Abstract
Fish-like swimming could have considerableamount of energy savings while it is used for small
autonomousunderwater vehicle. But, analysis of fish motion dynamicsin the water, demands
great attention. Here, in this work,we analyze fish motion dynamics in
the water and design robotic fish which is capable of navigating in three dimensional
space with the use of pectoral fins. The robotic fish movementin a three dimensional space is
simulated in arduinoIDE . The skeleton of the fish which consists of 3-joint mechanical tail (rear
part) and two pectoral fins,are designed and fabricated. The joints are actuated by servo motors.
Experiment shows that the mechanical tail is capable of generating near sinusoidal wave through
its body. The control signals for the servo motors are generated by an onboard Atmega-328
micro controller.
