If you are thinking of being an all star slugger when you grow up, why not pester your dad to get you the Jet Hitter baseball robot? This robot was created by Japan’s Meiji University and Yokohama-based metal recycling company MRC, where it allows one to practice hitting baseballs alone, just in case you don’t have a younger sibling to boss around being the ball boy. Each time you step on a button at the robot’s base, a baseball will pop up, remaining suspended between 10cm and 20cm above a nozzle on a jet of air, where you can hit up to 70 balls (in quick succession or on your own sweet time – you’re the boss), since that is the maximum amount that the Jet Hitter can hold. According to Meiji University and MRC, several Japanese pro baseball teams have already started using the $7,700 Jet Hitter. Good luck locating all 70 balls once you are done with this!
