Good Press Coverage (updated)

fh just sent me a link to an article on the ORF webpage that shows several pictures of our team. Carpe Noctem team members (or equipment) is shown on pictures number 1, 12, 20, and 21. The question is now: is this cute little sandwich toaster in picture number 20 a team member or equipment?

Update 2009-06-30 21:41: Just found some more digital foot­prints of Carpe Noctem in the web, added as realted resources.

A Factor of 10

Carpe Noctem achieved a quite good result in the Technical Challenge (arbitrary ball detection). They managed to find two of three balls but weren’t able to kick them (still because of some issues with the ball approach­ing behaviour, I suppose). Therefore, they got 2 out of 6 points. Great, guys! :)

Mostly Harmless got even 3 out of 6 points, great done, Minihops! (see heise.de)

Then to something com­pletely different: It seems that copying the system design in RoboCup is still a highly appre­ci­ated devel­op­ment technique. Reportedly the layout of several robotic platforms from the past years exper­i­enced a revival (the Tribots and Tech United platforms, for example). Moreover, thanks to the live stream of Tech United, I saw some team t‑shirts the design of which is very close to ours… well, good to know that at least our t‑shirts leave a mark ;)

Regarding the title of this post … well, ask Kobotroll or Endy :)

RC2009: The Second Day

For Carpe Noctem, the second day of the RoboCup World Cham­pi­on­ships 2009 began with an explosion. A short-circuit in our booster device (a step-up converter for our kicker) caused a high current voltage path to instantly evaporate while emitting a big bang. t2000 and elm reported that after the explosion there was complete silence in the hall. This may be an appro­pri­ate measure for keeping children, teachers, eco­nom­ists, and other highly chatty people calm, no? Well, we will probably elaborate on this topic later on. Appar­ently the reason was a broken cable that caused the short-circuit.

elm sent me some pictures that quite nicely show the problem as well as the result.

RC2009: The First Day

RoboCup 2009
RoboCup 2009

It’s Monday, the first day of the RoboCup World Cham­pi­on­ships 2009. First days are known to be exciting in several ways: You arrive at the venue, look around to find out what is there you didn’t expect, you get excited or start bringing yourself back down to earth, meet old friends, try to get settled a bit, and start going crazy. The latter most likely happens not later than two days after a tour­na­ment has started. This year, they managed to tick all these items off in only one day. But let’s start from the beginning.

Today, the teams had to realise that using elec­tron­ic compass modules is not possible in the hall, simply because of high current power lines running below the play­ground. After restruc­tur­ing (and exchan­ging) some loc­al­isa­tion stuff, Carpe Noctem seemingly managed to get things running again. The next issue was that the ball con­stantly got stuck in the ball handling device, which means that the robot was unable to dribble or even to move anymore. I know nothing about the current state of this issue but I feel confident that they get this issue ticked off as well.

Last but not least: The Rules. Every tour­na­ment’s darling. To be more precise I’m talking about the people or teams that insist on entire com­pli­ance with form­al­it­ies, with every damn small piece therein. I don’t want to dis­crim­in­ate against anybody. The history of RoboCup tour­na­ments nev­er­the­less documents quite well that some teams show an amazing tendency to adhere entirely to the rules, starting dis­cus­sions because of simply nothing. This time, the size of the robots was (once more) the bone of con­ten­tion. As a result, several teams now have to modify their robot’s hardware platforms. Some only need to cut some screws such as 1. RFC Stuttgart or Mostly Harmless, for example, some are asked to carry out more radical changes. This is, for example, the case for Carpe Noctem. Our old robots did not change dra­mat­ic­ally much during the last two years. Changing the mech­an­ic­al design of a robot, of a robot that is accepted by at least ten other teams, in a single night is simply impossible. So the only thing we can do now is to hope for a more realistic judgment of the technical committee. I’d not change a single screw, to be honest.

That’s it for now. Maybe there is some better news tomorrow. Ah right, tomorrow is the technical challenge, at least according to Don Miguel de Homer’s blog. I still keep my fingers crossed! :)

RoboCup 2009 in Graz About to Start

Graz in Austria is the scene of this year’s RoboCup World Cham­pi­on­ships. My former team Carpe Noctem arrived yesterday and, as far as I know, suc­cess­fully moved into their new home for the next week. Via Jabber, elm keeps me informed about the progress and the more important news. The current state is that the team is busy with setting the robots and doing some initial testing and tuning.

So at the moment, everything seems to go quite smooth, the first robot is up an running, and is even able to dribble a ball. For me it’s actually quite hard to sit that far away (1200 km 820 km air-line distance) in front of a more or less tiny screen, not being able to do or help anything. But anyway, my flight departs Friday morning! I’m really looking forward to the end of this week :)

For now, I’ll post some pictures elm sent me. This is how it looks like in the venue in Graz:

GO 2009 Review by SEW-EURODRIVE

During the Hannover Messe I gave an interview to somebody I actually don’t remember anymore. Some guys from the organ­isa­tion or the sponsors or whatever, whoever. Yesterday then Hendrik came across a video on YouTube where a short part of this interview is shown. Horrible to see myself talking… :)
