The Undeniable Robots

                        ROBOTS OUR NEED 

The world of robots, like computer, is witnessing an unprecedented changes.

Micro-miniaturization and phenomenal increase in speed and flexibility are rapidly turning robots into becoming an inseparable part of our daily life.These unpaid mechanical servants of men is known for there precision and accuracy are rapidly becoming excellent supplements for humans.

   what is actually ROBOT and its origin

The word "ROBOT" (which is given by Oxford English Dictionary) is"An intelligent artificial 

being typically made of metal and take after in some way human or other animal".

The word "ROBOT" came  to English via Germany although the word has been acquired from"Czech Robota" which means   ' forced exertion' or 'slavery'

•    In Modern era 

Though robots first appeared in US, today japan leads in the fields of robots. Japan has been able  to produce cars and watches quite inexpensively by making use of robots, which can weld faster and better than human beings.It has been estimated that one robot can do the job of two to five workers. robots are ideally used for mixing lethal chemicals, fight fires and handle hazardous wastes. The can also perform the job of 

cleaning the reactor and replacing nuclear fuel.

• Future Ongoing Development on Robots 

Parallel to the ongoing trends on computers , smaller and smarter robots are under development. Like computers they are shrinking in size but growing in might.

Currently Bell Labs, Massachusetts Institute Of Technology (MIT), University of

California , and many labs in Japan aimed of developing robots no bigger then 

the size of a grain. The rapidly diminishing size of silicon has come handy for

for evolving mini robots. Sound insight into the intricacies of micro machining of motors, transmissions and joints are crucial to the development of "microbots".

Miniature electrostatic motors and cylinder-shaped lenses form important components of microbots. However, the application potential of microbots is limited. Microbotics technology can lead to compact space craft hardware, new microsurgical tools and microscopic drug delivery pellets. The grain-sized robots can be programmed to search

deep into the entrails of an aircraft or launch vehicles to carry out fine repair work.

• Further Visions And Generations.

On another front, serious attempts are on to develop robots endowed with emotional 

and free-will capabilities. For this use of neutral networking, artificial intelligence and

fuzzy logic are being scrutinize.

Many classifications of robots based on physical structure and functional potentials

have been made. Industrial robots devised and used until 1980 were categorized as 

first generation machines. Essentially, they were used for processing spot welding,

spray painting and assembly. Most of them were nothing but "pick" and "place"

devices repeating a set of jobs routinely.

The second generation robots that are now being used  for  a wider range of purposes

has complete synchronization of hand, eye coordination, with sensory control and 

flexible programmability. They find use in welding, assembly and integration and 

inspection of nuclear reactors.

The futuristic third generation robots-now in a experimental stage-will have the intelligence

to see, feel, walk, hear, respond, interpret and correct. Specially they will be deployed 

for spraying insecticides, tree felling, marine development, ocean exploration, fire fighting 

and helping the handicapped.

The third generation robots are also required to be dynamically mobile. In this context,

researcher should devise on-off line programming for simulating the behavior of the 

robot in an environment.
