RoboCup German Open 2025: ER-Force vs. TIGERs Mannheim

Posted on by

Now the time has finally come: The final match of the German Open will take place this Sunday at 12:30 PM between our team and the TIGERs Mannheim. After we were able to hold our ground quite well against the Mannheim team during this tournament, we can expect an exciting game here!

First Half

05:00 Both teams are preparing for the match. Our team is playing as the yellow team with—believe it or not—ELEVEN robots, while the TIGERs are in blue, of course, also with 11 robots.
05:00 The match kicks off on time at 12:30 PM with a kickoff for TIGERs. But right away, a timeout for ER-Force due to issues with Ra and the radio connection.
03:56 There are intense duels between the ER-Force robots and those of TIGERs in our half. Our robots are giving it everything they’ve got. The result: One of our high-kick flaps goes flying through the air!
03:41 Another very tense situation right in front of our goal. The ball keeps getting passed back and forth between our defense and the attackers, but our defenders ultimately manage to defuse the situation!
03:06 After some maneuvers in the Mannheim half, they strike back with a counterattack, unfortunately resulting in a goal from the side!
ER-Force 0 : 1 TIGERs Mannheim
02:33 The dangerous situations continue, but our robots are defending bravely so far. Both teams now have a yellow card, meaning only 10 robots are allowed to play!
02:17 Very well cleared by our goalkeeper! A throw-in by TIGERs near our penalty area turns into a dangerous attack on our goal, but the goalkeeper confidently defends with a chip kick.
01:35 This time, a small attack from our robots, with some of our field players showing great skills. Unfortunately, it does not result in a dangerous situation for the Mannheim team.
00:46 Our team is not showing any weaknesses: They relentlessly block every attempt to attack our goal.
00:23 A nice attack from our robots on the TIGERs’ goal, although the finishing power is lacking. The subsequent counterattack from Mannheim is successfully intercepted by our defense.
-00:02 The last attack from Mannheim on our goal, but it doesn’t pose a real threat. With that, both teams head into the five-minute halftime break.

Second Half

05:00 Without switching sides, the second half begins with a kickoff by ER-Force. Will our team manage to equalize?
04:42 Strong defense by our goalkeeper! A powerful attack by TIGERs, but our goalkeeper clears the ball towards midfield!
04:37 But unfortunately, now: The immediate follow-up attack is successful, and TIGERs extend their lead to 2:0!
ER-Force 0 : 2 TIGERs Mannheim
03:46 The dominance of TIGERs is clearly visible: The ball spends most of the time in our half. Nevertheless, we are holding our ground; despite the two conceded goals, our defense has been very strong so far!
02:56 Our defensive wall is rock solid: As soon as TIGERs find an opportunity for an attack, the wall closes in front of our goal and eliminates any danger.
02:22 A nice attack from our robots, but once again, we lack the finishing power to be truly dangerous!
01:43 What a scene in our penalty area! One attack on our goal after another, but with luck and relentless marking, we manage to prevent any further damage!
00:53 Our goalkeeper is as strong as ever and does not give up his goal easily! Unfortunately, we receive a red card after accumulating two active yellow cards and getting another one. A shame, as the first of these yellow cards would have expired in just four seconds.
-00:15 After one last effort and an incorrect interruption by the AI referee, the game finally ends 2:0 in favor of Mannheim.

Looking back, this match was a beautiful showcase of the current state of the Small Size League. In a very fluid game, both teams demonstrated their skills brilliantly.

Although TIGERs Mannheim dominated the match throughout, we still managed to launch attacks from time to time and defended even harder. As a result, we are still very satisfied with the outcome and take away many insights and opportunities for improvement for the next tournament, which will take place next week in Crailsheim!

German Open: Review

Now that the German Open, the second April tournament, has come to an end, we would like to take a brief look back at the event.

Unfortunately, we couldn’t win a trophy at this tournament either, but we gained valuable insights into our system and were able to significantly improve it towards the end. We started the tournament on Wednesday with completely new motor drivers and the associated problems, but we gradually got a handle on them.

