Day 7 – The End in Penalty Shootout

How does a tournament day start? Just like any other: breakfast – more swallowed than enjoyed – grab your bag, step into your shoes, and head off to the venue. At this point, we could walk the route in our sleep. Still, the mood was good – full of energy, because the first match of the day was coming up. Focus on, tunnel vision engaged, everything aligned for the match against TIGERs Mannheim.

ER-Force vs TIGERs

And the match? Surprisingly solid. Sure, we lost 0:5 – but that score doesn’t tell the full story. We played way better than in our first game against them. Managed some real attacks on their goal, had much more presence in their half. Overall, it felt structured, stable, clean. A huge improvement – and it showed.

Then about two hours until the next match. A proper team meeting: what worked, what didn’t, who’s doing what. Then we got to work. The venue was as hectic as ever – people fixing, coding, testing. The match before ours – ZJUNlict vs RoboCin – ran long, so we didn’t get on the field until right before kickoff.

The game against RoboDragons was tough but intense. We took an early 1:0 lead – quick moment of hope. Then the equalizer: 1:1 due to an own goal. A chip bounced off our own centerback and deflected straight toward the goal. It happens. The match went into overtime – and eventually to a penalty shootout. Sadly, we lost.

Naturally, the mood after that was subdued. No one really knew what went wrong. We had barely changed anything since the last match. One possible explanation: maybe the vision system was adjusted for another team’s robots at some point and never switched back. Whether that was the reason? Hard to say. But that’s part of the game – learning to deal with stuff like that.

The rest of the evening was more relaxed. We watched some matches, chatted with other teams, repaired a few things here and there. And then, of course: the open TC/OC meeting – another late night in the hall until 10 PM.

Some ended the day with a walk on the beach, others crashed straight into bed – completely wiped.

Day 5 – Early Start, Lots of Stress, and Broken Encoders

After a good breakfast, we headed out a bit earlier than yesterday – since yesterday we arrived too late at the hall. This time we were on time, and the stress kicked in right away: charging batteries, calibrating robots, prepping covers, testing encoders… At 9 a.m. (local BRA time), we already had our first match against TIGERs.

Overall, the game went okay – especially the first half. Even though we were down 4:0 at that point, as our first match of the tournament, and against the TIGERs no less, it was a solid start. Particularly frustrating: in the last 45 seconds of the second half, we conceded three more goals. Ouch.

In the team meeting afterward, it quickly became clear: our encoders were causing trouble. Untested battery and encoder mounts had damaged some cables, which led to faulty data. Some voltage levels (3.3V) also dropped intermittently – another encoder issue. On top of that, we were getting frequent fouls during kickoffs.

 

1.Spiel: ER-Force vs TIGERsOur quick (and pretty much only) solution: we heavily reinforced the broken encoder cables with duct tape. That was all we could do, since we only brought a limited number of spare parts. The electronics crew is now trying to recycle broken encoders and build new ones from the parts.

 

The rest of the day was filled with fixing, testing, and more fixing – but it paid off. We made noticeable progress and even took on our first official roles in the group stage.

One highlight: We got to use HWTK’s gimbal and managed to shoot some pretty cool clips of daily team life. There might be a little video coming soon!

As always in the evening: everyone on the team shares what went well and what didn’t. After that, another team meeting to get everyone up to speed. We also put together a game plan for tomorrow – it’s going to be intense: three matches, two ref duties. Pure stress.

Oh, and the betting game is back on too! Let’s see who’s got the best gut feeling this year.

Day 4 – Frustration and Progress

ER-Force on their way to the venue

The day started, as usual, with a hearty breakfast – a small ritual that brings some structure to the morning. Afterwards, we walked to the venue along the beach, enjoying a brief moment of calm before things got intense. Once inside the hall, everyone immediately got to work – the task distribution had already been set during the previous evening’s team meeting. Whether charging batteries, calibrating bots, or preparing systems, everyone knew their role. Time was short, as our first pass challenge match against Tigers was scheduled for 12 PM local time.

Unfortunately, things didn’t go smoothly. The downlink (Rückkanal) wasn’t functioning properly on the Funkmaster, the robots’ encoders – extra lines from the motors to the firmware that report wheel positions – were unreliable, the kickers failed, and even field testing didn’t run as expected. The result: both pass challenge matches against Tigers and ZJUN went poorly. We ended up in third place – last, although only three out of five teams participated.

Technical challenge vs TIGERs

Another challenge: this year’s carpet is extremely slippery, which made dribbling significantly more difficult. Ball control was noticeably worse compared to our usual testing conditions.

After the matches, the entire team shifted into bug-fixing mode. The downlink was finally fully implemented – too late for the challenge, but a big step forward nonetheless. From this point on, testing our software directly on the field became much easier.

We had another test slot in the evening, during which we intensively tested all the fixes from the day. Many bugs seem to be resolved – for example, the bots are now overshooting less. It feels like we’re slowly getting back on track.

School Visit – Willstätter-Gymnasium in Nuremberg

On Friday, May 9th, 2025, we – Robotics Erlangen – had the pleasure of visiting the Willstätter-Gymnasium in Nuremberg. Starting at 2 p.m., we had the fantastic opportunity to engage with students from all grade levels as part of the school’s Forschungs-AG (Research Club) – including a dedicated Robotics group of 5th graders who are just beginning their journey into technology and programming.

With us: two of our autonomous soccer robots, which we regularly use in national and international competitions. The students’ excitement was immediate – many were fascinated by how our robots can “understand” the field, orient themselves, detect the ball, and aim for the goal – all without any remote control.

In addition to presenting our work and giving insights into robotics at the Faculty of Engineering at FAU Erlangen-Nuremberg, students were especially curious about the technical details:
How do robots “think”? What’s behind camera-based object recognition? How are movements planned? And how do the robots communicate with one another?

At the same time, we were truly impressed by the students’ own projects within the Research Club. One highlight was a sustainable garden irrigation system, designed to be both ecologically and energy efficient. Automated, power-saving, and environmentally conscious – exactly the kind of innovation we need for the future!

We’d like to sincerely thank the Willstätter-Gymnasium for the invitation and the inspiring exchange. It was wonderful to see so much curiosity and creativity among the next generation of young researchers. We’re looking forward to seeing some familiar faces again – perhaps soon at FAU!

German Open 2025

March has arrived, and as every year, it’s time for tournaments. Next week, 14 of our members will participate in the Freizeit-Messe in Nuremberg. The fair itself runs from March 12 to March 16, but our games won’t start until March 13. The German Open, a major robotics and AI tournament held as part of the Freizeit-Messe in Nuremberg, gives our members the opportunity to showcase their skills in exciting competitions.

By the way, the Schubert Cup will also take place in Crailsheim from March 21 to March 23, where you can find us as well!

In addition to us, TIGERs Mannheim, Immortals, and SeeGoals will also be participating in German Open. Moreover, from March 11 to March 13, the Embedded World will take place—another great reason to stop by. The Embedded World Exhibition & Conference is the international industry meeting point for the embedded community, bringing together leading experts, companies, and associations while offering deep insights into the world of embedded systems.
