Veryt cool. Never thought of the roleaux triangle as something to achieve back and forth motion with a dead stop on either end.

A Mazda RX-7 can go backwards and forwards. But I get your point. Me neither :) Now it's up to you to make something with a reuleaux triangle, Raspberry Pi, pantorouter and wood gears.

Matthias, I recommend checking out mechanism 135 from “507 Mechanical Movements”. This is right up your alley.

Same here. While a circular cam might generate a sine wave, this shape generates more of a square wave.

[@TheOfficialCzex]

@@_rlb It can run in reverse because it has a transmission that allows it to do so. The engine itself does not rotate in the opposite direction.
