Odd new robot does ‘the worm’ to dance its way over sand, gravel, mud, and water

Crawling, swimming and climbing with a 3D printed wave producing robot (SAW)
If you’re searching for a unique robot concept, look no further than the new Single-Actuator Wave robot created by researchers at Israel’s Ben-Gurion University of the Negev. They’ve built a bio-inspired robot that creates forward motion via a “continuously advancing” transverse wave. To put it in less scientific terms, it’s a worm robot that moves forward by doing the worm dance.

“It turns out that the wave is a very efficient mechanism for moving on tough surfaces, such as sand, gravel, mud, rubble and many others,” Dr. David Zarrouk, who led the project, tells Digital Trends. “[Our robot] has a low center of gravity and can overcome many obstacles [more easily than comparable systems]. It can even swim, which makes it very versatile.”

While the wave motion is similar to the means by which creatures like snakes move (albeit flipped the other way around), it bears most resemblance to the locomotion method of tiny ocean organisms which propel themselves through the water using flagella.

The SAW robot is powered by a single motor that rotates a spine-like helix, embedded inside a series of 3D printed plastic links. As the chain-like links touch the ground, they rotate — thereby pushing the robot forward.

For Dr. Zarrouk what is most exciting about his creation is how easily it can scale up and down. But while it could definitely have advantages at a larger size, it’s on the smaller end of the spectrum where he thinks it could be most significant.

“The robot could be as small as just one centimeter,” he says. “At that size we think it could be a very useful tool for medicine, since it would be possible for someone to swallow it, and then for it to act as a self-propelled capsule for endoscopy or even taking biopsies. The doctor would then be able to control its movement in terms of whether it travels forward or backward — both of which it is capable of traveling in.”

So trippy and useful, huh? That’s our kind of robot!

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying
Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."
