I built Johnny 5 from the movie Short Circuit (1986) using a combination of TECHNIC and LEGO elements for the main frame and articulated features. Please see the full video for detailed views and functions. https://www.youtube.com/watch?v=rM-Ud8dAm6k
Will share a part list soon! Any feedback is welcome : )
I started with the treads and body hinge because I wanted Johnny 5 to be able to fully extend his 'legs' like he does at the end of Short Circuit 2. The third wheel was eventually redesigned.
Here I am just roughing out the scale for the arms and head which are later redesigned.
Johnny 5's eyebrows in this early version were more expressive in attack mode but I decided afterwards to use a technique that gave him a better default friendly appearance.
Here is the MOC next to a minifig for scale, pretty much complete except for the laser cannon and some fiddling with the neck and arms. I kind of like the thought of a Johnny 5 this big : )
Ya got me, ya dirty rat!
This is the final version, except that the arms are still (wrongly) jointed at the bottom and not the top of the shoulder. Too bad about those moss green hinges!
