This study deals with a generation method of a transverse wave on an aquatic flexible plate using throw-off elements of Bernoulli-Euler beams. At first, in order to improve the thrust of the aquatic propulsion mechanism, generation techniques of desired pitch angle of a flexible plate was derived by a matrix-based wave analysis. Then the techniques were realized, and the validity of the techniques was verified. Secondly, in order to reduce the transverse force of the aquatic propulsion mechanism, counter plate was introduced to cancel the reaction forces from both driving forces and control forces. Then the experimental results showed the vibration on the aquatic propulsion mechanism induced by the transverse force was reduced.
