For such a short movement, I would look at some sort of cam on the end of a servo...

One source that forum members have spoken highly of is Pololu.

This servo looks like it might be a possibility, depending on the weight distribution on the pivot.

This one will definitely have the required torque.

The exact mount angles and geometry for the servo mount/arm will require some planning, but you can work that out on a mockup before you start cutting on your CP.

Found a motor to fit that lego actuator, but it is slow. 1 mm per second. Too slow for what im looking at doing.
Firgelli makes a motor and lego type actuator combined. 22 mm per second. Cant find a price, but one website warned it was a nice price.
This link has both above mentioned devices, scroll down to near bottom of page:

Hmmm, link doesnt work from here, although I got right to it from google. Oh well, its on their homepage somewhere, if you want to find it.
