Extended Data Fig. 9: Accuracy of motion of the PTV with different drive modes and remote manipulation performance.
From: Self-regulated underwater phototaxis of a photoresponsive hydrogel-based phototactic vehicle
a, 3D and 2D schematics of tentacle-paddling and photo-fluidic phototaxis. The PTV quickly deviates from the laser beam due to misalignment when utilizing the tentacle-paddling mode, whereas the vehicle can travel for a long distance accurately using the regulated photothermal-fluidic interaction. b, Accurate long-distance motion of the PTV. c, d, Phototropic manoeuvring of the PTV underwater (c) and photophobic taxis at the water surface (d), drawing four letters (SJTU) by solely adjusting the direction of illumination.
