A Experimental snapshot of underwater robotic bending propagation motion. B Experimental snapshot of underwater robotic none-bending propagation motion, black arrows indicate the underwater drag force. C Hydrodynamic drag analysis of robotic bending propagation based on motion track results., black arrows indicate the underwater drag force. D Hydrodynamic drag analysis of robotic none-bending propagation based on motion track results., black arrows indicate the underwater drag force. E Hydrodynamic drag distribution heat map during the motion of the robot. More details about comparison of the underwater robotic bending propagation and non-bending propagation are available in Supplementary Movie S1.
