Published Robots can help improve mental wellbeing at work -- as long as they look right
(via sciencedaily.com) Robots can be useful as mental wellbeing coaches in the workplace -- but perception of their effectiveness depends in large part on what the robot looks like.
Published Researchers develop soft robot that shifts from land to sea with ease
(via sciencedaily.com) Most animals can quickly transition from walking to jumping to crawling to swimming if needed without reconfiguring or making major adjustments. Most robots cannot. But researchers have now created soft robots that can seamlessly shift from walking to swimming, for example, or crawling to rolling using a bistable actuator made of 3D-printed soft rubber containing shape-memory alloy springs that react to electrical currents by contracting, which causes the actuator to bend. The team used this bistable motion to change the actuator or robot's shape. Once the robot changes shape, it is stable until another electrical charge morphs it back to its previous configuration.
Published Ultra-soft and highly stretchable hydrogel-based sensor for monitoring overactive bladder
(via sciencedaily.com) Researchers have developed an ultra-soft and highly stretchable tissue-adhesive hydrogel-based multifunctional implantable sensor for monitoring of overactive bladder.
Published New breakthrough enables perfectly secure digital communications
(via sciencedaily.com) Researchers have achieved a breakthrough to enable 'perfectly secure' hidden communications for the first time. The method uses new advances in information theory methods to conceal one piece of content inside another in a way that cannot be detected. This may have strong implications for information security, besides further applications in data compression and storage.
Published Fighting friction to protect machinery
(via sciencedaily.com) Moving parts in mechanical come into regular contact, leading to wear and tear. Now, researchers have developed a contact control system, driven by artificial intelligence, to greatly reduce contact between damaged parts.
Published Robot provides unprecedented views below Antarctic ice shelf
(via sciencedaily.com) With the help of an underwater robot, known as Icefin, a U.S.- New Zealand research team has obtained an unprecedented look inside a crevasse at Kamb Ice Stream -- revealing more than a century of geological processes beneath the Antarctic ice.
Published Hansel and Gretel's breadcrumb trick inspires robotic exploration of caves on Mars and beyond
(via sciencedaily.com) Future space missions likely will send robots to scout out underground habitats for astronauts. Engineers have now developed a system that would enable autonomous vehicles to explore caves, lava tubes and even oceans on other worlds on their own.
Published Tiny new climbing robot was inspired by geckos and inchworms
(via sciencedaily.com) A tiny robot that could one day help doctors perform surgery was inspired by the incredible gripping ability of geckos and the efficient locomotion of inchworms.
Published Reaching like an octopus: A biology-inspired model opens the door to soft robot control
(via sciencedaily.com) Octopus arms coordinate nearly infinite degrees of freedom to perform complex movements such as reaching, grasping, fetching, crawling, and swimming. How these animals achieve such a wide range of activities remains a source of mystery, amazement, and inspiration. Part of the challenge comes from the intricate organization and biomechanics of the internal muscles.
Published This new sensor can detect mercury ions with just a tap
(via sciencedaily.com) Although many measures are in place to prevent contamination, pollutants, such as mercury and lead, can still end up in the environment. Sensing them often requires complicated processes, but what if you could detect them with the tap of a fingertip? Researchers have now developed a self-powered nanosensor that can discover small amounts of mercury ions and immediately report the result.
Published Robot helps students with learning disabilities stay focused
(via sciencedaily.com) Engineering researchers are successfully using a robot to help keep children with learning disabilities focused on their work.
Published Chromo-encryption method encodes secrets with color
(via sciencedaily.com) In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
Published Researchers develop new, automated, powerful diagnostic tool for drug detection
(via sciencedaily.com) Biomedical engineers present a robust new method for accurately measuring and identifying eight antidepressants most commonly prescribed to women.
Published Compact, non-mechanical 3D lidar system could make autonomous driving safer
(via sciencedaily.com) A new system represents the first time that the capabilities of conventional beam-scanning lidar systems have been combined with those of a newer 3D approach known as flash lidar. The nonmechanical 3D lidar system is compact enough to fit in the palm of the hand and solves issues of detecting and tracking poorly reflective objects.
Published Bite this! Mosquito feeding chamber uses fake skin, real blood
(via sciencedaily.com) Bioengineers and experts in tropical medicine have invented a new way of studying mosquito feeding behavior using technology instead of live volunteers. Their open-source design combines automated cameras, artificial intelligence and blood-infused, 3D-printed 'synthetic skin.'
Published Engineers devise a modular system to produce efficient, scalable aquabots
(via sciencedaily.com) Researchers developed a new approach to building deformable underwater robots, using simple repeating substructures. The team demonstrated the new system in two different example configurations, one like an eel and the other a wing-like hydrofoil.
Published Interactive cyber-physical human: Generating contact-rich whole-body motions
(via sciencedaily.com) Performing human-like motions that involve multiple contacts is challenging for robots. In this regard, a researcher has envisioned an interactive cyber-physical human (iCPH) platform with complementary humanoid (physical twin) and simulation (digital twin) elements. iCPH combines human measurement data, musculoskeletal analysis, and machine learning for data collection and augmentation. As a result, iCPH can understand, predict, and synthesize whole-body contact motions.
Published Robot: I'm sorry. Human: I don't care anymore!
(via sciencedaily.com) Humans are less forgiving of robots after multiple mistakes -- and the trust is difficult to get back, according to a new study.
Published Contributing to the utilization of big data! Developing new data learning methods for artificial intelligence
(via sciencedaily.com) A research group has developed a new learning method for artificial intelligence that combines classification performance for data with multiple labels with the ability to learn continually from data. Numerical experiments on real-world multi-label data indicate that the new method outperforms conventional approaches. The simplicity of this algorithm makes it easy to integrate it with other algorithms to devise new ones.
Published Legged robots need more testing before real-world use
(via sciencedaily.com) When it comes to the 'evolution' of mobile robots, it may be a long time before legged robots are able to safely interact in the real world, according to a new study.
