Fig. 3: Linear peristalsis of LSMR under laser scanning frequency modulation.
From: Light-driven lattice soft microrobot with multimodal locomotion
a Optical microscopy images of scanning light-driven LSMR linear peristalsis (top view) and schematic illustrating the relative position of the laser (side view). b Front and end displacements in four laser scanning cycles. The blue background and yellow background in the figure represent one laser scanning cycle each. c Displacement of the front and end of the LSMR within a single laser scanning cycle. d, e Experimental images of light-driven linear peristalsis of the solid robot (300 mW) and lattice robot (50 mW). f Displacement of solid microrobot and lattice microrobot. g The average speed of solid microrobot and lattice microrobot. The initial 2 s is excluded from the analysis due to the jitter.
