Ready for duty: Healthcare robots get good prognosis for next pandemic

Not long after the 1918 Spanish flu pandemic, Czech writer Karel Čapek first introduced the term "robot" to describe artificial people in his 1921 sci-fi play R.U.R. While we have not yet created the highly intelligent humanoid robots imagined by Čapek, the robots most commonly used today are complex systems that work alongside humans, assisting with an ever-expanding set of tasks.

How tiny machines become capable of learning

Living organisms, from bacteria to animals and humans, can perceive their environment and process, store and retrieve this information. They learn how to react to later situations using appropriate actions. A team of physicists at Leipzig University led by Professor Frank Cichos, in collaboration with colleagues at Charles University Prague, have developed a method for giving tiny artificial microswimmers a certain ability to learn using machine learning algorithms. They recently published a paper on this topic in the journal Science Robotics.

Electronics-free DraBot dragonfly signals environmental disruptions

Engineers at Duke University have developed an electronics-free, entirely soft robot shaped like a dragonfly that can skim across water and react to environmental conditions such as pH, temperature or the presence of oil. The proof-of-principle demonstration could be the precursor to more advanced, autonomous, long-range environmental sentinels for monitoring a wide range of potential telltale signs of problems.

Underwater swimming robot responds with feedback from soft ‘lateral line’

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Germany, from Seoul National University in Korea and from the Harvard University in the US, successfully developed a predictive model and closed-loop controller of a soft robotic fish, designed to actively adjust its undulation amplitude to changing flow conditions and other external disturbances. Their work "Modeling and Control of a Soft Robotic Fish with Integrated Soft Sensing" was published in Wiley's Advanced Intelligent Systems journal, in a special issue on "Energy Storage and Delivery in Robotic Systems."

Researchers’ algorithm designs soft-bodied robots that sense their own positions in space

There are some tasks that traditional robots—the rigid and metallic kind—simply aren't cut out for. Soft-bodied robots, on the other hand, may be able to interact with people more safely or slip into tight spaces with ease. But for robots to reliably complete their programmed duties, they need to know the whereabouts of all their body parts. That's a tall task for a soft robot that can deform in a virtually infinite number of ways.

Expressing some doubts: Comparative analysis of human and android faces could lead to improvements

Researchers from the Graduate School of Engineering and Symbiotic Intelligent Systems Research Center at Osaka University used motion capture cameras to compare the expressions of android and human faces. They found that the mechanical facial movements of the robots, especially in the upper regions, did not fully reproduce the curved flow lines seen in the faces of actual people. This research may lead to more lifelike and expressive artificial faces.

First collaborative robot to work with vehicles in motion

The Ph.D. thesis by Daniel Teso-Fernández de Betoño of the UPV/EHU Faculty of Engineering in Vitoria-Gasteiz has resulted in a mobile, collaborative platform capable of performing tasks in motion at the Mercedes-Benz plant in the capital of Alava. The research opens up a new field for improving the ergonomics of these workstations and for the robot and human to collaborate by performing tasks together.

RoboEYE: A semi-autonomous and gaze-guided wheelchair

Recent technological advancements have enabled the development of new tools to assist people with different types of disabilities, allowing them to move more freely in their surroundings and complete a number of everyday tasks. These include a broad range of smart technologies and devices, ranging from home assistants to mobile robots and bionic limbs.

Engineers utilize ‘swarmalation’ to design active materials for self-regulating soft robots

During the swarming of birds or fish, each entity coordinates its location relative to the others, so that the swarm moves as one larger, coherent unit. Fireflies on the other hand coordinate their temporal behavior: within a group, they eventually all flash on and off at the same time and thus act as synchronized oscillators.

Robots can use eye contact to draw out reluctant participants in group interactions

Eye contact is a key to establishing a connection, and teachers use it often to encourage participation. But can a robot do this too? Can it draw a response simply by making eye contact, even with people who are less inclined to speak up? A recent study suggests that it can.
