FET Award: STEM outreach at Luckwell Primary

This year, I have been lucky enough to receive a FET Award to promote STEM at a local primary school in south Bristol. Our key aims have been to use the expertise of UWE staff and students to deliver events which not only encourage children to pursue STEM careers, but also support teachers with some of the harder to achieve National Curriculum objectives.

Our first activity involved all students in Key Stage 2 – 120 in total. Inspired by the LED cards on Sparkfun, and ably assisted by fellow FARSCOPE students Hatem and Katie, we ran a lesson in which students used copper tape, LEDs and coin cell batteries to create a light-up Christmas tree or fire-side scene. Our aim was not only to show the students that electronics is fun and accessible, but to re-reinforce the KS2 National Curriculum objectives relating to electricity and conductivity.

Although a little hectic, the students really enjoyed the task and the teachers felt that the challenge of interacting with such basic components (as opposed to more “kid friendly” kits), really helped to drive home our lesson objectives.

To re-reinforce the Christmas card activity, we also ran a LED Creativity contest over the Christmas break. Students were given a pack containing some batteries, LEDs and copper tape and tasked with creating something cool.

Entries ranged from cameras with working flash  to scale replicas of the school. The full range of entries and winners can be found here. Overall, we were blown away by the number and quality of the entries.

Our second focus was introducing students to programming. To this end, we have been running a regular code club every Monday, this time supported by volunteers from UWE alongside FARSCOPE student Jasper. In code club, we use a mix of materials to introduce students to the programming language scratch. We currently have 16 students attending each week and recently were lucky enough to receive a number of BBC Micro bits.

Alongside Code club, we also ran a workshop with the Year 5 class, to directly support the national curriculum objectives related to programming. Students were given Tortoise robots (Built by FARSCOPE PhD students, in honour of some of the very first autonomous robots, built in Bristol by Grey Walter). Children had to program and debug an algorithm capable of navigating a maze.

As the outreach award comes to an end, we are planning a final grand event. Each year the students at Luckwell School get to spend a week learning about real-life money matters in “Luckwell Town”. During this week, students do not attend lessons – instead, they can choose to work at a number of jobs to earn Luckwell Pounds. This year, we will be supporting Luckwell Town by helping to run a Games Development studio. Students will use Scratch to design and program simple games for other students to play in the Luckwell Arcade.

As with our prior events, the success will depend on volunteers from UWE donating their time and expertise to support us.

Luckwell Town will take place every morning of the week commencing June 12th. We are looking for volunteers to support us, so please respond to the Doodle poll if you are interested.

An Ethical Roboticist: the journey so far

What do robots have to do with ethics? And how do you end up with the job of “roboethicist”? Prof. Alan Winfield, Director of the Science Communication Unit at UWE Bristol, explains his recent professional journey.

It was November 2009 that I was invited, together with Noel Sharkey, to present to the EPSRC Societal Impact Panel on robot ethics. That was I think my first serious foray into robot ethics. An outcome of that meeting was being asked to co-organise a joint AHRC/EPSRC workshop on robot ethics – which culminated in the publication of the Principles of Robotics in 2011: on the EPSRC website, and with a writeup in New Scientist.

Shortly after that I was invited to join a UK robot ethics working group which then became part of the British Standards Institute technical committee working toward a Standard on Robot Ethics. That standard was published earlier this month, as BS 8611:2016 Guide to the ethical design and application of robots and robotic systems. Sadly the standard itself is behind a paywall, but the BSI press release gives a nice writeup. I think this is probably the world’s first standard for robot ethics and I’m very happy to have contributed to it.

Somehow during all of this I got described as a roboethicist; a job description I’m very happy with.

