# Strange Modular Robots Are Writhing Across Landscapes

The future of robotics may not lie in the clunky androids we've been seeing [so many of lately](<https://futurism.com/artificial-intelligence/surreal-footage-melania-trump-white-house-robot>), but instead in strange, arachnoid conglomerations of sticks that writhe their way across landscapes.

These so-called "metamachines" kind of look like if you made giant caltrops out of Magnetix and then zapped them with the gift of movement. They might sound cute, except that their creators say that their AI algorithm-inspired designs lets them keep persevering even after losing parts of themselves, like a limb that gets hacked off from a horror movie's killer robot.

In [footage](<https://x.com/Reuters/status/2037514985342181808>) of the metamachine's exploits, a researcher bludgeons one with a heavy stick that cuts off its rear half. This would immobilize or maybe even brick a robodog or a humanoid machine. Even so, the thrashing robot continues to crawl forward, unbothered.

Their hardy nature is thanks to their modular design, wherein each of the robot's leggy protrusions, each half a meter long, are themselves their own robots, connecting to each other with spherical elbow joints. In theory, this makes them incredibly versatile, capable of reconfiguring their forms to navigate tricky environments.

"We're making robots that are made of robots, which is why I call them metamachines," Sam Kriegman, a roboticist at Northwestern University and coauthor of a [new study](<https://www.pnas.org/doi/10.1073/pnas.2519129123>) published in the *Proceedings of the National Academy of Sciences*, [told *Reuters* in an interview](<https://www.reuters.com/video/watch/idRW774026032026RP1/?chan=technology>).

"If one part of the body is damaged or lost to injury, the rest of the body is fine," Kriegman added. "It survives. It continues to function."

The researchers liken their design to a new "species" of machines, with chameleon-esque adaptability. Continuing the animal analogies, a [university release](<https://www.mccormick.northwestern.edu/news/articles/2026/03/evolved-robots-are-born-to-run-and-refuse-to-die/>) characterizes the metamachines as able to "undulate like seals, bound like lizards, or spring like kangaroos." (Outwardly, the appearance is more like an abortive spider.) And besting many beetles, the robots can "instinctively" flip themselves upright if they're turned over, and even show off with acrobatics like pirouetting in the air.

"We really wanted to create robots that were more resilient and that could evolve," Kriegman said. "We evolved these robots to move themselves through the world with a little bit of athleticism, so more athletic than any other modular robot has been on land. More athletic than any other evolved robot has been."

It's not the only research exploring modular robots. A team from Columbia University developed a prototype robot platform called a "[Truss Link](<https://futurism.com/prototype-robot-cannabalize-other-robots>)" that can similarly combine with each other to form a larger unit capable of crawling and even climbing up obstacles. At NASA, engineers have designed a [snake-like robot](<https://futurism.com/the-byte/nasa-snake-robot-saturn-moon>) to plunge into the vents on the surface of Saturn's moon Enceladus. These unorthodox designs suggests that there may be useful alternatives out there to the typical bipedal and quadrupedal designs that dominate the public's imagination.

## Author
At Futurism, my work has often centered on bringing a sense of clarity and insight to complex topics ranging from the regulation of emerging technologies to the esoteric ideologies of Silicon Valley executives, while striving not to lose the poetic sense of awe inspired by often-obscure fields like astrophysics and quantum computing. I broke the story of CNET using AI to produce articles that turned out to be riddled with factual errors and plagiarism — a dam-breaking inflection point, as I've reported, that's inspired copycats and endless discourse while beguiling stakeholders ranging from tech giants to purveyors of spam around the web. My work at Futurism has been cited by publications including CBS News, the Los Angeles Times, Vice, Gizmodo, Engadget, the Verge, and Vanity Fair. I grew up in locales ranging from India to China, and now live in the exotic suburbs of Virginia. In my free time, I'm an avid reader of weird sci-fi literature, an aficionado of East Asian cinema, and, regrettably, a relapsed gamer. Allegedly, I’m working on a debut novel, currently untitled.
