Researchers use 3-D printer to print glass

For the first time, researchers have successfully 3-D printed chalcogenide glass, a unique material used to make optical components that operate at mid-infrared wavelengths. The ability to 3-D print this glass could make ...

Microrobots that can form into multiple types of swarming shapes

A team of researchers from the Harbin Institute of Technology in China and Michigan State University in the U.S. has developed a way to control swarming microrobots that are able to form into multiple types of shapes. In ...

'Particle robot' works as a cluster of simple units

Taking a cue from biological cells, researchers from MIT, Columbia University, and elsewhere have developed computationally simple robots that connect in large groups to move around, transport objects, and complete other ...

Adaptive locomotion of artificial microswimmers

Bacteria display remarkable plasticity by exploiting mechanics in response to locally changing physical and chemical conditions. Compliant structures usually assist their taxis behavior to navigate inside complex and structured ...

Customizing computer-aided design

MIT researchers have devised a technique that "reverse engineers" complex 3-D computer-aided design (CAD) models, making them far easier for users to customize for manufacturing and 3-D printing applications.

RFID tag arrays track body movements, shape changes

Carnegie Mellon University researchers have found ways to track body movements and detect shape changes using arrays of RFID tags. RFID-embedded clothing thus could be used to control avatars in video games—much like in ...

Growing bio-inspired shapes with hundreds of tiny robots

Hundreds of small robots can work in a team to create biology-inspired shapes without an underlying master plan, purely based on local communication and movement. To achieve this, researchers from EMBL, CRG and Bristol Robotics ...

EuMoBot: Replicating euglenoid movement in a soft robot

Swimming is a form of locomotion employed by many organisms across a wide range of scales in nature. Microorganisms with small mass that encounter dominance of viscous forces in the medium require a change in shape that does ...

An advanced snake-robot for disaster sites climbs by coiling

"Ladder Climbing with the Snake Robot" is a video that was released last year by Kyoto University's Matsuno Lab, and it is still drawing stares and shivers. Comments on the video have included "Thanks, I hate it."

Taking lithium-ion batteries to new extremes

Just like Goldilocks and her proverbial porridge, lithium-ion batteries (LIBs) perform best when the temperature range is just right—that is, neither too hot nor too cold. But this is a huge limiting factor when it comes ...

New 4-D printer could reshape the world we live in

From moon landings to mobile phones, many of the farfetched visions of science fiction have transformed into reality. In the latest example of this trend, scientists report that they have developed a powerful printer that ...
