Abstract: As a main part of the Bionic propulsion technology research,the experimental measurements research of robofish is of great importance. This paper introduced a whole set of experimental instruments and devices for qualitative observation and quantitative measurement of hydrodynamics phenomena of the robofish. Now we have made an experiment to see how the apparatus affect the swimming velocity and power,another experiment to display the vertex control around the robofish. Finally we have also measured the drag during the robofish swimming.
