Tesla Sets Late 2027 Target for Optimus Sales, Cites Hand Design Hurdles

The race to build practical humanoid robots is entering a more defined, albeit slower, phase as major players adjust their timelines. On the Q3 2026 earnings call, Tesla confirmed that external deliveries of its Optimus robot will begin around the end of 2027.

Elon Musk stated that the robot’s hands, overall durability, and AI capabilities require further refinement before the unit can be sold to outside customers. Tesla has initiated early production on its high-volume line in Fremont, California, where Model S and Model X vehicles were previously assembled. While the infrastructure for manufacturing up to a million units annually is largely in place, Musk acknowledged that reaching a rate of 20,000 units per week will take at least a year. This is largely because parts of the design are still in flux, particularly regarding the electromechanical components and custom gears that raise reliability concerns.

A significant portion of the delay stems from the complexity of the robot’s hand. During the call, a Tesla engineer identified the hand as one of the most difficult hardware areas to perfect. Musk agreed, noting that the fingers must be soft enough to handle delicate objects yet durable enough to withstand constant wear, a challenge compounded by the fact that robots cannot heal like human skin. On the software side, Tesla lacks a large fleet of robots to gather data for its AI, unlike its car fleet for Full Self-Driving. To address this, the company plans to build between 10,000 and 20,000 robots to train in an "Optimus Academy" and will integrate its AI5 chip into the robots around April 2027.

This timeline follows a pattern of shifting expectations. In 2024, Musk suggested high-volume external sales in 2026, and in January 2025, he predicted roughly 10,000 units would be built that year. However, Tesla’s recent shareholder letter describes the current units from the Fremont line as the first "production-quality" bots, implying earlier models did not meet that standard. Musk also promised a video within one or two months showing the robot performing unscripted tasks, aiming to distinguish Optimus from competitors relying on pre-programmed demos.

Musk argued that no other company is close to Tesla in general-purpose humanoid development. However, competitors are making steady progress. XPeng activated an automated production line in Guangzhou in September and targets mass production by the end of 2026, with deliveries in stores and malls in early 2027. Meanwhile, Boston Dynamics, which hired Tesla’s former Optimus head in January, has committed all of its 2026 Atlas deployments, including to Google DeepMind. Boston Dynamics has opened a training center at Hyundai’s Georgia plant, where Atlas is learning to sequence car parts, while Hyundai plans to deploy 25,000 robots across its facilities in coming years.

The next milestone for Tesla is the promised demonstration of unscripted tasks in the coming weeks. If the video shows the robot handling real-world variability, it could validate the late-2027 delivery target. Until then, the industry remains focused on solving the core issues of hand dexterity, long-term reliability, and AI generalization that all major manufacturers are currently navigating.
