| contents | Integration of active matter in larger micro-devices can provide an embedded source of propulsion and lead to self-actuated micromachining systems that do not rely on any external power or control apparatus. Here we demonstrate that Janus colloids can self-assemble around micro-fabricated rotors in reproducible configurations with a high degree of spatial and orientational order. The final configuration maximizes the torque applied on the rotor leading to a unidirectional and steady rotating motion. We discuss how the interplay between geometry and dynamical behavior consistently leads to the self-assembly of autonomous micromotors starting from randomly distributed building blocks. |
