Tesla Optimus Faces Manufacturing Bottleneck Over Complex Robot Hand Assembly

Tesla's humanoid robot Optimus is facing manufacturing challenges as it scales production, with the complex structure of its robot hands emerging as a key bottleneck, according to reports on Sep. 25, 2026.

Over the past few months, Tesla has increased Optimus output roughly tenfold, from several dozen units per week in the second quarter of 2026 to several hundred units per week now. However, supplier constraints, automation equipment failures, and the complex assembly requirements of hand components are making it harder for the company to reach its target of producing 1,000 units per week by the end of 2026.
