I am Stella Qian. The Leju KUAVO is the only humanoid I have tested that runs on HarmonyOS. Here is what that means, and whether it matters for your deployment.
What is the Leju KUAVO?
Leju Robot (乐聚机器人) is based in Shenzhen. KUAVO is their full-size bipedal humanoid, built with Huawei’s HarmonyOS operating system and Pangu AI as the reasoning model. In 2025, Leju reported 12x year-over-year production growth, the fastest scaling of any bipedal humanoid manufacturer in China. The Huawei partnership is central to their positioning: Pangu is a large multimodal model and HarmonyOS is designed for connected device environments.
Specifications
- Height: 165 cm
- Weight: 55 kg
- Degrees of freedom: 32
- Payload: 5 kg per arm
- Speed: up to 1.5 m/s
- Battery: 2.5 hours
- OS: HarmonyOS (Huawei)
- AI model: Pangu (Huawei)
- Price: from $50,000
Advantages
HarmonyOS integration. In Chinese factory environments where Huawei equipment is already deployed, KUAVO connects to the existing device network without custom integration work. This reduces setup time and IT cost for Huawei-heavy facilities.
Pangu AI model. Pangu is a multimodal model that handles vision, language, and sensor data in one system. For tasks that require the robot to read labels, respond to instructions, and adapt to changing object positions in one workflow, Pangu gives KUAVO a real advantage over single-modal systems.
Bipedal with 32 DOF. Unlike the AgiBot G2 and Galbot G1, the KUAVO walks on two legs. It can handle stairs, ramps, and uneven terrain. 32 DOF gives it enough articulation for most industrial manipulation tasks.
12x production growth. A company that scaled 12x in one year has a functioning supply chain and a real customer base. This reduces the risk that your supplier disappears or delays parts.
Disadvantages
HarmonyOS dependency outside China. HarmonyOS is not widely adopted outside the Chinese market. If you are deploying in Europe, North America, or Southeast Asia with non-Huawei infrastructure, the integration advantage disappears and may become a compatibility issue.
Closed AI model. Pangu is proprietary. You cannot access the weights or fine-tune for custom tasks without going through Huawei and Leju. This limits flexibility for teams that want to build on the model directly.
Less community than Unitree. Leju does not have an open-source developer community. If you get stuck on a custom task, you rely on official support rather than a forum or GitHub.
Trade restrictions risk. Because KUAVO depends on Huawei technology, buyers outside China need to check current trade compliance rules before purchasing. This may limit deployment options in some markets.
My verdict
The Leju KUAVO is the best choice for Chinese manufacturers that already use Huawei infrastructure and want a bipedal humanoid with strong AI integration. The Pangu model and HarmonyOS connectivity are genuine advantages in that context.
For international buyers or teams that need an open platform, the Unitree G1 is a better fit. For pure manipulation tasks, the Galbot G1 delivers more DOF at a similar price.
