For our final project in Electromechanical Design, we were tasked with creating a 3.5 degree of freedom system and chose to create a tic-tac-toe game.

We started by designing, building, and iterating our first linear slide to make sure that we had a good starting point. Then while designing and building the remaining x and y linear slides we also planned out our board. From there we laser cut the game board out of 1/8th and 1/4th MDF, attaching it all with wood glue. Then we used the water jet and surface grinded the game pieces from 1018 steel. We chose these materials because MDF was supplied to us, and there was 1018 scrap in the machine shop we could use with out magnet. All of the brackets and the rack and pinion system were all designed in SolidWorks and 3D printed at EPIC (our machine shop).

We used Arduino IDE with a MKS Base 1.0 board and an electromagnet as an end effector to pick up, hold, and then drop the game pieces.
