Recently, the synchronization phenomena observed in living matter such as cilia has been actively studied experimentally and theoretically. In this study, we construct a simple model system composed of spheroid particles driven by optical vortex. The spheroid particles are found to exhibit self-spinning motion with tilting their long axis against the optical axis at small topological charge. We also study the cooperative motion of the particles driven by two collinearly aligned optical vortices. We also simulate hydrodynamically coupled particles on multi- circular paths and find the synchronization in the rotation.
