The hottest couple in Japan right now just may be two baseball-playing robots. Unveiled by University of Tokyo researchers in July 2009, the robotic pitcher and batter can play against each other almost perfectly. The pitcher releases a strike-zone pitch 90% of the time, but at only 24 m.p.h.; the batter hits the ball almost every time. Researchers hope to bump the pitching speed up to 93 m.p.h. and throw in some curveballs and sliders soon.
