Sustainable Manufacturing Research
We conduct research and innovation into sustainable products, processes, materials and supply chains, supporting manufacturing industry as it evolves towards a circular economy. For global long term prosperity, health and resilience manufacturing needs to evolve from a model of high resource consumption and waste production towards one that is resource neutral/ zero waste. Making the circular economy a reality is a major challenge for researchers and industry but working together we can develop sustainable products, processes, materials and supply chains. We provide bespoke manufacturing solutions to improve sustainability of products and processes, reduce waste and energy usage, increase resilience of supply chains and develop new environmentally-friendly materials.

Micro and Nano Manufacturing Research
The Micro and Nano Manufacturing (MNM) laboratory has been conducting research in this field since 2002. The MNM Lab carries out research in processes and process chains complementary to semiconductor-based fabrication techniques. The main driver is to advance manufacturing knowledge and applications for producing components and devices with micro and nano-scale functionalities in a wide range of materials. The MNM Lab has been involved in national and international collaborative research initiatives, which include leading organisations in Europe (KIT, DTU, IK4-TEKNIKER) and further afield (HIT China) as well as a number of key industrial partners (Zimmer-Biomet, Renishaw). Our facilities enable the direct machining or the replication of features ranging from a few tens of nanometres to a few hundred micrometres. These include short and ultra-short pulsed laser systems, a micro EDM machine and a micro injection moulding machine. These are completed by advanced micro- and sub-micrometre characterisation equipment for dimensional inspection (optical microscopes, white light interferometer, SEM), and for material characterisation and/or for nano-manufacturing operations (atomic force microscope, focussed ion beam). The MNM lab conducts research across a range of application areas including:
- Nanomachining for future magnetic-based data storage devices - Nanoscale machining realised with the tip of an AFM probe is used to create nanostructures for controlling magnetic domain walls along NiFe nanowires.
- Laser surface texturing of orthopaedic implants - Pulsed ns laser irradiation of biomedical material is conducted for investigating the effect of different surface textures on the wear resistance of implants.
- Micro mechanical machining of aerospace materials - Expertise in numerical simulation enables the modelling of the cutting process of advanced composite materials.
- Computer-aided micro manufacturing - AI tools are developed for the virtual design and automated control of MNM process chains.
- Post processing of 3D printed metallic components - Micro features are integrated on metallic components produced by ALM to improve surface finish and functionalization.
Robotics and Autonomous Systems Research
One of our major research interests is in Robotics and Autonomous Systems, in particular to endow a higher level of autonomy to unmanned systems, providing capabilities of advanced situation awareness, localisation and mapping, path planning, and multiple robot collaboration. We aim, as part of this research, to enable direct and safe collaboration between humans and robots to accomplish difficult tasks together that are beyond individual human capabilities, such as assembly, lifting heavy objects and logistics.
One of our long-term research aims is to enhance the robot cognitive capability by deploying advanced perceptual capabilities, such as vision, RGB-D, Lidar, and other sensors, in order to interpret human gestures, understand environments, and eventually become natural companions of humans. Currently we are working in three main research areas related to robotics.
We have invested in a Robotics and Autonomous Systems Laboratory with a range of cutting-edge equipment which supports our research.
Mobile Robotics and Autonomous Vehicles
We aim to investigate safe and reliable navigation solutions for autonomous vehicles and mobile robots to operate in real-world environments that are safety-critical, dynamic, and unstructured.
The research is focused on developing intelligent algorithms processing and interpreting large amount of sensing data from Lidar and computer cameras for environmental mapping and robot localisation in GPS denied environments. Our Robotics Laboratory currently has several mobile robots, including three Kuka Youbots, a number of Turtlebots and also some Drones.
We have also developed an unmanned surface vehicle (USV) that can autonomously navigate and avoid collisions by using Lidar and vision for obstacle detection. The project is now being undertaken by a group of students working on a landing system for the drone to track and land on the USV autonomously.
Robots in Unstructured Domestic Environments
We are also working on the development and prototyping of autonomous robotic solutions in domestic environments to support elderly people to live independently. Our research focus is on domestic service robots designed to enable:
- Intent-based remote control for robust tele-operation over a real-world communication network.
- Adaptive autonomy to enable a highly efficient task execution for remotely controlled service robots.
- Robotic self-learning mechanisms to enable robots to learn from their experience.
- A safety-oriented framework derived through extensive usability and user acceptance studies that enable service robots to be effectively deployed into home care applications.
Another focus for us is the use of multimodal human computer interfaces allowing natural human robot interactions through gaze tracking, brain-computer interfaces (BCI), and human gesture understanding.
We are also working on multi robot systems that accommodate heterogeneous agents, including human operators. This is especially challenging, particularly for large applications. Introducing humans into the loop presents even more technical challenges including:
- environmental understanding through visual object recognition and pose identification for grasping and manipulations in unstructured workspace
- human behaviour monitoring and understanding
- shared task planning for robots and humans or multiple robots
- robot programming by demonstration, where robots learn new skills by observing demonstration by human operators.
