Inspired by the Aliens Power Loader.
I wanted to have the same functions as in the movie using Technic linear actuators and gears. It proved to be quit difficult but was a fun challenge. Most of the movements are there, and I was pleased about that, but the overall look is something to be desired :/ :)
Up and down movement at "shoulders" using large LA's
Loose, angled movement at "shoulders" using power joint
Up and down movement at the "elbow" using small LA's
360 movement at "wrist" using gears and turntables
Manual claw closure
Loose movement at "hip" and "ankle"
Opening protective cage
Sorry. No working torch or Sigourney Weaver ;)
