The cockroach is a deeply unlovable member of the animal kingdom. Not only are these nocturnal pests nearly indestructible, they're also known to spread diseases like dysentery, plague, and leprosy. Anyone who has lived in a cockroach-infested apartment knows how hard they can be to kill.
But as this video from Science shows, cockroaches' sheer tenacity is why they're worth studying:
The cockroach's back shell is both rigid and flexible — it can compress down to a third of its height and can withstand up to 900 times the cockroach's bodyweight. The flexibility allows the insect to fit through just about every crack and crevice in your home.
The researchers wanted to see if they could replicate the cockroach's ability in a robot. They managed to build such a bot that, like a roach, can be compressed to half its size and can crawl under very tight space. Their findings were recently published in the Proceedings of the National Academy of Sciences.
This robot could one day be used to locate victims in collapsed homes or other tightly confined spaces. It's called CRAM (compressible robot with articulated mechanisms), and I'd much rather live in an apartment filled with them.
Will you support Vox’s explanatory journalism?
Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:
First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.
Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.
So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)
If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
