    T08A2 / R3000 spider lightweight tank (from GITS)

    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.

    This is almost complete frame (except "arms"/weapons) and close to complete electronics:



    Motion is controlled by RaspberryPi. Programming in C++, from scratch. It is controlled with PS3 joystick, but there are plan to have some autonomous functionality.

      Interesting project Paulius.

      I have all the Masamune Shirow comics!

            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 3dsMax:



              Model in 3D printing program:



              Model in 3D printing program (after slicing):



              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):

                That is some very impressive 3D modelling

                  Yep! Certainly this a new and different kind of modeling

                          I guess we are watching the future for scratch builders, there's gonna be a real surge in cottage-industry after-parts, if I'm not mistaken!
