If, like me, you have a liking for clever mechanical approaches to KAP you might like the Geneva drive, developed for early cinema projectors, allowing the film to be held briefly in the gate before the next frame is moved on. A splendid way to create a geared intermittent rotary drive from a slow rotating continuous source like a dumb servo.
I can certainly see a KAP use for such an elegant old mechanical design. I know current autoKAPs do this with electronics but this is just so lovely.
And thanks to Wikipedia for such a well prepared animation.Geneva Drive
PS I'd love someone to fabricate a few of these for AutoKAP. (I'd pay for a couple myself.)
