G1

Locomotion research at a lab-budget price point

G1's $13,500 base price undercuts every other shipping bipedal research platform by an order of magnitude — H1 at $90,000, Cassie at $150,000-plus for the last academic units sold. That price sits inside a graduate-lab discretionary budget rather than a capital-purchase cycle. Unitree has publicly named MIT CSAIL, Berkeley, CMU, ETH Zurich, and Tsinghua as G1 buyers; The Robot Report tracked over 200 university orders through Q1 2025. Most published work covers whole-body RL and sim-to-real gait transfer — the same niche H1 previously dominated. Buyers accept a shorter reach and lower payload for a fifth of the sticker price.

Foundation-model motion data collection

Skild AI, 1X, and stealth groups have bought G1 fleets to generate whole-body motion data for humanoid foundation models. At $13,500 per unit the economics of a 20-50 robot data-collection pod are workable in a way they never were with H1. Manufacturer has not disclosed buyer names, but Unitree distributors confirmed multiple 10+ unit orders to The Robot Report through 2025. G1's 127 cm stature introduces a proportion mismatch versus adult-scale target hardware — data buyers re-target motion in post-processing.

Stage demos and public installations

G1 filled the 2025 CES demo circuit — Unitree's synchronized 12-unit dance routine ran on repeat at the Las Vegas booth and drew more press than any other humanoid on the floor, per Robotics 24/7. The August 2024 Wushu Festival kung-fu routine in Hangzhou went viral on Chinese social media. None of this is a durable revenue segment; it drives brand awareness at low marginal cost.

Berkeley Humanoid and open-source RL benchmarks

UC Berkeley's Humanoid project (mid-2024) trains locomotion policies on G1 using RSL-RL and Isaac Sim, then transfers zero-shot to hardware. Published controllers reach 2.0 m/s sustained walking and clear stair envelopes up to 20 cm. Berkeley picked G1 over H1 because smaller mass makes crash-recovery cheaper and the SDK exposes joint torque commands at 500 Hz. Similar benchmarks followed from CMU (StaRLING) and Stanford (Sim2Real-Bench), all standardizing on G1.

Compact-humanoid manipulation with EDU dexterous hands

The EDU configuration extends DOF to 43 by adding 3-finger dexterous hands (7 DOF per hand) and swapping in an NVIDIA Jetson Orin for on-board inference. Configured price reaches $73,900 — still under base H1, still with Livox MID-360 LiDAR and RealSense stack. Published EDU work covers pick-and-place, single-arm door opening, and light assembly. Reach stays limited by the 127 cm height; bench demos routinely raise the workstation.

G1 base release — May 2024

23 DOF, 35 kg, 127 cm, $16,000. Base compute is an off-the-shelf x86 board rather than Jetson. Ships with the same Unitree SDK2 (C++, Python) as H1 — ROS2 support community-maintained at launch. Battery 421 Wh, 120-minute nominal, no hot-swap. No dexterous hands — 1-DOF grippers at each wrist.

EDU configuration — June 2024

3-finger dexterous hands (7 DOF each), Jetson Orin main compute, RealSense depth camera, Livox MID-360 LiDAR. Starts around $39,900, reaches $73,900 with Ultimate bundle (extra battery, transport case, extended warranty). Targets manipulation labs and foundation-model data-collection groups. Fully-optioned DOF reaches 43.

ROS2 first-party support — Q3 2024

Official ROS2 Humble packages replaced the community bridge. Coverage: joint-state, IMU, LiDAR, depth-camera topics plus URDF and Gazebo/Isaac Sim descriptions. Largest post-launch software change — moved G1 from 'usable with effort' to 'default-integrated' for ROS labs.

Firmware v1.5 — walking gait update — January 2025

Sustained walking raised from 1.5 m/s to 2.0 m/s plus rough-terrain gait for indoor obstacle courses. Rolled out to base and EDU. Below H1's 3.3 m/s record — Unitree has not published a G1 sprint controller.

