Tesla delays Optimus external deliveries to late 2027 as hand mechanics remain unresolved

The timeline for Tesla’s humanoid robots has slipped once more.

During the Q3 2026 earnings call, Elon Musk stated that Tesla expects to begin delivering the Optimus robot to outside customers around the end of 2027. He identified the robot’s hands, overall durability, and artificial intelligence as the primary areas requiring further development before commercial release. These challenges mirror the hurdles facing every major player in the humanoid robotics sector, despite Musk’s assertion that no competitor is close to Tesla’s progress. However, the production milestones of rivals like XPeng and Hyundai’s Boston Dynamics suggest the competition may be tighter than the Tesla CEO implies.

Tesla has commenced early production of the Optimus on a high-volume line in Fremont, a facility previously used for Model S and Model X manufacturing. Musk indicated that while much of the line designed for one million units annually is installed, reaching a rate of roughly 20,000 units per week will take at least another year. He cited ongoing design changes as the reason for this delay. A Tesla engineer noted that the hand is one of the most difficult hardware components to perfect. The fingers must be soft enough to handle delicate items yet durable enough to withstand constant wear, a challenge compounded by the fact that robots cannot heal like human skin. Custom gears also remain a source of reliability concerns.

The artificial intelligence side of the project also faces significant hurdles. Unlike Tesla’s vehicle fleet, which generates data for its Full Self-Driving system, the company lacks a large base of robots collecting operational data. To address this, Tesla plans to build 10,000 to 20,000 units for an internal training program called the Optimus Academy. The company also intends to integrate its AI5 chip into the robots by April 2027. Musk promised a video within one or two months showing the robot performing unscripted tasks, arguing that many current industry demos rely on pre-programmed routines that would fail in real-world conditions.

This latest update follows a pattern of shifting targets. In 2024, Musk suggested internal use in 2025 and high-volume external sales in 2026. By January 2025, he predicted the production of 10,000 robots that year, with thousands doing useful work by year-end, a goal he later admitted was not met. The Q3 shareholder letter now describes the new Fremont output as the first production-quality bots, implying that earlier units did not meet that standard.

Competitors appear to be making parallel or faster strides. XPeng activated an automated production line in Guangzhou in September, with plans for mass production by the end of 2026 and deliveries in the first half of 2027. Boston Dynamics began producing its electric Atlas robot in January and has committed all its 2026 deployments, including to Google DeepMind. Hyundai opened a training center for Atlas in Georgia in September, where the robot is learning to sequence car parts. Boston Dynamics also hired Milan Kovac, Tesla’s former head of Optimus, in January. While Tesla may have built the most robots, the core challenge of making them useful and reliable remains unsolved across the industry.

The shifting timeline raises questions about why late 2027 should be different from previous missed targets. As competitors adopt pragmatic approaches to dexterity and secure committed customers, Tesla’s promise of unscripted performance will be closely watched. The coming months will test whether the Optimus can move beyond being an impressive prototype to becoming a viable industrial tool.
