Tesla’s Optimus humanoid ramp is hitting manufacturing snags, according to The Information’s September 25 reporting. Each hand and forearm contains more than 100 screws and small components that workers still assemble by hand; some touch sensors have reliability problems; and assembly fixtures at the hand, joint, and electronics-testing stations cannot consistently align the parts, leading to more rework coming off the line. Some suppliers — many of them in China — make good parts in prototype quantities but struggle to keep quality consistent as volumes rise. Tesla has scaled from a few dozen robots per week during Q2 small-batch testing to several hundred per week in August, and managers are reportedly aiming for a continuous automated line capable of more than 1,000 robots a week by year-end, with an eventual target of about 20,000 a week. Most of the robots built so far are used internally for testing, training, and data collection; the current generation is not the commercial version, and the plan is to lease rather than sell the first units to a short list of companies whose factories resemble Tesla’s own.
Why it matters: Tesla increasingly trades on the AI and robotics narrative rather than auto margins, and hand-assembled hardware with fixture and sensor issues suggests the manufacturing learning curve is earlier than the ramp targets imply — raising execution risk around the year-end 1,000-a-week goal. Supplier quality problems at higher volumes are the classic bottleneck that turns an impressive prototype cadence into a delayed commercial rollout. And the deeper problem may be the software: The Information reports Optimus still can’t reliably generalize to new tasks, with even basic jobs reportedly taking days to train.
What to watch: whether the 1,000-a-week target holds or slips; the promised V3 reveal — due by mid-2026 per Musk and still not shown; progress on touch-sensor reliability (Tesla reportedly plans a replaceable “sensing glove” next year) and supplier quality; and whether the robots can graduate from supervised, fenced-off tasks to genuinely general work.

Discussion question: Is the Optimus ramp a temporary manufacturing learning curve, or a sign Tesla’s robot timeline is slipping?
