queensland University of Technology (QUT), CSIRO, Boeing and Insitu Pacific with the support of the Queensland State Government Department of Science, Information Technology, Innovation and the Arts.

Bungees get wet – for science

Bungee jumper

Not this kind of bungy. Image: Flickr/fauzay

When you hear the word ‘bungee’ you don’t immediately think of ocean research. But the daredevil’s rubbery, stretchy friend is now doing its bit to assist in ocean and coastal science.

In order to hold monitoring equipment in place, marine and aquaculture researchers currently use chain to attach their equipment to moorings anchored to the ocean floor.

This is effective, but it can have some undesirable side effects. Marine chain is heavy. It has to be to withstand the power of the ocean. Unfortunately, this means that the weight of the chain moorings can damage the delicate sea floor, gouging bits out as it drags along.

Chain also takes up a lot of space. Because there needs to be some give (to prevent it from snapping), the chain needs to be much longer than the depth of the water. This is also a factor for aquaculture – the more ocean floor real estate occupied by chain, the less room they have for their production.

So what if there were a mooring that dispensed with the need for all that chain? A little lateral thinking, and … meet our home-grown bungee mooring, developed in partnership with Hobart-based company Specialised Industrial Products.

Just the same way as a standard bungee cord stretches and stretches and S-T-R-E-T-C-H-E-S, so does the rubber cord attached to the mooring hardware – up to five times its length at rest. This allows it to move with the dynamics of the water, instead of resisting it. As a result, the mooring can be smaller, lighter and take up less space on the ocean floor.

A bungee that goes UP.

A bungee that goes UP.

Not only that – the slimline design means it’s less vulnerable to fouling, which is the encrusting of small marine animals, plants and algae on the surface. That reduces the drag and load even further. Stretching instead of straining also lessens the stress on the coupling points, saving investment costs, maintenance cost and downtime. Our new bungee cords are estimated to have twice the working life of a traditional chain mooring, at about the same initial cost – around $1000 each.

This is just one of a, er, raft (see what we did there?) of marine innovations we have made in collaboration with industry. For more information contact Tim Lynch on tim.lynch@csiro.au or (03) 6232 5239.


3D printed bling!

Here at our titanium 3D printing facility Lab 22, we print all sorts of things. From biomedical devices like this sleep apnoea mouth guard, to titanium lugs for this bicycle manufacturer.

We do this because 3D printing has a bucket load of advantages over traditional manufacturing methods. It reduces wasted material, brings down costs, speeds up development and allows for product customisation. It’s a technology that is already opening up doors in the automotive, aerospace and health industries.

Now, Australia’s local design community is jumping on 3D printing. With rapid prototyping, the technology is allowing designers to bridge the gap between the conceptual and tangible with a press of a button.

As part of the Sydney Design Festival, underway this week, the Third Dimension Pop Up exhibition is showcasing what Australian designers are achieving with this innovative technology. Here’s one of the titanium pieces we printed at Lab22 for local designer Caitlin Dubler. We think it’s pretty cool.
