From a product part to a research question
stock3d pairs interactive 3D models of products with sourced directories of public companies: 100 for humanoid robots, 54 for smart glasses, 124 for AI server racks and 65 for quantum computers. The purpose is to help investors understand where a company participates in a product’s value chain, how the technology works, and what the available evidence does—and does not—establish.
Each model is an educational concept. Its components represent useful engineering ideas; it is not a replica of a commercial product or a verified procurement list. The company lists are curated, not exhaustive.

Scope and accountability
Each product has its own evidence scale. For humanoid robots we distinguish explicit humanoid evidence, broader robotics products, adjacent technology and upstream enablers; for smart glasses, explicit smart-glasses evidence, XR products, adjacent technology and upstream enablers; for AI server racks, explicit AI-rack evidence, data-center products, adjacent technology and upstream enablers; for quantum computers, explicit quantum-computing evidence, lab and test products, adjacent technology and upstream enablers. We also separate a company’s business mix from the strength of its application evidence. None of these is an investment recommendation.
