"Automated Checkers" works by typing in the location of the checker you
want to move, and then typing in the square you want to move it
to. The program will check to make sure that the move is legal
(another checker isn't in that spot, moving too far, not moving
diagonally, etc.) The mechanism will then move over to the
selected checker, move down and activate an electromagnet to pick up
the checker, move over to the selected square, move down, and
deactivate the electromagnet to release the checker.
