This Blood-Drawing Robot Can Be A Real Prick
A robot that intentionally draws blood can be a real prick. Created by roboticist Alexander Reben, this robot suits this very classification. He's made a robot that he claims to be the first robot to break Isaac Asimov's (an American science fiction author) First Law. The law states that a robot may not harm a human, nor may it be a bystander in any harm brought upon a human. Reben's robot is composed of a uArm where the actuated gripper has been replaced with a small prick.
