I agree with keeping things simple, because more things mean more chance of failure, which eventually just becomes a matter of how frequently over time. However, this is a pretty simple design. It’s a clever use of simple mechanisms. From the gif above, it’s an extra gear with a linear actuator attached. It’s not doing anything complex other than just cycling the actuator twice over the course of the full half circle –or four times a cross the entire gear if it could go all the way around. This is probably not going to be the thing that breaks, and even if it is it’s probably easily replaceable (if it became common so the parts are available).
