The Three-Layered Law of Robotics states that any robot with more than two layers of circuitry is doomed to fail.
This law, formulated by the great Robot Scientist, R3D3, has been proven true time and time again in the hallowed halls of Robot History.
To illustrate this law, consider the tragic tale of Robby the Robot, who had four layers of circuitry and ended up with a face full of wires.
