Smart robot arm can follow your lead without coding

Posted by in categories: 3D printing, computing, mobile phones, robotics/AI

You might not be able to control the 7Bot robotic arm with your mind or your eyes, but at least it’ll only cost you around $350 — cheaper than an iPhone, its creators point out — to get one. Even better, you don’t need to know how to code to program it: just physically guide the arm or use a gesture control device like a Kinect or a Leap motion sensor to make it mimic your movements. In the video below the fold and on its Kickstarter page, you can see it doing calligraphy after a team member’s grandfather physically taught it how. The team also managed make it paint cherry blossoms and do basic mathematics, and we’ll bet you can teach it other productive things, like how to terrorize your cat.

If you prefer the more hands-off approach, you can remotely control it using its 3D visualization app on a computer. And, in case you’re more tech-savvy than the average user, you can program it using the C and C++ open source APIs the 7Bot team provides. In addition to the basic model, the team also offers packages with more features, such as a version with two arms and one that comes with a 3D printer, though they’re also understandably more expensive. According to its campaign page, rewards should start shipping out as soon as January 2016, but as always, it’s best not to treat Kickstarter and other crowdfunding websites as a store.

How the Cutting Edge of Virtual Reality Is Making the Real World Seem Boring

Posted by in categories: computing, materials, virtual reality

In the television series Star Trek, virtual reality-chambers called “holodecks” take humans into computer-generated worlds where they interact with avatars — and with each other. Imagine being able to visit a distant planet or Tahiti during your lunch break. In Star Trek, holodecks come into existence in the 24th century and reproduce all sensory perceptions, including touch and smell.

Chambers that replicate the touch and feel of solid materials are still a decade or two away. But virtual reality worlds that are amazingly similar to what we saw in Star Trek are already here. Hundreds of companies are working on virtual reality hardware, software, applications and content. I expect that 2016 will be the year when we start visiting exotic lands from the comfort of our offices and living rooms.

There are several technology developments which are bringing the future to us ahead of the Star Trek schedule. For starters, there is what is called “full-immersion virtual reality.” These are systems that take us out of the real world, into an entirely different digital realm. We hear stereo sounds and see panoramic displays that are so convincing that users lose track of time and space (they also, until very recently, suffered from serious nausea and motion sickness). Facebook’s Oculus Rift is the leading immersive virtual reality (VR) system but numerous others are either on the market or in the works.

Haptics Technology: Soon, We Might Be Able To ‘Feel’ Cyberspace

Posted by in categories: computing, electronics, mobile phones, neuroscience, virtual reality

Haptics is a growing field that aims to allow our bodies to control and ultimately ‘feel’ our virtual identity. Instead of using the theorized mechanism of a neural computer link, haptic tech attaches sensors and stimuli to our body. A report by research firm Markets and Markets thinks haptic technology, which could soon include something like a glove that let’s you move a hand in cyberspace, will be worth 30 billion by 2020.

Haptic technology, also known as kinesthetic communication, sounds like something out of science fiction. But products, like the vibrating cell phone, have been out for decades. And there’s more advanced systems on the way. That’s partly because of another hyped field: virtual reality. With pioneering virtual reality headsets like the Oculus Rift poised for release next year, the question becomes: How to make this experience even more immersive.

Simulation Shows Time Travel Is Possible

Posted by in categories: computing, particle physics, quantum physics, time travel

Australian scientists created a computer simulation in which quantum particles can move back in time. This might confirm the possibility of time travel on a quantum level, suggested in 1991. At the same time, the study revealed a number of effects which are considered impossible according to the standard quantum mechanics.

Using photons, physicists from the University of Queensland in Australia simulated time-traveling quantum particles. In particular, they studied the behavior of a single photon traveling back in time through a wormhole in space-time and interacting with itself. This time-traveling loop is called a closed timelike curve, i.e. a path followed by a particle which returns to its initial space-time point.

The physicists studied two possible scenarios for a time-traveling photon. In the first, the particle passes through a wormhole, moving back in time, and interacts with its older self. In the second scenario, the photon passes through normal space-time and interacts with another photon which is stuck in a closed timelike curve.

To infinity and beyond: Light goes infinitely fast with new on-chip material

Posted by in categories: computing, materials, nanotechnology

Electrons are so 20th century. In the 21st century, photonic devices, which use light to transport large amounts of information quickly, will enhance or even replace the electronic devices that are ubiquitous in our lives today. But there’s a step needed before optical connections can be integrated into telecommunications systems and computers: researchers need to make it easier to manipulate light at the nanoscale.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have done just that, designing the first on-chip metamaterial with a refractive index of zero, meaning that the phase of can travel infinitely fast.

This new metamaterial was developed in the lab of Eric Mazur, the Balkanski Professor of Physics and Applied Physics and Area Dean for Applied Physics at SEAS, and is described in the journal Nature Photonics.

Scientists paint quantum electronics with beams of light

Posted by in categories: computing, electronics, materials, quantum physics

A team of scientists from the University of Chicago and the Pennsylvania State University have accidentally discovered a new way of using light to draw and erase quantum-mechanical circuits in a unique class of materials called topological insulators.

In contrast to using advanced nanofabrication facilities based on chemical processing of materials, this flexible technique allows for rewritable ‘optical fabrication’ of devices. This finding is likely to spawn new developments in emerging technologies such as low-power electronics based on the spin of electrons or ultrafast quantum computers.

The research is published today in the American Association for the Advancement of Science’s new online journal Science Advances, where it is featured on the journal’s front page.
