Tesla Optimus Height & Weight at a Glance
Here is the complete verified spec sheet for Tesla's humanoid robot, covering every generation shown publicly through mid-2026.
| Spec | Gen 1 (2022) | Gen 2 (Dec 2023) | Gen 3 hands (2024–2026) |
|---|---|---|---|
| Height | 173 cm (5'8") | 173 cm (5'8") | 173 cm (unchanged body) |
| Weight | 73 kg (160 lbs) | 57 kg (125 lbs) | Body weight not yet published |
| Hand DoF | 11 | 11 | 22 (50 actuators, 25 per hand) |
| Body DoF | 28 | 28+ | 28+ (body carried over from Gen 2) |
| Walking speed | < 2 km/h | 8 km/h (5 mph) | Not yet disclosed |
| Payload / carry | 20 kg (45 lbs) | 20 kg, 9 kg per hand | Not yet disclosed |
| Deadlift | 68 kg (150 lbs) | Not officially restated | Not yet disclosed |
👉 Every public Tesla figure agrees on one number that never changed across generations: 173 cm tall. Weight is the variable that moves — down 16 kg from Gen 1 to Gen 2.
Gen 1 vs Gen 2 vs Gen 3: Why Optimus Got Lighter
The 16 kg drop between Gen 1 and Gen 2 wasn't a diet — it was a redesign. Three engineering changes account for essentially all of it:
- Custom Tesla actuators replaced third-party units, cutting mass while increasing torque density.
- Composite materials replaced heavier metal substructures in the torso and limbs.
- A redesigned hand architecture moved tactile sensors into the fingertips instead of bulky external housings.
According to Wikipedia's Optimus entry, Optimus is officially specified to "measure 5 ft 8 in (173 cm) tall and weigh 125 lb (57 kg)" — the Gen 2 figure Tesla has stood behind since December 2023 and continues to cite as its production target.
The lighter frame isn't just cosmetic. Less mass means less torque required per step, which directly improves battery efficiency during an 8-hour factory shift — a point confirmed in technical breakdowns from Optimusk.blog's Gen 2 specification guide.
💡 Lighter isn't just a marketing line — every kilogram removed reduces the torque the leg actuators must generate per stride, which is why Gen 2 also walks 30% faster than Gen 1 despite using less energy.
Tesla Optimus Height in cm, Meters, and Feet/Inches
Tesla has kept Optimus's height constant at human scale across every generation shown to date — a deliberate choice, since a taller or shorter robot would need custom doorways, workstations, and vehicle-line clearances.
| Unit | Value |
|---|---|
| Centimeters | 173 cm |
| Meters | 1.73 m |
| Feet & inches | 5 ft 8 in |
| Inches (total) | 68.1 in |
173 cm places Optimus almost exactly at the average adult male height in the United States (roughly 175 cm), which is precisely the point — Tesla is engineering Optimus to fit existing human workspaces without any facility modifications.
Tesla Optimus Weight in Kilograms vs Pounds
If you're comparing Optimus to a person, a competitor robot, or an industrial arm, here's the full kg-to-lb conversion for both generations:
| Generation | Kilograms | Pounds |
|---|---|---|
| Gen 1 (2022 prototype) | 73 kg | 160.9 lbs |
| Gen 2 (2023–present) | 57 kg | 125.7 lbs |
| Weight saved | 16 kg | 35.3 lbs |
✔ For quick mental math: 57 kg ≈ 125 lbs. That's roughly the body weight of an average adult woman — light enough, per Tesla's own safety framing, for a person to physically overpower or restrain if something goes wrong.
Payload Capacity: How Much Can Optimus Lift and Carry?
Weight isn't just about the robot's own mass — payload capacity determines what jobs it can actually do on a factory floor.
- Carrying capacity: up to 20 kg (45 lbs) while walking
- Per-hand grip load: approximately 9 kg (20 lbs) per hand on Gen 2
- Deadlift (static lift off the ground): up to 68 kg (150 lbs), per Tesla's original AI Day 2021 specification
These figures were reiterated in Tesla's original AI Day presentation and have been referenced consistently in independent technical reviews, including Brian D. Colwell's engineering review of the Optimus patents, which traces the carrying and deadlift figures back to Tesla's original patent filings.
