The 2012 International Tokyo Toy show kicked off this week in Japan's capital, with some 35,000 new toys on display for kids of all ages. Bandai's Smartpet is one of several toy robot dogs at the trade show. With an iPhone or iPod Touch for a face, it responds to voice commands and gestures with more than 100 reactions. The app lets its personality grow as it interacts with its owner.
