One of the key problems in biotechnology is to transform energy into directed motion and load transport on very small scales. Hybrid devices driven by molecular motors operate only in environments that are similar to conditions for cellular life, and therefore their functionality is quite limited. We present a themosensitive hydrogel based device for directed motion which is also capable of cargo transport. The proof-of-principle device works on the same principle as the locomotion mechanism in earthworms. Earthworms move by contracting various segments which makes their body “fat” or “thin” at different points in time and space. “Fat” segments provide anchor points and allow for further extension of the “thin” parts of the body [1].
