The redesign uses parametric CAD in Onshape with a modular document architecture, a custom dual-PCA9685 PCB manufactured by JLCPCB, improved silicone skin molding with a balaclava-style clamping system, and plastic threading screws instead of heat-set inserts. The animation system uses trigonometry-based servo constraint mapping and introduces a blend-shape approach for future AI-driven facial expression from speech audio, avoiding high-dimensional servo control problems. ## Full article daily.dev links to this article rather than hosting it.
