Sub-millimeter-sized robots can sense, 'think' and act on their own
Robots small enough to travel autonomously through the human body to repair damaged sites may seem the stuff of science fiction dreams. But this vision of surgery on a microscale is a step closer to reality, with news that researchers from the…

It is rocket science: New method to more rapidly evaluate heat shields
From the tragedy of the space shuttle Columbia disaster in 2003 to the now-routine return of commercial spacecraft, heat shields—formally called thermal protection systems—are critical for protecting vehicles from the intense heat and…

Transparent ceramic could boost internet speeds and cut energy use
A new class of ceramics are not only transparent, but they can control light with exceptional efficiency—better than any theories predicted. Now, an advanced theory put forth by researcher at Penn State may explain why this material is so good…

How iRobot lost its way home
There’s something painfully American about the arc of iRobot, the company that taught your vacuum to navigate around the furniture. Founded in 1990 in Bedford, Massachusetts by MIT roboticist Rodney Brooks and his former students Colin Angle…

Weekly Robotics #340
Last week, I attended the first Paris HW Meetup. It was great to come back to France, even for a little while, and learn what people are up to at Hugging Fave, UMA, Stanley Robotics, and Gobano Robotics. It was also my pleasure to present…

AI finds a hidden stress signal inside routine CT scans
Researchers have used a deep learning artificial intelligence model to identify what they describe as the first biomarker of chronic stress that can be directly seen on standard medical images. The findings are being presented next week at the…

Beyond mimicry: Fiber-type artificial muscles outperform biological muscles
Biological muscles act as flexible actuators, generating force naturally and with an impressive range of motion. Unsurprisingly, scientists and engineers have been striving to build artificial muscles that mimic these abilities. A new review…

More brines could be mined for lithium with counterintuitive method
Lithium could be selectively extracted from “low quality” brines using a surprising mechanism discovered at the University of Michigan. The technology could help make brine lakes rich in magnesium a more sustainable source of lithium for…
