Gearing up for this week's CEATEC trade show in Tokyo, Toyota on Monday announced that its compact-sized Kirobo Mini, pitched as a "communication partner," will go on sale early next year in Japan. The Mini is a smaller version of the astronaut robot Kirobo, which visited the International Space Station in 2013. The Kirobo Mini is meant to take part in more down-to-earth affairs -- such as routine driving trips. It's about 4 inches in height, and it can communicate via expressions and gestures.
