3D Printing Technology to Create Shock Absorbing Skin

3D Printing Technology – Custom Shock Absorbing Dampers/Skins

Robots have a tendency to break and often it could be due to improper padding to protect them. However scientists of Computer Science and Artificial Intelligence Laboratory at MIT – CSAIL have come up with a new technique for 3D printing soft materials which tends to make robots safer as well as more accurate in their movements.

For instance, after 3-D printing a cube robot that moves on bouncing, the researchers prepared it with shock-absorbing `skins’ which utilises only about 1/250 of the amount of energy it transfers to the ground. The 3-D printing technology had been utilised to create custom shock absorbing dampers or skins in order to safeguard drones and robots.

Known as the `programmable viscoelastic material – PVM technique, the printing method of MIT provides object with the accurate stiffness or elasticity they may need. According to the MIT, the inspiration for the project had come from a predicament. Common damper resources usually tend to have solid as well as liquid assets which are made from compact, cheap and readily found items like rubber or plastic, but these seem difficult to customize. They cannot be created beyond specific sizes and dampening levels which are already in place.

Cube Shaped Robot – TangoBlack

This issue had been resolved by the team by utilising 3D printing technology in creating a bouncing cube shaped robot from a solid, a liquid together with a flexible rubber type material known as TangoBlack+. Besides absorbing shock, the cube robot is said to be capable of landing more accurately in consideration of its skin.Daniela Rus, Director of CSAIL who had supervised the project and co-wrote a related paper, commented that reduction tends to make the difference in preventing a rotor from breaking of a drone or a sensor from cracking when it tends to hit the floor.

 These materials permit 3-D print robots with visco-elastic properties which can be recorded by the user at print-time as part of the process of fabrication. MIT informed that the technology could be utilised in expanding the lifespan of delivery drones such as the ones that have been created by Amazon and Google. It could also be engaged on a more practical level for performing tasks like helping to protect phone or cushioning heads in helmets and the feet in shoes.

Skins Enables Robot to Land Four Times More Accurately

The skins also enable the robot to land almost four times more accurately recommending that related shock absorbers can be utilised in helping in lengthening the lifespan of delivery drones.The new paper was presented at IEEE/RSJ International Conference on Intelligent Robots and Systems in Korea written by Rus together with three postdocs with lead authors Robert MacCurdy together with Jeffrey Lipton as well as third author Shuguang LiThe cube robot comprises of a rigid body, accompanied by two motors, a microcontroller, battery together with inertial measurement unit sensors.

Four layers of looped metal strip seem to serve as springs which tend to propel the cube. Hod Lipson, professor of engineering at Columbia University and co-author of `Fabricated: The New World of 3-D Printing’, states that by combining multiple materials in achieving properties which are beyond the range of the base material, this work drives the envelope of what’s probable to print. On top of that being able to do this in a single print-job, raises the bar for additive manufacturing’.

If the US Hacks Russia for Revenge, That Could Lead to Cyberwar

After Russia took claim of a recent upon the US government in the cyber field CIA wishes to send a message back by indulging in similar response. Russian hackers brought massive cyber attacks upon the US and try to bring huge interference during the US election through state sponsorship. CIA has a plan to bring the offensive back to the Russian by launching similar attacks which will only help worsening the relationship between the two countries.

Just last week a report was released by NBC News where it was specifically stated that CIA is actively working on the blueprints to launch one of the most covert cyber operation against Russia in near future. Few experts has suggested that CIA would be working towards leaking the letters and documents related to Vladimir in the similar fashion as Russians has released the documents related to the Clinton campaign and the Democratic National Committee.

Documents collected to be utilized during cyber attack

Retired security personnel has stated that over the years CIA has accumulated a wide number of documents and filed which can create trouble for the Russian and most importantly for Vladimir Putin. These documents basically deal with notorious dealing of the Putin and his associates in the last decade and beyond.

Ex-NSA Chief Michael Hayden has even went ahead to say that hacking foreign governments as well as political happens to be the past time of the CIA. Currently the relationship and atmosphere surrounding these two countries has become quite similar to the Cold War era but instead of a nuclear war threat of an impending cyber war looms in the air. Obama is going out of the office in November but even that has not stopped him from criticizing Putin in this regard.

