Guest blog Dr Daniel Polani, Adaptive Systems Research Group
We had played seven matches against the likes of Hamburg, Brazil and Indonesia and it was now time to face Japan’s CIT Brains in the final.
It was tough as the Japanese team took the lead scoring three goals and we thought it was going to be a walkover of the Germany vs. Brazil kind. However, our robots fought back and we managed to score twice before the whistle blew. It seemed that our robots were better on the long run and had the game gone on longer, we might have equalized. But it was an exciting game, with a final score of 2:3 to the new world champions.
We are delighted to have got to the final, which follows on from our 2nd place at the RoboCup German Open (April 2014) and 3rd place at the RoboCup Iran Open (April 2014). I’d like to thank everyone for their support and I am delighted to say that Bold Hearts is Vice World Champion in RoboCup Kidsize Football!

Our semi-final at the start of Day 4 was against EROS, a strong team from Indonesia.
After only 40 seconds, we scored the first goal, then a nicely placed second goal from the right flank. But EROS came back with their powerful kick, and scored a goal from a distance.
The rest of the game looked more like wrestling than football, as our Bold Hearts robots became "tired". We're not clear what the reason is yet, whether it's failing batteries, or loosened screws.

But the Bold Hearts stood up to EROS well enough, and managed to defend the score.
The final score was 2 - 1 to Bold Hearts!
And now we are in the FINALS of the RoboCup 2014 Kidsize Humanoid League!!
Guest Blog by Dr Daniel Polani, Adaptive Systems Research GroupFantastic news from Brazil! Bold Hearts, the University of Hertfordshire's robot football team, progressed through round 2 of the RoboCup World Cup, to the quarter finals, then winning that game to make it through to the semi-finals!
|Bold Hearts in Brazil|
We won our first game 3 – 1 against RoboFEI-HT, from Brazil. And then lost 0 - 4 against CIT, from Japan, who was placed 4th last year. And, amazingly, we only scored one own goal!
Perhaps we could have scored a goal for ourselves if the ball had not rolled away from our robot due to the uneven surface of the field - so the result is much less clear than it looks.
This was an encouraging result for Bold Hearts, as it means that we are really edging towards being able to match the best opposition. In fact, we thought this game looked more like real football rather than glorified billiard with opponent obstacles. CIT was a very strong team - but we still see potential for improvement for Bold Hearts.
Our third and final deciding game of round 2, was played on Day 3 of the competition against Hanuman KMUTT, a team from Thailand.
We needed to win this game to progress through to the quarterfinals – and we worked through the night on our robots before going out onto the field to meet the Hanuman KMUTT team.
The quarterfinal match against MRL, from Iran, was a highly contested, tight game with lots of man-to-man (or in reality robot-to-robot!) fighting.
But our opponent, MRL, was experiencing similar problems as us - with their robots sometimes turning to face in the direction of their own goal.
We ruthlessly exploited the opportunity, but they came back with some dangerous attacks - one particular one was made easier for them because our goalie was taken out for being classified as an "incapable goalie". The goalie must react when the ball is nearby, and our one didn't. So MRL went on to score an easy goal! MRL robots are faster than ours but sometimes they overshoot...
But the crowd cheered for Bold Hearts. And the final result was 3 - 2 to Bold Hearts.
We are delighted that Bold Hearts is through to tomorrow’s semi-finals, on Day 4 of the RoboCup competition!!
Wish us luck in the semi-final and that we score plenty of goals – in the opponent’s goal of course!

Guest Blog by Dr Daniel Polani, Adaptive Systems Research GroupRoboCup 2014 World Cup in Brazil started with an intermediate knock-out match with our old friends the Hamburg Bit-Bots from Germany. This game will decide if Bold Hearts will continue in the competition or not. We were looking forwards to this match, but had hoped it would be later in the competition. And as is tradition whenever we play, we expect to have a long and heated set of penalty shots!
We know Bit-Bots well, and they fielded an interesting, self-built team.
After a nerve-wrecking game, it was 2 - 2 at the end of full time. Then in extra time, we scored twice, winning this game 4 – 2 and going through to round 2! But Bit-Bots had some near misses!
And yes – you know it already - every single goal in our game was scored by Bold Hearts. So it proves that we are a good goal scoring team! Just not always in our opponent’s goal!
Our goal-detection system proved to be a problem. It had worked well in the trials and preparations before travelling to Brazil. However, there were a lot of visitors in the RoboCup venue on Day 2 of the competition, which may have changed the lighting a lot during the games - many of them were using cameras with flash during the games.
In addition, it did not help that one assistant referee was "streaking" – but not in the sense that we may know from other sports!
The assistant referee was walking barefoot which is strictly forbidden during games, as feet and legs often look like balls in the robot’s colour detection. Black trousers and covers were only put on after threats by the main referee.
Anyway, great news that Bold Hearts is through to the next round-robin part of the competition - round 2. So Bold Hearts has more games to look forwards to.
And we are further than ever before in at the RoboCup Kidsize World Championship!

