Arm controls for oversized costume

[hoggworks]

Hey all,

A while ago I saw video of someone who made an arm control system that would let them essentially control the extra arms in a 4-arm suit, or the arms of a robot if they were making a robot that was larger than them. Essentially he moved an arm control thing that translated the movements (I think mechanically, but I'm not sure) to another, larger set of metal arms.

I'm drawing a blank in figuring out what such a thing might be called. I'm assuming it's a thing, but I can't look up how it's done/how to do it until I know what it's called. Help?

Are you referring to the system that the Stan Winston school used to move the arms of their robot at comic con last year?

Either the Winston School mech for Wired/SDCC or the Team Skeletonics project they based their mechanics on.

I apparently am referring to the Winston School mech system, though I didn't realize it. The video I saw was from skeletonics.com.

I wonder if there are any plans available for it.

This is a very long and in-depth look at the mechanics of it:

That's a cool Maker Fair video. The only things I've seen resembling plans are the Solidworks screen shots from their home page or a guy on Youtube that is trying to reverse engineer the arms.
