Robotics: Tesla delays Optimus external deliveries to late 2027

Tesla has pushed back its timeline for delivering Optimus humanoid robots to outside customers until the end of 2027. CEO Elon Musk announced the shift during the company’s third-quarter 2026 earnings call. He cited ongoing challenges with the robot’s hands, overall durability, and artificial intelligence as the primary reasons for the delay.

The production process has already begun at Tesla’s Fremont facility. Musk stated that early production is underway on the high-volume line previously used for Model S and Model X vehicles. While much of the infrastructure for a capacity of one million robots per year is installed, reaching that rate will take at least a year. The current target is approximately 20,000 units per week, but the timeline remains fluid due to continuing design changes.

The mechanical design of the hand remains the most significant hurdle. A Tesla Optimus engineer noted that the hand is one of the hardest hardware areas to perfect. Custom gears also present reliability concerns. Musk explained that the fingers must be soft enough to handle delicate objects while withstanding constant wear. Unlike human skin, the robot cannot heal, making durability a critical engineering challenge.

Artificial intelligence presents a different set of obstacles. Tesla lacks the large fleet of robots needed to collect real-world data, a resource available for its vehicle self-driving programs. To bridge this gap, the company plans to build between 10,000 and 20,000 robots for an internal training program called the Optimus Academy. These units will practice tasks to improve generalization. Tesla also intends to integrate its AI5 chip into Optimus by April 2027.

Musk promised a video within one or two months showing the robot performing unscripted tasks. He argued that many current demonstrations rely on pre-programmed routines that may not hold up in real-world conditions. The company’s shareholder letter for the quarter described the current output from the Fremont line as the first production-quality bots manufactured by Tesla.

Competitors in the humanoid sector are facing similar technical barriers but have shown distinct progress. XPeng activated an automated production line for its IRON robot in Guangzhou in September. More than 80% of core processes are automated, and the company targets mass production by the end of 2026. Deliveries for XPeng are expected to begin in the first half of 2027, initially in stores and malls.

Boston Dynamics, a Hyundai subsidiary, began producing its electric Atlas robot in January 2026. All deployments for this year are already committed, including work with Google DeepMind. The company opened a robot training center at Hyundai’s Metaplant in Georgia in September. Atlas is currently learning to sequence car parts for assembly lines. Hyundai plans to deploy 25,000 robots across its plants in the coming years.

Musk asserted on the earnings call that no other company is even close to Tesla in general-purpose humanoid development. However, competitors like XPeng and Boston Dynamics have comparable or slightly ahead timelines for initial deployments. The industry continues to grapple with the same core issues: creating hands that survive real work, ensuring reliability, and developing AI that can handle new tasks without extensive retraining.
