Post-RoboCup 2007 Diary: Day Two

Day 2. The Second Day. RoboCup World Championships 2007. Here we go.

This day was by far one of the most infuriating days in RoboCup history. It all came down to the lighting. First off, we only had three fields. Three fields for 24 teams. Last year in Germany they had four fields, and none of them were practice fields. They were all game fields. Secondly, the lighting, even by the morning of the second day of set-up, was horrid. The lighting inside the Fox was really dim to begin with — I myself had deluded visions of ghosts past in the team room — and the beams on the fields were not enough. Joho was up there on those ladders with his flip-flops in hand finding lighting solutions with Naomi, the spunky NUbot vision guru. We all got to the venue @ 7 am to meet with lighting guys who were supposed to show up.

The morning was kind of a blur, as of course the lighting guys didn’t show up right away. The lighting guys came, and after much appeals from myself and Chown-Dawg, a real boss came and was not happy with the progress. He sent out for more lights, the best solution we could think of, and when they came back, things started to click in. The new lights were, according to Joho, what we needed.

MORNING:

Day One is game-face day. One needs to make entrance to international robotic dog soccer competitions. Tucker, Jesse and I decide to take care of registration. Jesse asks me: “Are you sure you have the registration materials?” “I’ve got it covered. No problem.” So we stroll.

Suddenly, as we stroll through midtown Atlanta, I’m hungry as all get-up. So where do we go? That’s right, American’s Kitchen: CVS Pharmacy. A few granola bars later, I’m straight. So after some guessing, we think that our best bet to get to Georgia Tech campus is to catch a bus 12 blocks away. We get there. Man, is it hot, we think. We wait around wondering if we’ve reached the right place. Finally, we see a special ‘Stinger Bus’ fitted with a ‘ROBOCUP’ sign. I grimaced as it isn’t properly punctuated as ‘RoboCup’. Never the less, despite their sheer insolence, we board. On the bus… RoboCup people from foreign lands! Sweet!

Post-RoboCup 2007 Diary: Day Zero

Day One
Day Two
Day Three

As in Computer Science, this journal starts with Day Zero. I’m flying at thirty thousand feet with the nBites crew, and the outdoor elements are making bad metaphors outside of the plane. On the starboard side (does boat terminology work on airplanes?) , there is a perfect ROYGBIV sunset. On the left hand side, a raging lightning storm of death. Remarkably, this plane is flying straight through the middle. I can only figure that this can only be a sign of the journey to come. Either we fade gloriously into the sunset, or a lightning bolt fries our ass. Atlanta, here we come.

–Weeks Later–

Well, it turns out that neither greatness nor failure can happen sometimes. We got diverted. As ball-lightning descended upon the ginormous Hartsfield International Airport, we went elsewhere. We landed with other planes @ an airport without jetways. We hung out there, posturing as we considered bringing our robots out of their shells and let them stretch their legs on the floor. We took off again, and made it to Atlanta. We were blearly-eyed as we ran into a group of blind people getting on the terminal subway. We were worried when one decided to go left exiting instead of right.

Northern Bites Finishes Third at the German Open 2007

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!

First ever Northern Bites doubled digit score at competition!!!!11ONE

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.

Goalies Should Stop Goals

The Northern Bites pool play at the German Open got off to a disapointing start. In the first game of pool play for pool B we were defeated 8 – 0 by the German Team. Although the goal differential was quite high, play, particularly in the second half, was even at many times. The German team’s largest advantage came from the goalkeepers on the field. Our goalie was having a difficult time localizing and was positioning poorly in the goal; in opposition, the German Team goalie played very well and blocked multiple Northern Bites shots. Our second game will be this afternoon and we hope for a much better result.
