K2 Bumblebee
A full-size Chinese humanoid in mass production, priced in the middle of the pack.
Kepler is a less internationally recognized name than Unitree or UBTECH, but K2 Bumblebee is reported to be in mass production at adult scale with 52 degrees of freedom — a genuine competitor in the same weight class as Boston Dynamics' Atlas or UBTECH's Walker S2.
Reported pricing around $34,000 sits between Unitree's aggressive low end and the unpublished, likely much higher pricing of the top Western platforms.
