BuGa 2023: TIGERs Mannheim vs. RoboTeam Twente

Soon the fifth and penultimate game of the day between TIGERs Mannheim and the Dutch team RoboTeam Twente will start. To be honest, we’re expecting a massacre with a clear victory for Mannheim.

First Half

05:00 Once again, the game is delayed by a few minutes, but this is hardly noticeable as the president of DHBW Mannheim gives a brief speech and introduction to the SSL League and our robots. It’s evident that he’s well-versed in the subject matter, and the introduction to our league and its challenges was very knowledgeable.
05:00 And again, the game starts with a timeout for Twente, but TIGERs gracefully passes the time with some dances, songs, and maneuvers, much to the delight of the spectators.
05:00 With about fifteen minutes, the game is finally kicked off, with TIGERs having the kickoff as the blue team.
04:49 Things heat up immediately, and TIGERs scores a goal, but apparently, the Dutch have luck on their side, as one of their robots touches the ball in their own penalty area just before it rolls into the goal, nullifying the goal.
04:39 Another strong situation in Twente’s penalty area, but once again, the Dutch have luck. However, this luck is unlikely to last forever.
04:20 This time, though! At first, it seems like bad luck as TIGERs loses the ball. But they quickly clear the situation in their favor and finish with a shot on goal. Initially, the goalkeeper seems to save, but then he turns the ball into his own goal!
TIGERs Mannheim 1 : 0 RoboTeam Twente
03:54 And again! Another goal directly by TIGERs Mannheim, making it 2:0 now!
TIGERs Mannheim 2 : 0 RoboTeam Twente
03:03 Another hot shot, but one of the Dutch robots clears through a foul: He positions himself in the defense area and defends with his body.
02:57 However, the defense doesn’t hold for long, another goal by TIGERs!
TIGERs Mannheim 3 : 0 RoboTeam Twente
02:25 The Twente goalkeeper, the strongest man on the team. He can actually prevent goals quite confidently, even though he may face minor mistakes and the dominance of TIGERs, he won’t see the sun in the long run.
01:42 Good ball exchanges and nice duels, mostly in Twente’s half. But in the end, as in most of this game, it happens: a goal for TIGERs!
TIGERs Mannheim 4 : 0 RoboTeam Twente
01:09 Now TIGERs steps up! Another goal by the Mannheim team!
TIGERs Mannheim 5 : 0 RoboTeam Twente
00:48 And again… a goal for TIGERs, the celebrated devastation is in full swing, the team firmly in the grip of the Tiger’s jaws.
TIGERs Mannheim 6 : 0 RoboTeam Twente
00:11 For a while, the ball was even in Mannheim’s half, but then, as always, it goes as expected: TIGERs can regain possession of the ball and tighten the noose even further. Eventually, TIGERs increases the lead to 7 goals.
TIGERs Mannheim 7 : 0 RoboTeam Twente

Second Half

05:00 The second half starts directly with a penalty for TIGERs, as it seems Twente committed a foul at the end of the first half (again, a Twente robot touched the ball in the penalty area).
04:53 And TIGERs naturally converts the penalty, extending their lead to 8 goals.
TIGERs Mannheim 8 : 0 RoboTeam Twente
04:37 And immediately, the next goal. Now only one more is needed to end the game prematurely.
TIGERs Mannheim 9 : 0 RoboTeam Twente
04:14 And with that, the game ends prematurely: TIGERs scores the last goal of the match and secures the top spot in the group.
TIGERs Mannheim 10 : 0 RoboTeam Twente

BuGa 2023: Immortals vs. TIGERs Mannheim

Actually, the second game of the day between Immortals and TIGERs Mannheim is scheduled for 11:30 AM. However, unfortunately, Immortals are not even in Germany yet due to a delayed flight, and as a result, they automatically forfeit their match with a score of 10:0.

Very unfortunate, as Immortals are an extremely strong team, formerly Iranian and now German, which showcased a very impressive performance at RoboCup. Together with TIGERs Mannheim and us, they form a quite evenly matched group at this tournament, and predicting the outcome of the games between these teams is not trivial.

