A pioneering challenge to develop superior sensors to be used in robotic techniques, may remodel prosthetics and robotic limbs.

The analysis challenge—led by University of the West of Scotland (UWS), Built-in Graphene Ltd, and supported by the Scottish Research Partnership in Engineering (SRPe) and the Nationwide Manufacturing Institute for Scotland (NMIS) Trade Doctorate Program in Superior Manufacturing—goals to develop sensors which give enhanced capabilities to robots, serving to enhance their dexterity and motor skills, via using correct stress sensors which give haptic feedback and distributed contact.

Professor Des Gibson, Director of the Institute of Skinny Movies, Sensors and Imaging at UWS and challenge principal investigator, stated: “Over current years the developments within the robotics trade have been outstanding, nevertheless, resulting from an absence of sensory capabilities, robotic techniques usually fail to execute sure duties simply. For robots to achieve their full potential, correct stress sensors, able to offering larger tactile means, are required.

“Our collaboration with Integrated Graphene Ltd, has led to the development of advanced pressure sensor technology, which could help transform robotic systems.”

Constituted of 3D graphene foam, which provides distinctive capabilities when put underneath mechanical stress, the sensors use a piezoresistive strategy, which means when the fabric is put underneath stress it dynamically adjustments its electrical resistance, simply detecting and adapting to the vary of stress required, from mild to heavy.

Marco Caffio, co-founder and Chief Scientific Officer at Built-in Graphene stated: “Gii, our novel 3D graphene foam, has the aptitude to imitate the sensitivity and suggestions of human contact, which may have a transformative influence on how robotics can be utilized for an entire vary of real-world purposes from surgical procedure to precision manufacturing.

“We know the unique property of Gii makes it suitable for use in other applications like disease diagnostics and energy storage, so we’re always very excited to be able to demonstrate its flexibility in projects like this one.”

Dr. Carlos Garcia Nunez, Faculty of Computing Engineering and Bodily Sciences at UWS added: “Within robotics and wearable electronics the use of pressure sensors is a vital element, to provide either an information input system, or to give robotic systems human-like motor skills. An advanced material like 3D graphene foam offers excellent potential for use in such applications, due to its outstanding electrical, mechanical and chemical properties.

“Our work shines a light on the significant potential for this technology to revolutionize the robotics industry with dynamic pressure sensors.”

Claire Ordoyno, Interim Director of SRPe, added: “The SRPe—NMIS Industrial Doctorate Program brings together ground breaking academic research with industry partners to drive forward innovation in engineering. These collaborative Ph.D. projects not only enhance the Scottish engineering research landscape, but produce innovation focussed, industry ready Ph.D. graduates to feed the talent pipeline.”

The following stage of the challenge—funded by UWS, Built-in Graphene Ltd, SRPe and NMIS—will look to additional improve sensitivity of the sensors, earlier than creating for wider use in robotic systems.

Automation and advanced materials are the ‘dream team’
