I started working on T08A2 / R3000 spider tank from Ghost In The Shell movie a year ago. For those who haven't seen the movie - I would highly recommend, it's one of the best sci-fi anime movies.



Scale 1:20 (roughly :))

One of the biggest problems that I had from the start was non existence of blue prints, or actually anything that would be close to that. That's why scale is approximate :) So for "blueprints" I ended up with a few things:

  • Screenshots from the movie
  • Smaller resin model from ebay, which isn't proper quality :)
  • Someone made a 3D model, which I managed to aquire. It isn't very accurate, I would say it follows movie almost...

So yeah, none of these were precise. Actually, even frames from the movie sometimes contradict itself. To make matters worse I wanted to make a model which could move, so following sizes and strength of mechanical components had to be taken into consideration as well...

Initial idea was to make the shell from a styrofoam, but during last year I bought a 3D printer, which came very handy when making these complex shapes.

That should look amazing once complete. I like the GITS designs as well. Pity most of the merchandise is a tad expensive. I do have the Jigabachi AV model though.

Oh yeah - Jigabachi is amazing too. I'm considering turning it into flying RC model as my next potential project :) But I need to get CNC machine that can work on styrofoam, because 3D printing won't do - it's way too heavy.

A little bit from inside the "brain" of the robot:



The robot has full model of itself (in order to do correct simulation) and it's calculating where to make steps in such way that legs do not collide.

A little bit from work progress:

Model in 3D printing program:


Printed parts:


Here should be some screenshots of work with sanding paper and acetone, because that's a big part of 3D printing, but about that some other time :)

Assembly of electronics (2x servos, 1x laser):


Hiding of cables inside the ammunition belt:




Painting of base color and assembly:

Holy Mackerel! This looks like the beginning of an awesome build...one that walks across the floor on its own no less! I liked Ghost In The Shell very much as well, glad to see someone doing a build from that anime. Will definitely be following this one!

Result:


"Suspension" of toes:


I hope to finish main body and the I'll be able to attach the legs. I hope that everything will work once cables are connected (fingers crossed :)) Otherwise I'll have to disassemble (read: break) and redo some parts :)) The original plan was to have ability to disassemble, but that was too complicated, so I skipped that part :)

Wow! That is some impressive engineering. What will the size of this robot be when completed?

That is absolutely awesome! Your video of it walking around the floor is also very cool.

I'll have to remember you when I get around to building my custom designed bipedal reptilian mech with a tail. :) I could use your help robotizing it.

I love this kind of stuff! :thumbsup:
