NimbRo-OP2X
NimbRo-OP2X is an open source, largely 3D printed, adult size humanoid from the Autonomous Intelligent Systems group at the University of Bonn led by Sven Behnke. It is the third generation of the NimbRo-OP line that started in 2012 and has won multiple RoboCup Humanoid League adult size titles. Hardware designs and software are public.
We have not sat down with this one. The score below is computed from the data we hold, and the facts on this page are sourced. It is not on sale, so there is nothing to recommend.
How the score is built
Capability is what the machine physically does. Value compares it with others at a similar price, not with the whole market. Buyability asks whether you can really order one. Ecosystem is the software and community around it. Proof is what it has done in the field, which is where most humanoids score badly and should.

Europe's humanoids: who builds them and what you can order
31 of the 182 humanoids on record come from seven European countries. Three can be ordered, two have a price, and the dearest of those is $75,000 for a robot that does not walk.
Humanoid races, games and fights: what the competitions proved
Our record holds 11 competition events from 1997 to 2025 and 17 machines tied to them. Six can be ordered, three at a public price, and 13 of the 17 carry a teleoperation flag of yes or partial.
Open-source humanoids: what you can actually build
24 of the 182 humanoids on record call themselves open source. 15 publish hardware files and software, 3 name a licence, 12 can be ordered, and none of the four on preorder has any autonomy evidence yet.
