Introduction
Worked on a cosplay arm for Viktor from Arcane/League of Legends alongside Jenna and Emanuel. Demoed at the W25 Socratica Symposium by Emanuel. I co-designed the mechanical structure, selected parts such as servo motors and lazy susan bearings, and did all of the electrical and firmware design, soldering, and programming.
See the github here for the source files.
