Jet Propulsion Laboratory, one of NASA’s top research facilities, is currently investigating whether it is feasible to design a wind-powered clock-work rover for Venus, tentatively named Automaton Rover for Extreme Environments (AREE). The basic concept was conceived by Jonathan Sauder, a mechatronics engineer at JPL.
AREE is designed to function on Venus’s surface without electronics, because the searing (470°C) and crushing (92 bar) atmosphere destroys such components quickly. Fortunately, the planet’s forceful winds can power Savonius wind turbines that provide the required mechanical energy for ground propulsion and on-board devices, for example a mechanical computer. Ergo, AREE is a clock-tech design made of hi-tech materials able to survive in that hellish environment for months.
AREE communicates with a Venus orbiter by a contraption of radar-reflective panels that can be set at various angles. The orbiter broadcasts a radar signal that is reflected back from those panels; the received “image” is then decoded by the orbiter. This simple device is comparable to Morse code or 18th-century semaphore telegraphs. (Also, check the movie The Martian where a stranded astronaut devises a similar method to communicate with Earth.)
