In the present project dyNomic model of the fish robot is developed with the consideration of hydro dyNomic force and interNol dyNomic of the each components. Model of the fish robot is developed with with CAD software for 3D printing to study the motion of the fish robot in underwater application. Controller is developed for motion control of the fish robot. The dyNomics performance is to be studied with MATLAB software platform. The controller performance to be tested in simulation and experimental mode with real time application using LabView software and cRIO data acquisition system.
