I had a dream of developing an animated Christmas Holiday Season display, potentially as a fund raiser for the arts. My original idea was to use puppets as characters, but reading and investigating made me curious as to whether I could build an animatronic penguin.
This instructable concentrates on the torso, which has four degrees of freedom, allowing the figure to move about in many directions. As a goal, I wanted a penguin that could "dance".
