An Artificial Iris Could Let Cameras React To Light Like Our Eyes do

While the pupil may be the opening in the eye that lets light through to the retina, the iris is the tissue that opens and closes to determine the size of the pupil.

Although mechanical irises are already a standard feature in cameras, scientists from Finland and Poland have recently created an autonomous artificial iris that’s much more similar to those found in the eye. It may even eventually be able to replace damaged or defective ones.

he contact lens-like device was created by researchers from Finland’s Tampere University of Technology, along with Poland’s University of Warsaw and Wrocław Medical University.




It’s made from a polymer (a liquid crystal elastomer) that expands when exposed to light, then shrinks back when the light is lessened. This causes an opening in the middle to get smaller or larger, depending on the light levels.

In this way, it works very much like a natural iris. Unlike automatic irises in cameras, it requires no power source or external light detection system.

With an “eye” towards one being able to use it as an optical implant, the scientists are now adapting it to work in an aqueous environment. They’re also working at increasing its sensitivity, so that its opening and closing are triggered by smaller changes in the amount of incoming light.

The research is being led by Tampere’s Prof. Arri Priimägi, and was recently described in a paper published in the journal Advanced Materials.

This Is A Bio Inspired 3D Printed Spider Octopod Robot

T8 robot

The T8 octopod robot is modeled after a real tarantula, and the way it moves is startlingly realistic an effect that’s amplified by its high-resolution 3D-printed shell, which conceals the robotics inside

Each T8 moves with the help of 26 Hitec HS-35HD servo motors. Three in each leg and two to move the body and is pre-programmed using Robugtix’s Bigfoot Inverse Kinematics Engine, which handles the calculations for factors like trajectory planning and gait and motor control.




All the operator has to do is press buttons on the controller, which communicates with the robot via an XBee radio module.

It’s an impressively spooky little critter, though. Check it out in the video below.

Light Up Your Day With These LED Flashlight With The Size Of A Match

MBI Matchbox

Over at Tokyo-based MBI Matchbook they created the world’s tiniest LED flashlights that look very much like real matches – they are small enough to always keep them in your pocket or a wallet in case of emergency.

8 miniature flashlights housed in a convenient matchbook style holder are waterproof and fully submersible, meaning they’ll work just fine even if you dive with them in a pool.



If you aren’t a fan of a red LED tint, you can also opt for a white or a green one. Each of the flashlights has a run time of approximately 8 hours, so if you go out camping, they’ll be your best buddies for about 64 hours in total.

The tiny flashlight uses a lithium tube type battery, which has 3mm in diameter and is approximately 20mm long. At the bottom of the battery there is a 3mmx3mm neodymium magnet, coated with a plastic-rubber sheath to ensure additional protection.

This Mechanical Instructor Can Guide And Teach Anyone How To Dance

waltz robot

Researchers have developed a waltzing robot that can teach people how to dance. This robot can take the lead, allowing the robot to teach dance sequences.

While the system has been developed for dancing, it could also have other applications including physical rehabilitation and sports training.

The system adjusts its difficulty mode based on the user’s number of previous practices and performance history.




The bot, which stands 1.8 meters tall (5 feet 9 inches), was designed by researchers at Tohoku University in Japan.

According to the authors of the study, the bot its designed for contact with adults with heights ranging from 1.5 meters (4 feet 9 inches) to 1.9 meters (6 feet two inches) meters tall.

It has a force sensor and two laser rangefinders to track movements, which are compared against motion-capture data originally recorded from professional dancers.

This App Will Let You Call An Uber Just by Clicking Your Heels

ruby heels

Every little girl who watched The Wizard of Oz thought one thing: I want those ruby slippers. They were so beautiful, sparkly, colorful, and bright, like Christmas molded into a low heel and round toe.

And the idea that you could get home with three ladylike clicks of the heel warmed our lazy little hearts. Certainly a lot more glamorous than hailing down a cab like a wild banshee or digging through the depths of your bag for your phone to request an Uber.



Well, thanks to technology, it seems that perhaps some dreams really do come true. A creative agency called iStrategyLabs just unveiled the aptly named Dorothy, a device that will give you powers much like our favorite stranded Kansan.

All you have to do is slip “the ruby” a small Bluetooth-enabled micro-controller into your shoe, click your heels three times, and wait for your Uber to arrive.

An Army Of These Robotic Turtles Might Help Rid The World Of Landmines

robot turtle

Detecting landmines is no easy task, but thankfully, a team of researchers at the Arizona State University is developing a fleet of robotic turtles to locate (and detonate) them in the desert.

These robot turtles could safely tag landmines without risking human lives.

Every year, an estimated 15,000 to 20,000 people are killed or maimed by landmines, according to UNICEF. Militaries around the globe currently use an array of both low and high-tech approaches to remove them from metal detectors and trained bomb-sniffing dogs.




Unlike bomb-sniffing dogs, these robotic turtles have the ability to work independently in the field. Seeing as the current prototypes are intended for use all over the globe, researchers are programming them with algorithms that allow them to react and adjust to different environment.

A Cardboard Bicycle Is Now A Reality

Israeli cycling enthusiast Izhar Gafni is the one behind this cardboard bicycle, where it is not only highly affordable at just $10, it is also eco-friendly and lightweight.

The pieces of cardboard have been painstakingly bent and folded into what initially resembles that of a shipping package on wheels.

Once done, all of it is dunked into a bit of resin, before a layer of pearly paint is added, and you end up with beautiful looking bicycle, albeit at a relatively cheap price.

Since it is made out of cardboard, the coat of resin has a special role to play. It makes the entire cardboard bits and pieces waterproof.

So that riders are able to glide through puddles or a rain storm without having your ride all apart or unable to take your weight due to the sogginess.

There is also an attachable electric motor accessory just in case you need to have that extra boost in speed.
