Leju Robotics (officially Leju (Shenzhen) Robotics Co., Ltd.) is a Chinese robotics company headquartered in [[Shenzhen]], [[China]], specializing in the research, development, manufacturing, and sales of high-end intelligent [[humanoid robot]]s. Founded in 2016 by Leng Xiaokun, the company is best known for its [[Kuavo]] series of general-purpose humanoid robots. Leju's corporate tagline is "Facilitate People, Empower Society," reflecting its goal of bringing humanoid robots into everyday life.
Leju Robotics was established in 2016 by Leng Xiaokun, who was born in 1992. The company focused on developing bipedal humanoid robots with advanced locomotion and manipulation capabilities. In December 2023, Leng and his team officially unveiled the KUAVO humanoid robot (known as Kuafu in Chinese), marking the company's entry into the general-purpose humanoid robot market.[1]
In March 2024, Leju introduced the Kuavo robot at the Appliance and Electronics World Expo (AWE) in Shanghai. By July 2024, the robot was being tested at Chinese electric vehicle maker [[NIO]]'s factory for tasks including vehicle assembly and quality control.[2]
In the first quarter of 2025, Kuavo received 250 orders, surpassing the company's half-year target. The robot was deployed across universities, exhibition halls, and automotive plants.[3]
In October 2025, Leju Robot secured $207 million in pre-IPO funding led by Greenwoods Asset Management, earmarked for mass production and technological advancement of the Kuavo robot platform.[4]
In November 2025, the Kuavo humanoid robot made history as a special torchbearer during the torch relay for China's 15th National Games in Shenzhen, becoming one of the first humanoid robots to carry an Olympic-style torch at a major national sporting event.[5]
The Kuavo series is Leju's flagship lineup of humanoid robots. The product range includes several models:
| Model | Description | Key Features |
|---|---|---|
| [[Kuavo]] 4Pro | General-purpose humanoid robot | Full-size bipedal platform for research and industry |
| [[Kuavo-5]] | Open-scale humanoid robot platform | Open platform for embodied AI development |
| Kuavo-5W | Wheeled variant of Kuavo-5 | Combines humanoid upper body with wheeled base |
| [[Kuavo-MY]] | Compact humanoid robot | 1.4 m tall, 40+ degrees of freedom |
| Specification | Details |
|---|---|
| Joint Torque | Up to 360 Nm peak |
| Rated Speed | Up to 150 rpm |
| Walking Speed | 4.6 km/h omnidirectional |
| Operating System | KaihongOS (based on [[OpenHarmony]]) |
| Locomotion | Bipedal walking, obstacle avoidance, stair climbing, jumping |
| Price (Kuavo-5) | $38,000 |
The Kuavo platform supports imitation learning and large-model AI integration, running on [[Huawei]]'s KaihongOS (based on [[OpenHarmony]]). It was the first humanoid robot to operate on the [[HarmonyOS]] ecosystem.[6]
Leju also manufactures educational programming robots under the Pando series and smaller biped robots under the Roban2 brand, targeting the educational and consumer markets.
Leju Robotics holds independent intellectual property in both hardware and control systems. The company's robots feature high-torque joint actuators rated at 360 Nm, enabling dynamic movements such as jumping (up to 20 cm vertical clearance) and omnidirectional walking across varied terrain including sand, grass, and obstacles.
The Kuavo platform integrates with [[Huawei]]'s Pangu embodied large model, which was demonstrated at the Huawei Developer Conference 2024 (HDC2024). This integration enables advanced perception, planning, and autonomous task execution.[7]
Leju's robots serve multiple sectors:
Leju Robotics has established strategic partnerships with several organizations, including Huawei for integration with the Pangu embodied large model, the Hengtong manufacturing center for industrial applications, and the city of Hefei for deployment in industrial scenarios.
In October 2025, Leju Robot closed a $207 million pre-IPO funding round led by Greenwoods Asset Management. The funds were designated for scaling mass production of the Kuavo robot and furthering technological development. This round valued the company as one of the leading humanoid robot startups in China.[4]
