Fast Charging of Electric Cars Without Cables

In a cooperative project, Empa researchers investigated inductive charging of electric cars. This is not only similarly efficient to cable-based charging but could also simplify the integration...

Integrating Large Language Models into Autonomous Vehicles

Imagine simply telling your vehicle, “I’m in a hurry,” and it automatically takes you on the most efficient route to where you need to be. Purdue University engineers have found that an autonomous vehicle (AV) can do this with the help of ChatGPT or other chatbots made possible by artificial intelligence algorithms called large language models.

What Robots Can Learn from Sea Stars

Sea stars are creatures whose movements involve the coordination of hundreds of tiny tube feet to navigate complex environments — despite the lack of a central brain. In other words, it’s as though...

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.

High-Voltage Switch Innovation for Electric Power Systems

Pinggao Group focuses on the development and production of high-voltage and ultra-high-voltage electrical equipment. Different teams at the company use simulation to explore in depth the factors that affect the performance of high-voltage switches as well as to optimize switch designs and predict the operational status of equipment.

Bringing and keeping robotaxis on the road requires a village.

World’s Smallest Programmable, Autonomous Robots

Researchers at the University of Pennsylvania and University of Michigan have created the world’s smallest fully programmable, autonomous robots: microscopic swimming machines that can...

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.

Advances in Fiber Laser Welding for E-Mobility Manufacturing

As electric vehicle designs change and production targets grow even more aggressive, advanced laser welding technologies have continued to evolve to help manufacturers be more efficient and stay competitive. Read on to learn more about it.

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).
