Different Types of Drones.

08:06
          What is Drones?
          Unmanned aerial vehicles (UAVS), also known as drones, are aircraft either controlled by person from the ground or increasingly, autonomously following a pre-programmed mission.  While there are dozens of different types of drones, they basically fall into two categories: those that are used for reconnaissance and surveillance purposes and those that are armed with missiles and bombs.
       The use of drones has grown in last few years. Because of small size and ability to fly without an on-board pilot  and also it can be used for more than one application made it more popular.
See the top ten uses of drones.

Top Ten Uses of Drone and Quadcopter.

01:35

         The Drone or Quad copter officially called unmanned air vehicles (UAVs) is the new trending technology in tech field. Because of small size and ability to fly without an on-board pilot  and also it can be used for more than one application made it more popular.
        Now the uses of drone has been increased in many field such as,
  •   Search and Rescue.
  •   Public Service.
  •   Inspections.
  •   Security.
  •   Surveillance.
  •   Wild Life Protection.
  •   Science and Research.
  •   Traffic control.
  •   Aerial Video and Photography.
  •   Surveying.

Best in Different Types of Robots.

04:02
Now the scientists have achieved new and improved stage in robotics.The robots are coming and their presence are dramatically impacting in human life. Robotics is highly advanced technology that strives to robots for various application such as in military as well as for entertainment.

Different type of robots.

         In robotics there are different type of robots.The three main types are humanoid robots, autonomous robots and entertainment robots. Here is the some of best robots of above mentioned types.

 1) QRIO (quest for curiosity)


















 2) HRP







3) ASIMO (Advanced Step in Innovative Mobility)


 



4) PARO







5) PaPeRo (Partner-type Personal Robot)







6) AIBO (Artificial Intelligent Robot)

Invisibility - The Invisibility Become Reality Very Soon.

01:35

          





       
         Scientist has discovered the devices which are able to bend the light around three dimensional objects making them to “disappear”.
“Invisiblity” has not remained a thing of science fiction movie or story. Imagine when one will be able to disappear in the air and no one is able to see him like the Harry Potter invisibility Cloak. 

          The materials used for the invisibility devices are artificially designed and research are being carried out since than the idea strike the mind of thinkers of invisibility. The breakthrough could lead to systems for rendering anything from people to large objects, invisible to the eye – although this is still years off. The day is not for away when we have invisibility cloak large enough to hide us.



       






         The things which our eyes are not able to see are considered as “ Invisible”. Light is neither absorbed nor reflected by the objects, passing like water flowing around a rock. As a result, only the light from behind the objects can be seen. The devices which are going to make us hide are invisibility devices. Researchers at the University of California at Berkeley, whose work is funded by the American military, have engineered materials that can control 

       Nature, are expected to report the results in near future. . The concept of invisibility would involve surrounding the object by a "metamaterial" . Meta-material is a type of composite material that has unusual electromagnetic properties. According to the researchers, light rays incident on the material would be bent around the object, only to emerge on the other side in exactly the same direction as they began. Although the work is only theoretical, the researchers reckon that materials invisible to radio waves could be produced within five years.

How to be Untraceable on Internet. Get Anonymity on Internet

23:13
   
      The government agencies, and hacker are checking on your online presence and activities every day. Now the internet privacy is a question mark. It doesn't promise a 100% anonymity. But these tricks can make a bit harder to them than usual. To get untraceable on internet there are some ways .

    Virtual Private Network (VPN).

    What  is  a  VPN?

      A VPN is an  acronym for virtual private network. A Virtual Private Network connects the components of one network to another. Using Public Network or Local Area Network. It is safely and securely transfers information from one network to another system.
      VPNs will encrypt your real IP from website, people and it will keep your connection encrypted so you won't be able to get traced.
      There are many paid and free VPNs available online. In my point of view paid VPNs are more secure than free and keeps no logs. With no logs VPNs there's no record of your IP address, downloads, web traffic or browsing. So in effect there's no information there to be give up. Your anonymity is safe.

  Some of paid VPNs are,

          *  Blackshades VPN
         *  nVpn
         *  IPredator

Free VPNs are,

        *  CyberGhost VPN
       *  ProXPN VPN
       *  OpenVPN
       *  Hot Spot Shield

Hide IP Address Using Proxy Server.

      Yous Computer's IP address gives up an amount of your information to anyone who wants to look. In some cases it can reveal your latitude and longitude of your location, as well as what ISP and type of browser you use.
    The most common methods to hide IP address is using Proxy Server

What is a Proxy Server?

        A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server, then requests a connection, file, or other resource available on a different server. The proxy provides the resource either by connecting to the specified server or by serving it from a cache. In some cases, the proxy may alter the client's request or the server's response for various purposes.

Virtual Reality. A virtual World in Future

04:22

            Virtual Reality (VR), sometimes called Virtual Environments (VE) has got much attention in the last few years. The Virtual Reality uses a huge number of technologies to produce a Virtual world so that a user can interact and manipulate with the virtual objects in the so produced Virtual Worlds. With the aid of some specially developed gadgets like a Head Mounted Display, Electronic Glove and Mechanical armatures that fit the human organs we can immerse the human into the Virtual world. The simulation technique is combined with the motion of the human to produce the output that what human expects for. If a person in a Virtual world looks at a particular object then he has to get the feeling that he is actually looking at that object and he should also get the feeling of the sounds that come from that object.

            Virtual Reality is a way for humans to visualise, manipulate and interact with computers and extremely complex data.
            Here the word visualisation refers to the computer-generated outputs such as computer graphics, simulations, and other such as the CAD models. Here the outputs may be animations that can be controlled easily by scripts. Here the human can directly interact and manipulate with these animations. The most difficult thing in the Virtual Reality is to produce the interaction between Virtual world and the human but not the production of the Virtual world. The type of Virtual Reality in which the human is actually immersed into the Virtual world is called the immersive Virtual Reality. In such a type of Virtual Reality the human is completely isolated from the outside world and he is placed an entirely computer generated world.
