Before it can travel all the way to Saturn's moon, the team at JPL is hoping to deploy the Exobiology Extant Life Surveyor (EELS, get it?) robot in other hard-to-access locations on Earth, the Moon, and beyond. The team's aim is to create the ultimate jack-of-all-trades with a unique wheels-coming-off approach to robot building. "It has the capability to go to locations where other robots can’t go," said JPL’s Matthew Robinson, EELS project manager, in a [statement](). "Though some robots are better at one particular type of terrain or other, the idea for EELS is the ability to do it all." https://youtu.be/ifCIDT4X9AM ## Slithering Bot In a [new video](), the robot can be seen slithering across a variety of surfaces, including an iceskating rink, a snowy mountainside, and a beach. They even put it through its paces at the JPL's Mars Yard, a simulated Martian landscape. The 13-foot robot moves by rotating its ten identical segments, which are outfitted with threads that allow it to propel itself forward. These individual segments can even act as propellers, allowing EELS to explore its surroundings underwater. That's important, as JPL is hoping to have the robot eventually explore the habitable subsurface oceans of Saturn's moon Enceladus. To get to this ocean, the robot will have to snake itself through one of the many icy geysers that erupt from the moon's surface before dropping into the depths below. ## Down the Hole It will also have to do all of this entirely on its own. "Imagine a car driving autonomously, but there are no stop signs, no traffic signals, not even any roads," said the project’s autonomy lead, Rohan Thakker, in the statement. "The robot has to figure out what the road is and try to follow it." "Then it needs to go down a 100-foot drop and not fall," he added. The team is hoping to send EELS down a vertical shaft, or a crevasse, in the Canadian Rockies later this year, which will act as an analog for Enceladus' vents. It's an immense engineering challenge, especially given how little we know about the icy moon's environment. "When you’re going places where you don’t know what you’ll find, you want to send a versatile, risk-aware robot that’s prepared for uncertainty," Robinson said, "and can make decisions on its own." **More on JPL's robots:** *[NASA Shows Off Transforming Rover for Exploring Steep Cliffs on Mars]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
