Robots reach for food processing
The processing of food at high volumes has traditionally posed many problems for robots and cobots, and has lagged behind other industries. Foods have a variety of shapes and sizes and can be delicate in nature. These variables can be challenging when a robot tries to grasp an item. The delicate often has strict requirements for quality, making them even harder to grasp (think: strawberries).
Non-automotive robot orders now represent 58% of the North American total. Unit sales to the food and consumer goods sector alone increased 29% in 2021 over 2020, according to Association for Advancing Automation (A3).
“More industries recognized that robotics could help reverse productivity declines and fill repetitive jobs human workers don’t want. It is no longer a choice whether to deploy robots and automation,” says Jeff Burnstein, president of A3. “It’s now an absolute imperative. As we’ve long believed—and users continue to confirm—robots help companies compete, ultimately creating more jobs to handle their growth.”
Soft robotic origami crawlers
Materials scientists aim to develop biomimetic soft robotic crawlers including earthworm-like and inchworm-like crawlers to realize locomotion via in-plane and out-of-plane contractions for a variety of engineering applications. While such devices can show effective motion in confined spaces, it is challenging to miniaturize the concept due to complex and limited actuation. In a new report now published in Science Advances, Qiji Ze and a team of scientists in mechanical engineering and aerospace engineering at Stanford University and the Ohio State University, U.S., described a magnetically actuated, small-scale origami crawler exhibiting in-plane contraction. The team achieved contraction mechanisms via a four-unit Kresling origami assembly to facilitate the motion of an untethered robot with crawling or steering capacity. The crawler overcame large resistances in severely confined spaces due to its magnetically tunable structural stiffness and anisotropy. The setup provided a contraption for drug storage and release with potential to serve as a minimally invasive device in biomedicine.
Navigating complicated terrains
Bioinspired crawling motion shows adaptation to complicated terrains due to its soft deformable dimensions. Researchers aim to engineer crawling for a variety of applications in limited or confined environments, including extraterrestrial exploration, tube inspection, and gastrointestinal endoscopy. Origami provides an appropriate method to generate contraction relative to structural folding, which can be adapted to engineer robotic crawlers. The team described Kresling patterns; a specific type of bioinspired, origami pattern used to generate axial contraction under torque or compressive force, coupled with a twist from the relative rotation of the device units. Ze et al illustrated a magnetically actuated small-scale origami crawler to induce effective in-plane crawling motions. The scientists developed a four-unit Kresling assembly and verified torque distribution on the crawler using finite element analysis to induce motion.
New method allows robot vision to identify occluded objects
When artificial intelligence systems encounter scenes where objects are not fully visible, they have to make estimations based only on the visible parts of the objects. This partial information leads to detection errors, and large training data is required to correctly recognize such scenes. Now, researchers at the Gwangju Institute of Science and Technology have developed a framework that allows robot vision to detect such objects successfully in the same way that we perceive them.
Robotic vision has come a long way, reaching a level of sophistication with applications in complex and demanding tasks, such as autonomous driving and object manipulation. However, it still struggles to identify individual objects in cluttered scenes where some objects are partially or completely hidden behind others. Typically, when dealing with such scenes, robotic vision systems are trained to identify the occluded object based only on its visible parts. But such training requires large datasets of objects and can be pretty tedious.
Associate Professor Kyoobin Lee and Ph.D. student Seunghyeok Back from the Gwangju Institute of Science and Technology (GIST) in Korea found themselves facing this problem when they were developing an artificial intelligence system to identify and sort objects in cluttered scenes. “We expect a robot to recognize and manipulate objects they have not encountered before or been trained to recognize. In reality, however, we need to manually collect and label data one by one as the generalizability of deep neural networks depends highly on the quality and quantity of the training dataset,” says Mr. Back.
A model that can help inexperienced users identify phishing emails
Phishing attacks are cyber-attacks through which criminals trick users into sending them money and sensitive information, or into installing malware on their computer, by sending them deceptive emails or messages. As these attacks have become increasingly widespread, developers have been trying to develop more advanced tools to detect them and protect potential victims.
Researchers at Monash University and CSIRO’s Data61 in Australia have recently developed a machine learning-based approach that could help users to identify phishing emails, so that they don’t inadvertently install malware or send sensitive data to cyber-criminals. This model was introduced in a paper pre-published on arXiv and set to be presented at AsiaCCS 2022, a cyber-security conference.
“We have identified a gap in current phishing research, namely realizing that existing literature focuses on rigorous ‘black and white’ methods to classify whether something is a phishing email or not,” Tingmin (Tina) Wu, one of the researchers who carried out the study, told TechXplore.
Iris Automation adds TruWeather tech to Casia G system
Safety avionics specialist Iris Automation has made a meteorological enhancement to its Casia G ground-based surveillance system with the integration of TruWeather Solutions sensors and services – a move aiming to add climate security to the company’s aerial detect-and-avoid protection.
Addition of a precision weather utility was a natural step in Iris Automation’s wider objective of ensuring flight safety of, and between, crewed aircraft and drones The company says local micro weather and low-altitude atmospheric conditions often differ considerably from those at higher levels. That differential creates a larger degree of weather uncertainty for aerial service providers, who weigh safety factors heavily into whether they make flights as planned or not.
Remote-controlled Robots, Revolutionizing the Way We Work
Remote work is expanding into many other areas besides office work. Robots and remote-control technology make a greater range of tasks possible, from stocking convenience stores, to operating heavy machinery and even serving as a labor force in space. A key advantage of remote-controlled robots is that they do not require the kind of complex programming found in automated robots, such as industrial robots that work in factories. This means that remote-controlled robots are more flexible, easily adapting to work that cannot be programmed. Greater use of this technology can allow robots to take over dangerous and exhausting work, subsequently helping to deal with labor shortages and improve work environments. In this episode, we’ll look at the forefront of remote robotics, and see examples of how this technology could transform work.

How to print a robot from scratch: Combining liquids, solids could lead to faster, more flexible 3D creations
Imagine a future in which you could 3D-print an entire robot or stretchy, electronic medical device with the press of a button—no tedious hours spent assembling parts by hand.
That possibility may be closer than ever thanks to a recent advancement in 3D-printing technology led by engineers at CU Boulder. In a new study, the team lays out a strategy for using currently-available printers to create materials that meld solid and liquid components—a tricky feat if you don’t want your robot to collapse.
“I think there’s a future where we could, for example, fabricate a complete system like a robot using this process,” said Robert MacCurdy, senior author of the study and assistant professor in the Paul M. Rady Department of Mechanical Engineering.