It’s a pity that our last game on Saturday against TIGERs Mannheim was just a friendly match: If we had performed the same way the day before against Immortals, the tournament might have ended quite differently. But no matter: With the experiences and measurement data we were able to collect from this tournament, we can now enter RoboCup 2024 stronger and hopefully win big prizes there.

But the tournament was not only valuable for us: TIGERs Mannheim, Immortals, and Tritons also surely gained valuable insights. It’s a shame that Tritons couldn’t play in the end. It seems there is still some work to be done before real games can be played. All the more helpful that they had many opportunities at the German Open to exchange ideas with our team members and those of TIGERs and gather helpful input on how to solve the upcoming problems.

And finally, the tournament also seemed to be well received by the spectators: On the final day, the field was surrounded by visitors during both our friendly match and the final, eagerly following the game’s progress. Time and again, some children started chanting “ER-Force” – to such an extent that we had to assure TIGERs that we had not paid any of the spectators to be our cheering squad.

So we leave Kassel with the firm hope of being able to visit again next year when it’s time for RoboCup German Open 2025!

German Open: Finale: Immortals vs. TIGERs Mannheim

Now it is finally time: The final match of the German Open between TIGERs Mannheim and Immortals will take place shortly.

The livestream can be found as always on the YouTube page of TIGERs Mannheim.

First Half

05:00 And the game begins. TIGERs will play in yellow, while Immortals is the blue team.
04:25 After the ball was briefly in the TIGERs’ half, the tide quickly turns, and TIGERs begin a counterattack. This ends in Immortals’ goal, putting TIGERs ahead by one goal.
Immortals 0 : 1 TIGERs Mannheim
04:14 Another shot at Immortals’ goal, but this time the team can save it.
03:51 The pressure on Immortals does not let up. One shot on goal follows another, and at first, the defense holds. But eventually, it’s time: Goal for Mannheim!
Immortals 0 : 2 TIGERs Mannheim
03:34 That was somewhat sketchy for Mannheim standards: The ball placement wasn’t quite pretty, then they disturbed the opponent a bit, couldn’t shoot the ball accurately, and finally even kicked the ball out of the field. This earned Mannheim a yellow card, meaning they will play with one less robot for the next 2 minutes.
02:49 A strong back-and-forth on the field: Sometimes the ball is in TIGERs’ half, sometimes in Immortals’. But eventually, it ends up with Immortals – in their goal!
Immortals 0 : 3 TIGERs Mannheim
02:26 After some sluggish corners that Immortals unfortunately couldn’t place, it’s back to the attack for TIGERs. But Immortals can clear at the last second by deflecting the ball out of bounds.
02:20 A little outburst from the Immortals robots: Some of them spin quite quickly in circles, making the Immortals members a bit uneasy, but the problem seems to fix itself.
02:17 And now it’s time again: Eventually, the TIGERs robot manages to get past the Immortals’ defense and shoot the ball into the goal.
Immortals 0 : 4 TIGERs Mannheim
02:06 And immediately another successful shot on goal by TIGERs Mannheim. They increase their lead to 5.
Immortals 0 : 5 TIGERs Mannheim
02:05 The first substitution of the game: An Immortals robot has to come off.
01:55 Another shot on goal by TIGERs, but this time the ball is too high, so the goal doesn’t count.
01:15 And another goal by TIGERs Mannheim. The AI referee reports again that the ball is too high, but we doubt that. And indeed, the human referee decides: Goal by Mannheim!
Immortals 0 : 6 TIGERs Mannheim
00:28 Again a very nice and fluid game by both teams. No interruptions disturb the flow of the game. The Immortals bots fight against the goal threat for a long time, but eventually, it’s time for another goal by Mannheim.
Immortals 0 : 7 TIGERs Mannheim
-00:05 And of course, TIGERs often finish the first half with another shot on goal, so we go into halftime with a score of 8:0.
Immortals 0 : 8 TIGERs Mannheim

