RB-Y1
A Samsung-backed Korean humanoid with roots in the DARPA Robotics Challenge era.
Rainbow Robotics traces its lineage back to KAIST's HUBO research program, one of the more academically rigorous pedigrees in this list, and Samsung has taken a significant ownership stake in the company.
RB-Y1 is reported available at $80,000–$120,000, considerably heavier than most peers at 131 kg, suggesting a build optimized for stability and payload over agility.
