Connect4-3D

Connect4-3D is an exciting project created by students at Sherbrooke University in Quebec, Canada. The goal of the project is to build a robotic arm that can play Connect 4 in 3D against a human. This README file contains information on how to replicate the project and includes links to all the necessary code, CAD files, and installation procedures.

Project Overview

The project is open source and is licensed under the GNU General Public License v3.0 (GPLv3). The main components of the project are:

1. The OpenCR board code for controlling the robotic arm
2. The computer code for processing the game board and communicating with the OpenCR board
3. The CAD files for 3D printing the parts
4. A Bill of Materials (BOM) listing all the non-printed materials used

Location of OpenCR Code:

1. The executable code is named stateMachineAutoOnly_copy_20230308124647 in the folder with the same name
2. The file PingMotorsID is pingning all the motors ID connected to the OpenCR board
3. The file named ServoReadLive is monitoring the live position of the first and second joint

Location of computer Code:
