Hi! Here's something at Brickshelf that might, or might not, be of help: (URL) pretty compact. Although it feels like a dif. and a couple of ratchets would do the same thing (but not what you're looking for). (21 years ago, 13-Nov-03, to lugnet.technic, lugnet.robotics)

(...) 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 (...) (21 years ago, 12-Nov-03, to lugnet.technic, lugnet.robotics)
