PORTLAND, Ore.—The National Aeronautics and Space Administration (NASA) with the Jet Propulsion Laboratory (JPL), managed by the California Institute of Technology (Caltech), have produced perhaps the largest variety of autonomous and non-autonomous robots the world has ever seen. Here is a slideshow of some of the most recent additions to their repertoire, including everything from a flying saucer-like craft to a selfie taken by perhaps the most famous family of robots worldwide, the Mars Rovers.

The National Aeronautics and Space Administration's (NASA's) Jet Propulsion Laboratory (JPL), managed by the California Institute of Technology (Caltech) engineered the square construction of Hedgehog to use its embedded flywheels to propel it by flipping to another position much like dice on a crap table.

NASA's Hedgehog robot, built at NASA's Jet Propulsion Laboratory (managed by California Institute of Technology–Caltech–Pasadena, California), was specifically designed to navigate the uneven terrain of an asteroid or comet, flipping itself over and over by braking one or another of the six inside spinning flywheels–one for each surface. Hedgehog is studded with spikes that protect the robot's body from the terrain and act as feet while hopping and tumbling. Image credit: NASA/JPL-Caltech
