Distinctly Different Dynamical Processes in Maintaining the Intraseasonal NAO+ and NAO−

Dynamical Feedbacks and the Persistence of the NAO

The persistence of the North Atlantic Oscillation (NAO) is studied using observations of the threedimensional vorticity budget in the Atlantic sector. Analysis of the relative vorticity tendency equation shows that convergence of eddy vorticity flux in the upper troposphere counteracts the effect of anomalous largescale divergence at the upper level. At low levels, the convergence associated wi...

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...
