A tiny robot that can walk on the surface of the water. Interesting. But, please, check Fig 5. What is this? Is this a censored picture of two water striders, caught in the act..? Notice the euphemism in the text “during rowing or to support the weight of a companion”…oh, yes…duh, rowing! What about the stripes covering the parts, and the shameful faces, it’s like they say “yes, we are very famous porn water striders stars, but we needed the money, and here we are, posing for this supposedly scientific site…”? Do they think we can’t notice? How many more censorship attacks from the government are we going to support? Aing?
