Robots !!!:

Robots !!! A robot is a mechanical or virtual artificial agent. In practice, it is usually an electro-mechanical system which, by its appearance or movements, conveys a sense that it has intent or agency of its own. The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as bots .

Continue…. There is no consensus on which machines qualify as robots, but there is general agreement among experts and the public that robots tend to do some or all of the following: move around, operate a mechanical arm, sense and manipulate their environment, and exhibit intelligent behavior, especially behavior which mimics humans or animals. A "Robot" is any automatically operated machine that replaces human effort, though it may not resemble human beings in appearance or perform functions in a humanlike manner. Robotics is the engineering discipline dealing with the design, construction, and operation of robots.

A walkover:

A walkover Societies in the early part of the first millennium were engaged in slavery. Man had discovered mechanics and the means of creating complex mechanisms which would perform repetitive functions such as waterwheels and pumps. Technological advances were slow but there were more complex machines, generally limited to a very small number, Man began to develop more complex machines. As mechanical techniques developed through the Industrial age we find more practical applications such as Nikola Tesla in 1898 who designed a radio-controlled torpedo and the Westinghouse Electric Corporation creation Televox in 1926.

Electronics now became the driving force of development instead of mechanics with the advent of the first electronic autonomous robots created by William Grey Walter in Bristol, England in 1948. The first digital and programmable robot was invented by George Devol in 1954 and was ultimately called the Unimate . Robots finally reach a more true assimilation of all technologies to produce robots such as ASIMO which can walk and move like a human.

Continue…. Robots have replaced slaves in the assistance of performing those repetitive and dangerous tasks which humans prefer not to do or unable to do due to size limitations or even those such as in outer space or at the bottom of the sea where humans could not survive the extreme environments. We still use robots in a wide variety of tasks such as vacuuming floors, mowing lawns, cleaning drains, investigating other planets, building cars, entertainment and in warfare. Modern robots are usually used in tightly controlled environments such as on assembly lines because they have difficulty responding to unexpected interference. Because of this most humans rarely encounter robots. However domestic robots for cleaning and maintenance are increasingly common in and around homes in developed countries.

Types of Robots:

Types of Robots Robots come in those two basic forms: Those which are used to make or move things, such as Industrial robots or mobile or servicing robots. Those which are used for research into human-like robots such as ASIMO and TOPIO as well as those into more defined and specific roles such as Nano robots and Swarm robots.

Categories of Robots:

Categories of Robots Movable robot Service robot (a pick and Place robot in a factory) Industrial robots (or Manipulating Robots) Military robots Contemporary uses

Movable/Mobile robot:

Movable/Mobile robot Movable robots have the capability to move around in their environment and are not fixed to one physical location. An example of a mobile robot that is in common use today is the automated guided vehicle or automatic guided vehicle (AGV). An AGV is a mobile robot that follows markers or wires in the floor, or uses vision or lasers. Mobile robots are also found in industry, military and security environments. They also appear as consumer products, for entertainment or to perform certain tasks like vacuum cleaning.

Industrial robot:

Industrial robot Industrial robots usually consist of a jointed arm (multi-linked manipulator) and end effectors that is attached to a fixed surface. One of the most common type of end effector is a gripper assembly. The International Organization for standardization gives a definition of a manipulating industrial robot in ISO 8373: “An automatically controlled, reprogrammable, multipurpose, manipulator programmable in three or more axes, which may be either fixed in place or mobile for use in industrial automation applications .“

Service robots:

Service robots Most commonly industrial robots are fixed robotic arms and manipulators used primarily for production and distribution of goods. The term "service robot" is less well-defined . IFR has proposed a tentative definition, "A service robot is a robot which operates semi- or fully- autonomously to perform services useful to the well-being of humans and equipment, excluding manufacturing operations."

Military robots:

Military robots Use of robots for military purpose has always been questionable. One robot in particular, the EATR, has generated concerns over its fuel source as it can continually refuel itself using organic substances. Although the engine for the EATR is designed to run on biomass and vegetation specifically selected by its sensors which can find on battlefields or other local environments the project has stated that chicken fat can also be used .

Continue…. The BAE Taranis is a UCAV built by Great Britain which can fly across continents without a pilot and has new means to avoid detection. Military robots include the SWORDS robot which is currently used in ground-based combat. It can use a variety of weapons and there is some discussion of giving it some degree of autonomy in battleground situations. Unmanned combat air vehicles (UCAVs), which are an upgraded form of UAVs, can do a wide variety of missions, including combat.

Contemporary uses:

Contemporary uses At present there are 2 main types of robots, based on their use: General-purpose autonomous robots Dedicated robots. Robots can be classified by their specificity of purpose.

General Purpose Autonomous Robots:

General Purpose Autonomous Robots Those which can perform a variety of functions independently. They typically can navigate independently in known spaces, handle their own re-charging needs, interface with electronic doors and elevators and perform other basic tasks. Like computers, general-purpose robots can link with networks, software and accessories that increase their usefulness.

General-purpose robots may perform a variety of functions simultaneously or they may take on different roles at different times of day. Some such robots try to mimic human beings and may even resemble people in appearance; this type of robot is called a humanoid robot or Androids.

Dedicated Purpose Autonomous Robots:

Dedicated Purpose Autonomous R obots Factory robots Car production Packaging Electronics Automated guided vehicles (AGVs ) Early AGV-Style Robots : Interim AGV-Technologies Intelligent AGVs ( i -AGVs )
