2. Computer vs. HumanComputer vs. Human
 Machine
 Performs precisely defined tasks with speed and accuracy
 Not gifted with common sense
 Human
 Capable of understanding and reasoning
 More likely to understand the results and determine what to
do next
 Not gifted with complex computations

3. Humanlike Computer (Robots)Humanlike Computer (Robots)
 The ideal hybrid
 Continues without human intervention when
faced with unforeseen situations
 Possesses or simulate the ability to reason
 To qualify as a robot, a machine has to be able
to do two things:
1. get information from its surroundings
2. do something physical–such as move or
manipulate objects.

4. Robotics HistoryRobotics History
The idea of a robot is not new. For thousands of years
man has been imagining intelligent mechanized
devices that perform human-like tasks. He has built
automatic toys and mechanisms and imagined robots
in drawings, books, plays and science fiction movies.

5. Robotics HistoryRobotics History
In fact, the term "robot" was first used in 1920 in a play
called "R.U.R." Or "Rossum's universal robots" by the
Czech writer Karel Capek. The plot was simple: man makes
robot then robot kills man! Many movies that followed
continued to show robots as harmful, menacing machines.
Where did the word 'robot' come from?
What is the definition of a 'robot'?
"A reprogrammable, multifunctional
manipulator designed to move material,
parts, tools, or specialized devices
through various programmed motions for
the performance of a variety of tasks"
Robot Institute of America, 1979

6. Robotics HistoryRobotics History
The term 'robotics' refers to the study and
use of robots. The term was coined and
first used by the Russian-born American
scientist and writer Isaac Asimov (born
Jan. 2, 1920, died Apr. 6, 1992). Asimov
wrote prodigiously on a wide variety of
subjects. He was best known for his many
works of science fiction.
Robotics Terminology
The most famous include I Robot (1950), The Foundation Trilogy
(1951-52), Foundation's Edge (1982), and The Gods Themselves
(1972), which won both the Hugo and Nebula awards. He also wrote
the three “Laws of Robotics for which he is also famous.

7. Law Of RoboticsLaw Of Robotics
Asimov proposed the “Laws of Robotics”
 Law 1: A robot may not injure a human being or through
inaction, allow a human being to come to harm
 Law 2: A robot must obey orders given to it by human beings,
except where such orders would conflict with a higher order law
 Law 3: A robot must protect its own existence as long as such
protection does not conflict with a higher order law
 Zeroth Law: "A robot may not harm humanity, or, by inaction, allow
humanity to come to harm"

10. Classification of RobotsClassification of Robots
 Robots are programmable computers designed to
perform a variety of tasks by moving parts, tools or
specialized devices.
 Non- adaptive robotsNon- adaptive robots - no way of sensing the environment, so
do the job regardless of any environmental factors
 Adaptive RobotsAdaptive Robots - get feedback from a sensor to alter the
operation of the device.
 Robots can also be classified according to whether they
are stationary or mobile.
 MobileMobile robots are free to move around,
 StationaryStationary robots remain in 1 place but have arms that move.

11. The Purpose of RobotsThe Purpose of Robots
Robots are also used for the following tasks:
• Dirty Tasks
• Repetitive tasks
• Dangerous tasks
• Impossible tasks
• Assist the handicapped

12. Robot ComponentsRobot Components
 Processor: The brain of the robot. It calculates the motions and
the velocity of the robot’s joints, etc.
 Sensors: To collect information about the internal state of the
robot or To communicate with the outside environment
 Software: Operating system, robotic software and the collection
of routines.
 Rover or Manipulator : Main body of robot
(Links, Joints, other structural element of the robot)
 Actuators: Muscles of the manipulators (servomotor, stepper
motor, pneumatic and hydraulic cylinder)
 End Effecter: The part that is connected to the last joint hand)
of a manipulator
 Controller: Similar to cerebellum. It controls and coordinates the
motion of the actuators.

15. Advantages VS. Disadvantages of RobotsAdvantages VS. Disadvantages of Robots
Identify which statement is an advantage and which is a disadvantageIdentify which statement is an advantage and which is a disadvantage
 Robots increase productivity, safety, efficiency, quality, and
consistency of products.
 Robots can work in hazardous environments.
 Robots need no environmental comfort.
 Robots work continuously without experiencing fatigue of problem.
 Robots have repeatable precision at all times.
 Robots can be much more accurate than human.
 Robots replace human workers creating economic problems.
 Robots can process multiple stimuli or tasks simultaneously.
 Robots lack capability to respond in emergencies.
 Robots, although superior in certain senses, have limited
capabilities in Degree of freedom, Dexterity, Sensors, Vision
system, real time response.
 Robots are costly, due to Initial cost of equipment, Installation costs,
Need for Peripherals, Need for training, Need for programming

16. Millions of Instructions per SecondMillions of Instructions per Second
(MIPS)(MIPS)
 Research scientist Hans Moravec sees a 4-
stage evolution towards universal robots,
robots with human-level intelligence flexible
enough to do a broad range of tasks. Key to
this evolution is a steady increase in
computer power, defined in terms of millions
of instructions per second, or MIPS.

task you like, a companion to do all the work
that you prefer not to, would you? And if so,
how do you think this might affect you as a
person?

20. QuestionQuestion
Are there any kind of robots that shouldn't be
created? Or that you wouldn't want to see
created? Why?
