Tesla Optimus V3 (Gen 3): 37 joints, 22 DOF hands, mid-year debut confirmed on Weibo

Tesla dropped the Gen 3 spec sheet on its Weibo account on April 23 — the first time the company has committed to a real timeline and hardware numbers for V3. It’s a 57 kg humanoid robot that walks at 1.2 m/s, carries 37 joints (nine more than Gen 2), and runs brand-new hands with 22 degrees of freedom, up from 11.

What’s actually new

The story isn’t the walking speed. It’s the hands. Gen 2 could wave; Gen 3 is built to cook, assemble, and handle tools. Each forearm packs 25 linear actuators — 23 for the hand, 2 for the wrist — arranged in concentric rings around a central rotary. 2.3 kWh battery, 10-12 hours of runtime, 20 kg payload. Musk framed it as Tesla’s future highest-volume product, not a research demo.

Why the timing matters

Mass production kicks off Q3 2026 — July to August — on converted Model S/X lines. Target: 1 million units/year by late 2026, scaling to 10 million at Gigafactory Texas. That’s the most aggressive humanoid ramp anyone has publicly committed to.
