Homebrew Naughts and Crosses (Tic Tac Toe) Robot Revisited

This was made to replace my previous Tic Tac Toe robot (the huge box covered in tin foil and wires). The Robot moves first into the center square (where the rotation device is). The user then moves by putting tin foil into the box under the space where he/she wishes to move. The robot then responds by "putting/flipping" a lego marker off of the square next to it.

The robot will win/tie every time, as long as the user does not double back on themselves. If he/she does so, the robot will try and move on top of the user's move. But, since this does not happen in a normal game (unless if the person in the user's spot wants to loose) I decided it was okay to leave it as is to keep the robot minimalistic.

In fact, the design is very minimalistic with NO TRANSISTORS, MICROCONTROLLERS, OR THE LIKE. Only wires, cardboard, tape, tin foil, a (torqueless) computer fan motor, a dc motor, and various types of glue make up the entire robot.

It is my entry to Oddbot's challenge: https://www.robotshop.com/letsmakerobots/node/35296

     Take a look through the other robots that entered this contest. I find it interesting that we can find out a little about how the builder thinks through looking at their creations. For instance, my robot plays tic tac toe in a minimalistic and radial way while Rick100's is linear in movement/strategy. His robot adds pieces to move, my robot removes pieces to move. Just something I noticed as I was working on my robot =)

     I was so focused on building a circuit for this robot that the entire project suffered, as I has to incorporate (more like force it) into my design. I learned from my mistakes and created this robot =)
