Dexmo transfers your hand movements to the digital world.

Kickstarter over the years has harbored and successfully brought more ideas into the commercial industry unlike anything else. The Virtual reality head mounted display Oculus Rift is a good example that proves the point. Oculas Rift started of as a $2.4 million project on kickstarter in 2012 and now its a company worth $2 Billion.

But we are not talking about Kickstarter or Oculas Rift here, we are talking about another revolutionary idea in the Virtual reality scene, called the 'Dexmo'.

Dexmo is a hand wearable exoskeleton that input your hand movements into the digital world and outputs force feed back to your finger so you feel the object in the digital world.

Dexmo is a project developed by Dexta Robotics, a robotics start-up based in Shenzhen, China.

Well the technology is not something very new. We have had countless university and academic projects that are quite similar to this. However what sets this itself apart is the fact that its going to be affordable to buy and cheaper to build. Its designed for mass production, its not just a prototype its developed on principle of DFM (Designed-for-manufacturing).

Skully: The Helmet of the future

In recent times we find smartphone technology almost reaching a point where we have almost packed everything in a very small box package. The processing power of a computer right in the palm of your hand. Now the time has come when the same needs to really spread out into wearable technology. Google Glass and Smart watches are two such things that have already proved the concept. May be in a few years from now wearable electronics would be a thing of everyday use.

So if you drive a bike you know how difficult it gets to access your phone once you put the helmet on. Skully AR-1 is the answer to just that and a lot more. Imagine a helmet that brings all the features of a smartphone right in front of your eyes. And yes no compromise on safety.

StoreDot-nanodot battery technology can charge your smartphone in a matter of seconds

What if charging your smartphone battery from empty to full just takes 30-40 seconds of your life. That would be such an awesome thing right?

An Israel based company by the name StoreDot demonstrated a new battery technology that could revolutionize the entire portable electronics and electric vehicle technology for the better at the Microsoft’s Think Next symposium in Tel Aviv on 7th April.

How it works 

In a traditional battery the voltage is developed by a chemical reaction. The time needed to charge the battery is basically the time required to reverse the chemical reaction.

The new battery technology utilizes electrodes made with new materials and are called MFE- Multi Function Electrode. The electrode basically acts as a super-capacitor on one side (with very fast charging), and on the other is like a lithium electrode (with slow discharge). The electrolyte is modified with what are called Nanodots in order to make the multifunction electrode more effective.

Spike puts laser range finder technology in the back of a smartphone

If you have ever worked in the GIS industry; accurate, easy and portable data acquisitions system devices are the key forces that drive the industry. ikeGPS is a New Zealand based company that's been developing some really great portable GIS data acquisition hardware and software for quite some time now. Their flagship device called the 'ike' integrates a laser range finder, a camera, GPS and a 3D compass into a small portable package which made possible to measure the length or height of any geographic feature, just a matter of taking a few photographs and you have all the measurements in the palm of you hand.

With the new device called 'Spike' short for "Smart Phone ike" , the company has taken its reach to a whole new level. On the hardware side, Spike is basically a small device that piggy backs on a smartphone and converts it into a full blown accurate laser measurement device and a 3D modelling device.

AirMule takes UAS technology to a new dimension

UAS (Unmanned Aerial Systems) technology comes in all shapes and sizes these days. Although the bigger ones are mostly used by the armed forces for international reconnaissance and in some cases attack, like the Predator B.

A system developed by the Tactical Robotics LTD a subsidiary of the the Urban Aeronautics LTD based in Israel have developed a unique UAS system which due to its VTOL and and high maneuverability, can perform a multitude of tasks and could possibly take the capability of UAS to a totally new level in terms of both civilian and military use.

At first glance it looks something straight from a SciFi action movie. The Aircraft is only slightly larger than the size of a standard Hummer. The biggest advantage for this aircraft are the internal lift rotors (Enclosed in the body) which gives it the benefit of flying in mountainous and urban environments, conventional helicopters or other multirotor platforms have a risk in such environments due to their exposed rotors.

Heat Sink technology used for efficient cookware.

