Hi Folks.
Was doing some reading on Elastomer Actuators (or artificial muscles). Something that would work really well in animatronics.
And I found this :)

Very interesting possibilities.

They also have a few video's on how to do this yourself

Plus another 'how to' here

Enjoy the possibilities

    Here's a fun example of an animatronic eye with dilating pupil:

    I'm curious to see how different people tackle the challenge of a dilating pupil.  I've seen it done with shutters, membranes, or bladders in the past.

    Nice, sadly no pics of the construction.

  • I posted this in another thread but I'll copy it here too for reference.
    I was watching the SWS Jurassic Party video and then I remembered reading this thread about dilating pupils. There's a great bit starting at around 2:01:45 where Jon Dawe explains how he made the dilating pupil for the T-Rex in JP1.
    I'm not sure I'm allowed to link directly to the video, so here's the link explaining how you can get access to it:
