Japanese scientists aim to create robot-insects; Bilim adamları böcek robot geliştiriyor

Böcek beyninin şemasını çıkaran Japon bilimadamları, robot-böcek geliştirilmesinde bir adım daha attı.
Tokyo Üniversitesi’nin Bilim ve Teknolojik Araştırmalar Enstitüsü’nde görev yapan Profesör Ryohei Kanzaki ve ekibi, yaklaşık 30 yıldır böcek beynini araştırıyor. Her ne kadar temel amacı insan beynini araştırıp, oluşan hasarların tedavisinde yeni yöntemler bulmak olsa da Kanzaki, melez robot-böceklerin üretiminin öncülerinden biri durumunda. (bilim.org)

TOKYO (AFP) — Police release a swarm of robot-moths to sniff out a distant drug stash. Rescue robot-bees dodge through earthquake rubble to find survivors.

These may sound like science-fiction scenarios, but they are the visions of Japanese scientists who hope to understand and then rebuild the brains of insects and programme them for specific tasks.

Ryohei Kanzaki, a professor at Tokyo University’s Research Centre for Advanced Science and Technology, has studied insect brains for three decades and become a pioneer in the field of insect-machine hybrids.

 

Beynimiz kullandığımız aletleri uzuvlarımız sayıyor- Our brains incorporate use tools into this a physical map of the body

Beyniniz dış fırçalarken fırçayı, ya da maşayla bir şeyi tutarken maşayı sizin bir parçanız gibi görüyor. Fransa’daki Claude Bernard Üniversitesi’nde yapılan son araştırmayla, beynin kullanılan aletleri geçici uzuvlar olarak görüdüğüne dair yaklaşık 100 yıldır var olan hipotezin doğru olduğu kanıtlandı.
The brain maintains a physical map of the body, with different areas in charge of different body parts. Researchers have suggested that when we use tools, our brains incorporate them into this map.

To test the idea, Alessandro Farné of the University of Claude Bernard in Lyon, France, and colleagues attached a mechanical grabber to the arms of 14 volunteers. The modified subjects then used the grabber to pick up out-of-reach objects.

 

Mind-Controlled Wheelchair Düşünce kontrollü tekerlekli sandalye

İspanyol bilimadamları, düşünce gücüyle hareket eden tekerlekli sandalye geliştirdiler. Yakında, engelliler sadece düşünerek istedikleri yere gidebilecekler. İspanyol bilimadamlarını geliştirdiği tekerlekli sandalyenin kontrolü düşünce ile sağlanıyor.

Sandalyede, çevrenin üç boyutlu resmini çıkaran bir lazer tarayıcı bulunuyor. Oluşturulan resim, sandalyedeki bir ekrana aktarılıyor, kullanıcı da bu resimde nereye gideceğine yoğunlaşıyor.

Bu sırada kullanıcının başına bağlanan 16 elektrot yardımıyla ekrana yoğunlaşıldığında oluşan beyin aktiviteleri ile tekerlekli sandalye yönlendiriliyor. İstenilen yere gidilebilmesi için sandalyenin tekerleklerinde de çeşitli sensörler yer alıyor.
A research team of the University of Zaragoza has developed a prototype of a brain-actuated wheelchair. During May 2008, five subjects, only using their thoughts, successfully carried navigation and manoeuvrability tasks with the wheelchair in the University. The non-invasive method to record the human neural activity was the EEG and the wheelchair was robotized and equipped with a laser sensor.

 

Okyanus Dalgalarından elektrik üretmek, Ocean wave energy

nsf_graphic

1998 yılından beri 270000 dolarlık araştırma bütçesiyle okyanusdan elektrik üretmeye çalışan, Oregon State Üniversitesi araştırma ekibi okyanus dalga enerjisinin önemini anlatmaktadır.

