How smart technology gadgets can avoid speed limits

Science Daily - Robotics - Thu, 06/28/2018 - 15:50
Speed limits apply not only to traffic. There are limitations on the control of light as well, in optical switches for internet traffic, for example. Physicists now understand why it is not possible to increase the speed beyond a certain limit - and know the circumstances in which it is best to opt for a different route.

Personalized 'deep learning' equips robots for autism therapy

Science Daily - Robotics - Wed, 06/27/2018 - 21:05
Researchers have now developed a type of personalized machine learning that helps robots estimate the engagement and interest of each child during these interactions, using data that are unique to that child. Armed with this personalized 'deep learning' network, the robots' perception of the children's responses agreed with assessments by human experts, with a correlation score of 60 percent.

Closing the loop for robotic grasping

Science Daily - Robotics - Tue, 06/26/2018 - 00:28
Roboticists have developed a faster and more accurate way for robots to grasp objects, including in cluttered and changing environments, which has the potential to improve their usefulness in both industrial and domestic settings.

New 'e-dermis' brings sense of touch, pain to prosthetic hands

Science Daily - Robotics - Wed, 06/20/2018 - 22:10
Engineers have created an electronic 'skin' in an effort to restore a real sense of touch for amputees using prosthetics.

Robot bloodhound tracks odors on the ground

Science Daily - Robotics - Wed, 06/20/2018 - 17:59
Bloodhounds are famous for their ability to track scents over great distances. Now researchers have developed a modern-day bloodhound -- a robot that can rapidly detect odors from sources on the ground, such as footprints. The robot could even read a message written on the ground using odors as a barcode.

Controlling robots with brainwaves and hand gestures

The same researchers, who last year designed a tiny computer chip tailored to help honeybee-sized drones navigate, have now shrunk their chip design even further, in both size and power consumption.

Diagnostics of genetic cardiac diseases using stem cell-derived cardiomyocytes

Science Daily - Robotics - Tue, 06/19/2018 - 17:25
A new study demonstrates that with the use of artificial intelligence and machine learning, it is possible not only to accurately sort sick cardiac cell cultures from healthy ones, but also to differentiate between genetic cardiac diseases.

World's first intra-operative MRI-guided robot for bilateral stereotactic neurosurgery

Science Daily - Robotics - Tue, 06/19/2018 - 17:25
Scientists have recently designed the first neurosurgical robotic system capable of performing bilateral stereotactic neurosurgery inside a magnetic resonance imaging ('MRI') scanner.

Magnetic 3D-printed structures crawl, roll, and jump

Science Daily - Robotics - Wed, 06/13/2018 - 21:30
Engineers have created soft, 3D-printed structures whose movements can be controlled with a wave of a magnet, much like marionettes without the strings. The menagerie of structures that can be magnetically manipulated includes a smooth ring that wrinkles up, a long tube that squeezes shut, a sheet that folds itself, and a spider-like 'grabber' that can crawl, roll, jump, and snap together fast enough to catch a passing ball.

Automated robotic device for faster blood testing

Science Daily - Robotics - Wed, 06/13/2018 - 15:20
Researchers have created an automated blood drawing and testing device that provides rapid results, potentially improving the workflow in hospitals and other health-related institutions to allow health care practitioners to spend more time treating patients.

Computer program looks five minutes into the future

Science Daily - Robotics - Wed, 06/13/2018 - 15:20
Scientists have developed software that can look minutes into the future: The program learns the typical sequence of actions, such as cooking, from video sequences. Then it can predict in new situations what the chef will do at which point in time.

AI senses people's pose through walls

Science Daily - Robotics - Tue, 06/12/2018 - 14:07
A new wireless smart-home system could help detect and monitor disease and enable the elderly to 'age in place.'

A nanotech sensor that turns molecular fingerprints into bar codes

Science Daily - Robotics - Thu, 06/07/2018 - 19:10
A new system can detect and analyze molecules without the need for an infrared spectrometer. The system uses nanostructured metapixels to detect and then translate molecules' unique signatures into bar codes. The technology can be integrated into a compact sensor chip. It opens the door to large-scale image-based detection of materials using machine-learning technology.

Use artificial intelligence to identify, count, describe wild animals

Science Daily - Robotics - Tue, 06/05/2018 - 17:41
Photographs that are automatically collected by motion-sensor cameras can be automatically described by deep neural networks. The result is a system that can automate animal identification for up to 99.3 percent of images while still performing at the same 96.6 percent accuracy rate of crowdsourced teams of human volunteers.

Future robots need no motors

Science Daily - Robotics - Mon, 06/04/2018 - 16:25
Engineers have created a novel actuating material that can be powered by visible light, electricity, and other stimuli, and which may replace traditional bulky motors and pneumatic actuators with ones similar to mammalian skeletal muscles in the future.

Breakthrough in controlling DNA-based robots

Science Daily - Robotics - Fri, 06/01/2018 - 18:47
