"Considérez-vous la fusion de l’homme et de la machine comme inéluctable ?

Certainement, je pense que c’est une étape inévitable de notre évolution. Certaines personnes pourront cependant choisir de rester humaines – c’est leur droit. Mais quelque chose me dit qu’elles constitueront une sorte d’espèce inférieure." Kevin Warwick, http://www.laspirale.org)

Kevin Warwick, directeur du laboratoire de cybernétique de l'université de Reading (UK) et spécialiste en robotique, étudie les interfaces directes entre les systèmes informatiques et le système nerveux humain. Il s'est fait greffer dans le bras des électrodes directement reliés à son système nerveux pour le faire commander par un ordinateur. Il travaille sur la mise au point d'une puce qui, implantée dans le cerveau, permetterait à deux êtres humains de communiquer par "télépathie"... Il prévoit les guerres où les soldats commanderont leurs armes de chez eux.

Forget traditional robots that look like humans, these days robots come in all different shapes and sizes. But it?s not only their appearance that is changing - robotics researchers are also thinking very differently about how the function, as discussed in a review this week in the journal Science. Whereas the focus used to be on getting robots to perform specific tasks, like packaging chocolates in a manufacturing plant, researchers are now looking at creating more complex machines that can deal with unpredictable circumstances.

So it shouldn?t be a surprise that they are turning to living creatures for inspiration. The video below shows some robots that have recently been developed: a salamander robot moves from water to land just like the real animal would, Waalbot walks on walls using an adhesive inspired by the fibers on geckos? feet and a sophisticated Japanese robot is made of modules that can communicate with each other to tackle whatever obstacle it?s confronted with.

Although some of these robots look like the real thing, it?s not about replicating nature but rather understanding the basic principles of biology and transferring those that are most useful. Creating a model is often a good first step: to make the salamander robot, for example, researchers replicated the animal?s spinal cord and used a similar system to control their robot?s movement.

But there is still a lot to learn about animal behaviour and how brain and body interact with each other in a changing environment. Can you think of some interesting animal behaviours that might be good inspiration for robot makers?

The Pentagon is looking for better ways to prevent chemical weapon attacks. So military researchers are implanting insect larvae with WMD-detectors - turning them into cyborg-critters that specialize in tracking down mustard gas. Naturally.

In 2005, the military trained honeybees to sniff out land mines. Then, Darpa’s HI-MEMS program started trying to machinize insects instead. So far researchers have implanted micro-mechanical components into larval moths and created remote-controlled beetles. Those initial HI-MEMS efforts seemed designed for reconnaissance missions - this time, the Pentagon wants its modified bugs to detect and differentiate between chemical agents.

The Pentagon has handed researchers at Agiltron Corporation a contract to implant larvae with “high sensitivity micromechanical chemical sensors” that run on electric power collected with an embedded “electromagnetic harvester.” The implanted system would include muscle actuators, so different tics or twitches would signal the detection of different chemicals.

In separate deals, the Pentagon is also backing research into an insect-mounted device powered by fuel cells, for a more reliable energy source. “This solution offers several advantages over the existing electromechanical methods; 50-100X higher power density, power-generation independent of insect species, and power generation in absence of insect motion,” according to the contract award.

And to really bring the critters into the 21st century, the military wants to hook them up with their own wireless network - using chirps instead of Tweets. They’re funding two projects that would create “a mobile ad hoc network” for vocal insects like crickets and cicadas.


Insects will be equipped with embedded MEMS transceivers that pick up modulated calling sounds from nearby insects. Once the information in a call is extracted by the transceiver, the information code is applied to an electromechanical device on board the insect that modulates the insect calls, thereby retransmitting the information to another insect, and so on.

The instant-insect message would then be transmitted to humans or computerized systems, which could decode the covert chirp.

Sure, swarms of teensy biochemical detectors would be valuable in war-zones. But fly-swatters take note: project proposals reference “civilian and defense applications,” so your bug-squashing habit might soon make you a threat to national security.

The telepathic abilities that feature in the film X2 are a step closer to reality

The telepathic abilities that feature in the film X2 are a step closer to reality


Scientists have discovered how to “read” minds by scanning brain activity and reproducing images of what people are seeing — or even remembering.


Researchers have been able to convert into crude video footage the brain activity stimulated by what a person is watching or recalling.


The breakthrough raises the prospect of significant benefits, such as allowing people who are unable to move or speak to communicate via visualisation of their thoughts; recording people’s dreams; or allowing police to identify criminals by recalling the memories of a witness.


However, it could also herald a new Big Brother era, similar to that envisaged in the Hollywood film Minority Report, in which an individual’s private thoughts can be readily accessed by the authorities.


