Octopus inspires new suction mechanism for robots

Suction cup grasping a stone. Credit: University of Bristol A new robotic suction cup that can grasp rough, curved and heavy stone, has been developed by scientists at the University of Bristol. The team, based at Bristol Robotics Laboratory, studied the structures of octopus biological suckers, which have superb adaptive suction abilities enabling them to […]

An ink for 3D-printing flexible devices without mechanical joints

The lab’s DNGE prototype “finger” with rigid “bones” surrounded by flexible “flesh.” Credit: Adrian Alberola EPFL researchers are targeting the next generation of soft actuators and robots with an elastomer-based ink for 3D printing objects with locally changing mechanical properties, eliminating the need for cumbersome mechanical joints. For engineers working on soft robotics or wearable […]

Are surgical robots better for surgery?

Surgical robots are the most common type of medical robot. They are able to perform high-precision surgeries according to the doctor’s instructions, with an accuracy of millimeters. Compared to traditional surgical methods, surgical robots can reduce bleeding, shorten recovery time, and also reduce the physical burden on doctors to a certain extent. Versius surgical robot […]

A rimless wheel robot that can reliably overcome steps

DOI: 10.1007/s10015-024-00943-w Robots with wheels could potentially navigate a variety of indoor and outdoor environments, traveling for longer distances and with fewer risks of losing balance. While some wheeled robots have achieved very promising results in recent years, most of them are unable […]

DESI first-year data delivers unprecedented measurements of the expanding universe

Scientists have analyzed the first batch of data from the Dark Energy Spectroscopic Instrument’s quest to map the universe and unravel the mysteries of dark energy. AFTER DARK MATTER: University of Rochester PhD student Zack Brown completed a shift at Kitt Peak National Observatory in Arizona in October 2023. The DESI instrument—the cylindrical black apparatus—is […]

Robots lend nurses a helping hand

A robot developed by two DTU graduates brings equipment to nurses so they can concentrate on patient-related tasks that only they can perform. In this way, Buddy—which the duo has aptly called their robot—can help alleviate the nursing shortage. Clinical Nurse Specialist at Bispebjerg Hospital Johanne Laursen Lykke has provided feedback on Buddy’s use, which […]

Better battery manufacturing: Robotic lab vets new reaction design strategy

New chemistries for batteries, semiconductors and more could be easier to manufacture, thanks to a new approach to making chemically complex materials that researchers at the University of Michigan and Samsung’s Advanced Materials Lab have demonstrated. Their new recipes use unconventional ingredients to make battery materials with fewer impurities, requiring fewer costly refinement steps and […]

Teaching doglike robots to walk on the moon’s dusty, icy surface

At an elevation of around 6,000 feet near Mount Hood, located roughly 70 miles east of Portland, an interdisciplinary team comprising members from the University of Pennsylvania, the University of Southern California, Texas A&M University, Georgia Institute of Technology, Oregon State University, Temple University, and NASA, embarked on a field mission. The group of engineers, cognitive scientists, geoscientists, and planetary scientists […]
