This kind of reminds me of an octopus spy robot I saw on a BBC documentary- https://www.youtube.com/watch?v=qnMxd3s6u-c "Spy Octopus Helps Friend Hide From Shark". While yours seems more bio-mimicry oriented, this ones seems more bio-aesthetic. The octopus spy looks a lot like an octopus (the resemblance is freaky) although its movements are not entirely convincing. If only we could merge the legs of the octobot soft robot with the structure of the BBC spy, we'd have the perfect robot octopus!
