A shoebox-sized wheeled robot explores the rugged terrain on the surface of the Mars Yard at NASA's Jet Propulsion Laboratory during recent tests of the Autonomous Pop-Up Flat Folding Explorer Robot (A-PUFFER) project. The robots are designed to work in groups, and could form roving teams of small robots that might one day explore the surface of the Moon or Mars. https://photojournal.jpl.nasa.gov/catalog/PIA23793
