In this design, according to the principle of crank-rocker, a special four-bar linkage swaying mechanism combined with the flexible tail fin is adopted to guarantee the stable swimming of robofish. The skillful application of hall position sensors achieves the detection of critical position of the swing link, which makes it possible to detect the position of the tail fin and control the turning of robofish. For effective raising and lowering, a mechanism using a cylinder as a pump to imitate the swimming bladder is developed.

Firstly, design principles and architecture of the test model are briefly introduced. Then we focus on the design method, the components and the operational procedure of the bionic long flexible fin, the control and communication module, as well as the motion control subsystem. Finally, some conclusions are drawn from the test data and experimental results of the test model, and the necessities to improvments and further research are also proposed.

The thrust coefficients and propulsive efficiency of a two-dimensional flexible fin with heaving and pitching motion were computed using FLUENT. The effect of different locations of the pitching axis on propulsive performance was examined using three deflexion modes which are respectively, modified Bose mode, cantilever beam with uniformly distributed load and cantilever beam with non-uniformly distributed load.
