In Search Of The Best Tail For Balance
12:15 minutes
If you have met a cat, you’ve probably at some point been amazed by how acrobatic they are. They’re able to reorient themselves effortlessly, even in midair. It turns out that a lot of that twistiness comes down to having a top-tier tail. While most reptile tails can swing only in one plane of movement, mammal tails have more joints, leading to better inertial control. That lets mammals tweak their balance better, much as holding a balance pole can help an acrobat navigate a tightrope.
In a recent study published in the Journal of the Royal Society Interface, researchers explored the biomechanics of different tails, and considered how a better tail could help build a better robot. Dr. Talia Moore, a roboticist at the University of Michigan, and Dr. Ceri Weber, a cellular and developmental biology postdoc at UC San Diego, join Host Flora Lichtman to talk tails.
