Inside Tesla’s Secret Robot Factory — How the Optimus Gen 2 Is Built Step-By-Step

Inside Tesla’s Secret Robot Factory — How the Optimus Gen 2 Is Built Step-By-Step
Go behind the doors of Tesla’s hidden robot lab to see how the next generation of humanoid labor is manufactured. This industrial documentary uncovers the full Optimus Gen 2 build process, from aerospace-grade aluminum frames to fully autonomous activation.

Watch how engineers design electric muscle actuators, assemble the robotic spine and limbs, install the FSD-powered “brain,” and stress-test the robot for factory deployment. Each step is shown in real production order, just like a “How It’s Made” factory tour — but with humanoid robots built to replace repetitive human work.

What you’ll see in this video:
• precision machining of the skeletal frame
• battery “heart” fabrication and integration
• robotic hands & micro-joint dexterity assembly
• torque calibration and balance control programming
• activation stage — where Optimus stands & walks alone
• torture testing, fall resistance & reliability trials
• mass production workflow inside Giga Texas

If robots are the future workforce, this is how that workforce is built.
