In 2012 the German Unity Day has been celebrated in Munich. The celebrations include a showcase of the German federated states (Bundesländer) and also other institutions like the parties of the Bavarian parliament. Also research facilities and the industry have exhibitions. In this case the DLR presented its humanoid robot "Rollin' Justin". See a video of it catching balls on YouTube.
Munich is the capital of the German state of Bavaria and is Germany's third largest city, located on the River Isar north of the Bavarian Alps. Black and gold - the colors of the Holy Roman Empire - have been the city's official colors since the time of Louis IV, Holy Roman Emperor.
