Unitree G1 Humanoid Robot

Unitree G1 Humanoid Robot: Complete Guide

The Unitree G1 is a compact bipedal humanoid robot developed by Unitree Robotics, a Hangzhou, China-based company founded in 2016.The G1 stands 132 centimeters tall and weighs 35 kilograms, with configurations spanning 23 to 43 degrees of freedom across a product family of 16 variants from the G1 Standard (demonstration-only, ~$16,000) through the G1 EDU Ultimate D (U5-1, $73,900 with full SDK, Inspire five-finger hands, and NVIDIA Jetson Orin 100 TOPS). The robot features LIVOX MID-360 3D LiDAR, Intel RealSense D435i depth cameras, WiFi 6 and Bluetooth 5.2, a 4-microphone array, and optional Dex3-1 or Inspire five-finger dexterous hands with force-position hybrid control.

The G1 has established itself as the reference platform for academic bipedal humanoid robot research: it has been used in landmark published research from Caltech, UT Austin, Cornell, Shanghai Jiao Tong University, The University of Hong Kong, and Zhejiang University, and has demonstrated world records including a 1.4-meter long jump, a side flip, and a kip-up from the ground. It appeared at the 2026 CCTV Spring Festival Gala in multiple choreographed sequences. Unitree filed for a $610 million STAR Market IPO in March 2026, with 335 percent year-over-year revenue growth reaching ¥1.708 billion in 2025 — positioning the company as the first publicly traded humanoid robotics company in China.

Background and Development

Unitree introduced the G1 as the successor to its H1 bipedal humanoid (which targeted enterprise and research at $90,000 to $150,000) with a deliberate goal of mass-market accessibility. The Robot Report's May 2024 coverage of the ICRA launch captured Unitree's manufacturing philosophy directly: "Regarding the design and manufacturing of robots, every detail is critical in order to improve performance and reduce costs," Unitree said. "Reduce the number of wires and cables, reduce the number of chips, reduce screws, etc. These may seem basic, but are actually very critical and important."

The G1 achieved its cost position through three strategies: deep vertical integration (all core components including motors and reducers are designed and manufactured by Unitree); aggressive structural simplification; and production scaling that allowed per-unit cost reductions as volumes grew. The 5,500+ units shipped in under two years validated that this cost structure was sustainable while maintaining competitive specifications.

Design and Physical Features

Compact Foldable Form Factor

At 132 centimeters standing height and 35 kilograms, the G1 is roughly the physical scale of an average eight-to-ten-year-old child. The Robot Report observed at ICRA 2024 that this compact size "effectively eliminates Unitree G1 from a practical human labor replacement, as it won't be able to reach the same work envelope as a human worker" — but this is precisely the market Unitree targeted: research labs, universities, and developers studying robotics and AI policies rather than factory production line replacement.

The foldable structure enables storage in a compact footprint and transport without specialized equipment. For research labs that need to move robots between rooms, buildings, or off-campus locations, the G1's portability is a practical operational advantage over larger industrial platforms.

23 to 43 Degrees of Freedom Architecture

The G1's DOF count varies by configuration from 23 (base Standard) to 43 (EDU Ultimate with Dex3-1 hands and 3-DOF waist):

Legs: Six degrees of freedom per leg (bilateral, 12 total) for full hip-knee-ankle articulation enabling stable walking, running, stair climbing, slope traversal, and dynamic athletic maneuvers.

Arms: Five to seven degrees of freedom per arm depending on configuration. The base models use 5-DOF arms; the EDU Plus (U2) and above add 7-DOF arm configurations providing full shoulder-to-wrist articulation.

Waist: One DOF in base and EDU Standard configurations; three DOF in EDU Plus (U2) and above for torso rotation, bending, and lean.

Hands: Zero DOF in base configurations (dummy hands); 7 DOF per hand in Dex3-1 dexterous configurations (43-DOF total); 7 DOF per hand in Inspire five-finger configurations (41-DOF total, different hand mechanism).

The DOF tier structure enables buyers to select the configuration appropriate for their research: locomotion-only research programs can use the 23-DOF base configuration; manipulation research requires the 35-DOF minimum (Dex3-1 without tactile) through 43-DOF maximum (Dex3-1 with tactile).

