Professor Robert Buckingham Celebrated on New Year’s Honour List

RAIN’s Professor Rob Buckingham has been awarded an Officer of the Order of the British Empire (OBE) for his services to robotic engineering. The UK Atomic Energy Authority’s (UKAEA) Robotics Director was one of those named in the full New Year Honours list for 2021, which recognises the achievements and service of extraordinary people across the United Kingdom. The awards will be presented by Queen Elizabeth II or her vice-regal representative.

Remote Inspection of the Reactor 4 Shelter’s Western Wall

In October 2020, a Bristol University research team with engineers and scientists from the Interface Analysis Centre deployed a semi-autonomous robot for remote radiation inspection inside the Chornobyl Nuclear Power Plant (ChNPP) in Ukraine. The objective of this visit was to create a radiation map of the western wall of the Shelter Object, known as the Sarcophagus, a temporary containment structure hastily erected over the remains of Reactor 4 in the aftermath of the accident on 26 April 1986. The Shelter is facing structural integrity challenges and will need to be dismantled the upcoming years to take the contained reactor remains apart.

By deploying a specialised sensor system called YanDavos on Boston Dynamics’ quadrupedal robotics platform Spot, the researchers were able to acquire an accurate dose rate map of the Shelter’s wall without exposing humans to high radiation levels. Spot moved the sensor system into position in an environment where the dose rate exceeds 100 µSv/h, a hazardous radiation level for humans, and remained there until the scan was completed. YanDavos was designed and developed at Bristol University by RAIN researchers, and combines state-of-the-art gamma spectroscopy, simultaneous single point Lidar ranging and 15 FPS solid state Lidar ranging with 4K cameras to produce detailed radiation maps that can be used to plan decommissioning activities. Spot also completed a radiation mapping test around the outer perimeter of the Shelter as a training exercise for its radiation mapping algorithms.

Dr Cardoso and Dr Ferrando secondment to NIST – US

RAIN researcher’s Dr Rafael C. Cardoso and Dr Angelo Ferrando were not able to go to their secondment at the National Institute of Standards and Technology (NIST) in the US because of the COVID-19 pandemic. Instead, they have been collaborating virtually with NIST in two different projects.

Dr Cardoso is leading the project on agile tasking of robotic systems with explicit verifiable autonomy. Task agility is an increasingly desirable feature for robots in application domains such as manufacturing. The Canonical Robot Command Language (CRCL) is a lightweight information model built for agile tasking of robotic systems by NIST. CRCL replaces the underlying complex proprietary robot programming interface with a standard interface. In this project, we exchange the automated planning component that CRCL used in the past for a rational agent in the Gwendolen agent programming language, thus providing greater possibilities for formal verification and explicit autonomy. We have evaluated our approach by performing agile tasking in a kitting case study.

Dr Ferrando is leading the project on runtime verification of the ARIAC (Agile Robotics for Industrial Automation Competition) competition. ARIAC is a robotic competition which aims to advance robotic agility in industry. Participants in this competition are required to implement a robot control system to overcome agility challenges in a simulated environment. ARIAC comes with a set of score metrics to evaluate the performance of each control system during task execution. In this project, we show how such task-oriented evaluation can be problematic and how the addition of runtime monitors to verify properties given in ISO/TS safety standards can help in reducing the resulting reality gap. In particular, we focused on an initial case study where a safety property given in ISO/TS 15066:2016 is used to synthesise a monitor.

ISCF Robots for a Safer World Cross-Hub Activities

The Use of Digital Twins for Robotic Inspection, Maintenance and Repair 

The use of robots and AI represents the future of critical infrastructure inspection, repair and maintenance.  Through the ISCF’s ‘Robots for a Safer World’ scheme, four world-leading research hubs; FAIRSPACE, NCNR, ORCA and RAIN, have been developing solutions for use in hazardous and challenging environments, such as those found in the nuclear, offshore and space sectors.

Significant research has been undertaken across the Hubs in the use of digital twins as part of robotic inspections.  To maximise the impact of this research, a new cross-hub initiative has been launched on ‘Digital Twins and Digital Tissue for Robotic Inspections, Maintenance and Repair’. 

As well as enabling the sharing of state-of-the-art research between the hubs and fostering a collaborative community, it is also allowing researchers to continue their research during the Covid-19 pandemic lockdown. 

For example, NCNR researchers from the University of Lincoln have been able to control a mobile robot from the RAIN Hub at the University of Oxford.  Teams from the University of Manchester are working to control a mobile robot from the ORCA Hub at Heriot-Watt University as well as robot manipulators from the FAIRSPACE Hub at the University of Edinburgh.

This video showcases some of the cutting-edge research which forms the foundation of the cross-hub initiative.

Robotic inspection of active sites at Dounreay

The RAIN Hub has successfully trialled a robot in an active deployment at the Dounreay Site Restoration Ltd (DSRL) nuclear reactor research facility, now in the process of decommissioning. RAIN’s remit is to develop robotic and AI solutions to meet user-led challenges in the nuclear industry. A team of RAIN researchers has been working with DSRL to understand where our technology might benefit them.

3D Mapping with handheld sensors at walking pace

In the film Prometheus (2012) a team of astronauts explored the underground lair of the mysterious “Engineers” and used a flying device to quickly map the environment. Slightly less mysterious engineers in Oxford Robotics Institute have developed a handheld mapping device capable of mapping large facilities at walking speed.

RACE shares robotics expertise

Building networks between research and industry is a fundamental principle of the RAIN Hub. Early meetings between RAIN and Rolls Royce (RR) explored ways in which RAIN could support the short and long-term objectives of RR. In addition to collaborative projects and robotic deployments, sharing the expertise that RACE has in both designing for robotics and the long-term integration of robotics into regular operations was identified as valuable to RR. To this end, a series of four workshops were held between RACE and (RR) over the summer.

Remote Inspection Working Group (RIWG) trials in drummed waste store

As part of the RAIN project, the Remote Inspection Working Group (RIWG) has been developing a range of technologies to allow autonomous ground vehicles to characterise and monitor facilities that process and store waste from the nuclear industry. As part of this work, we have been developing a relationship with the UKAEA Waste Consignments team in Culham. In this relationship we have been working to understand the different requirements the UKAEA team have for autonomous systems in monitoring and managing temporarily stored waste, and helping them understand the technology currently under development in the RAIN consortium. As part of this process, UKAEA have allowed us to trial various robotic inspection systems in their low hazard drummed waste store in Culham.
