Nikodem "DemNikoArt" Bredlich showed off an "overcomplicated robot arm" rig he created in Blender – a part of his mechanical rigging course.
The arm moves as if in slow motion, fast and jerky, with a bunch of little details guiding its path. This project is a teaser for Phase 2 of Bredlich's course, which you can find on Patreon.
If you need more mechanical rigs in your system, check out the artist's X/Twitter, where you can enjoy an awesome leg rig, beetle wings, Mega Man X's Flame Mammoth and Storm Eagle's wing, and a cool clamp.