If you have ever looked into the insides of a Desktop computer you might have noticed a prominent fan placed over finned metal block mostly made out of aluminium. That's called a heat sink and its designed to take away all  the heat generated by the microprocessor. Without a proper heat sink the processor might just burn up or melt away. The heat sink basically spreads out the heat over a larger area thus dissipates heats in lesser time.

Physicist Lee Huang though just the opposite, how about using a heat sink to absorb more heat from a gas stove flame more efficiently? A normal cooking pot as you know has a smooth surface at the bottom. A lot of heat from the burner flame escapes from the sides ending up being uselessly lost to the surrounding. A seemingly simple but effective idea is to attached fins at the bottom/base of the cooking pot. This results in more heat being utilized for heating the content in the pot compared to that of a normal pot with a smooth bottom. This results in lesser cooking time resulting in saving time and money. A great solution for commercial and house hold applications. The finned pots end up being 30-50% more energy efficient then their smooth counterparts.

DALER: A drone that's capable of flying and crawling on the ground

Researchers at the Swiss Federal Institute of Technology have been doing some remarkable work when it comes to innovation in flying robots.

This time from the Swiss Federal Institute of Technology in Lausanne (EPFL), researchers at the Laboratory of Intelligent Systems have come up with an innovative concept of a flying platform that can not only fly but even crawl on the ground. The backronym 'DALER' stands for "Deployable Air Land Exploration Robot". Its actually named after the man behind the Project 'Ludovic Daler' a Ph.D candidate.

The project goes by the title 'Adaptive Morphology for Multi-Modal Locomotion' and is aimed at developing robots capable of multiple modes of locomotion. For task such as exploration, search-and-rescue, or monitoring of the environment autonomous or remotely operated robots are the obvious choice. But for these kind of tasks robots may have to deal with complex terrains, such as semi-collapsed buildings, deep caverns, or forests with a lot of vegetation. In general, flying robots are considered  most capable for the purpose. However for exploring areas close to the ground it is found that ground locomotion is more efficient than flying. Hence a robot with both capabilities is suited for the purpose.

Contour Crafting:The Future of Construction?

Hey guys your host Akib here, just been really busy these days, I haven't posted in a while. I will get back to posting about awesome stuff regularly in a couple of weeks. So this is just a quick post so you realize that the Blog is stills alive. I came across this awesome technology called "Counter Crafting". Though I would share with you guys.

So Counter Crafting is basically bringing 3D printing technology (Rapid Prototyping) to the Construction Industry. The brain child behind this technology is Mr. Behrokh Khoshnevis a professor of Industrial & Systems Engineering and Civil & Environmental Engineering, and is the Director of the Center for Rapid Automated Fabrication Technologies (CRAFT). He is also a Director of Manufacturing Engineering Graduate Program at the University of Southern California.

So getting back to Counter Crafting well, I would say is basically printing a house just like you would print a part with a 3D printer, only difference being the proportions of things and the materials used are big and its more complicated cause you have to install electrical, piping and stuff. The 3D Printer (Counter Crafting machine) can be assembled at site. It could be put on a truck and taken to any location and its not completely autonomous like a 3D printer. It  require assistance in building a complete residable home.
The concrete used for the process is different, its called fiber reinforced plastic.

Virginia Tech's Robotic Jelly Fish: Another way to spy

In the past few years the US armed forces and other US Government agencies have been spending a lot of their funds on funding and allotting their projects to Universities and technical  institutes across the United States. Most recent projects are robotic projects that mimic animals and can be used for potential surveillance and assistance to the armed forces both on and off the battlefield.

Here is another awesome potential spying/surveillance robot being developed by the Graduate students of Virginia Tech College of Engineering. This time its a Jelly Fish and its called 'Cryo'.

Click to see enlarged view

Cryo is basically a prototype robot that looks very much like a giant jelly fish. Its 5.7 feet wide (1.7 meters) and weighs in at 170 lbs (77kg) and its designed to be neutrally buoyant. The inspiration for the design is the 'Lion's mane jellyfish' also termed the 'Cyanea capillata' by biologist, that's were the name 'Cryo' comes from.

VelociRoACH: Robotic Cockroach (hexapedal millirobot)

The Pestilent Cockroach have been here on planet earth for millions of years, and part of the reason of their evolutionary success is the shear speed at which they move. Most of the times the best engineering solution for a problem is mimicking nature, but mimicking nature obviously is very difficult. However day by day year by year we are getting closer and closer to doing that, specifically when we talk about legged robots.

