Poster Contest

Hi everyone!

There is an unofficial poster contest happening in our league. The goal is to base a poster off of SPQR’s new design. Shown here:

Our entry, courtesy of Nick Edises ’13 is:

We will see how we do in that contest. Hopefully we aren’t distracted from the soccer.

NBites 0 – Nao Devils 4

We lost by 4. But we didn’t lose by 5, which means that we are moving on as the second place team in our pool. We play again at 2:20 local time tomorrow in the second round robin. Quote of the day: “I have never been so excited about losing” -EJ

NBites 1 – Bembelbots 0

We scored! And we won! Had the exact same situation as our near goal in the last game. But we scored this time! We had one player, plus the goalie the whole game to avoid any WiFi issues. There was also lots of kicking the ball out the endline so it gets placed back at midfield, dribbling it down the sideline, and kicking out the endline again. So we are going to try to close that loop and hopefully actually score more goals.

Next game at 6:00pm local time, 12:00 pm EDT and 9:00 am PDT. We play the Nao Devils from Dortmund who finished in the Quarter Finals last year. Should be a good game.

NBites 0 – Austrian Kangaroos 0

Our first game was a nil-nil tie. The first half was dominated by 10 second lags over the WiFi so teamwork pretty much fell apart.

As a result, for the second half we played with one field player and a goalie. We did much better, and got the ball down on the opponent goal line, but kicked it to the side out of the goal area because another robot spun us to the side.

Our next game is at 2:40 pm local time, 8:40 am EDT.

Live Stream

Here’s a link to the live stream. They hop around to lots of different fields so it might be tough to catch us, but they might show our games too. We will try to lure the camera man over.

Scrimmage Results

We tied Penn 1-1… lots of comm failures on field D. Still not sure what caused our issues, but hope to have better results tomorrow. There were a few behavior bugs that cropped up, but it seemed to be mostly comm that was holding us back. Frustrating because there’s not much we can do to control that part.

First game tomorrow at 11:20 am local time!

Status Update

Thought we’d write a quick status update today.

Localization is looking awesome! We seem to rarely lose track of where we are, so that is awesome for making quick decisions and generally looking intelligent. This was helped by lots of vision refinements and proper identification of corners.

Comm/WiFi is working… sort of. Field D, which we are playing our first round robin pool on, is closest to the other leagues and has the worst interference. So it might be hard to start playing, but should get easier as the competition goes on.

Goalie is making progress and is getting smarter by the hour.

Our approach to the ball looks great. We are orbiting better and not walking through the ball as much anymore.

We have a scrimmage at 8:30 local time, that’s 2:30pm EDT and 11:30 PDT (Hi Mom!).

More details to come after that . Stay tuned!

2013 Bios

I know one question I get from my parents a lot is “Who is going with you to RoboCup?” I always have to answer, “People you don’t know.” In order to remedy that situation, I’ve decided to write a post providing a bio for everyone on the team this year. Hopefully, this will entertain all of you Northern Bums (that’s Northern Bites Alumni for the unelightened) as well.

Eric “Big Smooth” Chown

First!

Lizzie “Code-boss” Mamantov

Lizzie is basically a a BAMF. She got into Michigan’s Ph.D. program for Computer Science and wants to keep exploring cognitive robotics. That’s robotics from a more human than math-heavy approach for the layman. She’s getting her research started early this summer, hoping to avoid things like adjusting camera parameters (a topic in which she is the team expert) in favor of conquering new territory in areas like cognitive localization, which she has prototyped with our goalie. She might not be looking into that specific topic in her later research, but hopefully something just as exciting as watching a robot spin around in the goal while shouting “WHY ARE YOU SPINNING!!” is in her future.

Wils “New Comm” Dawson

Wils spent the majority of his junior spring and senior fall working on the team’s new wireless communication system. He might not be the first to tell you it took way too long for a product that isn’t all that great in the first place, but he will admit that he learned a lot about when to stop digging and give up. For example, he tried to fix worldview, our tool that lets us see where robots think they are on the field live. After three days he gave up, and it is now running with several bugs that have no intention of ever being fixed. At least until future generations of Northern Bites say, “What is this crap?!”. Wils is hoping that he won’t have to give up on anything else during this year’s competition.

