Robotics

A robot is a mechanical intelligent agent which can perform task on its own, or with guidance. In practice the robot is usually an electromechanical machine which is guided by computer and electronic programming. At first the machines was initially used for simple household tasks such as water lifting, grinding etc. But with the development of advanced technology robots are become more complex and can solve many hard problems.
In development of robot we find Niko Tesla designing a radio controlled torpedo. Gakutensoku, which cried and changed its facial expressions. The first electronics robot created by William Grey Walter in Bristol, England, in 1948 made an evolution on robots history. The ultimate, 1954 was the digital and programmable robot. On development, ASIMO could walk and move likes a human. It has overcome the size limitation of human or even those such as in outer space or at bottom of sea where human couldn't survive. Now robots are used in very large varieties such as cleaning floors, drains mowing lawns, investigating other planets, building cars, in entertainment and in war force. Now the Japanese "karakuri giemun" has created an array of extremely complex mechanical toys.
So the robot is any automatically operated machine that replaces human effort though it may not resemble human beings in appearance or performs functions in a human like manner. They should be used in industrial jobs that will give more product and we can use it for entertainment purpose also.