Mr.Duncan Haldane and his colleagues at the University of California, Berkeley (UC Berkely), have been studying the six-legged pests to improve their millirobots. The 'VelociRoACH' as its called is the fastest legged robot in the world at the scale, however the fastest legged robot title stays with the LS3 from Boston dynamics (The Cheetah Robot).

Taking about specifications and technical details. The VelociRoACH can move with a velocity of 2.7 m/s actually making it faster than a real cockroach which do a maximum 1.5 m/s.

The secret of the the velocity of the VelociroACH is in the shape of its legs. Shaped like a 'C' they provide the spring action need to propel the robot really fast and at the same time absorbing the impact of the legs hitting the ground almost 15 times a second. The legs are similar to that of the R-Hex from Bostan Dynamics but don't work in the same way. Its body has been fabricated out of a good type of cardboard. Although it can lift 4 times its own weight. It weighs a mere 30 grams and is 10 cm long. To keep it stable, it must have 3 of the six legs making contact with the ground all time.

Your smartphone is a Desktop too with Ubuntu OS for smartphones.

Today smartphones have become more powerful than ever before. We have smartphones which have high clock speed Quadcore processors, upto 2gigs of RAM and also a great deal of storage, well that's a lot of processing power in the palm of your hands. But all people end up doing with it hardly utilizes the full potential of the hardware they paid for. Practically  its just a waste of hardware resources. Although that's not the users fault, Its the industries fault, The top three smartphone operating systems, the Android from Google, iOS from Apple and Windows Phone from Microsoft also have a separate PC OS. Why didn't these IT giants never though of developing an OS that works for/on both the devices or rather, just getting a Smartphone to do the work of an entry level PC. 
Well Apple and Microsoft in the recent past made some effort and big talks about the Desktop-Mobile convergence but never made serious effort towards it, may be the industry was never ready enough for it cause they were already making good money by kinda fooling people.

That being said Ubuntu backed by Canonical may have set a spark to revolutionize the IT industry for good, by just doing that, Building an OS that works both on smartphones and PC, rather a smart phone that's also an efficient desktop computer when connected to a screen, keyboard and a Mouse. 

In a recent announcement Ubuntu backed by canonical announced a new smartphone OS that's just the same as the PC OS, just with a Mobile friendly interface. What that means is you can convert your smartphone into a PC by just connecting it to a Screen, keyboard and a Mouse. Ubuntu is already available for Android Smartphones with a Dual core processor for free. What that means is you can run the full PC Ubuntu OS on a compatible smartphone.

A Homemade Spacecraft (DIY Tech)

Hey guys your host Akib here, I came across this really interesting short documentary about how amateur Engineers and entrepreneurs Kristian von Bengston (worked at NASA) and Peter Madsenin in Denmark are working on a project to build a suborbital spacecraft to carry a human into space and then release a capsule to return the passenger back to safety.

The Team calls themselves Copenhagen Suborbitals, a not-for-profit  which started off  in 2008 and now comprises of  20 plus specialists determined to create the first homemade, manned spacecraft to go into suborbital flight.  The idea is to prove that fact that rocket technology is not something beyond the reach of a common individual. The rockets that are undergoing testing are made from off the shelf components that are easily available to anyone. The project is completely open sourced you can have all the access to information and designs if you want to create your very own spacecraft.

Hexacopter and hexapod union looks like a robotic insect

Hexacopter and Hexapod are amongst  the latest and the most popular remote control robotic toys out there. How about combining them together to create a new walking and flying-walking hybrid machine. I bet you never though of that before. That's what the guys at Mad Lab Industries (MLI for short) have come up with. MLI is a  fresh start up that sells robotic components online and on the side they do cool stuff too.

So the basic idea behind this unnamed project is to integrate a remote controlled Hexapod Robot with a remote controlled Hexacopter. With this idea, they received a PhantomX AX Hexapod kit from Trossen Robotics.

