Although there are many insects with wings that fold down beneath covers when not in use, the earwig's wings fold the most compactly. Scientists have now copied that folding mechanism, with an eye towards using it in human technology.

As we continue to explore other planets, we're going to want to know not only what's on their surface, but also what's underneath it. That's where the Mole-bot comes in – it's a robot that autonomously tunnels its way through the ground.

It was seven years ago that we first heard about Harvard University's HAMR cockroach-inspired robot. Although the bot was already on the tiny side, its designers have now created a version that's just half its size – it's time to meet HAMR-JR.

A couple of years ago, Harvard scientists copied the structure of snake skin to create a soft-bodied robot that gripped the ground as it moved. Now, they've applied that same thinking to shoe grips that could help keep seniors from falling.

The "sea skater" is one of the few insects that lives full-time in a marine environment. Scientists are now taking a closer look at how the animal repels water, with an eye towards the development of more hydrodynamic ship hulls.

Researchers have taken inspiration from a mosquito's ability to fly and land in the dark to develop a new collision-avoidance sensory system for drones that mimics the insect's ability to use airflow to detect obstacles.

When we think of soft-bodied robots, we tend to picture things that slowly crawl like caterpillars. A new one is able to move much quicker, though, by leaping like a cheetah.

Although they're relatively large, manta rays move easily through the water, thanks to their sleek shape. Well, that form has been copied in the aptly-named Manta Ray aerial delivery drone, which recently won an international competition.

Nanofibers have found use in numerous applications, ranging from lightweight car parts to high-strength materials. Now, thanks to a new understanding of a certain group of spiders, they may soon be easier to work with.

Insects rapidly transition between walking gaits, in response to external stimuli. Scientists have now created a robot that does the same thing, utilizing an artificial neural network – the tech might ultimately find use in better prostheses.

Soft-bodied robots have numerous desirable qualities, such as the ability to squeeze through gaps. And so far, they've typically been manually assembled on a one-off basis. That could be about to change, though, thanks to a new manufacturing method.

Marine aquaculture pens have to be regularly checked for holes, plus the fish need to be inspected for parasites. And although the job is typically performed by human divers, it turns out that a robotic sea turtle may be a better choice for the task.
