Amirkabir University of Technology Amirkabir Journal of Mechanical Engineering 2008-6032 43 2 2012 02 20 Design, Implementation and Experiments on a Fish-Like Robot Design, Implementation and Experiments on a Fish-Like Robot 47 55 69 10.22060/mej.2012.69 FA Mohsen Siyah Mansori Ahmad Ghanbari Journal Article 2014 03 15 One of main methods for protecting nature is to use nature as an inspiration source for designing new<br />products for human being’s needs. Movement and maneuver in fluids is an important issue in human<br />activity. In this work, by inspiration from knife fish, an undulating fin for producing propulsion force are<br />designed and implemented. This undulating fin is a segmental anal fin, and produce sinusoidal waves<br />which are needed for producing propulsion force. Then, parameters of this sinusoidal wave are discussed.<br />In the fish robot, with using a special mechanical system, the direction of propulsive force is<br />adjustable for controlling of direction and depth of swimming. Then, details of wireless control system<br />for maneuvering and controlling of robot `s speed are presented. Finally, the results of fish robot `s<br />movement is discussed experimentally.
