How would it close back up?
Attach another set of fishing lines to the sides, and pull it back up?
You've got me there. I suppose that answer wasn't well though through at all.
Either way, I'd still stay away from animatronics. It's a lot of work, and lots of room for error. Perhaps a tech can use a long black stick from behind to push it open via it's pivot
point.
From what I understand, you want it to open like a
book? The frame is still their but the actual sides open. I'd think it would be easier to make it in two peices, and hinge it so that the entire thing splits in half.
Perhaps use Chinese puppetry?
We needed a small
platform to split in half once, for B&B I believe, and I disemboweled a radio-controlled car, and used the motor for that. The cars I used had little boxes that received the radio signal and rotated a gear, which rotated one on the wheel, making it go.
^^Can you tell I'm not mechanically inclined?
I just taped the motor in the middle of the split, and a gear to the one side of the box, and used the remote to move it. (It was of course, on casters). Opened and closed (without any weight) in about 8.5 seconds
Even that was a
bit to mechanical for me. I'd much rather rig up some sort of pulley
system for it.
