Brain Computer Interface (BCI)

Image
  Introduction To Brain Computer Interface (BCI): Brain-computer interface (BCI) is a collaboration between a brain and a device that enables signals from the brain to direct some external activity, such as control of a cursor or a prosthetic limb the interface enables the direct communications pathway between the brain and object to be controlled. Technology has made it possible to make use of computers as a replacement for the brain. Many kinds of research are going on to reduce the human work. The world is marching towards the automation in order to reduce the complexity in the work, speed up the process and at the same time to provide a relaxed life to all mankind. Some of the technologies involving human brain are blue brain project , the blue eyes technologies . A Brain-computer interface (BCI) provides a new communication channel between the human brain and the computer. The 100 billion neurons communicate via minute electro-chemical impulses, shifting patterns sparking lik

Humanoid Robots

                                         Humanoid Robots A Humanoid may be defined as something that resembles or looks like a human and having characteristics like opposable thumb, ability to walk in upright position etc. These robots are called Humanoid Robots or may be simply “Humanoids”. A humanoid robot is a robot which has a similar shape as that of a human body. In general, a humanoid robot has a torso, a head, two arms, and two legs. These robots vary depending upon the material they are made of and the design. Generally, humanoid robots come in three variations small sized humanoids, medium sized humanoids, and large sized Humanoids. Some humanoids may also have a face, eyes, mouth and are categorized as male humanoids and female humanoids. The purpose of such robots may vary depending upon its bio-mechanics, functional capacity, production cost and complexity involved.  Features of Humanoid Robots : The characteristics features of Humanoid includes: •       Self-mainten

Li-Fi Technology

  Introduction To Li-Fi Technology: Unlike Wi-Fi that uses radio wave, Li-Fi is a wireless communication technology that uses light waves to provide an internet connection. And instead of Wi-Fi modems, Li-Fi would use transceiver-fitted LED lamps that can light a room as well as transmit and receive information. Since simple light bulbs are used, there can technically be any number of access points. This technology uses a part of the electromagnetic spectrum that is still not greatly utilized- The Visible Spectrum. It is possible to encode data in the light by varying the rate at which the LEDs flicker on and off to give different strings of 1s and 0s. The LED intensity is modulated so rapidly that human eyes cannot notice, so the output appears constant. More sophisticated techniques could dramatically increase VLC (Visible Light Communication) data rates. Teams at the University of Oxford and the University of Edinburgh are focusing on parallel data transmission using arrays of
