DETIhas announced key research highlights and results from the partners collaborating on the programme, developed to help UK manufacturers achieve engineering leadership and better sustainability.
Digital Nowpresents nine key research highlights; from a visualisation tool that displays carbon emissions, and an industry first with sustainable prototyping to a novel software system used to improve fault detection – these are just a snapshot of the digital technologies and research showcased.
The work of UWE Bristol research teams are featured, including our research into automating and digitalising the inspection process of composite materials using a novel software system and state-of-the-art machine learning techniques, and bringing digitalisation to the manufacturing process using immersive technologies such as augmented reality.
Neurodiversity Week celebrates our unique strengths and differences, while recognising that the many talents of people with ADHD, autism, dyslexia, dyspraxia and other neurodiverse ways of thinking and learning are often not suited to traditional, formal learning environments.
Science Hunters is a Science, Technology, Engineering and Maths (STEM) outreach and research programme that uses Minecraft to engage children from under-represented groups with STEM. Projects have covered a wide range of topics such as the Amazon rainforest, understanding diabetes, earth science and volcanoes and space, with the Building to Break Barriers project currently running at UWE Bristol engaging children with many aspects of engineering.
Minecraft is the second-best selling video game of all time and extremely popular with children. Players place and break blocks with a wide range of appearances and properties, to build a huge range of constructions. It can be played either as a single-player game or in a shared virtual world with multiple users playing together, and was chosen for Science Hunters because of its popularity (children want to play it!), particular appeal to children who learn differently, and suitability for explaining science.
A key target group for Science Hunters is children with Special Educational Needs (SEN), particularly through a dedicated Minecraft Club that has been running since 2015. It soon became clear that taking part in the club, alongside children with similar needs in an accepting environment, and playing a game which was a shared special interest, had more benefits for participants than STEM learning alone.
When face-to-face sessions are possible, as they were until the onset of the COVID-19 pandemic, Minecraft Club uses a dedicated server, so that children can play together in a safe social online space. Most of the children who attend have ADHD, autism and/or dyslexia. Spaces are limited to no more than 16 at a time, with simple guidelines to keep the club fun; children are not under pressure to conform to ‘neurotypical’ behaviour norms as may be expected in non-specific settings.
STEM topics are briefly introduced, and then participants are free to build in Minecraft in relation to that topic; while adults are there to guide and support, children are encouraged to follow their own interests and ideas to create their own unique designs. For four years, data were collected from participating children and their parents/carers, who attended with them, through surveys and interviews.
During this time, 101 children aged 5-17 years attended; responses were gathered from 29 children and 37 caregivers. Results indicated that children both enjoyed and learnt something from attending, and while their feedback understandably often focused on Minecraft, they also indicated that they had benefitted socially and emotionally from being in the shared space with other children with similar interests. This was supported by insights from parents and carers, who described benefits outside the club, such as improved confidence and wellbeing, improved social skills, and reduced need for formal learning support.
Interest in playing Minecraft is what motivates children to attend, and the game provides a range of opportunities for children to potentially develop social and educational skills. This is supported by the process of designing and completing builds, independently or collaboratively, and communicating with others within the shared virtual world. Playing in the same physical space enhances this, as communication can move between the virtual and real worlds and allow in-person peer support and the ‘safe space’ provided in our Minecraft Club supports children with SEN to interact naturally and spontaneously. While it was set up as part of STEM outreach, the social communication impacts of our Minecraft Club – such as making friends, fitting in, and feeling valued without judgement regardless of completing tasks or conforming to expected social behaviours – are at least as important.
Minecraft Club is currently running virtually as part of Building to Break Barriers. We’ve looked at earthquake-proof buildings, protecting against flooding, tunnels, drones and more, and are exploring the effects of the change to meeting online.
In an effort to build back better from COVID-19 and support innovative new enterprises, the government has announced funding to support projects harnessing the latest technology to support the fight against COVID-19 and other global challenges like climate change.
Dock-to-Dock focuses on the combined aspects of route development, vehicle performance (air & sea) and the associated infrastructure (‘Smart-Multiports’) required for point-to-point delivery of goods and freight between coastal cities using eVTOL aircraft (electric Vertical Take-Off and Landing) and eAZE ships (electric Autonomous Zero Emission).
The project will launch on December 1st 2020, and will initially look at the delivery of goods by air, between Avonmouth Docks in Bristol and Cardiff Docks in Wales, using electric aircraft which take-off and land vertically, and therefore don’t require runways.
The objective of Dock-to-Dock is to repurpose port infrastructures to be an essential component of future Smart Cities in their drive towards zero emissions and energy efficient, integrated and sustainable transportation solutions. It will demonstrate a commercially competitive alternative to ground transportation between the two cities, offloading the already saturated ground transportation network between ports such as Swansea, Cardiff, Bristol and Bridgewater.
