Abstract

One of main methods for protecting nature is to use nature as an inspiration source for designing new
products for human being’s needs. Movement and maneuver in fluids is an important issue in human
activity. In this work, by inspiration from knife fish, an undulating fin for producing propulsion force are
designed and implemented. This undulating fin is a segmental anal fin, and produce sinusoidal waves
which are needed for producing propulsion force. Then, parameters of this sinusoidal wave are discussed.
In the fish robot, with using a special mechanical system, the direction of propulsive force is
adjustable for controlling of direction and depth of swimming. Then, details of wireless control system
for maneuvering and controlling of robot `s speed are presented. Finally, the results of fish robot `s
movement is discussed experimentally.
