A robotic pet is an artificially intelligent machine made in the image of an animal commonly kept as a pet. So far, these animals include dogs, cats, rabbits, and birds. Some people even treat these robots as actual pets. Robotic pets may also include things not normally considered pets, like Pleo, a simulation robotic dinosaur. Some people treatdomestic robots such as the Roomba as pets. They keep elderly people from being depressed and also keep them active.
Nanotechnology ("nanotech") is the manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications (including industrial and military), governments haveINVESTED billions of dollars in nanotechnology research. Until 2012, through its National Nanotechnology Initiative, the USA has invested 3.7 billion dollars, the European Union has invested 1.2 billion and Japan 750 million dollars.
Scientists currently debate the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials energy production, and consumer products. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.
A cyborg (short for "cyberneticorganism") is a theoretical or fictional being with both organic and biomechatronic parts. The term was coined in 1960 by Manfred Clynes and Nathan S. Kline.[1] D. S. Halacy's Cyborg: Evolution of the Superman in 1965 featured an introduction which spoke of a "new frontier" that was "not merely space, but more profoundly the relationship between 'inner space' to 'outer space' – a bridge...between mind and matter."
The term cyborg is not the same thing as bionic and often applied to an organism that has restored function or enhanced abilities due to the integration of some artificial component or technology that relies on some sort of feedback. While cyborgs are commonly thought of as mammals, they might also conceivably be any kind of organism and the term "Cybernetic organism" has been applied to networks, such as road systems, corporations and governments, which have been classed as such. The term can also apply to micro-organisms which are modified to perform at higher levels than their unmodified counterparts. It is hypothesized that cyborg technology will form a part of the future human evolution.
Electro-holographic display is a type of holographic display that uses electroholography for recording and reconstructing 3D objects. This display has advantages over other 3D displays; for example, it can reconstruct 3D images with full parallax.
In 2005, researchers at the University of Texas have claimed to create the first true holographic display.[4]
In 2008, scientists created the first rewritable and erasable holographic systems.[5]
In November 2010, researchers at the University of Arizona announced that they developed the fastest 3D motion hologram - which can refresh once every 2 seconds.[6]
In June 2013, the MIT researcher Michael Bove has claimed holographic televisions could be in living rooms in the next 10 years at the price of today’s two-dimensional sets because of technology being developed by Massachusetts Institute of Technology’s Media Lab.[7]
In October 2013, David Fattal was awarded Global Innovator of The Year by the MIT Tech Review for the invention of the multiview backlight technology allowing high resolution and full parallax 3D images in a wide angle of view. He became founder and CEO Of LEIA Inc which is developing an interactive holographic display for mobile devices without glasses.
Virtual Reality (VR), which can be referred to as immersive multimedia or computer-simulated life, replicates an environment that simulates physical presence in places in the real world or imagined worlds. Virtual reality can recreate sensory experiences, which include virtual taste, sight, smell, sound, and touch.
Video games :
The use of graphics, sound and input technology in video games can be incorporated into VR. Several Virtual Reality head mounted displays (HMD) were released for gaming during the early-mid 1990s. These included the Virtual Boy developed by Nintendo, the iGlasses developed by Virtual I-O, the Cybermaxx developed by Victormaxx and the VFX-1 developed by Forte Technologies. Other modern examples of narrow VR for gaming include the Wii Remote, the Kinect, and the PlayStation Move/PlayStation Eye, all of which track and send motion input of the players to the game console somewhat accurately. There is also a new high field of view VR headset system in development designed specifically for gaming called the Oculus Rift.[27] There has also been recent development in consumer-oriented omnidirectional treadmills because of Oculus Rift such as Virtuix Omni and Cyberith Virtualizer, which can simulate the motion of walking in a stationary environment. Sony announced their rival to the Oculus Rift technology as the prototype Project Morpheus at the Game Developers Conference during March 2014.
Neurohacking is the colloquial term for (usually personal or 'DIY') neuroengineering. It is a form of biohacking (qv) focusing on the brain and CNS. Strictly speaking it is any method of manipulating or interfering with the structure and/or function of neurons for improvement or repair.