This past summer, Annette von Jouanne and Alan Wallace, professors in OSU’s School of Electrical Engineering and Computer Science, led the first of what will be several community meetings centered around bringing wave energy to the Oregon coast. In front of a standing room only crowd, they answered questions about energy potential, new jobs, environmental consequences, advanced technology, and dependence on foreign energy sources. Recognized as national leaders of ocean wave energy, von Jouanne and Wallace have developed several direct drive ocean buoys capable of converting the power in ocean waves to electrical energy. The coast near Reedsport has been identified as the

 

The illusion of levitating objects in the air. Cisimleri havada tutma

ScienceDaily (Jan. 7, 2009) — Magicians have long created the illusion of levitating objects in the air. Now researchers have actually levitated an object, suspending it without the need for external support. Working at the molecular level, the researchers relied on the tendency of certain combinations of molecules to repel each other at close contact, effectively suspending one surface above another by a microscopic distance.
Henüz bir cismin havada tutulması gerçekleştirilmedi ancak bilimciler, doğadaki en küçük parçacıkları yöneten ilkelerden oluşan “kuantum mekaniğinin” sır dolu güçlerini kullanarak, bunun nasıl başarılabileceğinin yolunu keşfetti.

Researchers from Harvard University and the National Institutes of Health (NIH) have measured, for the first time, a repulsive quantum mechanical force that could be harnessed and tailored for a wide range of new nanotechnology applications.

The study, led by Federico Capasso, Robert L. Wallace Professor of Applied Physics at Harvard’s School of Engineering and Applied Science (SEAS), will be published as the January 8 cover story of Nature.

The discovery builds on previous work related to what is called the Casimir force. While long considered only of theoretical interest, physicists discovered that this attractive force, caused by quantum fluctuations of the energy associated with Heisenberg’s uncertainty principle, becomes significant when the space between two metallic surfaces, such as two mirrors facing one another, measures less than about 100 nanometers.

 

Bionik gözlerde yeni yöntem most popular solutions so far were bionic eyes Jeffrey Olsen

Colorado Üniversite hastanesinden Jeffrey Olsen göz kusurlarında kullanılan işlemcilerin yerine kullanılacak bir yöntem geliştirdi.

Bu yöntemde işlemci yerine ışığı alıp, kuvvetlendiren dönüştürücüler kullanılıyor.  bu dönüştürücü malzemeler halen çalışan göz hücrelerine bu ğüçlendirilmiş ışığı göndererek, daha iyi görme sağlıyor.

The number of people with damaged vision is getting bigger every day. That can be due to various reasons — looking at computer/TV displays, diabetes, and many more. That’s why technology is obliged to find a solution that will be able to repair vision and “renew” people’s eyes.

One of the most popular solutions so far were bionic eyes. A silicon chip gets implanted into the eye to electrically stimulate the retina’s nerves in response to light. Their main flaw of these devices is their size — because of it they block light that would have fallen on healthy parts of the retina and they can also cause tissue damage, such as tearing.

Jeffrey Olsen, a doctor from University of Colorado Hospital, has invented a brand new technique — amplifying the light that reaches the retina using the eye’s still functioning light-sensitive cells.

That’s where quantum dots step in. “Light amplification could be achieved by implanting quantum dots – nanoscale specks of semiconductor – into the retina,” he says. These fluoresce when hit by photons and would have the effect of making any received retinal image brighter.
Quantum dots have some very important characteristics — they require no external power source, their are relatively small in size, and can be coated with a bioactive material that causes them to become lodged in only specific tissues in the retina.

Tests were done on rats and they have been successful. Rats that had quantum dots injected into their retinas afterwards had more electrical activity in their retinas than those that received control injections of saline, or no treatment at all.

 

Tiyatro oyuncusu robot, Robot actors to make stage debut in Osaka U. play

OSAKA–Robotic technology will enter unfamiliar territory Tuesday when two humanoid robots make their stage acting debut alongside human performers in a play at Osaka University.

The robots are a part of a new production penned by renowned playwright Oriza Hirata called “Hataraku Watashi” (I, Worker), which focuses on a couple who live in the near future. The couple owns two housekeeping robots, one of which suddenly loses its motivation to work.

In the 20-minute play, Hirata, also a professor at the university in Toyonaka, Osaka Prefecture, raises questions about the relationship between humanity and technology.

Hirata, Hiroshi Ishiguro, a professor specializing in robot technology at the university’s graduate school, and others began the project in July in an attempt to introduce cutting edge robotics to the arts.

The robots featured in the play are called Wakamaru and are one-meter-tall and weigh 30 kilograms. The Wakamaru model was originally designed by Mitsubishi Heavy Industries Ltd. for customer service use.

The project team took two months to write detailed control software that enables the robots to move and deliver lines with nuance.

Members of Seinendan, a theater company led by Hirata, began rehearsing with their robot cast mates this month.

The producers hope to develop the play into a full-scale production for the public in 2010 if the debut is successful.
