📌 MAROKO133 Eksklusif ai: Korea Tests Ultra-Rugged Robot to Explore the Moon’s Mys

If humans finally colonize the Moon, lunar caves formed from primeval volcanic activity could provide shelter from cosmic radiation and extreme temperatures. But how does one go about safely exploring these uncharted caves before they venture in?

Enter a team of scientists from South Korea who have built a simple rover prototype that can traverse rough terrain. What’s truly special about this robot are its sturdy wheels, made of flexible metal strips woven together into a helix-like pattern that give it the ability to expand and contract like a piece of kinetic art.

“Experimental results show successful traversal of 200-millimeter [7.8 inches] obstacles, stable mobility on rocky and lunar soil simulant surfaces, and resilience to drop impacts simulating a 100-meter [328 feet] descent under lunar gravity,” write the scientists in a new paper published in the journal Science Robotics.

Because it can grow from nine to 19.6 inches in diameter, a rover with these wheels is able to distribute weight more evenly along its body. The result is a bot robust enough to navigate tricky cavern landscapes, along with the ability to fit into tight spaces in its smallest configuration. Other robots have used hinges or “origami-inspired folds” which can be vulnerable to lunar surface hazards, according to the paper.

The scientists demonstrated the wheel’s robustness and ability to travel around or over obstacles by having the rover explore a real cave here on Earth. They also used a drone to drop it in the air, and blasted it with fire and cold. The metal in the wheel itself is made from light weight carbon steel strips, making them tough but elastic.

“Consequently, the wheel could absorb impacts and navigate uneven terrain while remaining robust under extreme lunar conditions,” the paper reads.

For a future mission to the Moon, the team envisions a large rover carrying multiple smaller rovers with these special wheels and deploying them at the opening of a lunar pit.

“Although the explorers remain compact when stowed, the large diameter of the deployable wheels is expected to increase the ground contact area, thereby improving traction on thick dust and uneven slopes,” the paper reads. “This capability would allow the explorers to navigate challenging pit entrance terrain safely.”

The large rover would then directly drop these smaller rovers inside the lunar pit leading to a cave, with the “wheels’ elasticity and impact capacity” serving as shock absorbers.

“The results highlighted the deployable wheel’s ability to combine adaptability, durability, and operational efficiency, making it a promising solution for diverse and challenging mission scenarios,” the paper reads.

As generative AI seeps into virtually every aspect of our daily lives through jobs, entertainment, and even food, you gotta wonder: is anyone not on board with the AI takeover?

Apparently not. Former McKinsey analyst turned Dartmouth University professor Scott Anthony told Fortune that one of the feelings he’s seeing more and more among college students isn’t excitement for the AI future, but utter terror.

“One of the things that really surprises me consistently is how scared our students are of using it,” Anthony said of large language models (LLMs). The fear isn’t just over typical academic issues like cheating, he told Fortune, but about losing their critical thinking skills to the machine — they’re “scared full stop.”

“There’s something about AI where people, I think, worry that they’ll lose their humanity if they lean too much into it,” Anthony explained. “History teaches me very clearly that in the middle of a change like this, it’s very messy.”

The Dartmouth prof contrasted his student’s anxieties to those of his fellow tenured professors, who are typically eager to try out the latest LLM software. It’s not hard to see why this is the case — with a cushy gig at one of the nation’s elite universities, Dartmouth faculty are free from the economic horror story that is the AI boom. For students entering today’s job market, the future looks far less secure.

But even beyond career viability, students’ anxieties that AI use could make them dumber aren’t unfounded. One headline-inducing study from MIT earlier this summer split participants into three groups to compete tasks like writing essays: one which used LLMs, one which used common search engines, and one “brain only group.”

Compared to the other groups, the researchers found that the LLM group had an easier time writing their essays, though this “came at a cognitive cost, diminishing users’ inclination to critically evaluate the LLM’s output or ‘opinions,’” the paper explained. Basically, the group using AI gravitated toward an echo chamber moderated by AI, not by their own brains.

On top of that, participants in the brain-only group reported “higher satisfaction” with their essays, and “demonstrated higher brain connectivity” than the others.

In other words, it seems Gen Z has a right to be scared.
