In this Instructable project, we will build a smart Gomoku playing robot with the Hexbot desktop robot arm. The Hexbot robot arm is a high precision desktop robot arm with 0.05mm high repeatability and modular design. It comes with 5 end effectors includes a pen holder, laser engraver module, 3D printer module, suction cup, and soft gripper.
Play Gomoku with Hexbot
With the high precision and up to 500g payload capability, Hexbot can be applied in some small scale industry. We can do something very cool with Hexbot, such as laser engraving our phone case and sorting different objects with the OpenMV kit and 3D printing:
Drawing a SpongeBob with Hexbot
Play "Happy Birthday" with Hexbot
Sorting M&Ms with Hexbot
Packing an iPhone box with two Hexbot
Here is the whole process of making the smart Gomoku playing robot:
Hexbot also comes with a conveyor belt and a sliding rail and we can combine them with Hexbot to build a mini production line on our desktop. Here is the Kickstarter video of Hexbot and this project is crowdfunding now, learn more about Hexbot here.

Step 1: Prepare Tools and Materials
- Hexbot Robot Arm
- Power supply
- Suction cup kit
- Soft hose
- 14-inch touchscreen
- Gomoku sticker
- Double-sided tape
- Qt Creator 5.11
- Arduino IDE
Step 2: Design and Print Chessboard Base
Masure the size of the touchscreen and the height of the robot arm base, design the keyboard base and piece box with four holes that can store 36 pieces. Print it with the Hexbot 3D printing module.
Step 3: Paste the Sticker to the Touchscreen
With the touchscreen, we can detect the status of the chessboard and send it to the computer. To get the better performance, we need to get rid of the bubble of the sticker out of the screen.
Step 4: Connect the Serial Port
Step 5: Assemble the Base to the Touchscreen
Fix the 3D-printed base and piece box on the back of the touchscreen with the double-sided tape.
Step 6: Assemble the Chessboard and the Robot Arm
Fix the Hexbot robot arm on the plate and mount the suction cup modules. Put the chess board on the plate and test the reaching area with the robot arm and adjust it if the suction cup cannot reach. Fix it with double-sided tape on the plate.
Step 7: Assemble the Pneumatic Box
Connect the pneumatic box and suction cup head with the soft hose.
Connect the pneumatic box and the robot arm with the type-C caple.
Connect the power and the serial port.
Step 8: Locate and Calibrate the Suction Cup
Adjust the Computer Resolution to Map the Chessboard
I changed the resolution into 800*600 pixel to make it map correctly from the touchscreen to the computer screen and you can change it according to your computer screen resolution.
Record the movements of the suction cup
Drag the head of the robot arm to the four ends of the chessboard, record them. Program the robot arm to get the Gomoku piece at the piece box.
Step 9: Enjoy the Game With Hexbot:D