Physical Capabilities and World Records

The G1's performance benchmarks, established through Unitree's demonstrations and independent academic research, are among the strongest for any sub-$80,000 humanoid platform:

• Walking speed: Up to 2 m/s (7.2 km/h) — 4.5 mph, among the fastest production humanoids
• Long jump: 1.4-meter world record for humanoid robots
• Dynamic maneuvers: Side flip, kip-up from ground, cartwheels, simulated boxing
• Stair and slope navigation: Stairs (standard commercial step heights), slopes up to 25 degrees
• Fall recovery: Autonomous recovery from supine, prone, and seated positions without pre-programmed motion (demonstrated through HOST reinforcement learning research from SJTU, HKU, and ZJU)
• Medical task success rate: 90 percent in academic medical robotics studies

Technology and Specifications

Sensing System

LIVOX MID-360 3D LiDAR: The MID-360 provides 360-degree horizontal and high-vertical-angle field of view, enabling comprehensive spatial mapping and obstacle detection. This LiDAR configuration supports the G1's autonomous navigation in complex environments including outdoor terrain, office corridors, and research laboratory spaces.

Intel RealSense D435i: The D435i provides RGB-D (color plus depth) visual perception for object detection, workspace mapping, and visual servoing during manipulation tasks. In combination with the LIVOX LiDAR, the dual-sensor perception configuration covers both the structured light range (short to medium distance visual depth) and the long-range spatial mapping needed for autonomous navigation.

Force-Position Hybrid Control: The G1's actuators support force-position hybrid control — blending position targeting with force limits to enable compliant interaction with objects and environments. This control mode is essential for manipulation tasks where the robot must touch, grasp, and move objects without applying damaging forces.

NVIDIA Jetson Orin and Open SDK

EDU variants include the NVIDIA Jetson Orin NX 16GB (100 TOPS) as the primary AI compute platform. At 100 TOPS, the Jetson Orin provides GPU-accelerated inference for large vision-language-action models, visual perception pipelines, and reinforcement learning policy execution on-device. The open SDK covering Python, C++, and ROS 2 enables full programmatic access to all joints, sensors, and the compute platform — the complete development environment for bipedal humanoid research.

UnifoLM-VLA-0, open-sourced by Unitree in March 2026 on GitHub (built on Qwen2.5-VL-7B), provides a deployable manipulation baseline for G1 EDU users covering 12 task categories — enabling researchers to start from a proven manipulation policy foundation without weeks of training from scratch. BotInfo.ai notes: "Requires EDU SDK."

Applications and Use Cases

Academic Research

The G1 has become the most widely published-on commercial humanoid robot in academic literature. Published research programs using the G1 as the physical research substrate include:

BeamDojo (2025): A two-stage reinforcement learning locomotion system for challenging terrains (balance beams, stepping stones) developed by academic researchers, with strong sim-to-real transfer validated on the G1.

HOST (2025): A reinforcement learning system for autonomous floor recovery from SJTU, HKU, and ZJU — enabling the G1 to stand up from supine, prone, and seated positions without pre-programmed motions.

SHIELD (2025): A safety framework from Caltech, UT Austin, and Cornell for human-robot collaboration, tested on the G1 in unstructured outdoor environments.

The breadth of published academic research using the G1 as the research platform reflects its combination of sufficient physical capability, open SDK, and accessible price — enabling university research teams to work with physical humanoid hardware rather than simulation-only environments.

Entertainment and Public Performance

The G1 performed at the 2026 CCTV Spring Festival Gala — China's most-watched television broadcast — in choreographed martial arts sequences. Earlier demonstrations in 2025 included Unitree showcasing the G1 executing intricate kung fu forms in high-profile public demonstrations. The G1's athletic capability combined with its human-scale upper body makes it suitable for entertainment performances, brand activations, and exhibition demonstrations where visual impact is a primary requirement.

Light Industrial and Commercial Deployment

BotInfo.ai identifies the G1 EDU as appropriate for "light commercial use" beyond pure research — including visual inspection, material transport for loads up to 3 kilograms, and human-guided task assistance in structured environments. The 5,500+ units shipped globally indicate that commercial and industrial buyers have adopted the G1 alongside research institutions, though the G1's modest 3-kilogram arm payload and 132-centimeter height limit the manufacturing tasks it can address compared to larger industrial humanoids.

Medical Robotics Research

The G1 has achieved a 90 percent success rate in medical task research according to Top3DShop's compilation of independent studies. Medical robotics applications studied using the G1 include surgical assistance movements, patient monitoring interaction protocols, and medical equipment handling — research areas where the G1's compliant force control and dexterous hand options are relevant to developing the manipulation policies needed for healthcare robotic assistance.
