Abstract
Understanding the collective motion of living systems can facilitate the protection of ecosystems as well as the development of swarm robotics. To overcome the system-specific and oversimplified issues of traditional investigation methods, we propose to use our fully steerable active particles powered by localized light fields to mimic and study the collective motion in a more controllable and realistic manner. By dynamically tailoring the laser patterns that drive the colloidal particles' self-propulsion with certain interaction rules, the active particles can spontaneously form collective structures, display density-dependent responses, and show high robustness to external perturbations.
