Robot Fish Control Program - Arduino/Raspberry Pi

This is an controlling program for our robotic fish, which includes read of RC signals and control of servos using Raspberry Pi.

The whole project is aimed at designing, manufracturing and testing a robotic fish used for underwater exploration with concealment. So that observation of marine creatures can be conducted without disturbance.

This github repository contains the controlling code for the controller of the robotic fish. One version is for the Arduino which uses C++. The other version for Raspberry Pi uses Python 3.

Supported Python Version

Python 3.7

What you need

• A Raspberry Pi or Arduino

• Wires

• A RC transmitter

• A RC controller

• Several servos

• RPi.GPIO libraey instsalled on Raspberry Pi

How to Use

The program is designed for Arduino and Raspberry Pi. A corresponding RC transmitter is need to connect to the controller on specified pin (written in code comments) to read in the signal. And then process through the controller to output signal to the servos. The connection between servo and controller is also included in the code comment.

Issues

The raspberry pi does not support hardware PWM due to system interuptions. Thus, without external chips, the controlling of servo is very poor.
