Bridging the Gap Between Analog and Digital Factory Automation Through Integrated Valves

Digital innovations in hydraulic components, such as digitally enhanced high-response directional valves, are moving the needle for machine builders and raising performance standards for machine builders. As hydraulic systems evolve, smart technology is enabling deeper connectivity for more productive machines. Read on to learn more.

Soft Robots That Can Walk on Water

Imagine a tiny robot, no bigger than a leaf, gliding across a pond’s surface like a water strider. One day, devices like this could track pollutants, collect water samples, or scout flooded areas too risky for people. Baoxing Xu, Professor of Mechanical and Aerospace Engineering at the University of Virginia’s School of Engineering and Applied Science, is pioneering a way to build them. Read on to learn more.

Meet PASE: The Pneumatically Actuated Soft Elbow Exoskeleton

For workers whose jobs involve hours of lifting and repetitive motion, even small innovations can make a big difference in preventing future musculoskeletal disorders. That’s why engineers at The University of Texas at Arlington have developed PASE (Pneumatically Actuated Soft Elbow Exoskeleton), a soft robotic exoskeleton that lightens the load — literally — by reducing strain on the arm and elbow. Read on to learn more.

Baby Turtles Inspire a New Swimmer Bot

A team of roboticists at the University of California San Diego has developed a robot that can swim under the sand and dig itself out too, thanks to two front limbs that mimic the oversized flippers of turtle hatchlings. Read on to learn more about it.

Programmable Lego-Like Material Emulates Life’s Flexibility

Mechanical engineers at Duke University have demonstrated a proof-of-concept method for programming mechanical properties into solid Lego-like building blocks. By controlling the...

Engineers Find New Ways to Connect Concrete Pieces for More Resilient Buildings

Researchers have developed five new ways to securely connect large concrete pieces. These connection methods are intended for a type of material called “precast concrete,” in which parts such as beams and columns are made in a factory and assembled later at a construction site. Read on to learn more.

A Light-Powered Soft Robot That Can Carry Loads Through the Air Along Established Tracks

Researchers have created a light-powered soft robot that can carry loads through the air along established tracks, similar to cable cars or aerial trams. The soft robot operates autonomously, can climb slopes at angles of up to 80°, and can carry loads up to 12 times its weight. Read on to learn more.

Bio-Hybrid Robots Turn Food Waste into Functional Machines

Although many roboticists today turn to nature to inspire their designs, even bioinspired robots are usually fabricated from non-biological materials like metal, plastic, and...

At-Home Robotic Rehabilitation

Two former college roommates have commercialized their robotic knee brace for extending the reach of physical therapists through telehealth.

How Do Hydraulic Brakes Work?

If you’ve ridden in a modern car, bus, truck, aircraft, or even on certain bicycles, you’ve used hydraulic brakes. You most certainly have used them, but do you know how they work? Find out with this quiz.

The Mechanics Behind Motion: Exploring Planetary Servo Gearboxes

While growing up, many of us were fascinated by watching gears turning, whether in bicycles, clocks or garbage trucks packing trash on the old rear-load machines. Today, gearing systems play a crucial role in machinery, transmitting power efficiently and reliably across a wide range of applications. Read on to learn more.

Robotic System for Assembly and Maintenance of Lightweight Reconfigurable Structures

Missions to the moon and other planets will require large-scale infrastructure that would benefit from autonomous assembly by robots without on-site human intervention. NASA Ames Research Center has developed a novel and efficient mobile bipedal robot system to construct low-mass, high precision, and largescale infrastructure. Read on to learn more.

This Self-Powered Device Can Detect Toxic Amines in Water

Researchers have built a self-powered device that detects toxic amines in water using electrochemiluminescence (ECL).

Knitting Machine Makes Solid 3D Objects

A new prototype of a knitting machine creates solid, knitted shapes, adding stitches in any direction — forward, backward, and diagonal — so users can construct a wide variety of shapes and add...

The Hidden Heroes of Hydrogen Flight: Sealing and Materials