It might even happen that all these theories about CIA possessing a truckload of information on Putin is simply a story to scare off Russians from causing anymore undue damage in the cyber field. If CIA plans are real then how useful will it be against Russia is yet to be asserted. A number of security experts has stated simply releasing damaging documents against Putin will not have any impact among the Russian government though his image might take a hit globally but nothing worthwhile can come out of it in the long run.

A warning for impending cyber war

US politicians are highly susceptible to the public pressure which can even spoil their future and political career if any documents are found against them. On other Putin isn’t much susceptible to such thing but Russian can utilize its highly robust internet surveillance plan to launch attack upon the US in the cyber field if it ever feel threatened then it will go on full-fledged cyber war against US.

The international paradigms changes just a few years ago the greatest threat to US cyber security was China. China has been accused of hacking into and tens of millions of US citizen’s security review files right from the US government online databases which tend to go decades back.

New Security Method Sends Codes through Your BODY

Low Frequency Transmission

Wi-Fi together with Bluetooth are said to be areas for hackers since these techniques enables easy and anonymous stealing of passwords. In order to stall these activities, a group of students have come out with a system which tends to utilise low frequency transmission to send passwords via the human body.

On reversing the same system utilised by fingerprint sensors, they have achieved a method to generate wireless data transmission between the smartphones and the other devices. Senior author Shyam Gollakota, assistant professor of computer science and engineering at the University of Washington (UW) stated that till now, fingerprint sensors had been utilised as input devices.

He further added that for the first time that fingerprint sensors can be re-purposed to send out information that is confined to the body. Fingerprint sensors had been designed for the purpose of receiving data about one’s finger which is utilised to authenticate identity. However, the UW team inverted the procedurealtering the technology into an output which tends to push the data comprising of a password or access code from the smartphone to the other device.

Works in Various Postures

Co-lead author Mehrdad Hessar, a UW electrical engineering doctoral student explain that if one intends to open a door utilising an electronic smart lock he can touch the doorknob and touch the fingerprint sensor on the phone and transmit secret credentials via the body to open the door without leaking the personal information over the air.

In experiments, the researchers had demonstrated this system utilising the Touch ID sensor of an iPhone 5s and iPhone 6s, together with the trackpad of a Lenovo laptop as well as other fingerprint scanners. During the evaluation, around ten subjects had been utilised and varied in height, weight and body type, which were capable of generating usable on-body transmissions.

The team also envisaged positive results even when the participants were moving, like walking around or moving their arms. Co-lead author, Vikram Iyer, a UW electrical engineering doctoral student commented that they had shown that it works in various postures like sitting, standing and sleeping. Good strong signal is obtained throughout the body. The receivers could be anywhere, either on the chest, hands or legs and still tends to function.

Generate Low Frequency

This ground-breaking project began by analysing smartphone sensors by the team in order to detect which one tends to generate low-frequency less than 30 megahertz and travels well through the body though does not propagate over the air. It was only fingerprint sensors and touchpads which were found to meet up with all these requirements.

These methods tend to generate signals in the 2 to 10 megahertz range and transfers energy in an electric network to sense where in the space your finger would be. Moreover, it also identifies the ridges as well as valley which form the unique fingerprint patterns. The procedure which the UW utilised is a sequence of finger scans to encode and to transmit data.

With a finger scan it tends to correlate to a 1-bit of digital data and without the scan correlates to a 0-bit. The team had also succeeded in bit rates of 50 bits per second on laptop touchpads and 25 bits per second with fingerprint sensors which were adequately fast in sending a simple password or numerical code through the body and to a receiver in seconds.

This Year’s Paris Auto Show is Très Électrisant

Electric Car Market – Tesla Motors

The electric car market is dominated by Tesla Motors with regards to the attention the small-scale car builder tends to get. In a world of contraction emission criteria as well as city-wide prohibitions of internal combustion engines, it has been jointly decided that the electric cars seems to be the solution. This has been obvious during the recent Paris Auto Show.

The Mondial de l’Automobile seems to have the usual extreme French concepts though is close-to-production EVs like those of Volkswagen, Mercedes and Porsche.Mercedes-Benz and Volkswagen AG have been leading enormous changes in the approach to electric cars in the auto industry with ambitious intentions focused in ending the indifference of consumer for battery powered vehicles.

