2. Robots
• Robotics is the branch of technology that
deals with the design, construction, operation
and application of robots.
• Robot is a reprogrammable multifunctional
manipulator designed to move materials
parts, tools, or special devices through
variable programmed motions for the
performance of variety of tasks.
3. ROBOT ANOTOMY
• The manipulator or an industrial robot is
constructed by a series of joints and links.
• Robot anotomy deals with the types and the
size of joints and links and other aspects of
the manipulator’s physical construction.
4. CLASSIFICATION OF ROBOTS
• Depending upon the physical
configuration
– Cartesian robot: In this robot consist of
three sliding joints. Out of which one is
linear and other two are orthogonal.
– Cylindrical robot: In this robot consist
of a vertical column relative to which an
arm assembly moves up and down.
5. – Polar robot: In this sliding arm of
body can rotate about both
vertical and horizontal axis
– Jointed arm robot: It has a
structure swiveled about the base
with shoulder joint and elbow joint
etc.
6. • Depending upon the motion characteristics
– Point to point robot
– Continuous path robot
• Depending upon the types of control used
– Servo control robots
– Non-Servo control robots
8. APPLICATION OF ROBOT
• Industrial application
– Used for material handling.
– Processing operations like
• Welding
• Spray painting
• Casting
• Heat treatment
• Finishing operation
– Assembly
– Inspection
9. • Non-Industrial application
– Space application
– Agricultural application
– Ocean exploration.
– Defense
– House-hold jobs etc.

14. Advantages of Robots
• Robotics and automations can increase safety,
reliability, production amount, profit, quality and
quantity of products in a lot of cases.
• They can do jobs in dangerous situations and save
lives of thousands of people.
• They do not care about the comfort of their
environment. Human needs such as hunger or
depression have no meanings for them. They do
not get tired.
• Their accuracy is so high and is in the range of
millimeters or even micrometers.
15. Disadvantages
• Robots can not respond properly at the times
of emergency and danger.
• They are expensive.
• They Have limited duties. They can only do
what they have been ordered to do.
