In the last two decades, the research on biomimetic fish robots has fascinated scientific communities’ attention progressively. With its character of high flexibility and intelligence, biomimetic fish robot has developed in the field of underwater robots. Predominately, Biomimetic robot systems are robots that mimic the structure and function of biological systems such as natural fish, cheetah, ant, kangaroo and snake etc. This paper addresses the detecting the moving objects that is earlier developed fish robot in the aquarium because we need to acquire the position to track the fish robot. This algorithm has modeled to detect the position of the fish robot using the MATLAB and Simulink. This intends to recognize the neighborhood of the fish robots using an image processing technique through video device that is camera. Here, we have applied the proposedobject tracking algorithm to control the motion of the fish robots. This algorithm used to detect the moving objects, by using this detecting position data; we compute the distance between two fish robots using mathematical expression. Then, we send this data to control and track the fish robots through RF (Radio Frequency) modem. Certainly, the performance test of object tracking algorithm has been satisfied by the proposed experimental system.
