In this project, a fish robot was designed and implemented. Where the shape of this fish was deduced by researching the subject of fish robots and the people he worked with on this project. After researching this project, the fish robot shape was inspired by the tuna-like robot. The electrical circuit is designed through (Arduino + servo motor + IR sensor + voltage regulator) and (voltage regulator) was used to make the circuit work properly and give the required current to (servo motor), as well as add a charging circuit and control the charging of batteries through an element (Battery Management System (BMS)), as well as weights were used to make a fish robot in water. Where this was made a fish robot that can swim in any type of water with smooth movement the tail fins were used to move a fish robot and the use of the spur fins to balance the fishy robot as well as avoid obstacles (IR sensor). And use this project research in water because The Fish Robot system is simple and cheap compared to other systems.

The future of Fish Robot: The future possible works could be resumed in the points below: 1. The current design does not consider the remote wired or wireless control of the robotic fish. The radio signal could travel a long distance through the air but attenuate rapidly in water. Communication underwater is normally done through the acoustic signal. An acoustic communication modem can be added to the robotic fish to enable remote control of the robotic fish. 2. Adding a camera to the reserved space at the front of the robotic fish autonomous swimming can be achieved through image recognition algorithms 3. Adding sensors like pressure sensors to measure the depth of the fish are needed to achieve autonomous swimming. Figure
