Good question. I'd assumed, given that it's an IEEE website, that they were rated by members of IEEE (Institute of Electrical and Electronics Engineers). Instead, looks like it's open to anyone to rate - you can go to any individual robot's page (https://robotsguide.com/robots/spot https://robotsguide.com/robots/spot) and rate it on the three questions asked. And it seems to be a naive average of users' ratings, so the "top" robot has only 7 ratings, the second one 109 ratings, and the third has 12,510 ratings! It's likely that if they used something more reasonable like a Bayesian average, Spot and Atlas would be in the top 5, given the number of votes they have compared to the others.