Our first day of matches at the World Cup was filled with all the excitement that typically accompanies the Bold Hearts to the RoboCup!
|Bold Hearts in Brazil|
This was solved shortly before kick off when one of the network engineers increased the power output of our field's access point, but by this stage we no longer had enough time to run all the tests we needed to run before the start of the game. So our first game against TH-MOS started and semi-organised chaos ensued. The halls were quite dark and the goals difficult to recognise for the robots – so we had problems in goal detection.
At half time we were losing 2 - 0, but we did manage to score in the second half, losing 2 – 1 at the end of full time. Our problem of “Own Goalitis” struck again – as we had scored all three goals of the game – which was great for TH-MOS who didn’t manage to score goals for themselves and yet came out as the winners!
|Fields at the RoboCup World Cup in Brazil|
Overall we're really happy with scoring eight goals in two matches, losing one game and winning one. Although we would have liked all the goals to have been scored in the opposition’s goal!
But Bold Hearts is through to the next stage – an intermediate knock-out match with our old friends the Hamburg Bit-Bots!

A guest blog by Dr Ciara Meehan, School of HumanitiesOn 16 July, more than sixty delegates attended the three-day Perceptions of Pregnancy conference, organised by Dr Jennifer Evans and Dr Ciara Meehan of the School of Humanities.

The conference covered everything from conception to the birthing experience. Particularly striking was the paper from Anija Dokter (University of Cambridge) that featured sound-recordings of childbirth. The darker side of pregnancy was also explored and day two, for example, featured a panel on seduction, violence and supernatural hazards.
There were a number of timely contributions. Elaine Farrell (Queen’s University, Belfast) and Ciara Meehan (University of Hertfordshire) explored the stigma of being an unmarried mother. Both made reference to the recent scandal in Ireland, which attracted international attention following revelations that the bodies of up to 800 babies had been uncovered at the site of a former Mother and Baby Home in Tuam, County Galway. With recent campaigns for gender equality in both the British and Irish parliaments, Claire McGing’s (NUI Maynooth) paper, which gave recommendations on facilitating parenting for politicians, was particularly relevant.

Conference outcomes will include an edited collection and a special edition of Women’s History Magazine. Although the event is now over, the conference blog will remain active. Another aim of the conference was to build networks and facilitate further conversations, and we see the blog as an excellent forum for doing so. We hope to develop it into a space for the community of researchers working on pregnancy and its associated bodily and emotional experiences to engage, exchange ideas and highlight their work.
The conference was generously supported by the School of Humanities at the University of Hertfordshire, the Social History Society and the Royal Historical Society.

instrument that will go on NASA’s aircraft
This is what Aerosol Ice Interface Transition Spectrometer (AIITS) does and it is on show this week (1-6 July) at the Royal Society Summer Science Exhibition - which showcases the most exciting and cutting-edge UK science and technology.
|The AIITS mounted on the NASA aircraft|
As the particles enter the instrument, they pass through a beam of light - scattering the light into complex scatter patterns. The scatter pattern depends on the shape, size and orientation of the particles and is like a thumbprint which can be used to classify or even identify the particles.
|Light scatter patterns from various particles in the atmosphere|
Tropical storms in the West Pacific play a crucial role in the Earth's climate system. Starting above some of the warmest waters, they carry sufficient energy to punch through the boundary that separates the troposphere, the lowest layer in the atmosphere, from the stratosphere above. In doing so, they reach as high as 20km and carry air up from the Earth’s surface. Chemicals in the air reaching the stratosphere can lead to ozone depletion.
The exhibit is based on an atmospheric research campaign headed up by the University of Cambridge and involving the University of Hertfordshire and also NASA, USA.
The week-long Exhibition starts today (Tuesday 1 July) and is arguably the most prestigious of its type in the UK, attracting over 10,000 visitors; including secondary school students, policy makers, MPs, leaders of industry, and representatives from funding agencies. For more information, visit the Royal Society’s Exhibition website.
