The sole purpose of this robot is to make you bleed

Remember the old saying, "don't bite the hand that feeds you?" Well, this robot is choosing to prick the fingers that build it. "The First Law," as the robot is nicknamed, is a simple machine made up of sensors, a metal arm, and replaceable diabetes needles. A random algorithm programmed into the robot decides whether or not to deliver a sharp prick to your finger. The bot's creator, artist and roboticist, Alexander Reben, is not a masochist.