Let’s hope that Immortals can make it to their next game and can build on their successes from RoboCup!

BuGa 2023: ER-Force vs. TIGERs Mannheim

Now it’s finally time: The tournament at the Bundesgartenshow 2023 officially begins with the first match of the group stage: ER-Force vs. TIGERs Mannheim.

We’re incredibly excited about the game, as we were able to achieve very positive results with our robots during the course of yesterday and this morning: While our new radio system had significant issues at RoboCup, the tests looked extremely promising yesterday evening. Together with the HBC team, the manufacturer of our radio system, and with the support of Gerhard Schubert, we made significant progress in the last two weeks. Everyone involved has put in many hours to push the radio system to the level of perfection we were used to from INTERPACK 2023 in May. The HBC radio worked perfectly there, completely unaffected by the numerous trade show Wi-Fi networks and Bluetooth devices.

Important note: Unlike RoboCup, all games at Bundesgartenshow are played with walls (bande), which means there are no out-of-bounds. This is an experiment by the organizers to see how well it works. We can expect very fluid games since out-of-bounds is the most frequent game interruption.

Since there’s unfortunately no livestream, the game will be provided as a video later.

First Half

05:00 The game starts with over 10 minutes delay, which is usually the case for the first game of the day and the tournament.
05:00 Unfortunately, a larger part of the first half could not be ticked due to personnel reasons. We’re currently limited in staff. As far as possible, the ticker will be updated. Unlike RoboCup, we have only 7 people for this tournament, which is definitely too few. Still a good experience: We estimate that we could fill all personnel gaps with 10 – 11 people, which is valuable for future tournaments. However, it doesn’t reduce the stress of this tournament.
02:30 So far, a very fluid game. A positive point to note is that our HBC radio can finally unleash the potential that it has. The robots are moving very smoothly, following their commands! We are currently playing with 4 new and 2 old robots.
01:00 Own goal by us! That’s unfortunate, it could have been avoided and must definitely be considered as part of our strategy, but there’s nothing we can do about it now.
ER-Force 0 : 1 TIGERs Mannheim
00:26 Very dangerous situation in our half. But in the end, our goalkeeper clears it to the right side, defusing the situation.
00:06 So far, a very fast and fluid game, which is, of course, due to the walls (bande) being used, resulting in no out-of-bounds.
-01:27 The game was quite balanced towards the end. Since the game is no longer interrupted due to out-of-bounds, it’s running for a long time, and now it’s stopped only because of a crash and the first half is whistled. Overall, it’s nice to watch; the decision against out-of-bounds adds a lot to the entertainment value for the spectators.

