Reconfigurable self-assembly of photocatalytic magnetic microrobots for water purification.

ABSTRACT: The development of artificial small-scale robotic swarms with nature-mimicking collective behaviors represents the frontier of research in robotics. While microrobot swarming under magnetic manipulation has been extensively explored, light-induced self-organization of micro- and nanorobots is still challenging. This study demonstrates the interaction-controlled, reconfigurable, reversible, and active self-assembly of TiO₂/α-Fe₂O₃ microrobots, consisting of peanut-shaped α-Fe₂O₃ (hematite) microparticles synthesized by a hydrothermal method and covered with a thin layer of TiO₂ by atomic layer deposition (ALD). Due to their photocatalytic and ferromagnetic properties, microrobots autonomously move in water under light irradia
