Extended Data Fig. 7: Omnidirectional phototaxis of the PTV.
From: Self-regulated underwater phototaxis of a photoresponsive hydrogel-based phototactic vehicle
a, The PTV exhibits a collective movement, swimming along a light incidence illuminated with a 30° angle to the bottom, without any external support. b, Corresponding time-dependent displacement of the PTV in the x and z directions.
