Frog and Robot sculpture in Sendai, Miyagi Prefecture, Japan. Appears to be created by Tom Otterness.
One thing that struck me about IREX 2011, and many robot exhibitions shows here in Japan, was that children and students were an active part of the whole experience. While technology exhibitions I have attended overseas tend to exclude anyone under the age of 18, shows like IREX encourage their participation. There were lots of activities for the young, budding robot enthusiasts, and the sales staff even at major factory automation booths welcomed and mentored them, patiently explaining how the robots work and how they benefit the company's customers and society in general.
