Tesla's Optimus Humanoid Robot Mass Production Nears

Tesla is moving Optimus humanoid robot production from prototype runs toward genuine mass manufacturing, and Taiwan's supply chain is where much of the physical hardware will originate. Two Taiwanese companies, Mirle Automation and Asia Optical, have begun or are preparing to begin supplying critical components, according to a report from Taiwan's UDN published in June 2026. The development signals that Tesla's robotics ambitions are no longer just a roadmap item but an active procurement reality.

Which Taiwanese suppliers are involved, and what are they making?

Mirle Automation is already shipping harmonic reducers and joint modules to Tesla. These are the precision mechanical parts that give a robot's limbs controlled, repeatable motion, and sourcing them at scale is one of the harder manufacturing problems in humanoid robotics. Mirle has also formed a joint venture with China's Shenzhen Kedali Industry, siting the operation in Rayong, Thailand, an established industrial hub. That facility is expected to produce harmonic reducers, robotic actuators, and other precision components, and because it will use an existing Kedali facility, mass production could begin relatively quickly.

Asia Optical's role is different but equally specific. The company will supply the optical components that function as Optimus's vision system, drawing on its spherical and aspherical lens technology. Asia Optical expects mass production of these newer products to begin in the second half of 2026 and continue into 2027, a timeline that tracks closely with Tesla's own stated production schedule.

The activation of a named Taiwanese supply chain for precision actuators and optics is the clearest sign yet that Optimus is transitioning from demonstration hardware to a product Tesla intends to build in volume.

What are Tesla's production targets for Optimus?

Elon Musk described Optimus 3 in March as the most advanced robot in the world, and said low-volume production could begin in the summer of 2026, with high-volume production starting in 2027. At Tesla's 2025 annual shareholder meeting, Musk stated that the company was building a one-million-unit production line in Fremont, calling it Line One, and planning a ten-million-unit-per-year line at Gigafactory Texas. Those are extraordinary numbers for any manufactured product, let alone a humanoid robot, and the industry will be watching closely to see whether the supply chain can keep pace.

Why does this matter for the broader robotics industry?

The activation of a Taiwanese supplier network for Optimus carries implications well beyond Tesla. Taiwan's precision manufacturing ecosystem, already central to semiconductors and consumer electronics, is now being drawn into humanoid robotics at scale. Suppliers that build competency making harmonic reducers or vision optics for Tesla will be positioned to serve other humanoid robot makers as the market grows. That creates a compounding effect: the more volume Tesla pulls through these suppliers, the more mature and cost-competitive the component base becomes for everyone.

For competitors already shipping or developing humanoid robots, including Figure, Agility Robotics, and Boston Dynamics, Tesla's move to lock in dedicated supply relationships adds pressure. Component availability and cost are real constraints in this market right now, and Tesla's scale gives it leverage to secure favorable terms and production priority that smaller players cannot easily match.
