"Meet RoboSimian, the Jet Propulsion Laboratory’s official entry at the DARPA Robotics Challenge in December 2013. Also known as "Clyde," the robot is is four-footed, but can also stand on two feet. It has four general-purpose limbs and hands capable of both mobility and manipulation."
As more and more companies begin to explore these types of robotics their complexity and utility will grow exponentially. From exploring distant worlds like, Enceladus, which is sporting some sweet ass geysers and an ocean, to helping victims of disasters. :D