A team of four UWE researchers will deliver on the use case definition and evaluation, route characterisation and eVTOL assessment activities for the Dock-to-Dock project. State-of-the-art modelling and simulation knowledge and methods, nurtured within the Engineering Modelling and Simulation Group and the Centre for Transport and Society, will be employed to ensure the success of the study and future implementation of the concept. Both research groups are proud to be part of the UKRI Future Flight Challenge and be able to contribute towards more sustainable future of aviation.”

With further development, Dock-to-Dock and its Smart-Multiport infrastructure could be a major supplier of Green Hydrogen to Bristol, Cardiff and Swansea airports, a service eagerly awaited by commercial aircraft designers such as Airbus and Rolls Royce who are racing to develop Hydrogen-powered sub-regional aircraft.
Presently there are only 11 commercial Hydrogen Refuelling Stations in the UK, and none west of Swindon. Many more are urgently needed if the UK is to meet its zero emissions targets through the production and use of Hydrogen in heating, industry, power generation and transport. The Dock-to-Dock project and development of Smart-Multiport infrastructure will bring much needed access to Hydrogen Refuelling Stations in the South West of England and Wales.

It comes at a perfect time as we prepare to open our new engineering building where we will have state-of-the-art digital engineering facilities and an increased focus on digital engineering to train our graduates for emerging roles in the sector.”
With all the fantastically fascinating research going on in Engineering, Design and Mathematics, PhD student successes are a regular occurrence. We want to celebrate with the students as they pass their vivas, so may this post be the first of many!
Adriaan Van Niekerk passed his PhD viva in early February – Congratulations Doctor Van Niekerk! He’s kindly answered a few questions about his PhD project…
Can you summarize your research project?
I looked at how we can reduce
diesel car emissions such as NOx by using fuel blends between diesel, biodiesel
and ethanol and also increase the renewable content of the blend as per the
government targets. I found that a fuel blend containing 2% biodiesel and 9%
ethanol can reduce NOx by 10% and CO by 34%.
What outcomes have there been from your project?
I managed to publish my results
in two high impact journals, Applied Energy and Fuel, which is really great!
Were there any particularly tough stages during the PhD? How did you get through that?
The engine I used to do all my experimental testing on decided to break. All four of its fuel injectors got blocked up. It took me really long to figure out what was wrong with it, and it set me back approximately 6 months!
This was really tough as I had to change my planning completely. Luckily I could focus on writing up most of my PhD which helped a lot at the end as most of the writing and reviewing was done.
What are your plans now the PhD has finished?
I have accepted a Lecturer position here at UWE with the Mechanical and Automotive cluster. I hope to build on my PhD research by looking at using renewable fuels together with hybrid technologies to speed up the uptake of more sustainable technologies for propulsion in automotive and aerospace applications.
UWE Aerospace’s Steve Wright has been popular in the news this month, most recently reassuring local Bristol businesses, Rolls Royce and Airbus, with his predictions of recovery after Covid-19. Read Steve’s expert opinion on how the pandemic will effect the aviation industry.
Technology from the Centre for Machine Vision (CMV) has been making moves to improve animal welfare and maximize crop harvesting.
First off, the 3D imagery system, Herdvision, that helps farmers assess cows’ wellbeing, was featured on the BBC six o’clock news in 2019 as it began a trial by Arla UK 360 farmers.
The technology developed in collaboration with Kingshay and AgsenZe, uses visual monitoring, data recording and automated intelligence to identify changes in each cow’s physical wellbeing, mobility and weight, before they are visible to the human eye.
Facial recognition used to assess pig’s emotions
Animal behaviourists from Scotland’s Rural College in Edinburgh, are using the technology provided by machine vision experts at UWE, to picture a range of pig facial expressions. The hope is that emotions can be identified and facial recognition used to improve pig welfare.
The BBC reported on the study in spring last year and the work is due to appear as part of a Netflix program in 2020.
The potato harvester based data capture system –Harvest Eye – provides insight on size, count and crop variation on unwashed potatoes as they are harvested. The integrated data analytics shows precisely what is being lifted and from where in the field, insights that will help maximise marketable yield and reduce crop imbalance.
The technology’s utility was recognised at the Potato Industry Event 2019/20, when it picked up second prize (out of 15 nominations) .
Harvest Eye was developed by CMV for B-hive, who then patented the technology in collaboration with CMV, and now B-Hive / Branston have established a new company, HarvestEye Ltd, to supply the HarvestEye technology to Grimme,a major manufacturer of root crop harvesters.
But the team at CMV aren’t stopping there.
“We’re working on a new funding bid right now to add functionality.”
Melvyn Smith, CMV
Mark Hansen, who led development of the technology, represented CMV, as part of the team that picked up the award.
A new project studies how to investigate accidents with social robots, Alan Winfield explains why this is needed…
Originally posted on September 17th, 2019 by Alan Winfield on his blog.
