Finished the German Open? - check! Had fun? - check! Won the title? - well, check again.

Stay tuned for the release of the finale tomorrow. We played against B-Human and unfortunately lost 4-1. But hey, what was that? four to one (1)? Yes, we struck a goal and had 2 other major chances, but in the end it was just not enough. But does that mean we can turn the tides over the next three months? Only one way to find out, you know it!

We'll upload the final as soon as we can, we'll update you here, but in the meantime. Check out the entire German Open 2024 Playlist! [Link]

Semi Final - That's some high-risk heart attack stuff right there!

 

If playing against the HULKs is establishing itself as a new ritual, we probably all need a new cardiologist soon. Like in 2023, the game was full of suspense, robot-battling robots, laughter, groaning, shouting (at referees *cough) ... but goals, too? You will find out by watching the video ;)

You can count on the HULKs to deliver a really worthwhile and entertaining spectacle when we're up against each other! They are a great team that, no doubt, plays at our level and would beat us if we don't pay attention. You can watch the great development of our gameplay from 2008 till today - from searching the ball for 10 minutes straight to dribbling and passing across the whole field. With that, the matches mature and become more and more dynamic and in our match against the HULKs, we depended on every last thing we ever developed. And yet - right up until the end, you can never be sure: Will it have been enough?

A Rematch! A Rematch!

 

The news is out - last year's spectacular and nerve-racking semi final is bound to get a sequel!

Having fought our way through 5 group rounds, great ups and, well let's call them 'memorable' downs, we made the cut and the opponent du demain (well at least the first one, that is) could hardly be more thrilling and daunting at the same time: the HULKs from Hamburg. So we got our work cut out for us. We collected a whole lot of data with Eindhoven on our mind but that certainly doesn't mean that we're not going to try whatever is possible (and maybe even then some!) to win! If you, dear reader, can't remember the showdown battle royale of Bordeaux, check out the Youtube video I linked on the bottom of this post.

 

Living la Vida Loca

Well, it's a never ending story. In order to get where you want to go, you need to know were you are. Maybe even where you came from in the first place, but that's bonus information for reasonable people who have their life together and actually know how taxes work. For a robot, there are much more fundamental concerns:

• When do I turn my head and how fast?
• Where is the ball?
• Where am I and if I'm not alone - how many of me are there?
• Am I unique if and only if I occupy a unique agent state?
• What is love?
• Where is the ball?
• Baby don't hurt me.
• What is that line over there?
• Where is the BALL?

 We got into the finer details of localization logic. For instance, as I teased in the first blog post, we're now looking for the ball while getting up under external assumptions where the ball is most likely to be found. Robots that get a lot of action als tend to need a lot of time face down on the field - but falling can be messy and the NAO is not famous for its gracefully feline intuition. So what do? Well, in addition to our revised ball search after the fall, we've tweaked and calibrated various parameters when to - and crucially, when not to - look for the ball. A striker usually doesn't need to run all that quickly, as long as he's consistent; but more control could mean losing the ball less since dribbling would be more precise and we could avoid unnecessary ball-searches. A robot can spontaneously lose sight of the ball, and adjusting the window of blind trust can be pretty

tricky.

 Here the link to our last match against the HULKs, let's see if we can repeat that!

 

Last Game of the Group Phase: HTWK Robots vs Naova

The final match-up of the group phase put us up against the only non-European team that made its way all the way here to participate in the German Open! I'm of course talking about the Canadian team Naova from Montréal. Naova certainly had a good run this competition - even scoring a goal against the ironclad defenses of B-Human and almost wrangling the mighty HULKs. So there was certainly a sense of nervousness when the first half just wouldn't quite get going as we needed it to. There is no comfort in a 1:0 lead. Luckily, we were able to turn it around in the second half, but I won't give everything away. 

As a bonus treat: our team member Felix and Adrian from R-ZWEI KICKERS are giving commentary and insider knowledge in German - you won't get sound like this in the live stream!

Round 5 - The eternal rivalry reloaded reloaded reloaded reloaded reloaded

For this match we're facing B-Human against whom we've played so many times! Good thing that we just had a break by getting to skip round 4 via Wild Card. But don't worry, it wasn't realxing. More time is just more time to fix what can be fixed, improve what can be improved upon and leave alone what needs to be oh-my-god-don't-touch-it-it-works left alone. This time, however, it might seem like there could be light at the end of the tunnel? Are we getting closer to salvation or is it just a train speeding towards us? Let's us know what you think in the comments!

Round 3 - They are from Berlin, they are united, and they're our next opponent: Berlin United!

Some of our team members only know them from last year's RoboCup but they are a team with a great tradition. This year, they are back again and certainly a competitor not to be taken lightly

Round 2 - The Bots Are Bembling!

Watch our second match of the German Open against the Bembelbots!

We're at the German Open!

No Launchbreak For The Newbies

RoboCup season has begun and we're welcoming our new NAOs into our ranks: Curiosity, Dragonfly, Atlas, Hubble and Genesis joined us last year and made their HTWK Robots debut in Hamburg at the RoHow where we ceremoniously bestowed them with names and honors. In V6 tradition, they've all been named after spacecraft. But now it's time to take off the stabilizers and well, take off!

 

Lost In Translation?

Unfortunately, the inaugural game could have run a little smoother. In a flash of excitement, Hubble suddenly spent the the entire remaining communication budget in a matter of seconds - in minute 6 no less. Of the first half. Well, that hurt and there is certainly a parallel universe in which that didn't happen and we're all a little happier. But the Nao Devils delivered an astronomical performance in their own right!, although we managed to score the first goal, right after the disqualification was announced, the devil came down to Kassel and took the lead. And after that, well there was no coming back from that. Literally! Because once you exceed your communication budget, all your goals are immediately annulled and no further goals are counted. Could it have been a 3:1? Maybe, but we'll never know what would have happened had the things that did happen not happened. It happens! *Or what would have happened, if I wasn't trying to squeeze as many space references into this first part as possible - you know, like a black hole! But yeah, see for yourself:

Watch your step!

Being able to walk is nice and all - but wouldn't it be nice to als see where you're going? Well, we're doing that already but now we added a new dimension, while getting up, our NAOs stabilize in the final seconds, zeroing in on not falling back over (an infamous problem among virtually every time). But if a goalie get's up after diving in front of the ball, the ball is probably still right there in front of him! In the past, we had to discover that these were moments our oppents would readily exploit and we can't have that! So now not only does the NAO start looking while getting up, but he also starts where the ball is most likely to be! Sounds simple, but unsurprisingly, it has its pitfalls.

We know humanity's best friend but what does that mean for humanoid robots? Well you know where this is going! How cute are they together!

 

But the humans are also great, a robodog is just unfair competition. It's still wonderful, though, seeing everyone back in one place, hacking together, having fun, spending sleepless nights and just absorbing that community of passionate people!
