Asset: Humanoid Robot Arm and Robot Pieces (Patreon)

Robot arm!! [download below] I learned so much doing this, both about rigging and anatomy. I loved the learning curve of getting started in rigging; it's really easy to get your feet wet, and just keep getting in deeper without even noticing. I still have a ton to learn but it feel good to know I could probably figure out most basic mechanic stuff that I might want to do.

Here's some test animations (looks best downloaded). It's designed to work with a Rokoko mocap rig, because it can track hands, now (more on that later)!!, So it should play nice with the rest of my workflow (and other folk's, too), and the rest of the mocap data I'm posting. My thought is if I apply mocap data to a regular character and this arm simultaneously, it should all just line up, and all I have to do is delete the original arm of the character and hey, robot arm!

The hand is parented directly to the mocap rig bones, but the arm is a separate IK chain, parented to the shoulder and solving to the wrist. I'm trying to figure out the best way to make a tutorial, because this is some really fun stuff to know! 

Honestly probably the most useful part are just the random bits on their own. I modeled a bunch of little parts ahead of time, so I could design the arm and bash stuff together without having to pause every couple minutes to model a new piece. They're fairly flexible (if you look, you'll see the same few pieces repeated over and over, but it's not obvious)! I also haven't really ever tried to model the die-cast steel look before, and I'm really into it.
