Can an astronaut operate a rover with sub-millimetre precision from orbit?
In short: This video introduces the Interact Centaur, a 4x4 rover designed to be controlled by an astronaut aboard the International Space Station. It explores how remote operators can perform delicate tasks despite being hundreds of kilometres away.
The Interact Centaur features a camera head on a neck system, two force-sensitive robotic arms, and various proximity and localisation sensors. Astronaut Andreas Mogensen will attempt to guide the rover to an operations task board to plug a metal pin into a slot. This task requires extreme precision, with a mechanical tolerance of only about 150 micrometres—less than one-sixth of a millimetre.
Operating the rover from the International Space Station involves a complex communication chain. Signals must travel approximately 90,000 kilometres via geostationary satellites to reach the rover at Earth's surface. Despite this vast distance, the system allows the operator to feel exactly what the robot is doing with only a slight lag.
