Kuavo (also spelled Kuafu, after a figure in Chinese mythology) is the flagship full-size humanoid robot from Leju Robotics, a Shenzhen-based company founded in 2016 that spun out of the Harbin Institute of Technology. Leju is a long-standing player in Chinese robotics — its educational robots predate the current humanoid boom by years. Kuavo was unveiled in December 2023 as a high-dynamic humanoid notable for being among the first to run on Huawei's HarmonyOS, paired with Huawei's Pangu AI model.
Price Range
A robotics aggregator lists an estimate around $38,000 for Kuavo; treat this as indicative. Leju has raised over $200 million in pre-IPO funding to scale humanoid production, and by 2025 had delivered its 100th full-size humanoid; Kuavo has been tested at NIO's smart factory.

| Traction | 100th full-size humanoid delivered (2025); NIO factory testing |
Full Specifications
Figures reflect the Kuavo line (Leju has iterated through Kuavo generations to Kuavo 3.0 / Kuavo-MY and the modular Kuavo 5).
| Spec | Value (reported) |
|---|---|
| Height | ~1.70 m |
| Walking speed | ~4.6 km/h (omnidirectional; on sand, grass, factory floors) |
| Jump | ~20 cm vertical |
| Joint torque | ~360 N·m joints |
| Arm DOF | ~14 (arms); waist and high-torque joints across the body |
| Runtime | 8+ hours per charge (built for continuous labor) |
| OS / AI | Huawei HarmonyOS / KaihongOS (OpenHarmony-based); Huawei Pangu AI model |
| Domestic content | 90%+ of components domestically produced |
| Modular variant | Kuavo 5 switches between bipedal and wheeled locomotion |
Model Breakdown
Kuavo is Leju's general-purpose full-size humanoid line. It has iterated through several generations — Kuavo-MY (a commercial open-platform/service variant), Kuavo 3.0, and the modular Kuavo 5 / Kuavo 5-W (switchable legged/wheeled locomotion). Leju's broader catalog also includes the AELOS educational robots (covered below), the ROBAN medium biped, and the PANDO miniature humanoids.
Buyer's Guide: What to Know
Kuavo is a continuous-labor industrial humanoid. An 8+ hour battery and omnidirectional terrain walking point to sustained factory and logistics use.
The Huawei software tie-in is distinctive. Running on HarmonyOS/KaihongOS with the Pangu AI model differentiates Kuavo within China's humanoid ecosystem.
Domestic supply chain is a deliberate strength. With 90%+ domestic components, Leju emphasizes supply-chain resilience and cost control.
Consider the modular Kuavo 5. If you need switchable legged/wheeled mobility, the newer Kuavo 5 is the relevant variant; the base Kuavo is the bipedal foundation.
Kuavo vs Similar Robots
- Kuavo vs UBTECH Walker S: Both are Chinese industrial humanoids tested at NIO; Kuavo's distinguishing feature is its Huawei software stack.
- Kuavo vs Kepler Forerunner K2: Both emphasize long battery life for industrial shifts; both are aggressively priced.
- Kuavo vs Leju Aelos: Same maker — Kuavo is the full-size industrial humanoid; Aelos is the small educational robot.