The automakers from General Motors Co.’s Opel to Renault SA, at the Paris Motor Show had been announcing their contributions on latest electric car. In contrast to the earlier years where the focus was on viability, the exhibition this year had been focused in generating mass appeal addressing concerns regarding range as well as widening the selection of options.

The I.D. concept vehicle had been unveiled by Volkswagen that had been set to create a sensation in the market by 2020. Moreover it could drive almost double as far as the future Model 3 sedan on a charge of Tesla Motors Inc.

Car - a Revolutionary

Though only a model, the VW hatchback would kick off the roll-out of 30 battery powered car in the near future since the German manufacturer intends to alter an image tarnished by the emission-cheating outrage and Volkswagen seems to have high hopes for the vehicle.

Head of the VW brand, Herbert Diess commented in a Bloomberg TV interview with Caroline Hyde, that this car would possibly be revolutionary. It would possibly have the same importance which the Beetle had in its age or the Golf and the next generation will be I.D.Mercedes on the other hand is being likewise aggressive.

Earlier depending on converting the present model to electric, the Daimler AG unit intends to now introduce almost 10 new battery-powered vehicles. The vehicles together with the related technology like the charging boxes and energy storage would be promotedunder the EQ panel, providing more visibility.

Meeting Restricted Emissions Standards

Chief Executive Officer of Daimler, Dieter Zetsche had mentioned in Paris that they are now flipping the switch and are ready for the launch of an electric product offensive which would be covering all vehicle segments from the compact to the luxury class.

In particular, European manufacturers seem to be slow in developing a rational electric car strategy with the exception of BMW AG, having two diverse cars built around a carbon-fibre architecture which seems to be on the road already. The appeal of electric cars has been widened with Tesla’s success with the buyers in the U.S. and Norway, though the U.S. manufacturer has faltered while seeking to lift output which its well-established European opponents could have less trouble in achieving.

Though the cost of batteries seemed to have dropped in making electric cars reasonably priced, the turnabout of the industry also comes from stress in meeting the restricted emissions standards. The European Union is in search of efficiency progress in the next five years which would be almost double the gains since 2010.

What is a DDoS attack? And could my computer be a weapon?

Anonymous is a notorious hackers group which has recently caused a massive cyber-attack on a web hosting service provider which offers hosting services to a number of business site in the world. Anonymous has issued a chilling warning about an impending cyber-attack through Distributed Denial of Service through its Twitter handle. DDoS attack are the most favored and common way of launching attack on any website wherein the site is overloaded with service request to such a point wherein it ceases to function.

Its servers buckled down under the pressure and the site goes offline for the users which results in millions of dollars in loss for the business house which operates the site. Furthermore coming from such attack isn’t an easier affair as it requires a lot of time, money and expertise to bring site back to its full functionality coupled with latest security measures.

Quite recently a number of major banks and popular sites & services have taken a hit by Anonymous attack which includes Twitter, Netflix and Spotify. Anonymous has not stated at which establishment or corporate sector or even the site they will be attacking next with their DDoS attack.
Anonymous hackers group has shades of white and black

Over the years Anonymous has been able to get favorable support from the people all round the world through their good work. Anonymous hackers group has launched massive attacks against the Islamic State in the past which has left the notorious terrorist organization in online turmoil.

They launched a DDoS attack against the Australian PM website when Australia was thinking about block the malicious content on the website which was direct attack to user’s online freedom. In similar fashion Anonymous took down as many as eight Tunisian government website with DDoS attacks when they found that it was subduing the freedom of the speech of the people.

Quite recently it launched a massive cyber attack against a little webs hosting service provider which helped in bringing down the Twitter, Netflix, Spotify among others. Anonymous can easily be described as a group of activists which came together in 2003. Since November 2015 when Paris attacks took place Anonymous has declared a cyber war on the ISIS. Most of the time Anonymous takes down the website offline in order to bring focus towards the social justice or censorship present in the nation.

Huge number of popular website goes down

A number of users on global scale ranging from US to European regions are reported that they were inaccessible to the major popular site which includes, AirBnB, Pinterest, PayPal as well as PlayStation’s online service.

This particular DDoS attack was targeted on the Dyn which is a little known hosting service provider for a wide number of popular high traffic websites. Currently US authorities are investing this attack while Dyn has made a statement where it accepted attack on its servers. Dyn is working towards mitigating and monitoring the attack against its Managed DNS infrastructure.
