This paper presents a bioinspired jellyfish propulsion system with a conceptual design, analysis and experimental tests. Hydrodynamic thrust of jellyfish is generated by fin vibration motion at predetermined resonant frequency. A new type of propulsion system for artificial Jellyfish nodes for the purpose of persistent, autonomous, and energy efficient surveillance is proposed employing smart actuator technology. A MFC (Macro Fiber Composite) actuator is employed for exciting a cantilever beam. The hydrodynamic propulsion is calculated for various excitation frequencies of MFC actuator based on vibration motion of the beam. A prototype of the jellyfish setup has been developed for the experimental validation of the simulation results. Simulation and experimental results demonstrated the feasibility of the proposed system and design. Swimming motion control and power consumption issues will be addressed.
