Tesla pushes Optimus robot rollout to late 2027

The race to build useful humanoid robots is facing a significant speed bump. Tesla has officially moved the timeline for delivering its Optimus robots to outside businesses to the end of 2027, a shift that acknowledges the complexity of the engineering hurdles still ahead.

During the company’s Q3 2026 earnings call, Elon Musk stated that the robot’s hands, overall durability, and artificial intelligence require substantial work before they are ready for the market. While Tesla has begun early production on the high-volume line in Fremont, California, where Model S and Model X vehicles were previously built, the transition to full-scale manufacturing will take at least a year. The goal is to reach a rate of 20,000 units per week, but design changes are still occurring. Musk emphasized that the first external deliveries will go to industries performing dangerous, repetitive, or 24/7 tasks.

The hand remains the most difficult component to finalize. Engineers note that the fingers must be soft enough for delicate handling yet durable enough to withstand constant wear, a challenge compounded by the fact that robots cannot heal like human skin. Additionally, custom gears are raising reliability concerns. On the software side, Tesla lacks the massive fleet of robots needed to collect data for its AI. To solve this, the company plans to build 10,000 to 20,000 robots to practice in an "Optimus Academy" and expects to integrate its AI5 chip by April 2027. Musk also promised a video within the next couple of months showing the robot performing unscripted tasks.

This delay follows a pattern of shifting timelines. In 2024, Musk suggested high-volume production for other companies could happen in 2026, but those hopes were dashed. Last month, reports indicated that while Tesla had ramped up production to hundreds of units weekly, the robots struggled to generalize to new tasks and suffered from reliability issues in the hands and forearms. The company’s recent shareholder letter now describes the current output as the first "production-quality" units, implying that previous models fell short of that standard.

Musk claimed on the call that no competitor is close to Tesla in general-purpose humanoid development. However, rivals are making steady progress. XPeng activated an automated production line for its IRON robot in Guangzhou in September, with plans for mass production by the end of 2026 and deliveries in early 2027. Meanwhile, Boston Dynamics has committed all its 2026 Atlas deployments, including to Google DeepMind, and is training the robots at Hyundai’s Georgia plant. Boston Dynamics has also taken a pragmatic approach by prioritizing sturdy industrial grippers over complex human-like dexterity.

Tesla’s next move is to deliver on that promised video of unscripted robot work. If the footage demonstrates genuine capability, it could validate the new 2027 timeline. Until then, the industry remains in a state of cautious progress, with every major player grappling with the same fundamental issues of reliability and AI generalization.
