An Ancient Stingray Lookalike Insres Underwater Soft Robotics
Fossil animals are informing the field of soft robotics, and applications are abundant.
Around 500 million years ago, a strange ancestor of the modern sea star, sea urchin, and sand dollar swam above the Paleozoic seafloor. Classified as a pleurocystitid, the animal resembled an armored stingray in its appearance, armed with what looked like a set of swooping antennae.
One of the first of its phylum to move around autonomously, its segmented tail swept from side-to-side to swim forward. Robotics researcher Richard Desatnik and colleagues identified the creature’s method of movement in 2023, after constructing robot replicas of the creature to simulate its swim.
Published in PNAS in November 2023 and set to appear in a presentation at the 68th Biophysical Society Annual Meeting in February 2024, the researchers’ work testifies to the wide variety of applications of ancient-animal-inspired robotics.

Never mind soft robotics … that mamy-jammer was ARMORED … now that’s right up my alley! Built to take on the enemy!

No surprise, Mother Nature is always adapting her subjects to more efficient forms of themselves.

Mother Nature Will Always Win... No Matter How Long It Takes.
And She'll Be HERE, Long After The Human Race Is GONE.

at the very least, that life on Earth very likely goes back a very long time: to when Earth was less than 10% its current age. Most have assumed this implies that life arose very early on in Earth’s history, perhaps even during its most primordial stages. But there’s another possibility that’s even more fascinating: perhaps the life that we find on Earth didn’t originate on Earth, but was formed prior to it.
Perhaps, once Earth formed, there were extraordinarily primitive organisms that came to Earth, found they could survive and reproduce here, and that’s how life began on our planet. As wacky and wild as this idea sounds, it’s a hypothesis that we not only cannot rule out, but one that has a wide variety of indirect support that bolsters its plausibility.
The idea that Earth was “born” with life already on it really, truly could be the case. Here’s why this is a scientifically interesting scenario to explore.
