In this video, Sanket, the founder of Foundation, gives a behind‑the‑scenes tour of the company's design headquarters, RoboFactory 1, in San Francisco. He introduces the Phantom Mach‑1 humanoid robot, whose design goal is to interact with the world as humans do. The robot comprises roughly 500 unique parts sourced globally—about 30% from China and the remainder from the United States, Mexico, Israel, and South Korea. Sanket outlines the end‑to‑end manufacturing process, beginning with the first step, a ring‑pin housing press, and continuing through actuator assembly to the final demonstration of the robot walking. The narrative emphasizes the excitement of turning sci‑fi concepts into functional robotics.

Chapters

We didn't grow up thinking that things that we read in sci-fi we would actually be working on. To actually make it, making it walk, make it do something useful, it's probably the most fun I've ever had. I'm Sanket. I am the founder of Foundation. You're in San Francisco right now at Foundation's design headquarters that we call RoboFactory 1. So right behind me is a robot called Phantom. The goal with the robot is essentially to build something that can interact with the world the way humans do. There are close to about 500 unique parts in the robot, and a lot of them get sourced from different places. We have about close to 30% of them that still come from China, and then the rest of it are coming from US, Mexico, Israel, South Korea. Today we're going to show you how we build Phantom Mach-1 robot. Pretty much from the beginning to end, from putting an actuator together all the way up to making the robot walk. Step 1 in the process is ring pin housing press.
