Neuroscientists are taking inspiration from natural motor control to design new prosthetic devices that can better replace limb function. Researchers have tested a range of brain-controlled devices -- from wheelchairs to robots to advanced limbs -- that work with their users to intelligently perform tasks.
Designer's toolkit for dynamic DNA nanomachines: Arm-waving nanorobot signals new flexibility in DNA origami
Researchers have demonstrated a new approach to joining -- and reconfiguring -- modular DNA building units, by snapping together complementary shapes instead of zipping together strings of base pairs. This not only opens the way for practical nanomachines with moving parts, but also offers a toolkit that makes it easier to program their self-assembly.
Pioneering techniques in computer vision and robotics pave the way for future underwater surveying in Cardigan Bay
Scientists have been working with marine conservation groups to develop better techniques for studying the seabed which is vital for marine conservation and fisheries management.
Firefighters moving through smoke-filled buildings could save vital seconds and find it easier to identify objects and obstacles, thanks to revolutionary reins that enable robots to act like guide dogs.
Engineers have taken a leaf out of nature's book by equipping an artificial hand with muscles made from shape-memory wire. The new technology enables the fabrication of flexible and lightweight robot hands for industrial applications and novel prosthetic devices. The muscle fibers are composed of bundles of ultrafine nickel-titanium alloy wires that are able to tense and flex. The material itself has sensory properties allowing the artificial hand to perform extremely precise movements.
Researchers who develop snake-like robots have picked up a few tricks from real sidewinder rattlesnakes on how to make rapid and even sharp turns with their undulating, modular device. Working with colleagues at the Georgia Institute of Technology and Zoo Atlanta, they have analyzed the motions of sidewinders and tested their observations on CMU's snake robots.
Researchers in Japan have jointly developed a robot with four arms and four crawlers which can perform multiple tasks simultaneously to help clean up the rubble left after the 2011 quake-tsunami disasters in Minamisoma, Fukushima.
Future robotics: Think self-fixing bridges; shoes that optimize for walking, running; camouflaging cars
Advances in materials science, distributed algorithms and manufacturing processes are revolutionizing robotic materials. Prosthetics with a realistic sense of touch. Bridges that detect and repair their own damage. Vehicles with camouflaging capabilities. Advances in materials science, distributed algorithms and manufacturing processes are bringing all of these things closer to reality every day.
Since Quantum Games came online as a citizen science project to help scientists develop a quantum computer, the game has been played 400,000 times, making it possible for researchers to discover a kind of 'atlas of human thoughts.'
Using both robots and infants, a cognitive scientist and collaborators have found that posture is critical in the early stages of acquiring new knowledge. "This study shows that the body plays a role in early object name learning, and how toddlers use the body's position in space to connect ideas," an author said. "The creation of a robot model for infant learning has far-reaching implications for how the brains of young people work."
Computers are able to recognize objects in in photographs and other images, but how well can they 'understand' the relationships or implied activities between objects? Researchers have devised a 'visual Turing test' to evaluate how well computers perform at that task.
Biorobotics researchers have developed the first aerial robot able to fly over uneven terrain that is stabilized visually without an accelerometer. Called BeeRotor, it adjusts its speed and avoids obstacles thanks to optic flow sensors inspired by insect vision. It can fly along a tunnel with uneven, moving walls without measuring either speed or altitude.
Moves are being made to automate the identification of Saimaa ringed seals. This would bring new kinds of real-time information on how the extremely endangered species behaves, the movements of individual seals, and what happens to them. The final aim of an ongoing study on machine vision is to get a biometric passport for each individual Saimaa ringed seal. This happens on the basis of the unique fur patterns of each individual seal, using computer-based smart calculation and digital image processing. The aim is to store the information in a so-called Saimaa ringed seal database.
Who is the teacher: the student or the machine? By showing a robot how to write letters, children improve their writing skills and gain self-confidence.
Reading a text is something that each of us does at our own individual pace. This simple fact has been exploited by computer scientists who have developed a software system that recognizes how fast a text on a display screen is being read and then allows the text to scroll forward line by line at the right speed. The technology makes use of commercially available eye-tracking glasses, which are able to capture the motion of the user’s eyes and convert this into a reading speed.
A mechanical engineer and his team have developed a computer-controlled camera that enables their robotic ankle to see where it is going.
Researchers have come up with a more accurate way than currently possible to train computers to be able to digest data that comes in the form of images and extract the emotions they convey.
People typically consider doing the laundry to be a boring chore. But laundry is far from boring for artificial intelligence researchers. To AI experts, programming a robot to do the laundry represents a challenging planning problem because current sensing and manipulation technology is not good enough to identify precisely the number of clothing pieces that are in a pile and the number that are picked up with each grasp. People can easily cope with this type of uncertainty and come up with a simple plan. But roboticists for decades have struggled to design an autonomous system able to do what we do so casually--clean our clothes.
Researchers have developed a prototype of a social robot which supports independent living for the elderly, working in partnership with their relatives or carers.
Scientists have developed an octopus-like robot, which can zoom through water with ultra-fast propulsion and acceleration never before seen in human-made underwater vehicles. Most fast aquatic animals are sleek and slender to help them move easily through the water but cephalopods, such as the octopus, are capable of high-speed escapes by filling their bodies with water and then quickly expelling it to dart away. Inspired by this, scientists built a deformable octopus-like robot with a 3D printed skeleton with no moving parts and no energy storage device, other than a thin elastic outer hull.
