The sinister looking snakebot to the left may just save your life one day. World, meet Cardio Arm, a "kinder, gentler way to tinker with your ticker":
... a foot-long serpentine robot designed to assist in cardiac surgery. The device worms its way into a patient’s chest through a three-quarter-inch incision in the solar plexus. A surgeon controls movement of the robot’s head with a joystick, and the rest of its 102 joints snake along behind. A tiny, front-mounted camera lets the operator see where the Cardio Arm is going and make course corrections.
