1. What is Gomoku?

Gomoku, also known as “Five in a Row,” is a strategic board game played on a grid. The goal is to align five consecutive pieces vertically, horizontally, or diagonally before your opponent does. This simple yet challenging game is perfect for an AI project.

2. Materials and Tools Needed

To build this smart Gomoku-playing robot, you’ll need the following:

• Hexbot robotic arm
• A Gomoku board and pieces (or a printed grid with markers)
• A computer for programming
• Python programming environment
• OpenCV library for visual processing
• Servo controller (if needed for Hexbot adjustments)
• Webcam for board analysis
• Adhesive and tools for setup

3. Understanding the Hexbot Robotic Arm

Hexbot is a versatile robotic arm with precision movement, modular tools, and easy-to-use software. Here’s what you need to know:

• Features: Interchangeable heads, 0.05mm precision, and programmable APIs.
• Advantages: Simple setup, compact design, and compatibility with Python.
• Setup: Assemble the Hexbot as per the manual and connect it to your computer.

4. Programming Basics for Hexbot

Before diving into Gomoku-specific tasks, familiarize yourself with Hexbot’s programming environment:

• Install Hexbot SDK: Follow the official documentation to install the necessary software.
• Control Basics: Write a basic script to move the robotic arm and test its precision.
• Coordinate System: Understand Hexbot’s coordinate system for precise movement.

5. Setting Up the Gomoku Board

• Board Design: Use a traditional Gomoku board or create a custom grid. Ensure clear differentiation between black and white pieces.
• Camera Placement: Position the webcam above the board to capture the entire playing area.
• Calibration: Map the board coordinates to Hexbot’s workspace using calibration scripts.

6. Developing the AI for Gomoku

• AI Basics: Use a minimax algorithm with alpha-beta pruning for efficient decision-making.
• Libraries: Leverage Python libraries like NumPy for computations.
• Game Logic: Implement rules for detecting valid moves and checking for winning conditions.
• Difficulty Levels: Add adjustable levels by tweaking the search depth of the AI.

7. Integrating AI with Hexbot

• Input Processing: Use OpenCV to detect player moves from the webcam feed.
• Move Execution: Translate AI-decided moves into Hexbot commands.
• Feedback Loop: Ensure smooth communication between the AI and Hexbot.

8. Testing and Optimization

• Dry Runs: Test the robot’s movements without pieces to ensure precision.
• Error Handling: Account for unexpected scenarios, like piece misplacement.
• Speed Optimization: Balance between Hexbot’s movement speed and accuracy.

9. Troubleshooting and Tips

• Common Issues: Misalignment, slow responses, or AI inaccuracies.
• Solutions: Regularly calibrate the setup, refine AI algorithms, and ensure all components are securely connected.
• Enhancements: Consider adding voice control or remote play functionality.

10. Conclusion

Building a smart Gomoku-playing robot with Hexbot is a rewarding project that blends robotics, programming, and AI. Not only do you get to enjoy a customized Gomoku experience, but you also gain hands-on experience in multiple tech domains. Share your creation with the community and inspire others to innovate!
