Day 1 of the RoboCup GermanOpen has ended!

The first day of the tournament ended finding us on top of the highscore list!

The first day of the tournament has ended, and with it the bigger part of the qualification phase for the play offs. Currently we are leading the highscore list! In each game we had all our three robotinos on the field (for most of the time) and could score max points in the exploration phase.

Our agent strategy paid off when one of the robots had to be taken out and the remaining robots automatically took over it's remaining tasks. While the exploration phase was a reliable point warrant we could not get much out of the production phase. Reason for that was an unexpected effect: We had trained our color model for the vision based signal detection on single signal lights. However, in the production phase, all signals switch to green. This gave the playfield a slightly green ambience light, which our color model couldn't cope with. As a result our robots placed pucks under machines, could not detect the successful production of a good and subsequently left to try again. Nevertheless we could some points in some seldom cases where the vision managed to detect the signal change. As a result we could score at least 58 points in each game and even 74 points in our best run! This put us well on front of the others! And regarding the vision problems we have good news: We fixed it!

We will use different color models for the different phases of the game to adapt to the different light conditions on the field. Since we are already safe for the play off phase, we will use our remaining game tomorrow morning for excessive testing. In the following play offs the game will become a little bit more rough: The two teams playing on the same field will have to cross ways more often which will surely lead to lots of collisions. Since we have implemented reliable collision avoidance from on the beginning we deem ourselves to be well prepared... We'll find out :-)
