2. Why Use Robots?
Most robots are designed to be a helping
hand. They help people with tasks that
would be difficult, dirty, dangerous, or
dull for a human
Can carry very heavy loads
Do not get bored doing the same job over
and over again, 24 hours a day.
Have been proven to increase
productivity.

3. Most of the current applications of
industrial robots are in manufacturing. The
applications can be classified into following
categories.
 Material handling
 Processing operations.
 Assembly and inspection.
ROBOT APPLICATIONS

4. MATERIAL HANDLING
Robots are used to move materials or
parts from one place to another.
Material handling applications are
divided into the following categories.
 Material transfer applications.
 Machine loading and unloading applications.

5. MATERIAL TRANSFER APPLICATIONS
The primary purpose of a robot is to
pickup parts at one location and places
them at new location. The robots used for
this purpose are called pick-and place
robots. Only two, three or four joints are
required for most of the applications.
In some cases, reorientation of the part
must be accomplished during the
relocation. A more complex example of
material transfer is palletizing, in which
the robot must retrieve parts, cartons or
other objects from one location and
deposit them onto a pallet or other
container with multiple positions.

6. ROBOT APPLICATIONS FOR MACHINE
LOADING AND UN LOADING
Industrial robot applications of machine
loading and / or unloading include the
following.
Die Casting
Plastic Moulding
Metal machining operations
Forging
Press working

7. PROCESSING OPERATIONS
Processing applications are those in which the robot
performs a processing operation on a work part. Example of
industrial robot applications in the processing category include
spot welding, continuous arc welding, spray painting and other
rotating spindle processes.
Spot Welding: It is a metal joining process in which two sheet
metal parts are fused together at localized point of contact.
Two copper based electrodes are used to squeeze the metal
parts together and then apply a large electrical current across
the contact point to cause the fusion to occur.
Robots used for spot welding are usually large, with sufficient
payload capacity to hold and use the heavy welding gun. Five
or six axes are generally required to achieve the required
positioning and orientation of the welding gun.

8. PROCESSING OPERATIONS
Spray Coating: Spray coating makes use of a
spray gun directed at the object to be coated.
Paint flows through the nozzle of the spray
gun to be dispersed and applied over the
surface of the object.
 Robot applications include spray coating of
appliances, automobile car bodies, engines
and other parts, spray staining of wood
products and spraying of porcelain coatings
on bathroom fixtures.

9. ASSEMBLY AND INSPECTION
Assembly
The assembly system is a combination of a robot, a transfer
device and part feeders.
One approach in designing assembly systems is that the
assembled object is moving on a straight line indexing or
rotary indexing table and in each station a robot is adding one
part to the assembled object.
 This configuration requires many simple robots along the
assembly line, each performing a particular operation.
The advantage of this system is the small cycle time per
product.

10. Inspection
 The robots perform loading and unloading tasks to support an
inspection or testing machine.
This case is really machine loading and unloading, where the
machine is an inspection machine. The robot picks parts that enter
the cell, loads and unloads them to carry out the inspection
process.
In some cases, the inspection may result in parts sortation that
must be accomplished by the robot.
The robot manipulates an inspection device, such as a
mechanical probe, to test the product. This case is similar to a
processing operation in which the end effector attached to the
robot wrist is the inspection probe.

11. ROBOT APPLICATIONS IN FUTURE
 The future tasks may require higher level of intelligence and decision making
capabilities, for which artificial intelligence may needs to be incorporated in
design of robot controllers.
 The future robots technology may use more advanced sensor capabilities i.e.,
vision, tactile sensing and voice communication etc.
 The future robots will have the gripper devices with the concept of universal hand
to handle tactile sensing and hand articulation.
 The future robots may perform inaccessible environments like maintenance and
repairs of complex machinery.
 The robots may be used in underground coal mining, fire fighting operations,
space etc.
 Robots can be used as security guards and may have many more domestic
applications
 The future robot technology may permit teleconference capabilities, so that
humans can command the robot from remote environment.

12. Dangerous Environments
Carrying out bomb disposal
Collecting data from volcanoes
Exploring
Military
Rescue

13. Space Robots

producing robots which can
perform maintenance in space –
especially on its International Space
Station.

15. Underwater Robots
Underwater robots are often
remote controlled vehicles with
thrusters for maneuvering and
robot arms for grabbing.
They are particularly useful in
the oil industry for welding and
valve maintenance on oilrigs.