The PhantomX AX Hexapod

Now the integration wasn't an easy task, considering the fact that the PhantomX was originally designed to be tough and was quite heavy to be  taken to the air. So it had to undergo a lot of surgery, the frame originally made of ABS plastic parts had to be replaced with lighter carbon fiber parts. Despite the fact, it was still heavy for it to be taken in the air by a quadcopter. Rather it needed a Hexacopter which has a much greater lifting force and was much stable than a quadcopter. A quadcoptor would have been cheaper considering the fact that it would have reduced the cost of 2 BLDC motors and ESC (Electronic Speed Controller).

MSI N550 GTX-TI unboxing/review on Intel Pentium 4 PC

Hey guys this is the first ever GPU unboxing review on Tech Center, I m not a PRO. at reviewing graphics cards, so please bear with me. I would like to tell you first hand that this is not a GPU review that you might find all across the internet its more of a GPU review on an old desktop computer.

My desktop computer is now over 6 years old and I really needed to upgrade it to gain some performance improvements. My desktop wasn't even able to play HD videos smoothly with the age old on-board graphics. With my tight budget, I did not go for the processor and motherboard upgrade, cause that would be like buying a new computer that would end up being only a little better than the existing one.

Keeping in mind that I would buy a new computer in like one year, I had to go for a graphics card that would not only fit my budget but; improve my existing machine and also be useful in the new computer that i plan to buy a year later. So after quite a bit of research and looking at benchmark results online I went for  the MSI Nvidia N550GTX-TI Cyclone II (1GB DDR5).

Lewis Hamilton burns some rubber on the streets of Mumbai.

Formula 1 McLaren driver Lewis Hamilton was in Mumbai this past Sunday night at Bandra-Kurla Complex. The run up was flagged off by Maharashtra Chief Minister Prithviraj Chavan in the presence of Public Works Department and Tourism Minister Chhagan Bhujbal, among other dignitaries.

With the Singapore Grand Prix just a week ahead, Lewis Hamilton made this skilful burnout in the  Vodafone McLaren Mercedes MP4-27 race car. Lewis Hamilton told that he is really looking forward for the Indian Grand Prix scheduled on 26-28 October later this year.

My cousin brother Rahil was able to capture the run up and burnout up close. Probably the best amateur footage available on YouTube.

DARPA's Cheetah Robot and the LS3 taking quadruped robot tech to new highs

DARPA in collaboration with Boston Dynamics has been brewing up some really awesome legged robot technology over the past few years. The various legged robot projects have been under constant update and improvement over the years. The list of the state of the art legged robots from Boston Dynamics includes the The Big Dog, Cheetah, Petman and the latest of the pack, the LS3. Each robots have been designed for a own unique purpose and have significant differences.

The latest updates however are from the Cheetah and the LS3.

The Cheetah

The Cheetah has been under development since 1989 under MIT and later under Boston Dynamics. It has been developed and funded under DARPA's Maximum Mobility and Manipulation (M3) program. A recent video update on YouTube shows The Cheetah running at 28.3 mph (45.5 km/h), breaking it previous record of 27.78 mph (44.7 km/h) which it achieved back in 2009. This makes it 0.5 mph faster than Usain Bolt.

Now that being said, The Cheetah has a lot of advantages over Usain Bolt, It runs on a high speed treadmill; plus, it is powered by an off board hydraulic pump and uses a boom-like device to keep it running in the center of the treadmill. Overall, significant improvements for the speeds have been made in the algorithms and a more powerful pump have been added. Although Boston Dynamics plans to test a free running Cheetah in the open environment by next year.

Not much details about the technology have been made public.

A Solar- powered system that's a Reverse air-conditioner to develop power for Developing world.

In the developing world, electricity and other resources necessary to run clinics are difficult to achieve and many a times costly to produce. In many African countries electricity from the grid is very inconsistent and unavailable in rural parts. So medical centres and clinics in these areas rely on Diesel generators or Photovoltaic solar cells for power, now these are costly propositions and require recurring cost of fuel and maintenance. Also places in Africa that fall in the temperate regions face very cold winters and Hot water becomes a necessity. Health worker avoid washing hands as the water supply gets very cold thus creating unhygienic conditions. 

