A lot of well-meaning parents really, really want their child to learn a second language. However, it's hard to teach a language when you don't actually speak it yourself. Flash cards, videos and apps are all great, but real retention only happens through regular social interaction. Enter Flash Robotics' EMYS, a Kickstarter project that isn't just another mechanical assistant -- it's a friend that chats, plays and makes sure your kid walks away with some knowledge of the Spanish language. The dome-headed robot is named for how its head resembles certain species of turtles, but its segmented skull is probably more akin to the stacked lines of an old AT&T logo.

We report a study performed with a social robot that autonomously plays a competitive game. By relying on an emotional agent architecture (using an appraisal mechanism) the robot was built with the capabilities of emotional appraisal and thus was able to express and share its emotions verbally throughout the game. Contrary to what was expected, emotional sharing in this context seemed to damage the social interaction with the users.
