CNET News Daily Podcast: On building ethical military robots

Robotics engineer Ronald Arkin of Georgia Tech just finished a three-year contract with the U.S. Army designing software to create ethical robots. His thesis is that robots can be configured with a built-in "guilt system" that eventually could make them better at avoiding civilian casualties than human soldiers. CNET intern Dara Kerr talks to Arkin about his work.
