Control and Transport of Passive Particles Using Self-Organized Spinning Micro-Disks

Traditional robotic systems have proven to be instrumental in object manipulation tasks for automated manufacturing processes. Object such cases typically involves transport, pick-and-place and assembly of objects using conveyors arms. However, the forces at microscopic scales (e.g., surface tension, Van der Waals, electrostatic) can qualitatively quantitatively different from those macroscopic scales. These render release difficult, hence, traditional cannot directly transferred small (below a few millimeters). Consequently, novel micro-robotic designed take into account these scaling effects. Such could beneficial micro-fabrication processes biological studies. Here, we show autonomous position control passive particles floating air-water interface collective self-organized spinning micro-disks with diameter ${300}\,{\mathrm {\mu m}}$ . First, that collectives generate azimuthal flows cause orbit around them. We then develop closed-loop controller demonstrate without physical contact. Finally, showcase capability our system split an expanded several circular while holding particle fixed target. Our system’s contact-free used transporting delicate guiding self-assembly micro-fabrication.
