One way to do that is to have a rubber-band/spring/shock holding "Output B" in
it's starting position. Then, you can use a differential to move both A and B.
Going forward, A will be easier to drive, so it will push A to it's limit, then
B will start moving (and stretching the rubber band).
Going backward, the rubber band will pull B back to the start first, then A will
follow.
The key is having the differential drive both, and setting B so it "wants" to be
at the starting position.
