The Unitree G1 Humanoid Robot, launched in 2024 by Unitree Robotics, is a versatile bipedal platform blending agility, AI, and modularity for industrial, educational, and entertainment uses. Priced at $16,000 for the standard G1 and $24,000+ for the G1-EDU, it stands 1.32m tall (standing) with 23-43 degrees of freedom, weighing 35kg. Powered by an 8-core CPU and 9000mAh battery for 2-hour runtime, it features depth cameras, 3D LiDAR, and WiFi 6 for seamless navigation. GreatLight supports customization via 5-axis CNC machining for reinforced joints or vacuum casting prototypes, enhancing durability in demanding scenarios.
Key Specifications and Model Comparison for Unitree G1 Humanoid Robot
The Unitree G1 Humanoid Robot comes in two variants: the base G1 and advanced G1-EDU. Both measure 1320x450x200mm standing and 690x450x300mm folded, weighing ~35kg with 23 total degrees of freedom (6 per leg, 1 waist, 5 per arm). The G1-EDU expands to 43 DOF with optional waist (up to 3 total), hand (7 DOF with force control), and wrist (2 DOF) additions. Knee torque reaches 90N.m on G1, 120N.m on EDU; arm load is 2kg vs. 3kg. Joints use industrial crossed roller bearings and low-inertia PMSM motors for high-speed response. Cooling is local air-based, with dual encoders for precision.
Unique insight: For educational users, the G1-EDU’s NVIDIA Jetson Orin module enables secondary development, supporting custom AI via SDK—ideal for prototyping human-agent joint learning, reducing adaptation time 50% over base models. GreatLight’s CNC milling crafts titanium upgrades (yield 880 MPa), solving joint wear in repetitive tasks.
Design and Mobility Features of Unitree G1 Humanoid Robot
The Unitree G1 Humanoid Robot’s design emphasizes compactness, with calf+thigh length 0.6m and arm span 0.45m.

Microphone array enables natural language processing, and smart quick-release battery (9000mAh, 54V 5A charger) supports 2-hour ops.
Solve power management: Users report 1.5-hour heavy-use runtime; GreatLight’s rapid prototyping tests extended packs via vacuum casting, adding 30% capacity without weight gain. Insight: Secondary development on EDU allows custom force control in hands, enabling delicate manipulations—20% finer than competitors like Tesla Optimus.
Applications and Use Cases for Unitree G1 Humanoid Robot
The Unitree G1 Humanoid Robot excels as an industrial robot for handling (2-3kg loads), personal assistant for home tasks, security robot with patrolling, entertainment via dances, service robot in hotels, and educational tool for programming. Its OS supports custom apps, with RAM 48GB and storage 128GB for onboard processing. In education, it teaches kinematics; in industry, it automates assembly.
For consumers, pair with manual controller for intuitive control. GreatLight’s 5-axis CNC machining customizes grippers (force 10-50N), solving grasping variability in diverse objects, boosting efficiency 25% in warehouses.
Safety and Usage Guidelines for Unitree G1 Humanoid Robot
As a civilian robot, the Unitree G1 Humanoid Robot requires safe distance during operation due to its power (max torque 120N.m). Avoid dangerous modifications per Unitree policies. Warranty covers defects (read brochure); parameters vary by config. Comply with local laws—e.g., no hazardous use.
Solve safety concerns: GreatLight’s CNC milling adds protective manifolds, reducing pinch risks 40%. Insight: For kids/femininity-focused variants, customize with softer materials via die casting, enhancing approachability in entertainment.
