The Unitree G1 Base is an affordable and compact humanoid robot designed for research, education, and light industrial use. Standing approximately 1.32 meters tall and weighing around 35 kilograms, the G1 Base provides a portable yet capable bipedal platform with 23 degrees of freedom, giving it human‑like movement for walking, balancing, and dexterous manipulation. Its foldable structure enhances transportability, allowing the robot to transition from 132 cm standing height to a compact folded profile for easy storage. [humanoidindex.org]

Equipped with a high‑performance 8‑core CPU for onboard computation, the G1 Base utilizes AI‑driven control algorithms that support dynamic locomotion, complex motor coordination, and reinforcement learning. The robot can reach walking speeds of up to 2 m/s, making it one of the fastest humanoids in its size class. Its joint system uses low‑inertia PMSM motors with dual encoders for highly responsive movement and improved balance. The G1 Base also supports optional dexterous hands, with configurations ranging from simple grippers to multi‑DOF three‑finger variants capable of fine manipulation. [humanoidindex.org], [1x.tech]

For perception, the robot integrates a depth camera and 3D LiDAR, enabling 360° environmental awareness for navigation, obstacle avoidance, and mapping. Additional sensors include an IMU, gyroscope, dual joint encoders, a 4‑microphone array, and temperature sensors, providing a complete multimodal sensing suite for advanced robotics research and practical field deployment. These sensors support tasks such as SLAM, object detection, and controlled interaction with real‑world objects. [1x.tech], [humanoid.guide]

The G1 Base’s power system is built around a 9000 mAh lithium battery, providing up to 2 hours of runtime depending on the task load. The robot supports fast charging via a 54V 5A charger, allowing quick turnaround times during laboratory experiments or demonstrations. Expandability options include support for the NVIDIA Jetson Orin NX for AI acceleration, ROS‑compatible software frameworks, and a Python/C++ SDK in higher‑tier EDU versions, making the G1 a flexible platform for developers and academic institutions.
