... effect model of the oscillating pectoral fin without considering flexible deformation is established by introducing a two-dimensional fluid ground effect model. The parameters of the influence of ground effect on the oscillating pectoral fin are analyzed. Finally, the ground effect test platform is built...

...Yong Cao; Yang Lu; Yueri Cai; Shusheng Bi; Guang Pan Purpose This paper aims to imitate a cownose ray to develop a fish robot with paired flexible multi-fin-ray oscillating pectoral fins (OPFs) and control it to accomplish vivid stable 3-D motions using central pattern generators (CPGs) and fuzzy...

...Yong Cao; Shusheng Bi; Yueri Cai; Yuliang Wang Purpose – This paper aims to develop a robofish with oscillating pectoral fins, and control it to mimic the bionic prototype by central pattern generators (CPGs). Design/methodology/approach – First, the oscillation characteristics...