In parallel with this work and advocacy on robot ethics, I started to work on ethical robots; the other side of the roboethics coin. But, as I wrote in PC-PRO last year it took a little persuasion from a long term collaborator, Michael Fisher, that ethical robots were even possible. But since then we have experimentally demonstrated a minimally ethical robot; work that was covered in New Scientist, the BBC R4 Today programme and last year a Nature news article. I was especially pleased to be invited to present this work at the World Economic Forum, Davos, in January. Below is the YouTube video of my 5 minute IdeasLab talk, and a writeup.

 

 

To bring the story right up to date, the IEEE initiated an international initiative on Ethical Considerations in the Design of Autonomous Systems, and I am honoured to be co-chairing the General Principles committee, as well as sitting on the How to Imbue Ethics into AI committee. The significance of this is that the IEEE effort will be covering all intelligent technologies including robots and AI. I’ve become very concerned that AI is moving ahead very fast – much faster than robotics – and the need for ethical standards and ultimately regulation is even more urgent than in robotics.

 

It’s very good also to see that the UK government is taking these developments seriously. I was invited to a Government Office of Science round table in January on AI, and just last week submitted text to the parliamentary Science and Technology committee inquiry on Robotics and AI.

The story behind the cameras: filming robots

In 2013, just as I was finishing my Masters in Science Communication at UWE Bristol, I was asked to help film the euRathlon robotics competition in Germany. euRathlon was inspired by the situation that officials were faced with after the nuclear accident in Fukushima in 2011. The competition challenges robotics engineers to solve the problems of dealing with an emergency scenario, pushing innovation and creativity in the robotics domain. The project is led by Prof. Alan Winfield from UWE alongside seven other partner institutions. The 2015 euRathlon competition in Piombino, Italy combined land, sea and air challenges for the robots to overcome. Our 2015 film team included three of us (Josh Hayes Davidson on graphics, Charlie Nevett on camera and myself – Tim Moxon – as producer and sound engineer), taking with us all the lessons I learned from 2013.

Filming robots, particularly complex robots designed to respond to emergency scenarios, is a daunting task. Trying to make sure that we didn’t get too technical was always going to be a problem. We had the additional issue that English was not the first language of most of the people being interviewed which really added to the challenge. Taking care and with plenty of re-shoots we managed to get round both of the problems by sticking to the golden rules: take it slow and keep it simple. This made sure that we never lost sight of what we were trying to do. Our focus was always to bring 21st century robotics into the public eye.Picture 2

The first two days of the competition presented the individual land, sea and air trials. On site we first created two “meet the teams” films where we interviewed all 16 teams and got to know them. Luckily they were all super friendly and very cooperative which meant we got all the teams interviewed in two days. After that the real work began. The land trials were easy enough to film and get a good story line of shots as the robots were almost always visible.  However the underwater robots required a bit more imagination. In the end a GoPro on a piece of drift wood got us the shots we needed.


The aerial robots had some issues too as getting long distance shots was not always easy. Fortunately Josh and Charlie were more than up to the task.

Day 3 and 4 focused on combining two domains, so land and sea or air and land etc. Day 3 went well with fantastic interviews with judges and teams helping to really give some depth to the videos. Again underwater proved to be a bit challenging but we managed, with the help of some footage given to us by the teams that they took on-board their robots. Day 4 didn’t go as well as the second half of the competition had to be cancelled due to strong winds. Wind had been an issue throughout the competition and all of our equipment required regular cleaning to keep the dust out, as well as dealing with constant wind when recording sound.

That day however you could barely stand in the open for all the dust and sand being kicked up by the wind and getting good sound for interviews was nearly impossible. We could only hope that the weather improved for the Grand Challenge.

The final days were the Grand Challenge, as much for us filming as for those competing. The timescale was starting to tighten as we only had two days to film, cut and polish the remaining two videos. With increasing pressure to produce high quality products we pulled out all the stops. Fortunately all the teams rose to the occasion and provided us with some spectacular on-board footage as well as some nice underwater diver footage. The Grand Challenge turned out to be a great success with all the teams at least competing even if they didn’t all finish the challenge.

Tim Moxon completed the UWE Bristol Masters in Science Communication in 2013.
