The Pop-Out mechanism was incorporated into our device as our coolness factor. The coolness factor is what helps in distinguishing one team from the other.
The Pop-Out variant of Connect Four enables a player to pop chips of his/her/(its) own colour only, from the last row of the grid. This causes the chips above to fall down one position, changing the alignment with the rest of the board and hence changing the possibilities of a connection.
The Pop-Out Mechanism
The Pop-Out mechanism is a simple slider-crank mechanism. It is attached to the underside of the carriage and is level with the last row of the game board. A servo motor screwed onto the carriage drives a crank. The crank drives a connecting rod, which finally causes the slider to move in a straight line. The slider pops the chips out of the last row.