Imagine that your elderly mother, or grandmother, has an assisted living robot to help her live independently at home. The robot is capable of fetching her drinks, reminding her to take her medicine and keeping in touch with family. Then one afternoon you get a call from a neighbour who has called round and sees your grandmother collapsed on the floor. When the paramedics arrive they find the robot wandering around apparently aimlessly. One of its functions is to call for help if your grandmother stops moving, but it seems that the robot failed to do this.
Fortunately your grandmother recovers but the doctors find bruising on her legs, consistent with the robot running into them. Not surprisingly you want to know what happened: did the robot cause the accident? Or maybe it didn’t but made matters worse, and why did it fail to raise the alarm?
Although this is a fictional scenario it could happen today. If it did you would be totally reliant on the goodwill of the robot manufacturer to discover what went wrong. Even then you might not get the answers you seek; it’s entirely possible the robot and the company that made it are just not equipped with the tools and processes to undertake an investigation.
Right now there are no established processes for robot accident investigation.
Of course accidents happen, and that’s just as true for robots as any other machinery .
Finding statistics is tough. But this web page shows serious accidents with industrial robots in the US since the mid 1980s. Driverless car fatalities of course make the headlines. There have been five (that we know about) since 2016. But we have next to no data on accidents in human robot interaction (HRI); that is for robots designed to interact directly with humans. Here is one – a security robot – that happened to be reported.
But a Responsible Roboticist must be interested in all accidents, whether serious or not. We should also be very interested in near misses; these are taken very seriously in aviation , and there is good evidence that reporting near misses improves safety.
First we will look at the technology needed to support accident investigation.
In a paper published 2 years ago Marina and I argued the case for an Ethical Black Box (EBB) . Our proposition is very simple: that all robots (and some AIs) should be equipped by law with a standard device which continuously records a time stamped log of the internal state of the system, key decisions, and sampled input or sensor data (in effect the robot equivalent of an aircraft flight data recorder). Without such a device finding out what the robot was doing, and why, in the moments leading up to an accident is more or less impossible. In RoboTIPS we will be developing and testing a model EBB for social robots.
But accident investigation is a human process of discovery and reconstruction. So in this project we will be designing and running three staged (mock) accidents, each covering a different application domain: assisted living robots, educational (toy) robots, and driverless cars. In these scenarios we will be using real robots and will be seeking human volunteers to act in three roles, as the subject(s) of the accident, witnesses to the accident, and as members of the accident investigation team. Thus we aim to develop and demonstrate both technologies and processes (and ultimately policy recommendations) for robot accident investigation. And the whole project will be conducted within the framework of Responsible Research and Innovation; it will, in effect, be a case study in Responsible Robotics.

In 2018, Women Like Me launched at UWE as a tiered mentoring project for women in engineering. Delivered by Dr Laura Fogg-Rogers and Dr Laura Hobbs, the project was a great success, engaging over 10,000 children with engineering outreach and significantly improving engineers’ confidence. Some findings of the first year’s project report are summarised here.
Only 12% of engineers in the UK are women. For democratic, utilitarian and equity reasons this is not enough. Both recruitment and retention are important – more girls need to connect with engineering as a creative, socially conscious, collaborative discipline, and more women need to be supported to make a difference in the workplace.
Funded in 2018-2019 by a Royal Academy of Engineering Ingenious grant, the ‘Curiosity Connections – Women Like Me’ project aimed to change this through tiered mentoring and role modelling. Previous research by Laura Fogg-Rogers indicates how important peer group and leadership support is for women, providing vicarious experience and changing social norms. This means that women need peer support to thrive in the workplace, and that girls need to see women succeeding in STEM careers in order to feel that engineering is for them.
This project therefore paired 21 mid-career (senior) women engineers with 21 junior women engineers (less than five years’ experience) in the Bristol and Bath area, in order to provide career and public engagement mentoring. The outreach activities resulted in over 10,240 children being engaged in public engagement with women engineers, through a variety of methods including school visits, public events and nationwide online presentations.
Junior engineers felt significantly more equipped to take part in public engagement
The junior engineers reported that they now feel significantly more equipped to take part in public engagement; 54% of junior engineers felt fairly well equipped before the project and this increased to 68% after the project, with 38% indicating they were very well equipped. Similarly, the mean score on the Engineering Outreach Self-Efficacy Scale significantly improved from 6.80 to 8.41 (out of 10). This indicates that the engineers are now much more confident to undertake education outreach, and are then more likely to continue public engagement following the project.
The report therefore concludes that mentoring is highly important to ensure a supportive workplace, which means that women are more likely to be retained in the engineering industry.
The full reportcan be downloaded from the UWE research repository and a paper in Journal of Science Communication, drawing on the results, is now available (open access).
Women Like Mewill relaunch in October 2019. To express an interest in taking part, please register your email address here.
This year, 6500 students from Universities across the UK took part in the challenge organised by EWB-UK. Fewer than 200 got through to the Grand Finals. The UWE team (Amelie, Marwan, Liberty, Conrad, Caner and Nicholas) were amongst the talented few. They presented their PEEPOWER inspired solution with much enthusiasm.
