The Unitree G1 Waist is the central waist and torso connection module of the humanoid robot Unitree G1. This assembly forms the mechanical and structural link between the upper body and lower body and plays a key role in balance control, motion transfer, and overall body stability during operation.
The pictured module features a robust black protective housing with an integrated central drive and transmission system. Internal actuators, gear mechanisms, sensors, and control components are enclosed within the compact structure, while external cable leads provide connection to the robot’s main control and power systems.
The waist module enables essential humanoid movements such as torso rotation, bending, posture adjustment, and dynamic weight shifting. Its rigid yet lightweight construction makes it suitable for continuous use in service robotics, research, development, and advanced motion applications.
