| Hello, I'm looking for a mechanical (non-robotic) solution to a technic problem I'm facing. (I crossposted to robotics, cause you guys think about gears all the time, too. Plus, you're really smart and stuff.) My input is a constantly rotating (...) (23 years ago, 2-Nov-01, to lugnet.technic, lugnet.robotics)

| I happened upon a similar requirement some time back and discovered that (Technica ref (URL) gears - Knob wheel 32072 are able to "mesh" like gears (ie rotating in the same plane) providing an intermittent drive. These parts have shown up in a (...) (23 years ago, 2-Nov-01, to lugnet.technic, lugnet.robotics)
