Herein, we present the concept of micromotors laying "breadcrumbs"; that is, these micromachines can move/return to a home position without external guidance after their external energy input is stopped. As a demonstration, TiO₂ /Pt Janus micromotors that move forward with UV light can return back following the previous path when the UV light is turned off. Such autonomy of motion opens the door for truly independent applications of micromotors in the "deliver-and-return" fashion.||URI:||https://hdl.handle.net/10356/151128||ISSN:||1861-4728||DOI:||10.1002/asia.201900004||Rights:||© 2019 Wiley-VCH Verlag GmbH & Co.
