Smart Mars rovers to think, work as team CNN

NASA is working on a new breed of rovers whose sole purpose is to work together on Mars. They are robots that basically act like synchronized swimmers for construction work. The space agency envisions a martian building crew consisting of multiple rovers. Prototypes can now lift and move an eight-foot metal beam. While it may not seem like much, it actually represents a major accomplishment in robotics. They use experimental software that allows them essentially to share a brain.