Coffee, alcohol, other drugs, and over the counter medicine are all forms of neurohacking. Every one of these substances alters or "tricks" the brain into desirable conditions. When drinking coffee, the brain is fooled into thinking the body has energy and keeps the consumer awake. The brain's neurons naturally produce adenosine as a byproduct which is monitored by the nervous system. Once the level of adenosine is at a certain point, the body will feel tired. Caffeine acts as fake adenosine and binds to the body's receptors. However, instead of disappearing, it blocks the adenosine receptors so the brain's stimulants, dopamine and glutamate, can work more freely. Since neurohacking is the interference with the structure and function of neurons, coffee is in fact a neurohack. Similarly, other substances that affect the brain and functions of neurons are also neurohacks. Alcohol is the most interesting form of neurohacking because it affects multiple neurotransmitters instead of just one. This is because alcohol is a fat soluble molecule. Since lipids are a major component of cell membranes, alcohol is able to enter the membranes of neurons and change their properties. Specifically, alcohol inhibits the glutamate receptor function, enhancesGABAreceptor function, raises dopamine levels, and raises endorphin levels. This causes all sorts of reactions, including liveliness and excitement. Alcohol also causes one to lose their anxieties, because of the effect of alcohol on GABA receptors. After alcohol affects the system, it causes the body to go through what is called neurotransmitter rebound. This is because when alcohol takes effect, it overuses the GABA system so when it wears off, the GABA system makes the body feel restless.
3D printing (or additive manufacturing, AM) is any of various processes used to make a three-dimensional object.[1] In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control.[2] These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.
3D printing in the term's original sense refers to processes that sequentially deposit material onto a powder bed with inkjet printer heads. More recently the meaning of the term has expanded to encompass a wider variety of techniques such asextrusion and sintering based processes. Technical standards generally use the term additive manufacturing for this broader sense.
Before printing a 3D model from an STL file, it must first be examined for "manifold errors," this step being called the "fixup." Especially STLs that have been produced from a model obtained through 3D scanning often have many manifold errors in them that need to be fixed. Examples of manifold errors are surfaces that do not connect, or gaps in the models. Examples of software that can be used to fix these errors are netfabb and Meshmixer, or even Cura, or Slic3r.[15][16]
Once that's done, the .STL file needs to be processed by a piece of software called a "slicer" which converts the model into a series of thin layers and produces a G-code filecontaining instructions tailored to a specific type of 3D printer (FDM printers). This G-code file can then be printed with 3D printing client software (which loads the G-code, and uses it to instruct the 3D printer during the 3D printing process). It should be noted here that in practice the client software and the slicer are often combined into one software program. Several open source slicer programs exist, including Skeinforge, Slic3r, and Cura as well as closed source programs including Simplify3D and KISSlicer. Examples of 3D printing clients include Repetier-Host, ReplicatorG, and Printrun/Pronterface.
The 3D printer follows the G-code instructions to lay down successive layers of liquid, powder, paper or sheet material to build the model from a series of cross sections. Materials such as plastic, sand, metal, or even chocolate can be used through a print nozzle. These layers, which correspond to the virtual cross sections from the CAD model, are joined or automatically fused to create the final shape. Depending on what the printer is making, the process could take up to minutes or days. The primary advantage of this technique is its ability to create almost any shape or geometric feature.Note that there is one other piece of software that is often used by people using 3D printing, namely a GCode viewer. This software lets one examine the route of travel of the printer nozzle. By examining this, the user can decide to modify the GCode to print the model a different way (for example in a different position, e.g. standing versus lying down) so as to save plastic (depending on the position and nozzle travel, more or less support material may be needed). Examples of GCode viewers are Gcode Viewer for Blender and Pleasant3D.
Printer resolution describes layer thickness and X-Y resolution in dots per inch (dpi) or micrometers (µm). Typical layer thickness is around 100 µm (250 DPI), although some machines such as the Objet Connex series and 3D Systems' ProJet series can print layers as thin as 16 µm (1,600 DPI).[17] X-Y resolution is comparable to that of laser printers. The particles (3D dots) are around 50 to 100 µm (510 to 250 DPI) in diameter.
Construction of a model with contemporary methods can take anywhere from several hours to several days, depending on the method used and the size and complexity of the model. Additive systems can typically reduce this time to a few hours, although it varies widely depending on the type of machine used and the size and number of models being produced simultaneously.
Traditional techniques like injection moulding can be less expensive for manufacturing polymer products in high quantities, but additive manufacturing can be faster, more flexible and less expensive when producing relatively small quantities of parts. 3D printers give designers and concept development teams the ability to produce parts and concept models using a desktop size printer.
