Northern Bites: 8 Cerebus: 3
Wasn’t by far our best game, but wasn’t bad either. We got some good goals and were aided by a sometimes crashing opponent goalie. And our goalie looked pretty solid the whole game too, making two big saves, but missing a few hard shots from outside the box. We’re really amped to get back in the lab and start making things better for Atlanta. Our color table looked crappy in the second half — we weren’t grabbing at all.
As Tucker just said, he liked how the GermanTeam came over and said ’so you fixed your goalie?’. That’s sweet.
Roll, nBites!
We’ll let you know how it goes. Our robots played well in a test match against the GermanTeam, but as usual I’m wrecked with nerves.
The semi-final went great. We now have officially documented proof of our goals against the NUBots. The final score was 10 to 3 NUBots, but the scores by half were 7 to 1 in the first and 3 to 2 in the second. At half-time we moved back our defender position and tried to make the goalie be a little more aggressive. That being said, the NUBots were seeing balls in our red player uniforms and were thus not playing as well. We are very confident that we will win the 3 – 4 game tomorrow.
The most exciting thing about this game is that we now have a keeper who stays in goal. Henry debugged the post distances which were being reported incorrectly and it had profound effects on the localization of the goalie. It also helped that we were using C3PO, an M3, because of Leo’s breakdown, the switch to 3PO helped definitely with positioning, but his vision and behaviors were not as fully tested on the ball and thus, although he blocked some balls he never attempted to clear them, something which made it very difficult to stop goals.
All in all we are looking loads better then our 8 to 0 loss to the German Team on opening day of the tourney.
Tonight we are packing up early and celebrating with a real dinner. Tomorrow we play Cerberus, a team we beat in the prelims and now with are improved code we hope to make our margin of victory much larger than the one we had in pool play.
We still have lots to work on, but being one of only three teams with a positive goal differential is a good feeling.
Northern Bites: 12 Harzer Rollers: 2
Changes from last night’s game included an updated color table, some behavioral improvements to ball chasing, and the removal of a significant bug that had been lingering in the vision system for over a year. With the vision bug corrected, localization for all players was improved and the keeper was staying closer to the center of the goal. Unfortunately he was still having problems and let in one goal after trying to clear it and then not finding the ball sitting next to him.
We entered half time with a lead of 4 to 1. After a couple goals by us in the second half, our goalie began to have troubles moving his leg and could not position himself back in the goal. At this point the Rollers had a strong head kick and a goal was scored. We called a time out to asses the problem, but could not use any of our back up robots, since we have not been able to get any of our M3 Aibo’s to work with the competition wireless LAN.
We replaced the keeper’s stick so that he would stand in goal and do nothing. This defense was effective in that our offense began to dominate, proving the old adage true that the best defense is an intimidating figure standing still and doing nothing. Maybe it’s a good offense. Even though we had a few problems with wireless lag the robots began shooting on goal with much more authority.
We play the NuBots in the semis at 6:00. We played three halves against them last night being scored on at least eight times (Henry says eleven) and scoring two goals (one while the NuBots had taken a player of the field). At this point we don’t have any proof of the goal against the NuBots, but we will on the video after tonight’s game when we beat them soundly.
We’ll post again after the semi’s.
We had a great end to round robin play. After an afternoon of debugging, variable tweaking, and constant testing, we polished our team to play at their highest level of play at the tournament.
We had improved grabbing and roll switching from the earlier game today and although the goalie was still having problems localizing, he was looking better. With the win we secured the second place seed for bracket B and we will be playing in the quarterfinals tomorrow at 2:00 against Harzer Roller.
Tomorrow should be exciting and we have high hopes of moving on from the quarters to play the NUBots in the semifinals. A scoreboard of all the games can be found here.
