Product description: Humanoid robot - Unitree G1
Unitree G1 is an advanced humanoid robot designed to bring artificial intelligence algorithms from the virtual world into real space. Thanks to its design with approximately 23 degrees of freedom (DOF)—6 in each leg, 5 in each arm, and 1 in the waist— the robot replicates human motor skills with fluidity and precision . Its weight is approximately 35 kg and its standing height is 1320 mm , making it logistically and integration-friendly. The components used include PMSM drives with dual encoders, a knee joint torque of up to 90 N*m, and an arm payload of approximately 2 kg —all of which enable real-world manipulation tasks . A built-in depth camera (Intel RealSense D435i) and a LIVOX MID360 LiDAR sensor provide full environmental coverage and enable autonomous navigation. The robot is ready for OTA updates and operates in the WiFi 6 and Bluetooth 5.2 standards - ideal as a research, educational or prototyping platform for automation and human-assisted robots.

Precision engineering inspired by human anatomy
Unitree G1 was designed to closely replicate human motor skills and proportions . It has 23 degrees of freedom – 6 in each leg, 5 in the arms, and 1 in the waist – allowing it to perform complex, natural movements and maintain stability in various positions . The use of low-inertia PMSM motors and industrial-grade radial bearings ensures smooth, Quiet and precise operation even during dynamic changes of direction. This design combines biomechanical elegance with the strength and control needed for humanoid robotics research.
Advanced perception and spatial orientation system
By combining the Intel RealSense D435i depth camera and the LIVOX MID360 lidar, the robot gains complete 360° awareness of its surroundings. This system allows it to precisely analyze space, avoid obstacles, and react in real time . The lidar , with a 59° vertical and 360° horizontal viewing angles, provides precise data on the distance and shape of objects, enabling smooth movement even in complex environments . This sensory suite makes the G1 not just a machine but a conscious observer of space.
The Unitree G1's 23 degrees of freedom (DOF) design allows for complex, multi-joint movements.
The robot is equipped with dual encoders in its joints, and its perception is based on an integrated depth camera and 3D lidar.
Powerful dynamics and durability in a compact form
Weighing approximately 35 kg and standing 132 cm tall, the G1 combines lightness with enormous mechanical power. Its joints generate torques of up to 90 Nm, enabling dynamic movements and stable balance . The robot arm can lift up to 2 kg while maintaining full position control. Dual encoders in each joint guarantee precision even with complex movement sequences. The compact, foldable design (690 mm high when folded) allows for easy transport and use in a variety of research environments.
Intelligent communication systems and long-term autonomy
The Unitree G1 is equipped with a range of modern solutions supporting interaction and connectivity. It supports WiFi 6, Bluetooth 5.2 , a four-microphone array with noise reduction, and 5W stereo speakers , enabling natural communication with the user. It is powered by a 13-cell, 9000 mAh lithium battery , providing approximately 2 hours of operation and allowing for quick replacement. Over-the-air ( OTA) support allows for automatic software updates, allowing the robot to continuously improve its capabilities and maintain peak performance without the need for manual intervention.
