Motorless swimming robot uses 3D printed shape memory polymers to propel itself in water Research & Education
In a proof-of-concept study, researchers from ETH Zurich and Caltech in Pasadena, CA have demonstrated a new propulsion system for motorless swimming robots. Unlike traditional aquatic mechanisms which rely on propellants or engines to move in water, the swimming robots—made entirely from 3D printed parts—use fluctuations in water temperature to propel themselves.
