Leju Robotics
Leju Robotics (Leju (Shenzhen) Robotics, 乐聚机器人) is a Shenzhen humanoid robot company founded in 2016 by Leng Xiaokun and fellow graduates of the Harbin Institute of Technology, where he earned a PhD in computer application technology. Leju launched its first humanoid, the small educational Aelos, in 2016, and the series went on to run in thousands of schools, giving the company years of experience shipping robot hardware. Early backers included Songhe Capital and Shenzhen Capital Group, and Tencent made a strategic investment of 50 million yuan in 2017. In December 2023 Leju unveiled KUAVO (Kuafu), a high-dynamic full-size humanoid with dexterous hands, which runs KaihongOS, a commercial distribution of the OpenHarmony operating system created by Huawei, and Huawei Cloud's Pangu model. Leju delivered its 100th full-size humanoid in 2025 and began operating a pilot production line in Shenzhen in April 2026, with a Foshan factory planned for mass production at more than 10,000 humanoids a year. In May 2026 its application to list on Shenzhen's ChiNext board was accepted.
💡Notable Achievement: Leju launched Aelos in 2016, unveiled KUAVO in December 2023, delivered its 100th full-size humanoid in 2025 and filed for an A-share IPO in 2026.

KUAVO 5-W
By: Leju Robotics
Launched: 2025
KUAVO 5-W is the wheeled version of Leju Robotics' KUAVO 5 general-purpose humanoid, launched with the legged KUAVO 5 in November 2025 for industrial work. It mounts the KUAVO humanoid upper body on a lifting torso and an omnidirectional wheeled base that turns on the spot, reaching from the floor to 2.6 m. Leju's spec sheet lists 836 × 548 × 2000 mm (extended), 156 kg, 40 degrees of freedom with 6-DoF dexterous hands, 500 N·m peak joint torque, 5 kg per arm and 20 kg whole-body payload, 100–2070 TOPS of compute, four depth cameras and two 2D lidars, Wi-Fi 6 and Bluetooth 5.2, and at least 8 hours of endurance. The waist rotates ±180° to cover a full circle, hand modules release quickly, and 3D visual SLAM with semantic mapping handles navigation. Leju targets warehouse tote handling, automotive and 3C manufacturing, and patrol and inspection work.
ROBAN2
By: Leju Robotics
Launched: 2025
ROBAN2 (ROBAN 2, Chinese name Luban No. 2) is a medium-size bipedal humanoid from Leju Robotics built as a teaching, research and development platform for embodied AI. Leju teased it in July 2025, and from April 2026 it has been built on Shenzhen's first humanoid pilot production line, which assembles a unit in about two hours. It comes in four versions: the Agile edition (23 DoF, five-finger hands, RK3588 compute) and Advanced editions A (23 DoF), B (25 DoF with two-finger grippers) and C (45 DoF with five-finger dexterous hands), which add lidar, a depth camera, autonomous navigation and an NVIDIA Orin NX module with 117 TOPS. It has a fall-resistant structure, a model-based plus reinforcement-learning control architecture compatible with OpenAI Gym and Stable Baselines3, simulation support in Isaac Gym and MuJoCo, hot-swap battery changes while standing, a gamepad, large-language-model Q&A, and graphical and Python programming.
KUAVO 5
By: Leju Robotics
Launched: 2025
KUAVO 5 is a full-sized modular humanoid robot from Leju Robotics designed for industrial, service, and research use. It emphasizes practical deployment through interchangeable locomotion and end-effector options, including bipedal walking and a wheel-leg variant for smoother indoor mobility. Reported specifications place it around 173 cm tall and 63.5 kg, with a one-hour walking endurance and rapid recharge. The platform is built for dexterous manipulation, multi-terrain movement, and remote or autonomous operation, making it suitable for logistics, factory handling, demonstration, and human-facing service tasks. Its modular architecture and embodied-AI orientation suggest a focus on flexibility, maintainability, and scenario-specific customization rather than a single fixed task.
KUAVO 4PRO (KUAVO-MY)
By: Leju Robotics
Launched: 2024–2025
KUAVO-MY is a full-size humanoid robot developed by Leju Robotics for research, industrial experimentation, and advanced service applications. The bipedal platform focuses on dynamic locomotion, whole-body motion control, and intelligent task execution. KUAVO-MY integrates high-precision joint actuators, real-time balance control, and multimodal perception systems to enable stable walking, manipulation, and human-environment interaction. Designed primarily for laboratories, enterprises, and innovation centers, the robot supports autonomous behaviors, teleoperation, and learning-based control through modern robotics software frameworks, making it suitable for robotics research, industrial testing, and intelligent service deployment.
