The Tesla Optimus, also referred to as the Tesla Bot in early materials, is a general-purpose bipedal humanoid robotic platform developed by Tesla, Inc. Announced in August 2021 at the company's AI Day event by chief executive Elon Musk, the platform has progressed through three generational iterations. The current Optimus Gen 3, announced at the 2026 Abundance Summit on March 12, 2026, was described by Musk as being in the final stages of completion, with production announced to begin in summer 2026 and high-volume production targeted for 2027.

Version history
Optimus Gen 1 (2022)
The first Optimus prototype was unveiled at Tesla's second AI Day event on September 30, 2022. The prototype demonstrated basic bipedal locomotion and waving. Gen 1 was widely characterized as an early-stage engineering demonstrator rather than a production-representative unit.
Optimus Gen 2 (December 2023)
Optimus Gen 2 was announced in a video release in December 2023. Gen 2 introduced substantial improvements in mass reduction (approximately 10 kg lighter than Gen 1), faster walking speed, and improved balance. The hands were redesigned with tactile sensing, and the platform demonstrated fine manipulation tasks including handling eggs without damage.
Optimus Gen 3 (2026)
Optimus Gen 3, disclosed in preliminary form at the 2026 Abundance Summit, introduces a revolutionary hand system with 22 degrees of freedom per hand and 50 actuators across both hands using a biomimetic tendon-driven design. Gen 3 stands approximately 5 ft 8 in tall and weighs around 125 lb. The platform is constructed primarily from lightweight aluminum and plastic. Sensor architecture uses a vision-only approach without LIDAR or radar: eight autopilot cameras provide 360-degree awareness with stereo depth estimation, augmented by foot force-torque sensors and ultrasonic proximity detection. Gen 3 was described as being in the final stages of completion at its March 2026 unveiling.
Specifications (Gen 3)
- Height: approximately 173 cm (5 ft 8 in)
- Mass: approximately 57 kg (125 lb)
- Hand DoF: 22 per hand, 50 total actuators
- Sensor payload: 8 vision cameras, foot force-torque, ultrasonic proximity
- Structural materials: aluminum and plastic
- Compute: Tesla-designed neural inference silicon derived from the FSD platform
Use case
The Optimus platform is positioned as a general-purpose, multi-task humanoid. Tesla has characterized the target application envelope as ranging from Tesla's own manufacturing operations (where earlier Optimus units have already been deployed for parts sorting, battery cell handling, and limited assembly) to a broader consumer and enterprise market that includes light industrial handling, materials transport, and eventually domestic tasks. The general-purpose framing distinguishes Optimus from platforms positioned more narrowly for heavy industrial (Boston Dynamics Atlas), logistics (Agility Digit), or domestic (1X NEO) roles.
Deployment status
Optimus units are operating in Tesla's own manufacturing facilities in Fremont, California, and at the Austin Gigafactory, performing parts sorting, battery cell handling, and limited assembly tasks. External deployment beyond Tesla's own facilities has not been broadly announced as of mid-2026. Gen 3 production is announced to begin in summer 2026, with high-volume production (characterized by Tesla as tens of thousands of units) to follow in 2027.
Estimated cost per unit
Tesla has stated a long-term production price target of USD 20,000 to 25,000 per unit. This target is contingent on reaching the volume scale that supports the manufacturing cost structure Tesla has designed toward. Initial units at ramp are expected to carry a substantially higher effective cost of production; the stated target reflects the eventual mass-production price rather than the initial market price.