Second Half

05:00 And so the second half begins. The teams have switched sides, which is actually rather unusual in modern SSL games.
04:30 Still a fairly quiet game in the second half so far. Eventually, TIGERs start an attack, but Immortals simply shoot the ball out of the field.
04:13 Again, strong pressing by TIGERs Mannheim, but the ball just misses the goal.
03:55 And the pressing continues, but this time it doesn’t end well for Immortals: The ninth goal for Mannheim!
Immortals 0 : 9 TIGERs Mannheim
03:18 Although the ball lands in Immortals’ goal, it was obviously a chip shot. Therefore, the goal doesn’t count.
03:08 Indeed, a rare moment where TIGERs have to substitute a robot.
02:50 Strong defense by Immortals, but the pressure on them is still immense. Let’s see how long they can withstand the pressure.
02:40 Well, it didn’t last long. After a nice attack, it’s ironically the Immortals goalkeeper who deflects the ball into the goal. Thus, the game ends early at 10:0, and TIGERs Mannheim can now officially call themselves the German SSL champions!
Immortals 0 : 10 TIGERs Mannheim

German Open: Friendly: ER-Force vs. TIGERs Mannheim

Posted on by

Although we weren’t supposed to have another game today since Tritons unfortunately can’t compete in the small final (they aren’t even in the hall anymore), we are playing a friendly match against TIGERs Mannheim.

As always, the game can be watched on the livestream from TIGERs Mannheim:

This game has a special feature: TIGERs will always play with the same number of robots as we have on the field. This has already led them to take one robot off the field before the game started.

First Half

05:00 The game begins: ER-Force is playing in yellow, TIGERs in blue.
04:06 With a few outbursts, we are actually playing quite well and even have a few shots on goal now and then.
04:06 At some point, there was probably a goal, but none of us noticed. We trust TIGERs on this one, so: Goal for TIGERs.
ER-Force 0 : 1 TIGERs Mannheim
03:36 After heated duels in our half, our robot seems to lose interest and kicks the ball mercilessly out of the field.
03:21 The duels continue in our half. Eventually, TIGERs manage to score.
ER-Force 0 : 2 TIGERs Mannheim
03:02 Still some nice scenes from our robots and occasionally a shot on goal. Definitely a much better performance than the last two days.
02:01 Again, some nice game situations for both sides. Overall, the game is quite fluid, and there are some nice long passes from both teams across the field. A very lively and balanced game.
00:34 The stream of this game is really recommended. We no longer give Mannheim any gaps or breaks; our goal is currently secure.
-00:29 The last minute has been dangerously long in our half, and there have been some scary moments. But the first half ends without another goal, our defense still holds.

Second Half

05:00 And the second half begins.
04:28 Again, the ball is in our half for a long time, and our goalkeeper is intensely arguing with one of our field players. Moreover, he simply doesn’t kick the ball away. And so it happens: Goal for Mannheim!
ER-Force 0 : 3 TIGERs Mannheim
04:02 OK, that was unfortunate: For some reason, our communication didn’t work, maybe someone bumped into it. As a result, our robots just stood still, and TIGERs could shoot into the undefended goal.
ER-Force 0 : 4 TIGERs Mannheim
02:50 Now the game is playing a bit more in the Mannheim half. Let’s see if we can score a goal against the world champion.
01:24 An extremely long game in midfield and the TIGERs’ half. Our robots keep trying for the goal, but they just can’t get past the defense and the goalkeeper.
00:59 That was close! A short duel near our goal, then the shot, but just missed! The score remains unchanged.
00:52 But now, unfortunately, it happened: Still dueling in our half, but our robots sometimes just don’t shoot. Probably the light barrier doesn’t recognize the ball. Be that as it may: Goal for TIGERs.
ER-Force 0 : 5 TIGERs Mannheim
00:34 And timeout for us: The AI is set to aggressive.
00:09 That’s the disadvantage of Main Aggressive: When the ball comes into our half, there are no defenders left. And so another goal is scored against us. But what the heck: It was still worth it.
ER-Force 0 : 6 TIGERs Mannheim
00:00 And so the game unfortunately ends goalless for us. But still, it was a very nice culmination for the tournament: Eight of our robots were on the field and could play for an entire half. Even our Victory Move was not prepared for that; it apparently can’t handle so many robots. So we let TIGERs have their Victory Moves. For now.
