Magdeburg day 2

This morning we stormed punctually the exhibition hall and engrossed a table directly at the field and corridor. Prompt we set up our laptops and monitors and covered our ambience with a meshwork of electric, network and monitor cable. Meanwhile the Word-Wide-Web is also available to us more or less regularly, thanks to a fast placed wire straight through the hall.

Also intranet with an own git-server and documentation, as well as a connection to the robots were quickly set up, to prevent usually very unstable global network.

When the day draws to a close, we slowly engross the whole rest of our table, after it was clear, that no other team needs the space. Our working conditions are as good as they could be in an exhibition hall.

Just now (1 am) the last one finishing their programming work and even the homepage article is as good as done.
Tomorrow we will get up at 7 am and prepare for the competition.

Back from Mexico

The Bit-Bots landed more or less safely at the Hamburg Airport yesterday evening. The Team looks back at a successful world cup, with a lot of knowledge sharing with other teams and some smaller, hard earned, successes (our robot actually threw the ball!).

An official ranking which takes into account the technical challenges unfortunately has not been published yet. Because we made 8 Points there, and only six teams dared to approach the challenges, we hope for a place in the top-ten despite our defeats. Currently only the results of the individual games can be viewed online.

While the team members that attended the world cup still recuperate from their jet-lag we have prepared some visualisation of the work on our software within the last weeks.

The nodes of this tree-structure represent files and folders in the main development branch of our version control system.
One day reflects to roughly 10 seconds of the visualisation and you can see how developers modify the project with each commit (green = add, orange = modify, red = delete). At June the 15. was the take-of for the team. You can clearly see how the competition had impact on our activity. (The Time reflects to CEST, the local Mexican time is -7 hours)

For the technical interested: We use gource as a visualisation tool for git. Linux-Users can install it directly via their software-center.
If you change to a directory containing a git-repository and execute “gource”, it will render a nice visualisation of your own project.
Pretty much of a show for just 10 seconds of work!

Mexiko: Day 6

We had our first match against the NUBots from Australia this morning. We were evenly matched, but on field our robots had some troubles, like game-ball recognition, since the game field was very dark and the general lighting conditions weren’t that good either. Furthermore we had to struggle with an unstable WLAN connection with the gamecontroller. Nevertheless we managed to maintain a score of 0:0.

The second match was only an hour later and Maike was chosen for the referee of another game also. This was unfortunate, since we couldn’t improve much meanwhile. At the beginning of the match against Team RoBIU from Israel, Maike wasn’t finished with her job. Furthermore our game was at another game-field again. This resulted in another problem: we had to correct the game-ball recognition again. With the help of a timeout and the half-time break we managed to fix it, so that we were able to play correctly in the second half. This is visualized in the score: In our first half our opponents scored 4 goals, but in the second half only one. So the game end with a score of 0:5.

After that we focused on the upcoming last match against the world cup holders DARwin and the throw-in-challenge, coming up tomorrow noon.
And so a stressful day is drawing to an end.

Here are some pictures for you:

Mexiko: Day 5

As mentioned before, we had our first match against the Berlin United – FUmanoids ending with a score of 0:0 this at noon. Since there was no winning-team, we had a penalty shootout in the evening to decide this match. So we had all the afternoon to improve the behaviour of our goal scorer and fix some bugs, that occured during the game.
The penalty shootout was very nerve-wracking for both teams and the spectators from the other teams. The first 5 attempts to score a goal weren’t successfully for any team, so the rules dictate that the following attempts were made without a goalkeeper. After 11 additionals attempts and half an hour later, the Berlin-team was lucky and scored a goal. In our team nearly everything failed and we lost with a score of 0:1.

At the end of the day, we celebrated Maikes birthday (in accordance to the German time) with a nice ‘Happy Birthday’ and a cake.

Wilma in action!

Mexico: Day 4

We were busy working the whole day until 11 o’clock pm on programming and testing.
Now our players have a stable walk and the goalkeeper gets (nearly) every ball. For tomorrow (wednesday) it is planned to implement the elaborated behaviour for the outfield players.

Anything else? Oh, yes, we got a cool referee t-shirt.
