3. Introduction:-In 1950, the NC machine changed the whole concept
and pace of manufacturing which was markedly revolutionlished
with the introduction and application of computers in
manufacturing. This improvements have continued and the entire
concept and scope manufacturing has drastically changed with the
advancement in micro-processor electronic computer technology,
control system and many of other similar areas.
A very useful development in this series of innovations are the
robots, especially Industrial Robots.
4. WHAT IS ROBOT:
“A robot is a programmable multifunctional manipulate designed to move material, parts,
tools or special devices through variable programmed motions for the performance of a
variety of tasks”.
5. OBJECTIVES OF USING ROBOTS:
•To increase productivity.
•To rise the quality level of products.
•To minimise the labour requirement.

13. ROBOT SENSING AND SENSORS:
In the pursuit of imparting more and more artificial intelligence to a robot, in
order to bring its operations nearer to that of a human being, efforts continue to
be made for improving its sensing abilities, i.e. its vision, hearing, feeling by
touching other objects.
ROBOT PROGRAMMING AND LANGAUGE:
