Current progress on my new R/C Tachikoma build. It'll be approximately 1/4 scale, using two main measurements as the limiting
factors: 1) The 4" mecanum wheels, and 2) Being able to fit through a 30" wide door frame while being driven via remote control.
For reference, the finished dome in the photos below measures 13" across, and the main "eye" sensor holes measuring 3-3/4" across.
The upper body dome was printed in 4 parts, and then joined together. Each section took 6 hours of print time, and ~80 grams of ABS
plastic. The support structure for the part while it was printing actually weighed more than the part itself at 110 grams. (I plan to shred
them back down for use in the filament extruder at the Makerspace to reclaim the ABS for re-use at a later date.)
First print section just finishing printing:
Dry fitting 3 of the four sections together:
Wet sanding some of the parts:
A peek underneath at the joint seams:
All four sections joined, bondo and sanding in progess:
Assembled after final primer pass and 600 grit wet sanding:
The finished build should have synchronized eye movement, individual arm and claw open/close controls, body leaning/twisting/bowing/rearing,
and abdomen rotation/wiggle. The mecanum wheels will allow for sideways movement in addition to the normal forwards/reverse/turning abilities.
I will also be putting in a two-way audio system and a FPV setup for stand back "PUSH the Trash Can" style interaction at conventions.
