Robotically steered flexible needles navigate in tissue

ScienceDaily's AI News - Wed, 26/08/2015 - 08:21
Robotically steering flexible needles can reach their intended target in tissue with sub-millimetre level accuracy. A major advantage of steering flexible needles is that one can avoid obstacles or sensitive tissues and can re-orient the path of the needle in real time as you insert the needle.

Biophysicists take small step in quest for 'robot scientist'

Instantaneous motion for new soft robots

ScienceDaily's AI News - Mon, 17/08/2015 - 16:06
Soft machines and robots are capable of moving, jumping and gripping objects thanks to soft, inflatable segments called fluidic actuators. These actuators require large amounts of air or water to change shape, making the machines slow, bulky and difficult to untether but researchers have engineered a new, soft actuator that harnesses the power of instability to trigger instantaneous movement.

Computer scientists find mass extinctions can accelerate evolution

ScienceDaily's AI News - Wed, 12/08/2015 - 15:12
Computer scientists have found that robots evolve more quickly and efficiently after a virtual mass extinction modeled after real-life disasters such as the one that killed off the dinosaurs. Beyond implications for artificial intelligence, the research supports the idea that mass extinctions actually speed up evolution by unleashing new creativity in adaptations.

Computer scientists introduce new graphics software

ScienceDaily's AI News - Tue, 11/08/2015 - 21:55
Computer scientists unveiled a new software modeling program that uses sophisticated geometric matching and machine learning to mimic humans' perception of style, giving users powerful new tools to compare the style similarity of 3-D objects The new first-of-its-kind structure-transcending software can benefit several computer graphics applications, researchers say.

'Machine teaching' holds the power to illuminate human learning

ScienceDaily's AI News - Tue, 11/08/2015 - 16:01
Human learning is a complex, sometimes mysterious process. Most of us have had experiences where we have struggled to learn something new, but also times when we've picked something up nearly effortlessly. What if a fusion of computer science and psychology could help us understand more about how people learn, making it possible to design ideal lessons? That long-range goal is moving toward reality.

Depth-sensing camera gleans 3-D information in bright sunlight as well as darkness

ScienceDaily's AI News - Mon, 10/08/2015 - 12:36
Depth-sensing cameras, such as Microsoft's Kinect controller for video games, have become widely used 3-D sensors. Now, a new imaging technology addresses a major shortcoming of these cameras: the inability to work in bright light, especially sunlight.

Artificially evolved robots that efficiently self-organize tasks

ScienceDaily's AI News - Thu, 06/08/2015 - 14:44
Darwinian selection can be used to evolve robot controllers able to efficiently self-organize their tasks. Taking inspiration from the way in which ants organize their work and divide up tasks, researchers evolved complex robot behaviors using artificial evolution and detailed robotics simulations.

Online tool enables public to track 'tip-of-the tongue' states, speech errors

ScienceDaily's AI News - Wed, 05/08/2015 - 12:26
Researchers have produced a web-based tool allowing everyday people to engage in 'citizen science' by recording speech errors, something that is difficult to capture in the lab setting.

Giving robots a more nimble grasp

ScienceDaily's AI News - Tue, 04/08/2015 - 16:08
Engineers have now hit upon a way to impart more dexterity to simple robotic grippers: using the environment as a helping hand. The team has developed a model that predicts the force with which a robotic gripper needs to push against various fixtures in the environment in order to adjust its grasp on an object.

Computer games can pick up dyslexia in minority pupils

ScienceDaily's AI News - Mon, 03/08/2015 - 08:35
While pupils from minority groups are over-represented in Norwegian special needs education, practically no children from these groups are diagnosed with dyslexia. As a consequence many miss out on important help. Researchersare studying whether a computer game can pick up dyslexia in pupils from minority groups.

Robotic insect mimics Nature's extreme moves

ScienceDaily's AI News - Thu, 30/07/2015 - 16:24
By analyzing the natural mechanics of the water strider that enable it to launch off water's surface scientists have emulated this extreme form of locomotion in novel robotic insects.

Movement tracking technology sheds light on different speech disorders in children

ScienceDaily's AI News - Tue, 28/07/2015 - 09:23
Facial motion capture -- the same technology used to develop realistic computer graphics in video games and movies -- has been used to identify differences between children with childhood apraxia of speech and those with other types of speech disorders, finds a new study.

Object recognition for robots

ScienceDaily's AI News - Fri, 24/07/2015 - 10:54
A team of researchers specializes in SLAM, or simultaneous localization and mapping, the technique whereby mobile autonomous robots map their environments and determine their locations. Now these researchers have demonstrated how SLAM can be used to improve object-recognition systems, which will be a vital component of future robots that have to manipulate the objects around them in arbitrary ways.

New computer program first to recognize sketches more accurately than a human

New era in robotics: 3-D-printed robot is hard at heart, soft on the outside

ScienceDaily's AI News - Thu, 09/07/2015 - 14:51
Engineers have created the first robot with a 3-D-printed body that transitions from a rigid core to a soft exterior. The idea of blending soft and hard materials into the robot's body came from nature.The rigid layers make for a better interface with the device's electronic brains and power sources. The soft layers make it less vulnerable to damage when it lands after jumping.

Researchers design a new system to make overtaking safer on highways
