Octopus Inspired Robot can Grip, Move and Manipulate

Two-thirds of an octopus's neurons are in its arms, meaning each arm literally has a mind of its own. Octopus arms can untie knots, open childproof bottles, and wrap around prey of any shape or size. The hundreds of suckers that cover their arms can form strong seals even on rough surfaces underwater.

Soft Robotic Fingers Gently Grasp Deep-Sea Jellyfish

Marine biologists have adopted "soft robotic linguine fingers" as tools to conduct their undersea research. Scientists found that jellyfish held by ultra-soft robotic fingers expressed significantly fewer stress-related genes than when braced by traditional submersible grippers. Shaped like the famous noodles, this new robotic technology allows for the collection of ecological data in a gentler, less invasive manner.

Multimaterial 3D Printing Manufactures Complex Objects, Fast

A new technique called multimaterial multinozzle 3D printing uses high-speed pressure valves to achieve rapid, continuous, and seamless switching between up to eight different printing materials, enabling the creation of complex shapes in a fraction of the time currently required using printheads that range from a single nozzle to large multinozzle arrays.

Sensor Could be Used for Microrobotics, Augmented Reality, Wearables

For all our technological advances, nothing beats evolution when it comes to research and development. Take jumping spiders. These small arachnids have impressive depth perception despite their tiny brains, allowing them to accurately pounce on unsuspecting targets from several body lengths away.

Self-folding "Rollbot" paves the way for fully untethered soft robots

The majority of soft robots today rely on external power and control, keeping them tethered to off-board systems or rigged with hard components. Now, researchers have developed soft robotic systems, inspired by origami, that can move and change shape in response to external stimuli, paving the way for fully untethered soft robots.

Exosuit shows potential for wearable robots

Researchers have previously developed robotic devices for rehabilitation and other areas of life that can either assist walking or running, but no untethered portable device could efficiently do both.

Snake-inspired robot slithers even better

Bad news for ophiophobes: Researchers have developed a new and improved snake-inspired soft robot that is faster and more precise than its predecessor.

A safe, wearable soft sensor

Children born prematurely often develop neuromotor and cognitive developmental disabilities. The best way to reduce the impacts of those disabilities is to catch them early through a series of cognitive and motor tests. But accurately measuring and recording the motor functions of small children is tricky.

Robots with sticky feet

Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take over a month per engine. Many components are located deep inside the engine and cannot be inspected without taking the machine apart, adding time and costs to maintenance. This problem is not only confined to jet engines, either; many complicated, expensive machines.

A painless adhesive for bandaids

Pulling off a Band-Aid may soon get a lot less painful. Researchers have developed a new type of adhesive that can strongly adhere wet materials -- such as hydrogel and living tissue -- and be easily detached with a specific frequency of light.

Printing with sound

Harvard University researchers have developed a new printing method that uses sound waves to generate droplets from liquids with an unprecedented range of composition and viscosity. This technique could finally enable the manufacturing of many new biopharmaceuticals, cosmetics, and food and expand the possibilities of optical and conductive materials.

Gentle robotic hand for sea life

The open ocean is the largest and least explored environment on Earth, estimated to hold up to a million species that have yet to be described. However, many of those organisms are soft-bodied - like jellyfish, squid, and octopuses - and are difficult to capture for study with existing underwater tools, which all too frequently damage or destroy them. Now, a new device safely traps delicate sea creatures inside a folding polyhedral enclosure and lets them go without harm using a novel, origami-inspired design.

Robotic cockroach can explore underwater environments

In nature, cockroaches can survive underwater for up to 30 minutes. Now, a robotic cockroach can do even better. Harvard's Ambulatory Microrobot, known as HAMR, can walk on land, swim on the surface of water, and walk underwater for as long as necessary, opening up new environments for this little bot to explore.

Breakthroughs seen in artificial eye and muscle technology

Inspired by the human eye, researchers have developed an adaptive metalens that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the major contributors to blurry images: focus, astigmatism, and image shift.

Snake-inspired robot uses kirigami to move

Who needs legs? With their sleek bodies, snakes can slither up to 14 miles-per-hour, squeeze into tight space, scale trees and swim. How do they do it? It's all in the scales.
