Who will the courts blame when the first driverless car kills someone? That's "when", not "if", as deaths from driverless cars are a near certainty, and the logic behind who the car decides to kill is a good introduction to the fascinating and terrifying world of our coming robot future.

Fortunately, we need not go blindly into this future. Robot Law is volume of research on robotics law and policy edited by Ryan Calo, A. Michael Froomkin, and Ian Kerr. Calo is a professor at the University of Washington School of Law, who frequently writes about where the laws of man and the laws of robotics intersect. So what better way to illustrate the book's cover than a cartoonish, Rock 'Em Sock 'Em robot game turned into full bar-side brawl? Thanks to art by Eric Joyner, we get this delightful spectacle of mechanical mayhem.
