Nikita's plan is legal; circular-to-linear is the disk & stick, and the ball is just THERE.

AS far as using steps again, there's no requirement for everything to be one-of-a-kind. Only caveat: your paperwork tells which one counts for what points. No having two balloons and then claiming that the second one counts when the first one fails.

Would a rolling ball bearing (circular motion) that pushed a straw in a straight line (linear motion) work?

I would personally say that does not count. The ball's path is linear, so therefore it is just linear to linear. The ball is just moving down a ramp in a straight line. Can anyone else weigh in on this?

Agree.

I'm really puzzled by how difficult this give-away task has been for so many teams. It should be the easiest, most reliable one out there. Look at the side of a railroad steam engine. Power it with a weight on a string wrapped around the wheel. Simple.

Our team took my suggestion of a ball going around on circular ramp and then hitting something at the end. Practically the simplest way to solve this one.

Another great option is to use a winch system (as said by Primate). A motor spins, winds up string, pulling the string vertically

I'd be careful about this one, my regional event supervisor denied us points for that
The winch sounds like a good idea, if we had the money to get one, haha

That's very unusual. How would that be against the rules? I see no way that it doesn't qualify as circular to linear.

The winch is just a small little DC motor with a straw attached to the end Nothing fancy at all

Ball rolling around a ramp and hitting something?

In short. . . . no way.
