A design of a bionic dolphin mechanical fish that can capture water energy

In order to design a bionic fish underwater vehicle that can capture sea current energy, this paper designs a bionic mechanical fish with dolphin shape characteristics that can collect sea current energy by studying the movement characteristics and physiological features of dolphins. When the water flow is fast, it can collect water energy through the energy capturing device in its head, and finally convert the kinetic energy of water into chemical energy stored in the battery; when the water flow is slow, the battery discharge can supply other components for normal operation. The underwater navigator uses STM32 as the control core to control the servo and motor work by changing the PWM value, and finally the underwater navigator can operate normally.
