Published 3D display could soon bring touch to the digital world
(via sciencedaily.com) Engineers have designed a new, shape-shifting display that can fit on a card table and allows users to draw 3D designs and more.
Published Reinforcement learning allows underwater robots to locate and track objects underwater
(via sciencedaily.com) A team has shown that reinforcement learning -i.e., a neural network that learns the best action to perform at each moment based on a series of rewards- allows autonomous vehicles and underwater robots to locate and carefully track marine objects and animals.
Published This 3D printed gripper doesn't need electronics to function
(via sciencedaily.com) This soft robotic gripper is not only 3D printed in one print, it also doesn't need any electronics to work.
Published Researchers develop low-cost sensor to enhance robots' sense of touch
(via sciencedaily.com) Researchers have developed an L3 F-TOUCH sensor to enhance tactile capabilities in robots, allowing it to 'feel' objects and adjust its grip accordingly.
Published A simpler method for learning to control a robot
(via sciencedaily.com) A new machine-learning technique can efficiently learn to control a robot, leading to better performance with fewer data.
Published Robotic hand rotates objects using touch, not vision
(via sciencedaily.com) Inspired by the effortless way humans handle objects without seeing them, engineers have developed a new approach that enables a robotic hand to rotate objects solely through touch, without relying on vision.
Published Robot preachers get less respect, fewer donations
(via sciencedaily.com) As artificial intelligence expands across more professions, robot preachers and AI programs offer new means of sharing religious beliefs, but they may undermine credibility and reduce donations for religious groups that rely on them.
Published Future AI algorithms have potential to learn like humans
(via sciencedaily.com) Memories can be as tricky to hold onto for machines as they can be for humans. To help understand why artificial agents develop holes in their own cognitive processes, electrical engineers have analyzed how much a process called 'continual learning' impacts their overall performance.
Published Allowing robots to explore on their own
(via sciencedaily.com) Scientists have developed a suite of robotic systems and planners enabling robots to explore more quickly, probe the darkest corners of unknown environments, and create more accurate and detailed maps. The systems allow robots to do all this autonomously, finding their way and creating a map without human intervention.
Published A faster way to teach a robot
(via sciencedaily.com) A new technique enables a human to efficiently fine-tune a robot that failed to complete a desired task with very little effort on the part of the human. Their system uses algorithms, counterfactual explanations, and feedback from the user to generate synthetic data it uses to quickly fine-tune the robot.
Published Saltwater or freshwater? Difference is large for the climate when we flood low lying areas
(via sciencedaily.com) Original source Researchers find large methane emissions: 'Do not flood low-lying areas with freshwater'. Their studies find that freshwater lakes emit much more methane than saltwater lagoons, bogs and wet meadows.
Published Bot inspired by baby turtles can swim under the sand
(via sciencedaily.com) This robot can swim under the sand and dig itself out too, thanks to two front limbs that mimic the oversized flippers of turtle hatchlings. It's the only robot that is able to travel in sand at a depth of 5 inches. It can also travel at a speed of 1.2 millimeters per second--roughly 4 meters, or 13 feet, per hour. This may seem slow but is comparable to other subterranean animals like worms and clams.
Published What causes mudslides and floods after wildfires? Hint: It's not what scientists thought
(via sciencedaily.com) Original source Scientists once assumed that flooding and mudslides after wildfires were linked to the waxy coating that builds up on charred soil, preventing water absorption. Researchers found that water flow came from absorbed water in both burnt and unburnt areas, suggesting that water was, in fact, being absorbed into burnt ground. The discovery provides valuable insights into where and when potential flooding and mudslides may occur and how landscapes recover after a wildfire.
Published Robotics: New skin-like sensors fit almost everywhere
(via sciencedaily.com) Researchers have developed an automatic process for making soft sensors. These universal measurement cells can be attached to almost any kind of object. Applications are envisioned especially in robotics and prosthetics.
Published Robot team on lunar exploration tour
(via sciencedaily.com) Original source Engineers are training legged robots for future lunar missions that will search for minerals and raw materials. To ensure that the robots can continue to work even if one of them malfunctions, the researchers are teaching them teamwork.
Published Salinity changes threatening marine ecosystems
(via sciencedaily.com) Original source A groundbreaking study reveals the critical yet severely understudied factor of salinity changes in ocean and coastlines caused by climate change.
Published Pump powers soft robots, makes cocktails
(via sciencedaily.com) Over the past several years, researchers have been developing soft analogues of traditionally rigid robotic components. In fluid-driven robotic systems, pumps control the pressure or flow of the liquid that powers the robot's movement. Most pumps available today for soft robotics are either too large and rigid to fit onboard, not powerful enough for actuation or only work with specific fluids. Researchers have now developed a compact, soft pump with adjustable pressure flow versatile enough to pump a variety of fluids with varying viscosity, including gin, juice, and coconut milk, and powerful enough to power soft haptic devices and a soft robotic finger.
Published Training robots how to learn, make decisions on the fly
(via sciencedaily.com) Original source Mars rovers have teams of human experts on Earth telling them what to do. But robots on lander missions to moons orbiting Saturn or Jupiter are too far away to receive timely commands from Earth. Researchers developed a novel learning-based method so robots on extraterrestrial bodies can make decisions on their own about where and how to scoop up terrain samples.
Published Revolutionary self-sensing electric artificial muscles
(via sciencedaily.com) Researchers have made groundbreaking advancements in bionics with the development of a new electric variable-stiffness artificial muscle. This innovative technology possesses self-sensing capabilities and has the potential to revolutionize soft robotics and medical applications. The artificial muscle seamlessly transitions between soft and hard states, while also sensing forces and deformations. With flexibility and stretchability similar to natural muscle, it can be integrated into intricate soft robotic systems and adapt to various shapes. By adjusting voltages, the muscle rapidly changes its stiffness and can monitor its own deformation through resistance changes. The fabrication process is simple and reliable, making it ideal for a range of applications, including aiding individuals with disabilities or patients in rehabilitation training.
Published GPT detectors can be biased against non-native English writers
(via sciencedaily.com) Original source Researchers show that computer programs commonly used to determine if a text was written by artificial intelligence tend to falsely label articles written by non-native language speakers as AI-generated. The researchers caution against the use of such AI text detectors for their unreliability, which could have negative impacts on individuals including students and those applying for jobs.
