New Soft Robots Really Suck
September 1, 2017 | EPFLEstimated reading time: 1 minute

EPFL scientists have created the first functional robot powered entirely by vacuum: made up of soft building blocks, it moves by having air sucked out of them. The robot can be reconfigured to perform different tasks, like climbing vertical walls and grabbing objects.
This new robot sucks: to move, air has to be sucked out of its individual components. Inspired by muscle contraction, its individual soft components are activated (they collapse) when negative pressure (vacuum) is applied to them. The robot uses suction to grab objects or to stick to a smooth wall for climbing, so it can really achieve a wide range of tasks because of the unique properties of vacuum. The robot can be reconfigured to perform different tasks, making it highly modular and versatile, with a wide range of applications in both research and in industry. The invention is published today in Science Robotics.
“What we have is a fully functional robot which is entirely powered by vacuum, which has never been done before,” says EPFL roboticist Matt Robertson who worked on the project. “Previous work has shown individual components powered by vacuum, but never in a complete system.”
Vacuum-powered components are a recent addition to robotics – and, more importantly, they’re safe. Today, most actuators on the market are activated by applying positive pressure, i.e. by injecting air into their components. But containing positive pressure requires stiff high-pressure pneumatics, which also pose a safety threat: in extreme situations, they can explode. By comparison, vacuum-powered actuators are safe, soft, and simple to build.
“What's more is that our soft building blocks are designed to be plug-and-play, so ultimately we can assemble several types of robots from the same basic units,” says EPFL scientists and lead researcher Jamie Paik. “They can be reconfigured to perform different tasks like crawling, gripping canisters, and climbing a vertical wall.”
A five-module robot can move like a tentacle; a four-module robot with a suction gripper can grab an object and drop it on a target; a three-module robot can crawl on the ground; a two-module robot can be equipped with suction-cup feet to climb a smooth, vertical surface, like glass. The enormous versatility of the new robots can be exploited for studying locomotion and for future applications at an industrial level.

Elementary, Mr. Watson: Why Your PCB Looks Like a Studio Apartment
08/13/2025 | John Watson -- Column: Elementary, Mr. WatsonIn November 2022, I wrote a column called "Is Your Bathroom in the Kitchen?" This piece related a bizarre real estate listing that emerged out of St. Louis that had architects scratching their heads and interior designers cringing. Nestled in the historic Central West End sat a 200-square-foot apartment that completely defied logic. It wasn't the size that raised eyebrows, it was the layout. Here's the kicker: While that's rare in real estate, it's shockingly common in PCB design.
From Factory Floor to ‘The Component Store’
07/25/2025 | Marcy LaRont, I-Connect007Daniel Beauvois began his career in PCB manufacturing 15 years ago with zero industry experience—just a willingness to learn. Daniel immersed himself in every step of circuit board production, from hanging out on the factory floor to giving plant tours. Now, as founder of The Component Store, he’s an independent sales rep known for integrity, persistence, and deep technical knowledge. In this interview, Daniel reflects on his journey, the realities of being an outside rep, and what it takes to earn—and keep—a customer’s trust in an ever-evolving electronics industry.
