Podium Institute’s Postdoctoral researcher Chenying Liu’s project ‘Origami-Informed Robots’ was showcased in Dubai as part of the emirate’s annual programme which celebrates researchers working on social and environmental challenges.
Established by the UAE’s Dubai Future Foundation, the Prototypes for Humanity programme celebrates and supports academics and research students from across the globe whose work seeks to address some of the most urgent social and environmental challenges facing our species. The programme sees government, investors and industry come together to ‘advance academic research into viable entities’.
One way in which this is done is through annual Prototypes for Humanity Awards, where prizes are awarded to the students and lead academic behind each of the best solutions across five categories – energy, civil society, nature, AI and data science, and health – with the 2024 prize pot totalling $100,000. More than 2,700 submissions were made to Prototypes for Humanity by researchers and students from over 800 universities in over 100 countries. As well as selecting the five winning projects, which included Oxford Engineering DPhil student Xinpeng Hong, the 2024 jury chose just 100 projects to appear in a Dubai showcase last November.
Dr Chenying Liu is a Postdoctoral Researcher at the Podium Institute for Sports Medicine and Technology, and Stipendiary Lecturer in Engineering at Christ Church college, prior to which she completed her DPhil in Engineering Science under the supervision of Professors Zhong You (Special Structures Group) and Perla Maiolino (Soft Robotics Lab). In her research, Dr Liu explores how origami (i.e. paper folding) gives rise to remarkable mechanical properties and how insights drawn from this investigation leads to new applications in the fields of healthcare and sustainability technology.
In her latest project, Dr Liu sets out to address limitations of ‘soft robots’. Unlike traditional robots with rigid metal arms, soft robots are an emerging type of robot made from soft materials, similar to those found in natural organisms. Materials like silicone rubber can mimic the behaviour of muscles and skin, making soft robots more adaptable to their environment and safer for human interaction. However, their softness poses challenges, such as difficulty in maintaining their shape and controlling their movements. This is the problem that Dr Liu’s showcased project, entitled ‘Origami-Informed Robots’, endeavours to solve.
Origami, with its combination of rigid facets and flexible joints, offers a balance of rigidity and flexibility. The advance that Dr Liu’s research makes is in the application of origami techniques to more robust engineering materials: “Despite its potential, traditional origami faces limitations due to its reliance on paper. My project addresses this by not only applying origami principles to replace soft materials in robots but also investigating fundamental folding techniques to incorporate durable engineering materials like plastics, wood, and even metal.”
This marrying of the benefits of rigidity and flexibility leads to a host of real-world applications in sectors as diverse as agriculture and waste management. Dr Liu has been able to develop adaptable grippers capable of handling delicate objects, such as eggs or soft-skinned fruits (e.g. strawberries and blueberries) – a cost-effective and practical solution for agricultural harvesting. She has also applied her research to the design of dexterous manipulators for handling hazardous materials in nuclear plants, which reduce human exposure to dangerous and tedious tasks. A third, perhaps unexpected application of the technology is in millipede-like robots that can transform into circular, wave-like, or triangular shapes to navigate confined spaces, offering great potential in disaster rescue operations.
“I am delighted to have had the opportunity to present how small folding structures can have a big impact on society”
Dr Liu was delighted to have her project selected for the Prototypes for Humanity exhibition: ‘It was a great honour to showcase my work as part of the Prototype for Humanity exhibition in Dubai. I am delighted to have had the opportunity to present how small folding structures can have a big impact on society. This project builds on my doctoral research in the Department of Engineering Science at the University of Oxford, supervised by Professors Zhong You and Perla Maiolino, who bring complementary expertise in origami structures and soft robotics. I have also worked closely with Professor Liang He, whose insights have been invaluable throughout the project.
Working with Professor Liang He at the Podium Institute, Chenying seeks to expedite her origami expertise to healthcare applications. Currently, she is developing origami-inspired personal protective equipment (e.g., helmets and exoskeletons) with improved protection and personalised design.
