Motor problem found!

After several weeks we finally found the bug that misaligned our motors:

It seems that the motors don’t like the power supply to be disconected shortly after setting new values….

Tamara was the one to suffer for automatic tests:

Finally we can start working properly!

Hamburg Bit-Bots on German Protestant Kirchentag

From 11am to 1pm we had nine robots within the ESA East building today to astonish young and old. Next to our five DARwIn-OP robots, which could at least show some of their abilities during penalty shooting, we also had two Sony AIBOs and two Nao robots with us.
The weather was a little bit to friendly to us, so that the the sun was shining the whole time through the glassy ceiling. With such bright light our robots haven’t had any chance to find the little orange ball on the field. Just our hero Wheatly went for the ball as always no matter what the sun was doing and scored one goal after another. The poor Glados who was the goal keeper in this moment was totally confused, although he showed some brillant actions to keep the ball out of the goal some time.
Even without the announced test game against our own robots, there where a lot of questions which where answered via the microphone from different members of the team.

This day brought a lot of fun and the feedback of the audiance showed that we weren’t the only one who had a lot of fun. We hope that we can show you some pictures in the next days. Thanks a lot to Jessica, who was present this day just to make some of those pictures.

GermanOpen Day 5: Double-crossing FUmanoids

We had our game against FUmanoids from Berlin this morning and played with the successful software from the previous game with just a few improvments like running to the ball and not straight around it.
Our robots had many undesired ground contacts during the first half, but the action took place in midfield or on the opponent’s half most of the time. In half-time brake we did some successful adjustments to our walking. Anyway, action shifted to our own half of the field.  Even so, no goal was scored. On the one hand this was owed to the fact that the robots from Berlin were gracious to us and on the other hand GLaDOS excellently saved his own goal!

In the end we had two second placed teams in our round robin group, because the Bold Hearts surprised with a 1-0 victory against the WF Wolves. If the game had ended 0:0 it would have been necessary to make a penalty shoot-out against all opponent teams against an empty goal. The team that would have needed the least time until the goal was scored would be first in group and so on.  Fortunately Bold Hearts spared all teams that.

So we met FUmanoids in the semifinals for the second time and semifinals are not supposed to be finished with draw. Both teams did their best to avoid a penalty shoot-out in the end. The game was balanced and exciting. Robots from FUmanoids as well as our own robots had good chances to score into both the opponent and the own goal. After 20 minutes of game time it went into extension. It went on the similar way with the only change that half time is shortend to five minutes and so there were at least even less shots on a goal. Berlin had a really great chance in the final minutes of the 2nd extension, but again GLaDOS made it! He jumped in the right moment when the ball threatend to pass the goal line and even prevented the attacker from progressing to the ball after that.
So it came to the penalty shoot-out. There’s not much to say, it is best to look at the video.
