Unitree G1 Humanoid Specs, Fully Broken Down

If you search for "Unitree G1 specs" you are probably trying to answer one question: can a $16,000-ish humanoid actually do useful work? The short answer — that is precisely why the G1 is the best-selling humanoid robot on the planet. This is the full breakdown.

Unitree G1 core specifications

Height	Approx. 127 cm (4 ft 2 in)
Weight	Approx. 35 kg (77 lb)
Degrees of freedom	23 in the body (plus hand DOF)
Walking speed	Up to ~2 m/s
Hands	Three-finger dexterous hands, 12 DOF total
Joints	Unitree M107 joint motors with high torque density
Battery	Swappable battery, ~2-hour typical operation
Sensors	3D LiDAR, depth cameras, IMU
Price	From ~US$16,000 (education/reference config); lower entry in China

The headline number is the price. The G1 is dramatically cheaper than any comparably capable full humanoid, which is what let Unitree turn a lab curiosity into a product that ships by the thousands.

Where the G1 wins

• <strong>Cost engineering:</strong> Unitree learned how to build quadruped robot dogs at scale (the Go2 is the world's best-selling robot dog) and applied the same supply-chain discipline to a full humanoid.
• <strong>Hand dexterity:</strong> 12-DOF hands make the G1 able to grab, pour, fold and manipulate objects — the core tasks that decide whether a humanoid is useful or a showpiece.
• <strong>Modular joints:</strong> the M107 joint motors are field-serviceable, which matters for anyone running G1s in labs or demos all day.

G1 vs Tesla Optimus, at a glance

Size	G1 ~127 cm / ~35 kg	Optimus ~173 cm / ~57 kg
Focus	Cost, agility, education & R&D	Full-size factory & household work
Hands	Three-finger, 12 DOF	Five-finger, human-like
Price	~US$16,000 class	Targeted far higher, not yet fixed
Deployment	Thousands shipped	Pilot production
Software	Unitree SDK + AI ecosystem	Tesla FSD-derived neural nets

The honest read: Optimus is aiming at the full-size, factory-ready end of the market, while the G1 is winning the volume game today. If the humanoid industry's "iPhone moment" is about getting to millions of units, the G1 is showing the pricing path — and China's supply chain is what makes that price possible.

Key facts to remember

• Unitree G1 weighs about 35 kg and stands about 127 cm — small, fast and cheap.
• 23 body DOF plus 12-DOF three-finger hands handle real manipulation tasks.
• The G1 is the flagship of Unitree's push to make humanoids a consumer-and-lab-scale product.
