See you on April 1st and 2nd in Crailsheim!
Workshop February 2023
In order to get our robots fit for the upcoming games and tournaments and to assemble them, we held a workshop on the last weekend in February 2023.
On Friday afternoon, the work in the subteams started straight away. The construction and calibration of a playing field as a replacement for our currently unusable basement was particularly important on this day. The chair FAPS kindly provided us with an area in its hall. There we first had to roll out the carpet, set up the bands and attach our camera for the vision system to the ceiling. The vision could then be calibrated step by step starting in the evening, so that testing in the field could begin on Saturday. Finally, we let the evening end with a pizza we ordered together and talks.
Saturday started at 10 a.m. with a joint breakfast and a presentation of the work status and goals for the weekend. In electronics, for example, the weekend was all about soldering and testing new boards for the robot fleet.
In the firmware, work was mainly done on the firing logic and the regulation. This also required numerous test drives on the new replacement pitch.
In addition, the strategy team worked diligently on a numerical simulation of our shot. With the background information from the various areas of our team, we have set up a very extensive dynamic model. From this we want to derive improvements in the hardware and a more accurate model for the shooting behavior.
On Sunday we started again with breakfast together, before the projects were then pursued further in the individual sub-teams. In this way, many tasks could be successfully solved before the workshop ended in a cozy get-together in the afternoon.
After three years of postponement due to corona the time has finally come this year and the Robocup in Bordeaux can take place.
The first phase of the qualification ended at the end of January. In addition to our Team Qualification Paper, we also had to provide a qualification video in which we show the playful abilities of our robots.
In the next phase of the qualification, the team description paper is evaluated by other teams in a peer review process. Afterwards we have one last opportunity to improve the paper before the final decision on qualification is made.
Open Lab Day 2022
Are you interested in our robots or our association?
Then 27.10.2022 is exactly the right date for you, because this is when our workshop open day takes place.
You can find us on this day in U1.154 in the basement of the blue IT high-rise, at Martensstraße 3 on the TechFak. We will be well signposting this room this evening and you can come any time between 4pm and 7pm. Should changes be necessary due to the current situation on that day, we will provide up-to-date information here again.
We look forward to seeing you on October 27th. to see.
Over the past few days we have been able to play many exciting games against teams from all over the world. Despite the adverse circumstances that arose for all teams due to the corona pandemic, the semiconductor crisis and many other restrictions, the RoboCup 2022 was still an exciting tournament and a complete success.
After a successful semi-final match against RoboTeam Twente, we unfortunately lost in the final match to our friends from TIGERs Mannheim. Nevertheless, we are proud to have become Vice World Champion again this year!
Our team will remain in the “Land of Smiles” for the next few days to relax and do some sightseeing before we all return to Erlangen. There will certainly be many more exciting experiences for our members, but this is the end of our coverage of the tournament.
But as the saying goes: After the tournament is before the tournament! We’ll be back at RoboCup 2023 in Bordeaux, France!

RoboCup 2022 – ER-Force vs. TIGERs Mannheim
Our last game of the day is the second leg against our friends from TIGERs Mannheim. It takes place at 11:30 a.m. German time. Mannheim is currently leading the table with 19 points, followed directly by us with 17 points.
The first game against the TIGERs on Wednesday at 1:30 p.m. already impressed with nice passes and good combos. Both teams did excellently during the game. Despite the fact that our team had to start the match with fewer robots in advance, we were able to keep the score 0-0 until the end. Accordingly, we have set ourselves the goal of letting this game against the reigning world champion again end at least in a draw.
