I'm trying to convert rotational motion of an axel into lateral so that the brown pieces slide back and forth on the red tiles. The device has to be under those red rails. The problem is that I need about 10 of them to move right after each other on a single axle. I think a gear/rack combo in white wouldn't allow for that timing. I was also thinking about a piston shaft, in the lime green.
Any ideas? I figured I'd ask before trying to find the pieces for the blue and green scissor setup.
