LEGO MINDSTORMS EV3 tic-tac-toe playing robot

TIC TAC TO3 is a LEGO MINDSTORMS robot with artificial intelligence

A LEGO robot that plays tic tac toe

This EV3 project allows you to build a robot that plays the famous tic tac toe game. Its built-in artificial intelligence allows it to never lose a match. At worst, it can tie against the human player. The TIC TAC TO3 robot was designed years ago, and it was even featured on Italian TV! To play with it, you need 5 balls of each color; you can use any glass marble with a diameter of  14mm, or Zamor spheres (the EV3 set includes just 3 of them), or LEGO GBC balls.

You can build this robot using a single LEGO MINDSTORMS EV3 retail set 31313.  Click the button below to get the building instructions!
