Unsuspecting office workers beware. You may already be in the cross-hairs of a ping-pong ball launching robot. This covert robot hangs out on the other side of a suspended ceiling, waiting for its operator to unleash the fury. When put into action a hatch in a ceiling tile is raised and balls are launched at a cowering cube-dweller.
It looks like the balls are launched at a reasonable speed and won’t hurt anyone. The next generation of this bot should do a better job of integrating the trap door and be quieter. This would be a lot more fun if the victim couldn’t figure out where the heck that ball just came from.
