The robots can land on the moon and drive on Mars, but what about places they can not reach? Designed by engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, a four-armed robot called LEMUR (Guided Tour Mechanical Utility Robot) can climb rock faces, grabbing hundreds of small hooks at each its 16 its way around obstacles. At his last field trial in Death Valley, California, in early 2019, LEMUR chose a cliff-top road, sweeping the rock in search of ancient sea fossils that once filled the region.
The LEMUR project has since ended, but it has created a new generation of robots walking, climbing and crawling. During future missions on Mars or frozen moons, robots equipped with artificial intelligence and climbing technology derived from LEMUR could discover similar signs of life. These robots are under development, in order to perfect a technology that could one day be part of future missions in distant worlds. Learn more: https://go.nasa.gov/2SaMjyT