A startup by the name STG (Solar Turbine Group) international established by alumni students of MIT have come up with a seemingly effective solution to the problem. The Technology is called Solar ORC and is somewhat similar to one those Concentrated solar power systems. It utilizes parabolic mirror reflectors that look like troughs. At the centre line of the these troughs lies a metal pipe which carries a HTF (Heat transfer fluid) inside. Now this HTF absorbs the heat from the concentrated sunlight and this results in raising the temperature of the HTF upto 160 degree Celsius.

This heated HTF now enters into an ORC unit/ORC engine, it works on an Organic Rankine cycle (Its a Rankine cycle except it works on Refrigerant rather than water as working fluid) . It works like a reversed air conditioning unit. Instead of utilizing electricity to cool the air and throw hot air outside. It actually uses the hot HTF and the cold ambient air to produces mechanical work which is converted into electricity.

The key element of the system a device called a scroll expander, which convert the heat difference into mechanical power is described in a paper to be published in the ASME Journal of Engineering for Gas Turbines and Power.

3D printing and robotic technology helping doctors help patients

3D printing technology has really given manufacturing a new dimension. Specially if you think in terms of  manufacturing small intricate parts that might be useful in small robotic devices. Although personally I never thought that one day 3D printing technology would help doctors help patients until, I came across this story.

2 year old Emma suffers from a rare congenital disorder called Arthrogryposis that is characterized by multiple joint contractures (shortening and hardening of muscles) and can include muscle weakness and fibrosis. Emma was born with her legs folded up by her ears and her shoulders turned in. As a result she could not move her arms and lift things like normal 2 year olds would.

So the solution was to give her arms some external help by an exoskeleton. Researchers at a Delaware hospital 3D printed a durable custom device with the tiny, lightweight custom parts Emma needed. She calls them her “magic arms.” Now this allows her to freely move her hands around and pick up objects.

Lockheed in Collaboration with LaserMotive Tests UAVs With Laser Power Beaming

The quest to transmit power without wires has been something people have been working on since centuries and obviously it not science fiction anymore, people have come up with different ways to transmit power wirelessly. We wrote about Wirticity back in 2010 which gained a lot of media attention back then.

Back in 2009 a Seattle-based company by the name 'LaserMotive' specializing in laser power beaming proved to be the only successful entrant and winner of the NASA-sponsored Power Beaming Challenge. 

The idea of laser power is pretty simple. Just like a photovoltaic cell (solar cell) produces electricity from sun light, Laser power beaming acts in the same way. A powerful laser beam is used to carry energy over distances; this energy in the form of light and heat can be converted into electricity by using photovoltaic cells. This enables to transfer power wirelessly over distances and can be consider a more practical efficient and cost effective way compared to other wireless power transmission methods available. To get into the details you can check out this Laser power beaming fact sheet.

So now that we know about laser power beaming, the idea can be used for a wide variety of applications, only your imagination is the limit. Although there are a lot of safety and efficiency factors involved with makes it difficult to use over existing electric power grid, we wont get into that in this post. You can always leave a question or opinion in the comments.

Now in the modern warfare era of Drones, UAVs and UAS (unmanned ariel systems), endurance is one of the major challenges faced by UAV designers and developers. Battery based UAVs are silent but poor at endurance. Conventional fuel based UAVs have better endurance but they are very noisy and are difficult to use where you require to fly at low altitudes and small areas. So the application of laser power beaming seems to be the best solution. 

Miniand Tech its MiniX TV Box and Mini PC devices.

In the past we have covered some really interesting and cost effective mini computers and plug computer devices. Here is a list if you are interested. 

An Australia/China based company by the name "Miniand Tech" is selling two interesting mini computer devices. One is the MK802 Mini PC and the other is the MiniX TV Box H24 which can be rather compared to a TV box like Google TV.

The MK802 Mini PC.

The MK802 Mini PC is a kind of plug computer with very small dimensions i.e. 88.5 x 35 x 13.4 mm weighs in at 300 grams. The device has 2 USB ports one Full size standard USB and the other seems to be a micro USB. The best part is the standard USB could be used to connect plug and play devices like a wireless mouse and keyboard. It runs on the latest Android 4.0 OS ans supports most application and features supported by a top notch Android 4.0 smartphone. Its powered by an External adapter 5V/2A output, 110-240V input.

What that means you could even run it from an external battery if you get the right voltage and amps. Although i wont recommend you to do that if you don't know anything about electronics.
