Tesla Pushes Optimus 3 Toward Mass Production as Supply Chain Gears Up

Tesla is moving full steam ahead on its Optimus 3 humanoid robot, initiating supply chain partnerships as it eyes the start of mass production. According to a report from Taiwan’s Economic Daily, the company has begun working with Mirle Automation and Asia Optical — two key suppliers that will provide critical components for what Elon Musk has called “the most advanced robot in the world.”

Mirle Automation, a Taiwan-based automation specialist, will supply harmonic reducers and joint modules for Optimus 3. The company has established a joint venture with Shenzhen Kedali Industrial in Thailand’s Rayong province, where the two firms will co-produce harmonic reducers, robot actuators, and other precision components. Because the plan leverages Kedali’s existing factory space, the report suggests that volume production could ramp up relatively quickly.

On the vision side, Asia Optical is responsible for the robot’s “eyes,” leveraging its expertise in spherical and aspherical lens technology. These vision system components are expected to enter mass production in the second half of 2026 and continue scaling through 2027.

Musk offered a bullish assessment of Optimus 3 back in March 2026, describing it as the most advanced robot globally and stating bluntly: “I haven’t seen any robot demo that comes close to Optimus 3.” On the manufacturing timeline, he indicated that low-volume production could begin as early as this summer, with high-volume output kicking off in 2027.

The supply chain ramp-up aligns with Tesla’s broader Optimus ambitions. Earlier reports noted that construction has already begun on a dedicated Optimus factory at Tesla’s Texas Gigafactory, with a planned annual capacity of up to 10 million units — underscoring just how seriously the company is betting on humanoid robotics as its next major growth frontier.
