Is It a Material? Is It a Robot? It's Both!

Engineers have created a type of material that can expand, assume new shapes, move, and follow electromagnetic commands like a remotely controlled robot even though it lacks any motor or internal gears.

Engineering the EL9: Electra's Ultra Short Hybrid-Electric Aircraft

Marc Allen, CEO of Electra, is the guest on this episode of the Aerospace & Defense Technology podcast.

RoboBee Comes in for a Landing

The Harvard RoboBee has long shown it can fly, dive, and hover like a real insect. But what good is the miracle of flight without a safe way to land? A storied engineering achievement by the Harvard...

Engineering a Robot That Can Jump 10 Feet High — Without Legs

Inspired by the movements of a tiny parasitic worm, Georgia Tech engineers have created a 5-inch soft robot that can jump as high as a basketball hoop. Their device, a silicone...

New Wearable Tech Simulates Realistic Touch

When it comes to haptic feedback, most technologies are limited to simple vibrations. But our skin is loaded with tiny sensors that detect pressure, vibration, stretching, and more. Now,...

New High-Speed Microscale 3D-Printing Technique

Researchers at Stanford University have introduced a more efficient processing technique that can print up to 1 million highly detailed and customizable microscale particles a day. Read on to learn more about it.

Gear Motors Help Put the Squeeze on Materials Requiring Dewatering

The applications that require dewatering are too numerous to list in their entirety. Dewatering is a process that — as its name suggests — separates fluids from solids, often converting what would otherwise go down the drain or end up in a landfill into saleable products. Read on to learn more about it and how gear motors come into play.

MIT Engineers Develop a Fully 3D-Printed Electrospray Engine

An electrospray engine applies an electric field to a conductive liquid, generating a high-speed jet of tiny droplets that can propel a spacecraft. These miniature engines are...

When Mushrooms Control Robots

In creating a pair of new robots, Cornell researchers cultivated an unlikely component: fungal mycelia. By harnessing mycelia’s innate electrical signals, the researchers discovered a new way of controlling “biohybrid” robots that can potentially react to their environment better than their purely synthetic counterparts. Read on to learn more.

Insect Cyborgs: Toward Precision Movement

In a recent study published in the journal eLife, an international research group has studied the relationship between electrical stimulation in stick insects’ leg muscles and the resultant torque (the twisting force that makes the leg move). Read on to learn what they found.

Can DNA-Nanoparticle Motors Get Up To Speed With Motor Proteins?

DNA-nanoparticle motors are exactly as they sound — tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially,...

Can Self-Driving Cars Navigate Roundabouts?
