We have two sensors: one absolute pressure sensor which was calibrated to detect the depth of the robot underwater. One infrared sensor to detect the obstacle in front of the robot and the robot would turn when obstacle is detected.

For the control method, we use microprocessor to generate sinusoidal wave to the servo motors to control the shaft position of the motors. The shaft position would change according to the signal. There’s phase lag between motors. The fin is attached to the motors and flaps when motors adjust their shaft positions. We can control the robot by adjusting the amplitude and frequency, turning mode, etc.

Great, it's almost real.
