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.
