A UTS project was showcased at the Army Robotics Expo in Brisbane, showing how users can remotely control a robotic vehicle using brainwaves, or electrical signals generated by coordinated neuronic activity in the brain.
At the Army Robotics Expo in Brisbane, Defence staff and industry participants demonstrated how users can remotely control a robotic vehicle using “brainwaves” – electrical signals generated by coordinated activity of neurones in the brain.
The project, led by Distinguished Professor CT Lin and Professor Francesca Iacopi was funded by the Department of Defence through the Defence Innovation Hub open submission process, valued at $1.2m AUD.
The UTS team showed robotic devices moving in the event space without the users using their hands. The intended robot movement was communicated through physiological sensors, which detected and decoded electrical brain signals – or brainwaves – and sent them to the device.
Professor Iacopi is developing innovative sensors for this project using graphene – a single, thin layer of graphite, which is the same material found in lead pencils. The graphene is embedded in silicon wafers to create a material that is highly resilient, biocompatible and conductive for a better prolonged contact with the human skin. The project team has been delving into the factors that make graphene ideal for technologies that will be worn on the skin in the wide range of climates and environments that are experienced in the Army.
Professor Iacopi is an internationally-recognised expert in nanotechnology and electronic materials and a Chief Investigator in the Australian Research Council Centre of Excellence in Transformative Meta-Optical Systems.
Professor Lin is developing the wearable electronics and artificial intelligence algorithms for decoding the brain signals and controlling a robotic device. He is an international expert on brain computer interface and computational intelligence and Co-Director of the Australian Artificial Intelligence Institute at UTS.
Currently people use touch to control phones and tablets. In the future you will have sensors embedded in gear that can detect brain signals and communicate with computers and smart appliances using thought. Distinguished Professor Lin.
As well as defence applications, this wearable technology being developed at UTS has significant potential for people with disability. It could facilitate many aspects of daily living, including controlling a wheelchair or operating prosthetics.
The project aims to build the capability of our defence forces and our high-tech industries and jobs, with the innovative technology having potential commercial applications across multiple sectors. Professor Iacopi.
This UTS project began in 2020 and is due for completion in 2022. It builds on UTS’ research in AI, robotics and innovative materials.
