Product overview
About Leju KUAVO 4 Pro
KUAVO 4 Pro is a full-size biped humanoid from Leju Robotics in Shenzhen. Leju's current Standard manual specifies a height of 166 cm, a weight of 55 kg and 22 body degrees of freedom excluding the end effector. The MaxB manual specifies 28 body DoF and two six-DoF tactile hands, for 40 total, which reconciles the 40-DoF figure in Leju's 2026 IPO filing.
Both current manuals give a running speed of 5 km/h, a walking speed of 0.4 m/s, and a 60 V, 6 Ah swappable battery: 0.36 kWh, one hour of walking endurance and no more than 1.5 hours to charge. The filing describes a 40-DoF product configuration with at least two hours per battery, a 15 kg whole-body payload and a 5 kg single-arm payload, so endurance varies by configuration.
A research edition was released in October 2024. A June 2026 arXiv paper reports real-robot experiments on a KUAVO 4 Pro, and Leju publishes a ROS/Python SDK. The filing reports 577 KUAVO-series units sold in 2025. No price or order page for the 4 Pro appears in the sources reviewed.
