This space robot is designed to be something that would semi-automatously perform construction and repair tasks on spacecraft and habitats. I designed it with current and near future technology in mind, and real life space tech as reference - I wanted it to look unique and interesting, but also like something that could believably exist in real life.
The geometry of this robot is all created in cinematic style, using all quads and subdivision (wireframe shown in second two images). I created the textures in 8 different materials corresponding to different parts of the model, each with 1-2 UDIM tiles depending on the size of the area.
For the textures, I wanted to make it look like something that has been well used but not overly damaged or dirty (partly because you just don't get much weathering in space in general). For the decals, I added some machine-readable code blocks, as well as robot name, info, and company logos. I called this "RSARU/MC", which stands for "Remote Semi-Autonomous Robotic Unit / Maintenance & Construction", and for the company logo I used my pre-existing McCartin Aerospace Industries logo (a fictional company).
