Force through intelligence
A machine or a device
operates automatically or by
remote control.
Robot is a machine that
collects the information
about the environment using
some sensors and makes a
decision automatically.

History
Word robot was coined by a
Czech novelist Karel Capek in
a 1920 play titled Rossum’s
Universal Robots (RUR)
Robota in Czech is a word for
worker or servant

Robotics
 It’s a branch which deals with design, fabrication
& application of robots.
Mech.Engg – Mechanism & structure
Elect.Engg – Sensing & controlling
Computer Engg – Planning of Motion

Classification of robots
Simple level Robots
 Automatic machine cannot be programmed and does
not contain a complex circuitry.
Middle level Robots
 Robots which can be programmed but cannot be
reprogrammed. They have sensor based circuit
Complex level Robots
 Robots which can be programmed and also
reprogrammed. They are multifunctional manipulators

6. Examples
Wheeled Robot
Legged Robot
Autonomous Underwater Vehicle

Details
mechanical linkage-which consists set of rigid
LINKS ,JOINTS and END EFFECTORS
 END EFFECTORS The last link or the most distal
link is called the end effectors it is this link to which
a gripper or a tool is attached

9. Cont.
Transmissions- GEARS,CHAINS, LINKAGES are
used
The actuator output is not directly suitable for driving the
robot linkage.
Actuators are usually big and heavy and often it is not
practical to locate the actuator at the joint

Cont…
Sensors - Control of a industrial robot is based on
the correct interpretation of sensory information
Tactile sensors-It deals with collision detection
Proximity sensors-Thus how much a Robot is
away from an object
Machine vision-inspection,parts
identification,guidence
Miscellaneous-Used in robots that need to
maintain balance.

ADVANTAGES OF ROBOTS
increase productivity, safety, efficiency, quality, and
consistency of products
work continuously without any humanity needs and
illnesses
Robots have repeatable precision at all times
Robots can process multiple stimuli or tasks
simultaneously

12. 12
DISADVANTAGES OF ROBOTS
Robots lack capability to respond in emergencies
A lack of decision-making power
• Robots may have limited capabilities in
 – Degrees of Freedom, Sensors ,Vision systems
Robots are costly, due to
 – Initial cost of equipment
 – Installation Costs
 Need for Programming

APPLICATIONS OF ROBOTS
These are the main fields
Automotive industry
Assembly
Medical laboratories
 
Medicine
Nuclear energy
Agriculture
Underwater inspection
Customer service
 
Arts and entertainment

14. Automotive industry is one of the most important partners in
the development of robotic technologies. In automotive
industry the Robots are used for:
Manipulate very heavy loads
Robustness and precision of the assembly of pieces
Found in painting rooms for spray painting
Industry
Used for places that is hard to reach.
Welding of various parts
Automotive Industry:

15. Assembly:
Another strong partners is the assembly of manufactured
products
Execute repetitive sequence of movement, boring, demotivating and
dangerous tasks at constant performance.
Many tools are attached at the extremity of a manipulator
Use the optimal sequence of operations
Can monitor the quality assembly line with
adapted enhance sensor technologies

16. Underwater inspection:
Robots are used for under water inspection where human
bodies cannot survive
Submersible robots have been used for many years to explore sea beds.
Rescuing ship-wrecked persons
Retrieving black boxes of crashed planes.
Exploring deep sea and old wrecks in order
to find their secrets.
Inspection of the flooded side of dams to
detect the cracks
Inspect and maintain oil digging platforms
