Relationships between Optimal Precursors Triggering NAO Onset and Optimally Growing Initial Errors during NAO Prediction

NAO-mark vs QR-code Recognition by NAO Robot Vision

Nowadays, the research on robot on-map localization while using landmarks is more intensively dealing with visual code recognition. One of the most popular landmarks of this type is the QR-code. This paper is devoted to the experimental evaluation of vision-based on-map localization procedures that apply QR-codes or NAO marks, as implemented in service robot control systems. In particular, the ...

Contrasting interannual and multidecadal NAO

Nao Devils Dortmund Team

The Nao Devils Dortmund have their roots in the teams Microsoft Hellhounds (and therefore part of the German Team), DoH!Bots and BreDoBrothers. The team had a number of successes, such as winning the RoboCup World Championship twice with the GermanTeam (2004 and 2005), winning the RoboCup German Open 2005, the Dutch Open and US Open 2006 with the Microsoft Hellhounds, and winning the Four-Legge...

Football detection on Aldebaran Nao

RoboCup is a worldwide movement that has a clear goal set: the target is to be able to win a FIFA World Cup winner by 2050. In order to be able to fulfill the task, the RoboCup Humanoid Soccer World Cup is organized every year. The organizers make the task of playing football more difficult year-by-year. During the last few years, the goals changed from blue and yellow to white. Considering tha...

Contrasting interannual and multidecadal NAO variability

NAO variability on the two timescales is associated with different dynamical behaviour in terms of eddy-mean flow interaction, Rossby wave breaking and blocking. The two timescales also exhibit different regional impacts on temperature and precipitation and different relationships to sea surface temperatures. These results are derived from linear regression analysis of the Twentieth Century and...
