Waspie_Dwarf Posted September 4, 2015 #1 Share Posted September 4, 2015 'Hedgehog' Robots Hop, Tumble in Microgravity Hopping, tumbling and flipping over are not typical maneuvers you would expect from a spacecraft exploring other worlds. Traditional Mars rovers, for example, roll around on wheels, and they can't operate upside-down. But on a small body, such as an asteroid or a comet, the low-gravity conditions and rough surfaces make traditional driving all the more hazardous.Enter Hedgehog: a new concept for a robot that is specifically designed to overcome the challenges of traversing small bodies. The project is being jointly developed by researchers at NASA's Jet Propulsion Laboratory in Pasadena, California; Stanford University in Stanford, California; and the Massachusetts Institute of Technology in Cambridge.

Waspie_Dwarf Posted September 4, 2015 Author #2 Share Posted September 4, 2015 How to Explore the Surface of a Comet or AsteroidA robot concept called Hedgehog could explore the microgravity environment of comets and asteroids by hopping and rolling around on them. See Hedgehog in action in the microgravity environment of a "vomit comet" parabolic flight.Source: NASA Jet Propulsion Laboratory - YouTube Channel Link to comment Share on other sites More sharing options...
