Key facts

• Sources: Leju's own Kuavo 4Pro manuals on kuavo.lejurobot.com, Standard edition page (manual) and Showroom edition page (beta_manual), both fetched 2026-10-17; lejurobot.com/en (fetched 2026-10-17) lists 'KUAVO 4Pro' in its homepage carousel but has no 4Pro product page or spec table (the nearest product page, /en/products/kuavo-my, carries no figures).
• Both editions: height 1.66 m, weight 55 kg, arm length 0.79 m, walking 0.4 m/s, running 5 km/h, battery 60 V / 6 Ah, about 1 h walking endurance, at least 500 cycles, charge time 1.5 h or less. Third-party pages quote 7 km/h and '40+ DoF'; those are not on the official pages and are not used.
• DoF as the manuals count them (excluding end effectors): Standard 22 = 5 per arm + 6 per leg. Showroom 28 = 2 head + 7 per arm + 6 per leg, plus 6 DoF per dexterous hand listed separately. The base spec uses the Standard 22; the Showroom override is 28.
• battery_wh is left empty: the manuals give 60 V / 6 Ah but also show two swappable batteries (left and right bays) and do not say whether 6 Ah is per pack or total, so the capacity could be 360 or 720 Wh. max_speed_ms 1.39 is the published 5 km/h running speed converted. battery_swappable is true because the manual documents a battery-swap board. Payload is not given in either manual.
• Standard-edition upper computer is an NVIDIA Orin NX (no TOPS variant stated, so compute_tops is empty); the Showroom edition lists SWNUC12WSKI70000 instead. A wheeled-arm 4Pro variant has its own manual page and is not covered here.
• Price: Leju publishes none. Press reports of earlier Kuavo generations (about 600,000 CNY in 2024) concern a different model and are not recorded as 4Pro prices. Image shows the Showroom edition (with hands), while the base specs are Standard; it is the official render from Leju's manual site, cropped to the robot and padded on white.
• Status is 'limited': only the user manuals document the Standard and Showroom editions; lejurobot.com/en lists 'KUAVO 4Pro' in a carousel with no product page, price or availability statement, so year_available is empty.
