A Sheffield robotics firm is revolutionising the way defence manufacturers automate component finishing, a critical yet often overlooked stage in production. Rivelin Robotics' 'microfactory' uses artificial intelligence (AI) to achieve human-like precision and dexterity in cleaning and refining manufactured parts, eliminating slow, costly, and hazardous manual processes.
The innovation tackles a long-standing challenge within defence supply chains: the need for hand-finishing components after they leave production lines. Whether 3D printed, cast or machined, parts often have rough edges, excess material and surface imperfections requiring meticulous clean-up before use. This manual work is time-consuming, inconsistent and poses occupational risks to workers.
Rivelin Robotics received crucial support from UK Defence Innovation (UKDI), previously known as the Defence and Security Accelerator. Funding and technical assistance from the Defence Science and Technology Laboratory (Dstl) enabled the startup to evolve its concept into a deployable solution. Early access to potential end-users, including the Royal Air Force and British Army, allowed Rivelin to refine its technology based on real-world operational needs.
The backing has been substantial for Rivelin Robotics. The company has expanded from one founder to 21 employees in Sheffield and successfully sold 11 robotic microfactories to customers in Spain, France, Germany and the US. Founder Robert Bush highlighted that UKDI's endorsement provided financial resources, but also a significant boost in credibility – acting as a 'stamp of approval' attracting further interest from potential customers and investors.
This technological advancement offers a solution for scenarios such as a naval vessel far from home requiring a replacement part. Instead of waiting weeks or paying high prices for local fabrication, an automated finishing system could facilitate quicker, more cost-effective on-demand production – building resilience into defence supply chains and reducing taxpayer costs for the UK armed forces and its allies.
