So you'll control your fish using a LAN cable so that you can control your fish from the surface.
In this chapter, we'll cover these topics:
- Creating a swimming robot using servos and Raspberry Pi
- Connecting an IMU unit to help the robot stay upright, and also a compass to know which direction the robot fish is going
