Leju has no official spec sheet; the 4.6 km/h walking speed is press-reported, and reported mass ranges from ~45 kg to ~63.5 kg by generation. The company delivered its 100th full-size humanoid in 2025. The year 2023 is not confirmed by a fetched source. kuavo-ros-opensource is actively pushed (Sept 2026) but has no license file, so its code is all rights reserved and sw is left undeclared.
