RedEaredSlider writes "The first ball at the Phillies-Brewers game will get thrown by a robot — but Roy Halladay's job is still safe. As part of an outreach program and the Phillies' 'Science Day At The Ballpark,' the University of Pennsylvania's School of Engineering and Applied Science is showcasing a robot made from a Segway and featuring an arm that acts more like a human throwing than an ordinary pitching machine. A pitching machine functions more like a gun, firing a baseball in what amounts to a straight line. But the robot has an armature connected to a hand that was specifically designed for throwing. Another thing the robot can do is identify the strike zone."
