Robotic Triage For Value Retention In Circular Economy (RoboTriage)

Yongjing Wang (Principal Investigator)
Value: £1.8M (FEC) including £1.5M from the EPSRC
Duration: 2024-2027
 
Abstract: 

Current Circular Economy practices often underutilise the potential of end-of-life products, with many being inefficiently recycled. This research addresses the critical need for scalable methods to separate heterogeneous used products for optimal valorisation (reuse, repair, remanufacturing, repurposing). Existing evaluation relies on subjective human judgment, leading to inefficiencies.

This research introduces “circularity triage,” a concept inspired by healthcare triage, involving the rapid, systematic assessment of products to determine their highest-value CE pathway. We aim to develop robotic systems capable of performing this triage by capturing product health data, enabling swift condition evaluation, segregation of similar items, and recommendations for optimal CE options.

The project’s objectives include creating robotic triage systems, developing intelligent planning for these systems, identifying correlations between product history and condition via large-scale robotic analysis, exploring value opportunities and circular business models based on these insights, and demonstrating industrial uptake through case studies.

This research promises significant academic impact across ICT, AI, and data science, with broader economic, societal, and environmental benefits. RoboTriage technologies offer the potential to scale CE practices, enhance productivity, and drastically reduce primary material use and energy consumption, exemplified by our industrial partnerships and international collaborations with the UN.

Robotic skill transfer and augmentation for contact-rich tasks in manufacturing (STAMAN)

Yongjing Wang (Principal Investigator)
Value: £1.3M (FEC) including £1M from the EPSRC
Duration: 2024-2027
 
Abstract: 

STAMAN’s vision is to create AI-based mechanisms to allow robots to share and recreate obtained digital skills (e.g. motion and force/torque control strategies) to allow easy automation scale-up for contact-rich tasks. This includes considering two research questions:

1) For skill transfer – how can a contact-rich skill be quickly transferred to a different robot (e.g. transferring a bolt-nut separation skill from a high-precision robot to a low-precision robot)?

2) For skill augmentation – how can existing contact-rich skills be used to create new contact-rich skills (e.g. augmentation of rigid-material skills to deal with soft materials)?

The project will develop a portfolio of research into the science of digital skills for contact-rich tasks, focusing on common manufacturing tasks such as bolt-nut assembly/disassembly, peg-hole insertion/separation, and shaft-ring assembly/disassembly. The ability to transfer and augment digital skills for contact-rich tasks will allow automation systems to be implemented on a larger scale, with minimal manual setting and fine-tuning required. STAMAN aims to create transferrable and augmentable digital skills that will underpin the development of mass machine skills for future manufacturing, similar to how industrial robots have contributed to modern mass production.

The proposed research encourages more use of robots in assembly (e.g. automotive, aerospace, electronics, etc.) and disassembly (e.g. repairs, remanufacturing and recycling), and thus directly contributes to the UK’s Made Smarter initiative and the circular economy goals.

EPSRC Manufacturing Research Hub in Robotics, Automation & Smart Machine Enabled Sustainable Circular Manufacturing & Materials (RESCu-M)

Yongjing Wang (Co-Investigator and Theme 2 Co-lead)
Value: £15M (FEC)
Duration: 2024-2031
 
Abstract: 

The UK government and UN are pushing for a Circular Economy to tackle climate change and maintain living standards, as global material consumption and waste are set to skyrocket. Traditional manufacturing’s linear “make-use-dispose” model is unsustainable, especially for critical materials vital for technologies like batteries and medical devices. Extending the lifespan of these materials through reuse, repair, remanufacturing, and recycling (Re-X) is crucial but currently inefficient and labour-intensive, hindering widespread adoption.

This hub aims to revolutionise circular manufacturing by integrating AI and intelligent automation to create a new ecosystem for high-value product resource use, positioning the UK as a global leader. Its grand challenges are to radically improve critical material sustainability (>75% component reuse, >20% material use decrease, >50% component reclaim increase) and to make Re-X manufacturing productivity equal to or better than traditional methods (>10 times improvement).

The hub will foster interdisciplinary research in smart Re-X processes, material state tracking, circular design, life validation, and new business models. Focusing on energy, medical devices, electric drives, and large structures, the hub’s Robotics and AI solutions will significantly reduce environmental impact, targeting 80% of high-value product impact and aiming to save over 8 million tonnes of CO2 annually.

Affordable and modular robotic disassembly systems (EPSRC IAA )

Yongjing Wang (Principal Investigator)
Value: EPSRC IAA Follow on rate
Duration: 4/2023-11/2023
 
Abstract: 
Disassembly is a key step in remanufacturing and recycling. The status quo of disassembly for many consumer products is economically unjustifiable, mainly because of a lack of enabling technologies for the automation of disassembly. Also, some products, such as lithium-ion batteries from electric vehicles
and medical equipment, involve significant health and safety risks in disassembly (e.g. leakage and explosion), making disassembly expensive and difficult to scale up. 
In this project, we aim to significantly reduce the cost of robotic technologies by improving the design of the disassembly robot system to create a general-use low-cost robotic disassembly robot station (e.g. a single robot cell) that can be used for *** and *** – the two major disassembly operations to disassemble common consumer products. 
AMRD aims to develop a STANDARDISED robotic disassembly work cell that can be adopted in a variety of disassembly tasks with easy programming. It offers significantly more functionalities and a higher level of automation than the basic disassembly equipment, and significantly lower costs than the customised
solutions. Being standardised means the proposed robotic disassembly product can be mass-duplicated and mass-produced which will pave the way for scale-up.

Automatic disassembly replanning for autonomous remanufacturing

Yongjing Wang (UK Principal Investigator)
Value: £12k from the Royal Society and £12k from NSFC
Duration: 03/2019-03/2022
 
Abstract: 
A key step in remanufacturing is disassembly of the returned product to be remanufactured. Disassembly sequence planning is challenging due to uncertainties in the conditions of the returned products and complex recovery procedures involving human operators and machines. Rust, corrosion, deformation and parts missing may require disassembly plans to change
and adapt frequently. Current industrial robotic techniques, most of which designed for repetitive and structured motions in assembly, do not have the required flexibility for disassembly. The project will facilitate autonomous multi-agent model and optimal replanning to deal with unforeseen changes in
robotic disassembly processes. We expect to produce scientific results relevant to researchers in robotics, modelling & simulation, remanufacturing and recycling. The resultant techniques will promote the flexibility and robustness of robotic disassembly systems, and thus encourage a wider adoption of remanufacturing.
