Quick Answer
NimbRo-OP2X is the University of Bonn’s adult-size open humanoid platform — about 135 cm, 19 kg, 18 joints / 34 actuators, 8.0 Ah pack, 20–40 minutes of runtime in the public notes. It is a RoboCup-scale research body, priced as parts, not a 9.0 industrial score.

What it is
Bonn NimbRo’s open adult-size biped, bigger than OP3, still a competition/research machine.
What is published
A thick public card: 27 spec items, 14 references. Runtime 20–40 min is the honest limiter.
Flaws
You build and maintain it. 20–40 minutes is a match, not a shift. The stencil still compared it to Figure 02.
Real-world usefulness
High for adult-size open-source work. OP3 and Poppy are the smaller open cousins on this site.
