Mind-controlled robots based on graphene: an Australian research story

Leave a reply

As they keep saying these days, ‘it’s not science fiction anymore’.

It’s so fascinating I almost forgot what it’s like to make a video where it can take hours to get a few minutes (the video is a little over 3 mins.) and all the failures are edited out. Plus, I haven’t found any information about training both the human users and the robotic dogs/quadrupeds. Does it take minutes? hours? days? more? Can you work with any old robotic dog /quadruped or does it have to be the one you’ve ‘gotten to know’? Etc. Bottom line: I don’t know if I can take what I see in the video at face value.

A March 20, 2023 news item on Nanowerk announces the work from Australia,

The advanced brain-computer interface [BCI] was developed by Distinguished Professor Chin-Teng Lin and Professor Francesca Iacopi, from the UTS [University of Technology Sydney; Australia] Faculty of Engineering and IT, in collaboration with the Australian Army and Defence Innovation Hub.

As well as defence applications, the technology has significant potential in fields such as advanced manufacturing, aerospace and healthcare – for example allowing people with a disability to control a wheelchair or operate prosthetics.

“The hands-free, voice-free technology works outside laboratory settings, anytime, anywhere. It makes interfaces such as consoles, keyboards, touchscreens and hand-gesture recognition redundant,” said Professor Iacopi.

…

A March 20, 2023 University of Technology Sydney (UTS) press release, also on EurekAlert but published March 19, 2023, which originated the news item, describes the interface in more detail,

“By using cutting edge graphene material, combined with silicon, we were able to overcome issues of corrosion, durability and skin contact resistance, to develop the wearable dry sensors,” she said.

A new study outlining the technology has just been published in the peer-reviewed journal ACS Applied Nano Materials. It shows that the graphene sensors developed at UTS are very conductive, easy to use and robust.

The hexagon patterned sensors are positioned over the back of the scalp, to detect brainwaves from the visual cortex. The sensors are resilient to harsh conditions so they can be used in extreme operating environments.

The user wears a head-mounted augmented reality lens which displays white flickering squares. By concentrating on a particular square, the brainwaves of the operator are picked up by the biosensor, and a decoder translates the signal into commands.

The technology was recently demonstrated by the Australian Army, where soldiers operated a Ghost Robotics quadruped robot using the brain-machine interface [BMI]. The device allowed hands-free command of the robotic dog with up to 94% accuracy.

“Our technology can issue at least nine commands in two seconds. This means we have nine different kinds of commands and the operator can select one from those nine within that time period,” Professor Lin said.

“We have also explored how to minimise noise from the body and environment to get a clearer signal from an operator’s brain,” he said.

The researchers believe the technology will be of interest to the scientific community, industry and government, and hope to continue making advances in brain-computer interface systems.

For anyone who’s bothered by this, the terminology is fluid. Sometimes you’ll see brain-computer interface (BCI), sometimes you’ll see human-computer interface, or brain-machine interface (BMI) and, as I’ve now found in the video although I notice the Australians are not hyphenating it, brain-robotic interface (BRI).

You can find Ghost Robotics here, the makers of the robotic ‘dog’.

There seems to be a movement to replace the word ‘soldiers’ with warfighters and, according to this video, military practitioners. I wonder how medical doctors and other practitioners feel about the use of ‘practitioners’ in a military context.

British soldiers conduct field trials of uniforms made from e-textiles

I gather that today’s soldier (aka, warfighter)  is carrying as many batteries as weapons. Apparently, the average soldier carries a couple of kilos worth of batteries and cables to keep their various pieces of equipment operational. The UK’s Centre for Defence Enterprise (part of the Ministry of Defence) has announced that this situation is about to change as a consequence of a recently funded research project with a company called Intelligent Textiles. From Bob Yirka’s April 3, 2012 news item for physorg.com,

To get rid of the cables, a company called Intelligent Textiles has come up with a type of yarn that can conduct electricity, which can be woven directly into the fabric of the uniform. And because they allow the uniform itself to become one large conductive unit, the need for multiple batteries can be eliminated as well.

…

The company says it has found a way to weave the conductive yarn into virtually all parts of the uniform: vest, shirt, backpack, helmet, even gloves or the interactive parts of weapons. Different pieces of the uniform can then be connected via plug-and-play connections when the soldier dresses for battle, … They say they are currently also working on a keyboard that can also be integrated into a uniform to allow for interaction with a small computer that will also be carried as part of the uniform.

Field trials are scheduled for next month and uniforms made with e-textiles are expected to begin being worn by actual soldiers over the next two years.

You can find the Centre for Defence Enterprise (CDE) here, from the CDE’s home page,

The Centre for Defence Enterprise (CDE) is the first point of contact for anyone with a disruptive technology, new process or innovation that has a potential defence application. CDE funds research into novel high-risk, high-potential-benefit innovations sourced from the broadest possible range of science and technology providers, including academia and small companies, to enable development of cost-effective capability advantage for UK Armed Forces.

CDE is the entry point for new science and technology providers to defence, bringing together innovation and investment for the defence and security markets.

Here’s a link to a video featuring an employee from Intelligent Textiles discussing their new product and the joys of applying for funds from the CDE.

I did try to find out more about Intelligent Textiles. While they do have a website, it is currently under construction, here’s an excerpt from their home and only page,

Welcome to this very special first glimpse of a new 21st century world. A wonderful world of soft, safe, stylish, comfortable, colourful fabrics which not only do all the traditional fabric things but which discreetly and unobtrusively include a host of additional attributes.

The new world of Intelligent Textiles is limited only by your vision and needs, and the enthusiasm by innovative manufacturers to embrace a new world.

Building on the best of the past, see an amazing high tech future using traditional techniques and materials with the addition of the Intelligent Textiles globally patented technology.

Even after reading the news item, watching the video clip, and reading the information on Intelligent Textile’s home page, I don’t really understand the benefit of  the technology. It’s nice that cables are being eliminated but it sounds as if at least one battery is still needed (and probably one backup just in case something goes wrong) and they have plans to include a computer in the future. Are they eliminating five pounds of equipment and replacing it with one pound’s worth? If they include a computer in the future, how much weight will that add?
