  text: We introduce a self-propelled colloidal hematite docker that can be steered
    to a small particle cargo many times its size, dock, transport the cargo to a
    remote location, and then release it. The self-propulsion and docking are reversible
    and activated by visible light. The docker can be steered either by a weak uniform
    magnetic field or by nanoscale tracks in a textured substrate. The light-activated
    motion and docking originate from osmotic/phoretic particle transport in a concentration
    gradient of fuel, hydrogen peroxide, induced by the photocatalytic activity of
    the hematite. The docking mechanism is versatile and can be applied to various
    materials and shapes. The hematite dockers are simple single-component particles
    and are synthesized in bulk quantities. This system opens up new possibilities
    for designing complex micrometer-size factories as well as new biomimetic systems.
