What is Tesla Optimus? It is a general-purpose humanoid robot under development by Tesla, Inc., first announced at the company’s AI Day event on August 19, 2021.
The machine, officially called Tesla Bot, is built to walk on two legs, work with a pair of arms and hands, and operate in spaces designed for people. According to Wikipedia’s overview of the projectElon Musk has said Optimus will “probably” be the biggest product ever, not just Tesla’s biggest product. Whether it lives up to that billing is one of the most argued questions in robotics.
Key Facts
- Tesla Optimus was announced at Tesla’s AI Day on August 19, 2021; the first working prototypes appeared in September 2022.
- The planned robot stands 5 ft 8 in (173 cm) tall, weighs 125 lb (57 kg) and carries a 2.3 kWh battery.
- Musk estimates a consumer price of $20,000 to $30,000, but no Optimus has been sold to the public.
- As of the April 22, 2026 earnings call, first-generation production lines were being installed at Tesla’s Fremont factory, designed for 1 million robots a year.
- The name comes from Optimus Prime, the lead character in the Transformers media series.
What Is Tesla Optimus Designed to Do?
Tesla Optimus is designed as a general-purpose robot: a machine that can perceive its surroundings, avoid obstacles, pick up objects and learn new tasks through AI training, according to a detailed guide from Optimusk.blogUnlike industrial arms that perform one fixed job, Tesla wants a robot flexible enough for factories, warehouses and eventually homes.
The reasoning is simple. The world is built for humans, with human-height shelves, human-shaped tools and human-width doors. A robot with a human form can use that world without redesigning it.
Optimus runs on the same AI architecture behind Tesla’s Full Self-Driving software, a vision-only system that uses cameras and neural networks instead of LiDAR. At the 2024 “We, Robot” event, Musk described the ambition in broad terms.
In practice, Musk has framed the near-term use as factory work, saying Optimus would handle tasks that are boring, repetitive or dangerous. Robots joining human workers fits a broader shift toward automation that we cover in our guide to digital tools in modern work and education
How Has Tesla Optimus Developed Since 2021?
Tesla Optimus has moved from a dancer in a spandex suit to robots working inside Tesla’s own factories. The path included public skepticism, teleoperation controversies and a leadership change in June 2025, when program head Milan Kovac resigned and autopilot chief Ashok Elluswamy took over, according to Wikipedia.
| Date | Milestone |
|---|---|
| August 19, 2021 | Musk announces Tesla Bot at AI Day. A dancer in a spandex suit stands in for the prototype. |
| September 2022 | A prototype walks onto the stage at Tesla’s second AI Day and waves. |
| December 2023 | Optimus Generation 2 debuts: slimmer, faster, with redesigned hands offering 11 degrees of freedom. |
| October 2024 | Robots mingle with guests at the “We, Robot” event. Bloomberg later reports they were remotely operated. |
| June 2025 | Program head Milan Kovac resigns; Ashok Elluswamy replaces him. |
| December 2025 | Optimus appears in London on December 13 and Berlin on December 20, greeting visitors and handing out popcorn. |
| April 22, 2026 | On the Q1 earnings call, Musk says the Gen 3 unveil is pushed “closer to production” and lines are being installed at Fremont. |
| October 2026 | Output reaches several hundred units per week, still short of the roughly 1,000-per-week year-end goal. |
What Can Tesla Optimus Do Today?
Today’s Optimus can walk with obstacle avoidance, sort battery cells on Tesla production lines, pick up raw eggs without breaking them, fold shirts in lab conditions, wipe tables and respond to basic voice commands. A December 2024 video even showed the robot crossing uneven terrain and catching itself after a slip, relying on sensors and a neural network rather than remote control, as Built In reports
The limits are just as well documented. Many public demonstrations relied on teleoperation, meaning humans controlled the robot remotely. Viewers spotted a gloved hand guiding a 2024 shirt-folding video, and Bloomberg reported that the mingling, bartending robots at the “We, Robot” event were operated by people.
On the Q4 2025 earnings call in January 2026, Musk acknowledged the robots were “not doing useful work yet.” The first production units are routed to Tesla’s internal “Optimus Academy” for training rather than sale, and fine motor tasks such as cooking or handling complex garments remain aspirational, per Optimusk.blog.
How Much Does Tesla Optimus Cost?
Musk has estimated that Optimus will eventually cost between $20,000 and $30,000, a figure he gave at the “We, Robot” event in October 2024. He has described the long-term goal as a robot priced “less than a car.”
That price remains a target, not a sticker. No Optimus is for sale, and Tesla has not announced a retail date. For context on how the target compares with Tesla’s actual vehicle pricing, see our guide to what a new Tesla costs, including discounts and buyer tips
Tesla Optimus Specs: Size, Strength and Hands
The specifications below combine Tesla’s 2021 AI Day presentation with figures reported by Built In and Wikipedia. Some are planned values, since a final consumer model does not exist yet.
| Spec | Figure |
|---|---|
| Height | 5 ft 8 in (173 cm), planned |
| Weight | 125 lb (57 kg), planned |
| Battery | 2.3 kWh |
| Deadlift capacity | 150 lb |
| Carry while walking | 45 lb at 5 mph |
| Hand degrees of freedom | 11 (Gen 2, 2023); 22 in the hand shown November 2024 |
| Price target | $20,000 to $30,000 |
The hands are the program’s hardest problem. Tesla’s newer hand design houses its actuators in the forearm, a biomimetic approach that mirrors human anatomy. Musk has also said the unreleased Tesla AI5 and AI6 chips will power Optimus, and that the robot needs enough onboard intelligence to “still do useful things, even if it loses connection,” similar to how Tesla cars drive without cellular service.
How Does Tesla Optimus Compare to Other Humanoid Robots?
Tesla Optimus is far from alone. Rivals such as Figure, Boston Dynamics, Agility Robotics, Apptronik and 1X are pursuing humanoids with different focuses, according to Humanoids Daily’s robot registryTesla’s edge, if it has one, is manufacturing
