Project cranos™ / ISS
What if a robotic exergame system originally developed for rehabilitation on Earth could help astronauts stay strong – physically and emotionally – during space missions?

cranos™ turns proven clinical technology into a modular training solution for microgravity. It’s light, space-ready, and emotionally human – not just a machine, but a mission.

Inspired by Marco Sieber’s medical background, this project is a Swiss gift to the astronaut community – supported by maxon, SUPSI ResLab and others.
