Tesla Optimus faces manufacturing hurdles as hand assembly delays robot rollout

Tesla's ambitious timeline for mass-producing its Optimus humanoid robot is encountering significant manufacturing obstacles. According to The Information, the company managed to produce only several hundred units per week last month—a far cry from its stated target of 20,000 weekly.

Assembly complexity slowing production#

The challenge stems partly from Tesla's decision to repurpose its Model S and Model X production lines for Optimus manufacturing earlier this year. The company is discovering that robot assembly differs fundamentally from vehicle manufacturing: individual Optimus components are far smaller and demand tighter tolerances than automotive parts.

The current V3 version of Optimus illustrates this complexity. Each robot's hands and forearms contain more than 100 screws and tiny components that workers must assemble by hand—a labor-intensive bottleneck in what should eventually become an automated process. Although these latest models are lighter and include more camera sensors than predecessors, they still lack an advanced sensing glove under development that would make touch-sensor replacement easier and improve overall durability.

Years of delays amid bold promises#

Optimus has struggled to meet delivery timelines for years, even as CEO Elon Musk has made sweeping claims about its potential, calling it Tesla's "biggest product of all time." For now, the robots remain confined to internal testing and limited internal applications rather than operating in real-world settings or under remote control.

Tesla's near-term strategy involves leasing rather than selling the robots to initial customers, using field data to refine future iterations. But getting hardware into external hands at scale remains the first hurdle.

Broader industry shifts#

Tesla faces headwinds beyond its own factory floor. Competitors are moving toward less anthropomorphic designs, and Chinese regulators have begun throttling initial public offerings for humanoid robotics firms, signaling skepticism about whether the technology hype outpaces genuine readiness.
