Humanoid head & dexterous hand engineering

Wuji Tech, Shanghai · Aug – Oct 2024 · Role: mechanical engineer intern, humanoid head design and robotic hand
ROLE & KEY CONTRIBUTIONS

Mechanical engineer intern on a humanoid head and dexterous hand, delivering production-ready components.

  1. Designed a 3-DoF neck stabilizer from kinematic constraints;
  2. Ran statics simulation and CNC structural optimization for an exoskeleton arm;
  3. Endurance-tested a 20+ DoF dexterous hand and improved component tolerancing for real-world deployment.

Overview

Three months of production-oriented humanoid work: designing a stabilized neck, hardening an exoskeleton arm's structure for manufacturing, and proving out a dexterous hand's long-term reliability. The common thread is the gap between a mechanism that works and one that ships.

What I did

No photos on this page: the hardware I worked on is covered by company confidentiality, and I wasn't able to retain images. The work is described here at the level of engineering approach only — happy to discuss methodology in an interview.
