A Robot is a programmable, multifunctional manipulator designed to move materials, parts, tools, or specialized devices through variable programmed motions for the performance of variable tasks.
    The field of robotics is in a state of rapid developments. The robots are simply programmed to perform a series of repetitive tasks. An automated device that performs functions ordinarily described to humans or operates with what appears to be almost human intelligence.
    Robots are not being generally adopted by industry, let alone for use as an assembly elements. Now a days robots are used in some applications like part inspection, welding, material handling, inventory storage. The robotics finds application in movement using object recognition, speech recognition.

    The microprocessor is a programmable device that has computing and decision making capability. The microprocessor can be embedded in a large system, can be stand alone unit controlling processes.
