Fig. 4: Motion control of the water surface jumping soft robot.
From: Beyond surface tension-dominated water surface jumping
a Schematic illustration showing the direction control principle of the water surface jumping soft robot. b Overlaid images obtained from Supplementary Movie 3 showing the directional water surface jumping motions. c High-speed camera images showing the directional take-off process. Note that the tendon length of the left: right is 3: 1.5 (cm). d The jumping trajectories of the soft robots with different left/right tendon length ratios. e The take-off velocity and take-off angle of the soft robots with different left/right tendon length ratios. f The jumping distance and jumping height of the soft robots with different left/right tendon length ratios. g, h The overlaid images indicating the soft robot with representative left/right tendon length ratio across railings with different heights. Note that all the data captured in Fig. 4 are with the light intensity of 2.8 W (4.4 W/cm2).
