Jellyfish-inspired jet propulsion and robotic implementation have drawn much attention among the scientific community. In this paper, we report a novel robotic jellyfish synthesizing mechanical structure drive and barycenter adjustment mechanism. The robotic jellyfish relies on six-bar linkage mechanisms as actuators to realize the contraction-relaxation jet propulsion motion. To imitate the real...
This paper deals with the design, construction, and motion control of a jellyfish-inspired swimming robot that uses jet propulsion for thrust generation. The robotic jellyfish consists of a streamlined head, a cavity shell, four separate drive units with bevel gears, as well as an elastic rubber skin around the drive units. In order to replicate the locomotion of jellyfish including a relaxation phase...
