Tesla is auditing Chinese suppliers including Tuopu Group, Sanhua Intelligent Controls and Joyson Electronics as it prepares to scale production of its Optimus humanoid robot. The companies supply components such as actuators, joint modules and robot controllers, and had already received Optimus-related orders before the audits began. The latest checks focus on compliance, quality and production readiness, adding to earlier reviews of unit costs, overseas manufacturing footprints, tier-2 supply chains and component repeatability as Tesla works toward a $20,000 target price. Tesla has set a long-term goal of producing 1 million Optimus units annually. The company has repurposed its former Model S and Model X production line in Fremont, California, for Optimus, with Tesla’s VP of Vehicle Engineering, Lars Moravy, saying the facility will have at least 40 production lines. Tesla is also preparing a second line at its Texas Gigafactory with a long-term design capacity of 10 million units annually, while targeting approximately 50,000 units in 2026 for use across its Gigafactories. Elon Musk has said Optimus could eventually become a Von Neumann machine, a theoretical self-replicating machine that uses available resources to reproduce itself. The robot is undergoing factory training in Austin, Texas, for more complex tasks in 2026, and could reach consumer homes as early as late 2027 based on a sales timeline Musk disclosed at the World Economic Forum. Tesla shares rose 1.39% to $369.34 in Monday premarket trading.