Jack Gallant and Shinji Nishimoto, two neurologists from the University of California, Berkeley, last year managed to correlate activity in the brain’s visual cortex with static images seen by the person. Last week they went one step further by revealing that it is possible to “decode” signals generated in the brain by moving scenes.


In an experiment which has yet to be peer reviewed, Gallant and Nishimoto, using functional magnetic resonance imaging (fMRI) technology, scanned the brains of two patients as they watched videos.


A computer programme was used to search for links between the configuration of shapes, colours and movements in the videos, and patterns of activity in the patients’ visual cortex.


It was later fed more than 200 days’ worth of YouTube internet clips and asked to predict which areas of the brain the clips would stimulate if people were watching them.


Finally, the software was used to monitor the two patients’ brains as they watched a new film and to reproduce what they were seeing based on their neural activity alone.


Remarkably, the computer programme was able to display continuous footage of the films they were watching — albeit with blurred images.


In one scene which featured the actor Steve Martin wearing a white shirt, the software recreated his rough shape and white torso but missed other details, such as his facial features.


Another scene, showing a plane flying towards the camera against a city skyline, was less successfully reproduced. The computer recreated the image of the skyline but omitted the plane altogether.


“Some scenes decode better than others,” said Gallant. “We can decode talking heads really well. But a camera panning quickly across a scene confuses the algorithm.


“You can use a device like this to do some pretty cool things. At the moment when you see something and want to describe it to someone you have to use words or draw it and it doesn’t work very well.


“You could use this technology to transmit the image to someone. It might be useful for artists or to allow you to recover an eyewitness’s memory of a crime.”


Such technology may not be confined to the here and now. Scientists at University College London have conducted separate tests that detect, with an accuracy of about 50%, memories recalled by patients.


The discoveries come amid a flurry of developments in the field of brain science. Researchers have also used scanning technology to measure academic ability, detect early signs of Alzheimer’s and other degenerative conditions, and even predict the decision a person is about to make before they are conscious of making it.


Such developments may have controversial ramifications. In Britain, fMRI scanning technology has been sold to multinational companies, such as Unilever and McDonald’s, enabling them to see how we subconsciously react to brands.


In America, security agencies are researching the use of brain scanners for interrogating prisoners, and Lockheed Martin, the US defence contractor, is reported to have studied the possibility of scanning brains at a distance.


This would allow an individual’s thoughts and anxieties to be examined without their knowledge in sensitive locations such as airports.


Russell Foster, a neuroscientist at Oxford University, said rapid advances in the field were throwing up ethical dilemmas.


“It’s absolutely critical for scientists to inform the public about what we are doing so they can engage in the debate about how this knowledge should be used,” he said.


“It’s the age-old problem: knowledge is power and it can be used for both good and evil.”

Le fabricant de robot Boston Dynamics  a exposé pour la première fois Mardi un nouveau prototype de robot qui marche debout comme un être humain.  
 
 Wired.com rapporte : « Petman trouve son équilibre tout seul et se déplace librement ; capable de marcher, ramper et de faire toute une série de mouvement de gymnastique durant l'exposition à des agents de guerre chimique, » promet la compagnie.

« Petman simulera également la physiologie humaine dans sa tenue de protection en contrôlant la température, l'humidité et la transpiration si nécessaire, tout pour fournir des conditions d'essai réalistes.  »

 De même que le robot BigDog de Boston Dynamics, Petman se tient debout, même lorsqu'il est bousculé. Et il se déplace à 3,2 Miles par heure, tout juste comme une personne de chair et de sang. Petman pourrait être juste une nouvelle tentative parmi nombre d’autres tentatives des fabricants de robot pour fabriquer un ensemble simulé de jambes bipèdes. Mais je n'en ai pas vu d’autre qui soit aussi proche de la réalité.

 « J’aime bien le fait que le torse de PETMAN ressemble à une stéréo et j'espère qu'un jour Boston Dynamic fera des ajustements pour permettre au robot de circuler dans un  district d’affaires d'une petite ville, marchant et s’intégrant au paysage tout en diffusant du rap old school, » a indiqué Doug Aamoth de CrunchGear

 Boston Dynamics est également le créateur du « Big Dog, » une mule quadrupède qui accompagne les soldats.

April 2008 - In 1998, when Kevin Warwick, researcher and Professor of Cybernetics at the University of Reading, England, implanted a silicon chip transponder into his left arm and connected it to his nervous system, he became the world's first cyborg: a man-machine hybrid. Some call Kevin Warwick a pioneer in the field of neuro-surgical implantation, others think he is a dangerous scientist who has gone crazy and wants to change mankind's evolution by creating a superior race: the cyborgs. In this video interview we talk about ultra-sonic senses, brain-to-brain telepathic communication, the therapeutic benefits of his experiments and why he think's he won't be the only cyborg on this planet in the future.
