Bird-like robots could assist in medical emergencies and hunt down drones

A bird flaps its wings, glides using air currents and then smoothly descends to perch on a pole. But this is not just any bird, it's a robot bird. And robots like these could in the next decade be used to respond to emergencies or to hunt down drones posing a threat to safety or security.

A helping hand for working robots

Until now, competing types of robotic hand designs offered a trade-off between strength and durability. One commonly used design, employing a rigid pin joint that mimics the mechanism in human finger joints, can lift heavy payloads, but is easily damaged in collisions, particularly if hit from the side. Meanwhile, fully compliant hands, typically made of molded silicone, are more flexible, harder to break, and better at grasping objects of various shapes, but they fall short on lifting power.

Researchers create robot that smiles back

While our facial expressions play a huge role in building trust, most robots still sport the blank and static visage of a professional poker player. With the increasing use of robots in locations where robots and humans need to work closely together, from nursing homes to warehouses and factories, the need for a more responsive, facially realistic robot is growing more urgent.

Robotics group announces an ostrich-like, multi-purpose bot called Cassie

Agility Robotics, a branch of Oregon State University, has just revealed a new bipedal robot called Cassie. Unlike the many four-legged and four-wheeled robots currently in existence, Cassie will walk much more like a human. This kind of movement allows for far easier travel across diverse types of terrain while delivering packages or even contributing to disaster relief efforts.

Using a virtual linkage representation algorithm to improve functionally of a robot hand

A team of researchers at Yale University has developed a new kind of algorithm to improve the functionally of a robot hand. In their paper published in the journal Science Robotics, the group describes their algorithm and then demonstrate, via videos, how it can be used.

Helping robots learn what they can and can’t do in new situations

The models that robots use to do tasks work well in the structured environment of the laboratory. Outside the lab, however, even the most sophisticated models may prove inadequate in new situations or in difficult to model tasks, such as working with soft materials like rope and cloth.

Magnetically propelled cilia power climbing soft robots and microfluidic pumps

The rhythmic motions of hair-like cilia move liquids around cells or propel the cells themselves. In nature, cilia flap independently, and mimicking these movements with artificial materials requires complex mechanisms. Now, researchers reporting in ACS Applied Materials & Interfaces have made artificial cilia that move in a wave-like fashion when a rotating magnetic field is applied, making them suitable for versatile, climbing soft robots and microfluidic devices.

MOBLOT: A theoretical model that describes molecular oblivious robots

Research focusing on swarm robotics typically uses theoretical approaches to describe robotic systems in an abstract way. A theoretical model that is often used in robotics studies is OBLOT, an approach that represents robots as simple systems, all identical, without a memory and unable to communicate with each other.

Robotic navigation tech will explore the deep ocean

On May 14, the National Oceanic and Atmospheric Administration (NOAA) ship Okeanos Explorer will depart from Port Canaveral in Florida on a two-week expedition led by NOAA Ocean Exploration, featuring the technology demonstration of an autonomous underwater vehicle. Called Orpheus, this new class of submersible robot will showcase a system that will help it find its way and identify interesting scientific features on the seafloor.