Second Half

05:00 Kick-off for the second half.
04:24 Yellow card for TIGERs, as they have accumulated three minor fouls during the game (they held the ball with the dribbler for too long twice and caused a crash at the end of the first half). Meanwhile, we’re replacing a robot.
04:24 Currently, there seem to be some minor issues with the network, causing the game to pause. During matches in our league, a central computer continuously receives camera data, processes it, and sends the resulting robot positions and velocities, along with referee commands and other information, via the local network to the team PCs, which then derive their game decisions from it and send them to the robots via radio. Therefore, a faulty network is a major problem for the game.
04:24 Apparently, the RefBox has also been successfully destroyed: The RefBox is a piece of software into which the human referee can input decisions, and where all decisions of the AI referee come together and are more or less clearly displayed. It seems that an attempt is being made to roll out a very old version of the RefBox, in which the “Game Controller” (the person supporting the referee who sits in front of the RefBox) has to manually input all commands, something that has been banned for years. Long-time members still have muscle memory for operating the old RefBox via the number pad, but the younger ones groan about the “Stone Age technology”.
04:24 Other than that, a brief update: Nothing has been broken so far; our hardware is running flawlessly, especially the new robots. So, in this area too, we’ve made significant progress compared to RoboCup. The one robot that was replaced was an old one and even it was driving a bit crooked, but didn’t show any serious issues.
04:24 The game continues, but ER-Force immediately takes a timeout. Apparently, our software doesn’t have the new radio system perfectly integrated yet, causing the software to occasionally lose the connection. Had to restart briefly, now everything is running smoothly again.
05:00 Apparently, they restarted the time after changing the RefBox.
03:48 Dangerous duel near our goal with a TIGERs bot, but we can clear the ball again.
03:35 Interruption of the game after TIGERs kick the ball out of the field towards the audience! Good thing they’re already one and a half meters above the field behind a railing.
03:05 After some good passes by TIGERs, one of their robots messes up the reception, much to our delight!
03:00 TIGERs’ yellow card has expired, so we’re back to playing 6 vs. 6.
02:22 Good situation for us in Mannheim’s penalty area, but their goalkeeper can clear it.
02:06 Another nice situation in TIGERs’ goal.
01:35 And right away, the attack in front of our goal, but our defense stands strong!
00:45 This time the ball goes out of the field through us. Playing with walls is new for both teams, not everything is smooth yet, especially in connection with the edges of the field.
-00:14 And the game ends 1:0 for TIGERs Mannheim with an own goal from us. As usual, TIGERs Mannheim ends their game with a victory dance, this time including the Cantina Band and a little dance.

In retrospect, it was a very nice game and much more to our liking! Everything went smoothly, the radio worked brilliantly, the hardware functioned perfectly. Of course, there’s always room for improvement, and that must also be the aspiration, but still, we can be very satisfied with the game. This will definitely be an exciting tournament!

Test Tournament in Mannheim

And once again, our team is continuing at high speed this year! Hardly have our guests from Uruguay returned to their home country, and we’re already moving forward in with a test tournament hosted by the world champion TIGERs Mannheim and their Dual University Baden-Württemberg as part of the Bundesgartenshow 2023 in Mannheim.

And so it’s already 07:54 AM for us at Erlangen Central Station, as we’re off to Baden-Württemberg, this time only using regional trains and the Germany Ticket for cost reasons. Surprisingly, there are no train delays, and by 1:00 PM, we can enter the sacred halls of the BuGa.

As with all our other trips, the first order of business in Mannheim is: Arrive, unpack, and start. It doesn’t take half an hour before the entire space provided to us is occupied with various equipment, chargers, and soldering irons.

Soon, the field for testing should be available, allowing us to make our robots operational. But first, it’s about being patient and settling in: Welcome to BuGa 2023 Mannheim!

PS: A fun fact on the side: We’re accommodated on the BuGa premises in the hall for “Beneficial Organisms and Pests.” No, we’re not pests; instead, they’re referring to the wall’s artwork. There simply wasn’t space for us in other halls.

RoboCup: Final Report

Now that the RoboCup is already a few days behind us, we’d like to take the opportunity to review the tournament.

Overall, our team was very well prepared, having all the electronic and mechanical components with us, allowing us to respond adequately to every situation with our equipment.

While it’s unfortunate that we ultimately lost due to our radio communication, everyone is already looking forward: Our sponsors Gerhard Schubert and HBC-radiomatic are already offering to address the existing issues with the radio system, so we can soon showcase our full potential.

We’re also looking ahead: Not only are we preparing for the arrival of a team from Uruguay at FAU at the end of July for a joint workshop, but we’re also planning improvements. While nothing works without radio communication, our motor boards have also posed problems. A robust solution needs to be in place by Christmas.

There was a small moment of joy at the end of the tournament: We quickly had the opportunity to take a photo with our friends from TIGERs Mannheim to compensate for the missing match against them.

In the end, we’re happy that the vacation, apart from the unfortunate theft of personal belongings, went very well, and everyone enjoyed it. The wine museum in Bordeaux, the beach holiday on the Atlantic Ocean, or the French National Day in Paris: Many beautiful moments will remain in our team’s memory, making our time together truly unforgettable.

So, there’s only one thing left to say: See you all in Eindhoven 2024!
