Engineers develop hybrid robot that balances strength and flexibility—and can screw in a lightbulb

How many robots does it take to screw in a lightbulb? The answer is more complicated than you might think. New research from Northeastern University upends the riddle by making a robot that is both flexible and sensitive enough to handle the lightbulb, and strong enough to apply the necessary torque.

“What we found is that by thinking about the bodies of robots and how we can make new materials for them, we can actually make a robot that has the benefits of both rigid and soft robots,” says Jeffrey Lipton, assistant professor of mechanical and industrial engineering at Northeastern.

“It’s flexible...

An international team led by researchers from Nanyang Technological University, Singapore (NTU Singapore) has developed a universal connector to assemble stretchable devices simply and quickly, in a “Lego-like” manner.

Stretchable devices including soft robots and wearable healthcare devices are assembled using several different modules with different material characteristics—some soft, some rigid, and some encapsulated.

However, the commercial pastes (glue), currently used to connect the modules often either fail to transmit mechanical and electrical signals reliably when deformed or break eas...

Engineers discover new process for Synthetic Material Growth, enabling Soft Robots that Grow like Plants

University of Minnesota Twin Cities researchers have developed a plant-inspired extrusion process that allows soft robots to build their own solid bodies from liquid to navigate hard-to-reach places and complicated terrain.

Soft robots can navigate hard-to-reach places like pipes or inside the human body. An interdisciplinary team of University of Minnesota Twin Cities scientists and engineers has developed a first-of-its-kind, plant-inspired extrusion process that enables synthetic material growth. The new approach will allow researchers to build better soft robots that can navigate hard-to-reach places, complicated terrain, and potentially areas within the human body.

The paper is published in the Proceedings of the National Academy of Sciences (PNAS).

“This is the first time t...

Mighty Morphing materials take complex shapes

Sophisticated shape-shifters for soft robots, biomedical applications. Rice University scientists have created a rubbery, shape-shifting material that morphs from one sophisticated form to another on demand.

The shapes programmed into a polymer by materials scientist Rafael Verduzco and graduate student Morgan Barnes appear in ambient conditions and melt away when heat is applied. The process also works in reverse.

The smooth operation belies a battle at the nanoscale, where liquid crystals and the elastomer in which they’re embedded fight for control...
