Fig. 4: Characterization plots for the microrobot collectives of 120 micro-disks in different modes.
From: Microrobot collectives with reconfigurable morphologies, behaviors, and functions
a Collective radius, b mean angular velocity, c mean neighbor spacing, and d mean local hexatic order parameter for the rotation (blue), static (red) and oscillation (green) modes. e Mean chain length (black) and mean local hexatic order parameter (red) for the chain mode. f Mean speed for the GaSPP mode. Error bars in (a–f) represent standard deviations over 10 s.