Sim-to-real benchmark ecosystem — Ongoing through 2026

By early 2026 G1 is the default reference for open-source humanoid RL — Berkeley Humanoid, CMU StaRLING, Stanford Sim2Real-Bench, and Unitree's MuJoCo Playground all publish G1 URDFs and pre-trained policies. Locomotion transfer works reliably; manipulation transfer remains uneven and depends heavily on hand configuration.

Unitree HQ — Hangzhou, China

Primary R&D campus. Wushu Festival routine, most CES demo footage, and January 2025 firmware validation runs originate here. Internal G1 fleet size is not public.

University research labs — global

Over 200 units shipped to university labs through Q1 2025, per The Robot Report. Publicly named: MIT CSAIL, UC Berkeley, CMU, Stanford, ETH Zurich, Tsinghua. Most labs run single units; a handful (Berkeley Humanoid, Tsinghua Advanced Robotics) run small fleets.

Foundation-model data-collection fleets — USA, China

Skild AI, 1X, and stealth-stage buyers placed 10+ unit orders per distributor confirmations. Fleet sizes and identities were not released. Fastest-growing G1 buyer segment through 2025.

CES 2025 — Las Vegas, USA

12-unit synchronized dance routine ran throughout the show. Drew more press than any other humanoid on the CES 2025 floor, per Robotics 24/7.

Authorized distributor demo units — USA, Germany, Japan

Unitree USA (San Diego), Unitree Robotics Europe (Frankfurt), and Unitree Japan run rotating demo fleets for trade shows and short-term rentals. Day rates $2,500-$4,500 depending on region — roughly half of H1 rates.

127 cm height limits reach envelope

G1 tops out at 127 cm — below waist height for most adults. Tasks around adult-scale workstations (kitchen counters, warehouse conveyors) fall partly outside G1's reach. Bench demos raise the table to compensate. No manufacturer-stated upgrade path to a taller SKU.

2 kg payload ceiling

Rated arm payload is 2 kg per side — office tools, tablets, light kitchen items. Rules out grocery bags, warehouse totes, construction-grade payload. Booster T1 and Kepler K2 offer higher payload at higher cost. Buyers needing >5 kg lift capacity should not shortlist G1.

Battery is not hot-swappable

421 Wh, 120-minute nominal runtime, no hot-swap tooling. Continuous shift work is outside the design envelope. Agility Digit covers 24/7 duty with a self-charging battery bundled into its service contract; G1 does not, and Unitree has not published a hot-swap roadmap.

No outdoor weather resilience

G1 is not IP-rated. Rain, snow, dust, sub-freezing operation outside spec. Public outdoor footage runs on dry pavement in mild weather. Sensor housings would need third-party retrofits for any precipitation. No IP-rated variant disclosed.

vs. Unitree H1

Same Unitree SDK2, same first-party ROS2 packages, same Livox LiDAR and RealSense stack in top configurations. H1 is 53 cm taller, 12 kg heavier, 5.6× more expensive. H1 keeps the sustained 3+ m/s gait record and adult-height envelope. G1 covers most of the same locomotion research at a fifth of the price. If a study doesn't specifically need H1 height, G1 wins on economics. H1 retains the edge for datasets targeting adult proportions and adult-scale on-camera presence.

vs. Booster T1

Direct compact-humanoid competitor at 119 cm and 30 kg. T1 costs $33,949 — double base G1, matching mid-tier EDU. Booster ships proprietary controllers and a thinner SDK; the ROS2 ecosystem around T1 is smaller than around G1. G1 wins on price, open ecosystem, and existing benchmark support. T1 wins on integrated hand dexterity out of the box, but has not accumulated G1's university-lab footprint.

vs. Unitree R1

R1 is the smaller Unitree sibling at 122 cm and 25 kg, priced at $4,900 — a third of base G1. Closer to a hobbyist and STEM-education platform: reduced DOF, no first-party ROS2 at launch, lighter compute. G1 stays the choice for serious research; R1 works for teaching and cost-sensitive maker projects. Shared SDK surface lets policies partially transfer to G1 — Unitree markets R1 as an entry ramp for institutions weighing G1.
