Soft robotic fish combines high-speed swimming with 3D maneuverability

An electrohydraulically actuated soft robotic fish developed by the Shenyang Institute of Automation (SIA) of the Chinese Academy of Sciences achieved a measured swimming speed of 2.13 body lengths per second (about 26 cm/s) and a minimum cost of transport of 9.4 J/(kg·m), setting a speed record for soft robotic fish propelled by body and caudal fin (BCF) locomotion.