How Tesla Optimus Compares to Other Humanoid Robots
Weight matters competitively too — a lighter robot generally means lower energy use, faster movement, and reduced risk during human-robot interaction.
| Robot | Height | Weight | Payload |
|---|---|---|---|
| Tesla Optimus Gen 2 | 173 cm (5'8") | 57 kg (125 lbs) | 20 kg |
| Figure 03 | ~168 cm (5'6") | ~70 kg (154 lbs) | Not disclosed |
| Boston Dynamics Atlas (electric) | ~150 cm (4'11") | ~89 kg (196 lbs) | Not disclosed |
| Apptronik Apollo | 173 cm (5'8") | 72.6 kg (160 lbs) | 25 kg |
| Unitree H2 | 180 cm (5'11") | Not disclosed | Not disclosed |
At 57 kg, Optimus Gen 2 is lighter than Boston Dynamics' Atlas and Apptronik's Apollo, and broadly competitive with Figure's Figure 03 — a comparison independently noted in Robozaps' Gen 2 technical review, which describes Optimus as "lightest in class" among current full-size humanoid platforms.
👉 Lighter weight is a genuine engineering advantage here, not just a spec-sheet flex — it's the reason Gen 2 can walk at 8 km/h while its heavier predecessor topped out under 2 km/h.
Tesla Optimus Gen 3: What's Confirmed About Weight in 2026
"Gen 3" is currently a hands upgrade, not a full body redesign. As of Q2 2026, here's what's officially confirmed:
- Gen 3 hands feature 22 degrees of freedom and 50 actuators (25 per hand) — a 4.5x increase in actuator count over Gen 2's hands
- The Gen 3 body currently in use is still the Gen 2 physical frame — Tesla has not published new height or weight figures for a redesigned chassis
- Tesla began installing Gen 3 production infrastructure at Fremont in January 2026, converting former Model S/X lines
- Full-scale volume production is targeted for late July or August 2026, with a complete V3 body reveal expected close to that production start
Elon Musk confirmed on Tesla's Q1 2026 earnings call that "Optimus V3 will be unveiled closer to production start," meaning the 57 kg Gen 2 figure remains the most current official weight as of this writing — a status tracked in detail by BotInfo.ai's ongoing Optimus specification tracker.
💡 If you see a figure claiming an official "Gen 3 weight" right now, treat it as speculation — Tesla has confirmed the hand upgrade specs but has not published a new body weight.
Checklist: Verifying Optimus Weight Claims You Read Online
- Check the generation — Gen 1 (73 kg) and Gen 2 (57 kg) are frequently mixed up in articles.
- Confirm the source cites Tesla's AI Day, an earnings call, or an official Tesla demo — not a third-party estimate.
- Watch the publish date — figures published before December 2023 almost always describe the heavier Gen 1 prototype.
- Treat any "Gen 3 weight in kg" claim as unverified until Tesla's full V3 body reveal.
FAQ: Tesla Optimus Weight & Height
How much does Tesla Optimus weigh in pounds?
Tesla Optimus Gen 2 weighs 125 lbs (57 kg). The earlier Gen 1 prototype weighed 160 lbs (73 kg).
How tall is Tesla Optimus in feet?
Tesla Optimus stands 5 ft 8 in (173 cm) tall — a figure that has stayed constant across Gen 1, Gen 2, and the Gen 3 hand upgrade.
Is Tesla Optimus Gen 3 lighter than Gen 2?
Unknown so far. Gen 3 currently refers only to a new hand system (22 DoF, 50 actuators); the body is still the Gen 2 chassis, so the last official weight remains 57 kg.
How much weight can Tesla Optimus lift?
Optimus can carry up to 20 kg (45 lbs) while walking, grip roughly 9 kg per hand, and deadlift up to 68 kg (150 lbs) from the ground.
Is Tesla Optimus heavier or lighter than a human?
At 57 kg, Optimus is lighter than the average adult male (roughly 78–90 kg in the US) and close to average adult female body weight — a deliberate safety choice so a person can physically restrain it if necessary.
Summary
Tesla Optimus Gen 2 weighs 57 kg (125 lbs) and stands 173 cm (5'8") tall — 16 kg lighter than the 73 kg Gen 1 prototype, and lighter than most full-size competing humanoids. The Gen 3 hand upgrade has not changed the official body weight as of mid-2026; a full V3 body reveal is expected around the start of volume production later this year.