EJ “Big Mon” Googins

Easily the team’s toughest member, EJ brings more than just his size to the team. After abandoning his once lofty dreams of a dynamic kick engine, he is the first Northern Bite in recorded history to write a localization system capable of consistently and reliably positioning our striker right in front of where the ball will be placed on kickoff. The other field players … well… more of a crap shoot, but they usually stay on their side of the field. Also the team’s expert jokester, EJ specializes in convincing certain members of the team (whom you might guess later in the post) of ridiculous stories and “facts”, which the rest of the team finds quite enjoyable to witness.

Josh “Game Controller” Zalinger

Last year, Josh was awarded the verbal honor of “Best Game Controller in the league” several times. Whether that’s because he’s good at clicking a mouse or good at being really loud and obnoxious to the assistant referees is yet to be determined. But one thing is for sure, he is the best. When he isn’t game controlling, Josh can be found working on our behavior system or charging batteries (contrary to popular belief, it is an art). Josh is also the author of our “Hack Kick Decider” which was designed to serve us in a pinch and has done its duty proudly for two years.

Ben “Bende” Mende

A combination of bending and mending, Ben patches up the vision system with the best of them. With so many holes and irregularities and messy code, what’s not to love? Nice, clean, easy to work with systems are for the weak. Though sometimes his projects get delayed, we know Ben will come around and produce a product that will eventually run fast enough to use on the robot. To be fair, his robot detection stuff worked pretty well. As our token Frenchman, Ben will be in charge of interfacing with Aldebaran. Here’s hoping he is up to the challenge! Also it’s his birthday today. Happy birthday Bende!

Josh “Gullible” Imhoff

A juggler, not just of the orange game balls, but of various systems in our code, Josh is running the gauntlet, soaking up as much knowledge as possible before the recently graduated alumni move on from the team into Northern Bumhood. Perhaps his best contribution is the new addition of dribbling to our behavior. We have yet to break it out against another team, but are looking forward to seeing how it goes. Never failing to succumb to EJ’s trickery, Josh has become one of the easiest people on the team to trick. We haven’t determined yet if it was just lack of sleep, or if his personality changed this summer, but I have a feeling we won’t find out very soon.

Daniel “I’ll Give You a Dollar” Zeller

Always trying to get teammembers to do silly stuff, Daniel takes an intelligent tack in offering the victim(s) a dollar first. But nobody paid him to make a sweet orbit or a rockin’ penalty kicker. Known for blasting Toto’s “Africa” in the lab, Dan enjoys his classic music, even entertaining Bowdoin Security at wee hours of the morning. Possessing one of the more powerful pats on the back of any teammate, Daniel knows how to give congratulations when they are in order. As an experienced traveler to exotic places such as Africa, Dan knows perfectly well which power adapters to buy for the team… oh wait… you mean it comes in European to European? Oops.

And that’s the team. Hope you all enjoyed the short synopsis! More videos and information to come!

Venue

We are here at the venue. This morning consisted of struggles to get internet, power, final lighting conditions, food and water, and some moral. Lizzie arrived with cupcakes and Ben came with water (9 half liter bottles for just a euro!) and some other snacks as well. With food in our bellies and moral lifted, we determined that the lights we not going to change in the venue any more. This is important because it lets us calibrate our robots’ cameras with confidence we won’t have to go through the process again. Everyone started taking some pictures and soon after, we had a bunch of logs to create a color table so our robots would know which colors to look for in the images their cameras take. Chown made us a “very good” color table, which is very rare on the first day. Usually we struggle to get a solid table for a few days, but this competition looks promising so far.

Internet also has worked out, pretty magically. We only had to wait 5 hours before we got ethernet at our table and we are told that the wifi access points for our robots are working, though we do not have the correct IP addresses for them quite yet. Power, on the other hand, is a bigger worry. Josh and Wils found that out the hard way, after blowing a fuse in their hotel room trying to charge our batteries. After a pop, some sparks, and smoke, they found out that our power strips are only rated to 125 volts. As you may or may not know, Europe uses 240 volts. But everything was ok. We have a transformer to convert the voltage! POP!!! … Apparently it isn’t an actual transformer… So we are using the limited number of adapters we have, most of which are not grounded, to power our computers and charge our robot’s batteries. Ben made a journey to get more adapters and returned with two more grounded ones. While Dan ventured forth to return with the wrong kind of adapters, but at least he got 6 of them.

Here are some pictures of the venue. Games do not start until Thursday, so don’t get too excited yet, but we will try to keep you entertained with some friendly scrimmages and the like.
