Ignoring the fact that you posted a picture to a non-binaries group:
Brent, The motion you are talking about is called reciprication. Reciprication is
done with an offset shaft. Look at the way a locomotive drives its wheels. The motor would only need to go in one direction, if you needed feedback, you can sense the two positions. Delay would be from either a microcontroller or a set of one-shots.