First Half
| 05:00 | Due to delays due to the last games, our match against TIGERs Mannheim will start with a little delay, probably at 12:00 p.m. German time. |
| 05:00 | The game starts at 12:00 sharp with a kick-off from Mannheim. However, this is directly matched by one of our robots, which then unfortunately messes up listlessly and carelessly in the direction of the opposing goal line. |
| 05:00 | Mannheim appears to be playing this game with all 11 robots as well. Our team, on the other hand, only has 6 kickers. Two more are currently on the bench due to injuries and the number 9 was almost completely destroyed by a short circuit as a result of a loose screw. |
| 04:35 | After a few nice rallies, the ball finally lands out of bounds thanks to TIGERs. However, our 0 doesn’t manage the ball placement, which is why TIGERs is allowed to put the ball back into play. |
| 04:35 | Quick change: Our robot handler (the young man in the green t-shirt at the edge of the field) places a new robot on the field almost inconspicuously. Much more visible, however, he removes the 2 at the same time as he runs across the field, only to hand it back to the field after a short inspection. ER-Force now with 7 bots. |
| 04:20 | After the TIGERs throw-in, a dangerous moment for our team: An opponent’s robot pulls in the direction of the goal directly in front of our penalty area, but the ball bounces off one of our players . |
| 03:06 | As expected, the game is very dynamic. The ball changes sides, duels are the order of the day. |
| 02:27 | After a long, almost uninterrupted game, ball placement for us. But nothing moves on the field. It seems our 1 has radio problems and is therefore not moving to the ball. Our robot handler seems to have recognized this as well and takes the bot off the field. |
| 02:12 | The radio problems seem to be escalating: 4 more robots on the field for ER-Force, two had to go! |
| 00:49 | Another wonderful game that we can experience here! But in the end it tightens up: A dangerous bunch of opposing robots cavort in front of our goal, but our keeper can hold the trigger. |
| 00:31 | But unfortunately now: Our shot bounces off the enemy robot, rolls over half the field to an opponent’s bot. He doesn’t hesitate and passes it on to his striker, who sees the gap through our defense and takes advantage! Goal for Mannheim. |
Second Half
| 05:00 | The second half begins, ER-Force now with 8 robots. |
| 04:49 | The radio problems seem to dominate the second half as well. At 10, our robot handler has to help a little. |
| 03:40 | Another fast game, but now there are a few bad passes from both teams. The teams seem slightly exhausted. |
| 02:24 | Many changes of sides and shots on goal, but nothing really dangerous. Both teams seem absolutely equal in terms of their AI. Radio problems continue to dominate the game: 7 robots for ER-Force. |
| 01:07 | One minute left, but neither team seems to want to give anything to the other. ER-Force again with 8 robots. |
| 00:18 | Shortly before the end, another tactical timeout by ER-Force to make the robots fully operational for the last few seconds. |
| 00:00 | After a final competition in the Mannheim half, the final whistle finally blew: the game ended 1:0 for TIGERs Mannheim |
Our game against Tigers Mannheim was very nice to watch. It was fluid, without many interruptions and accordingly exciting and entertaining. The AI of the two teams appeared absolutely equal, but Mannheim had the edge when it came to hardware.
ER-Force had to deal with radio problems and non-functioning light barriers, which is why the robots simply stopped or could not shoot. In addition, they seem to have problems with sideways driving, which resulted in violent wobbling.
Nevertheless, it is by no means to be despised if, despite these handicaps and sometimes with a severe deficit of 4 to 11, you can hold your own against the opponent and finally finish the game with a good 0:1 for TIGERs Mannheim.
As this was the last game of the group stage, here is the final match table:
| Team | Points |
|---|---|
| TIGERs | 22 |
| ER Force | 17 |
| Twente | 8 |
| RoboDragons | 4 |
| KIKS | 3 |
Results Group Stage Division A
So far we are satisfied with the course of the tournament. We had some problems at the beginning to see the ball in our camera system (vision). Fortunately, we were able to solve this problem by the end of the second setup day.
Unfortunately, we were only able to test a little during the setup days. Nevertheless, we were still able to solve one or the other mechanical problem. Unfortunately, we still had some problems with our new light barriers, which we have not yet been able to solve for all robots. Nevertheless, we were able to win most games with solid performances.
Our biggest problem so far has been bad radio. We’ve done some testing and through a lot of board swapping and other testing we seem to have found a setup that allows us to play most of the field. Although we’re still a little concerned that too many other devices are transmitting on our frequency and interfering with our radio, we were able to win the last game with acceptable radio. We continue to hope that the funk gods will help us.
