Inspired by the pump-like function of the jellyfish, an underwater jellyfish-like robot that collects micro-sized debris was proposed. In our previous studies, the intermittent flow drawn into the bell and discharged downwards was manipulated by configuring the installment conditions of the rectifier plates, which mimic the oral arms of the jellyfish. However, thrust vectoring essential for underwater propulsion was not achieved. Therefore, in this study, to investigate the possibility of deflecting the direction of thrust by altering the plates’ installment angle in the same direction, the quasi-2D flow field generated by a pneumatic-driven jellyfish-like robot was evaluated using the PIV (Particle Image Velocimetry) technique, and the characteristic of the generated thrust was investigated.
