WHICHBOT SCORE	7 / 10	7.5 / 10
OUR TAKE	The first full-size humanoid built to be looked at rather than put to work. Fabric-wrapped, 27 degrees of freedom, and a motion stack that does runway walks and full splits. It will not do a single chore.	China’s answer to Optimus — an EV maker converting its car-factory muscle into humanoids, starting on its own production lines.

Detailed comparison: Luna vs Iron

Luna scores 7/10 in our independent evaluation; Iron scores 7.5/10. That 0.5-point gap is real but not decisive — Luna may still be the right fit depending on your use case.

Luna is best for: Malls, theme parks, trade shows and brand activations that need a crowd to stop walking. Iron is best for: Tracking whether the Tesla playbook works twice — this time from Guangzhou.

Our scoring weighs five factors: autonomous capability, independent verification (third-party evidence scores higher than manufacturer claims), commercial deployment scale, price-to-capability ratio, and real-world availability today. Neither robot here is scored on marketing alone. Luna and Iron are both worth evaluating — the right call depends on which robot's documented strengths match your actual workflow.

WHICHBOT VERDICT
