In this Instructable I will show you how to make a robot arm that plays Tic Tac Toe using a Micro Magician robot controller, 4 servos and building blocks / materials of your choice. The wiring is super simple, just plug 4 servos and the battery into the Micro Magician. There is no keypad to wire up because the controller has an IR receiver built in and uses a universal TV remote to control it.


I won't give detailed, step by step instructions for building the robot because it's physical design does not need to be exactly the same as mine. I used LOZ blocks. You can build the robot however you want using whatever blocks you have. It could also be made from Meccano or Lego.

The supplied Arduino code (see step 4) allows you to teach the robot arm where each position on the board is using the TV remote. The positions are stored in the controllers EEPROM memory. This means your robot can be any size or shape as long as the arm can reach all positions.

The program also displays the game on your PC via the serial monitor so you can play against the controller even without the robot. This is ideal for experimenting with the robot's A.I. My code is not very smart so even at the hardest level you can beat it.
