> **[A robotic tail for humans inspired by seahorses - CNN Video](https://www.cnn.com/videos/style/2019/08/15/japan-robotic-tail-balance-keio-university-kk-lon-orig.cnn)** > > A wearable robotic tail was designed at Keio University in Tokyo that may help humans correct their balance the same way animals do. The first question is “Why do that?” Humans already have a system for providing balance. We’ve got a butt. Humans are, AFAIK, the only bipedal creatures without significant horizontal extensions (like ducks, geese, and other birds) who maintain their upright balance for long periods of time without using a tail. we have outrageously large and strong muscles to keep us upright, chiefly the _gluteus maximus_. We try to characterize ourselves as The Animal that Thinks or The Animal that Laughs, but in reality, Man is the Animal With a Butt. Clearly one reason is That They Can. And I have to admit that it is pretty cool – a computer-controlled, pneumatically activated articulated tail to maintain balance. The “inspired by a seahorse” part is obviously about the structure – seahorses don’t need a tail to maintain balance. The report says that it’s for people who need help balancing – the injured, elderly, and infirm. And this is a Noble Cause, but I imagine people getting calls from their older relatives for help with these: “Bob, grandma had to take off her tail to use the bathroom, and can’t get it back on again. Can you go over and help her put it back on?” I can also imagine older couples out walking together, hand in hand, and perhaps, tail entwined with tail. ---

I am stunned it doesn’t look more like a tentacle. I understand it’s primarily for balance, but wouldn’t it be cool if you could also control it to manipulate your center of gravity in anticipation of a stunning acrobatic move, work as a prehensile fifth limb, or to communicate. ---

I am not going to Google “Japanese Tail.” ---

OK, I just Googled Japanese Tail. The only hits showing up are the device in the OP, more entries than you might imagine on how to translate Tail into Japanese, and then some recipes for preparing yellowtail. ---

> [@CalMeacham](#): > > . . . The report says that it’s for people who need help balancing – the injured, elderly, and infirm. . . Neat idea but I hope it’s lightweight, really light. In my experience (caring for zillions of the “elderly and infirm”) general frailty and loss of muscle strength often exceeds imbalance itself as the cause of falls and limited mobility (let alone the strokes, arthritis, neuropathy, and visual and cognitive impairment). ---

The very first insta-thought I had when I read the title of this thread was: man… as the years go by, William Gibson looks more and more prescient. ---

I would wonder whether this would give gymnasts a greater ability or dampen it. Probably the latter, so long as it wasn’t under conscious control. But maybe the former if it was. ---

If the Tail were primarily used by old or motion-impaired folks, it would rapidly cease to be considered in any way cool.
