2. ROBOT
•The term: robot has come from the Czech
word: robota, which means forced or slave
laborer.
•In 1921, Karel Capek, a Czech playwright,
used the term: robot first in his drama
named Rossum’s Universal Robots (R.U.R)
•According to Karel Capek, a robot is a
machine look-wise similar to a human
being

3. ROBOT - DEFINITION
According to Oxford English Dictionary
A machine capable of carrying out a complex series of
actions automatically, especially one programmable by a computer.
According to International Organization for Standardization (ISO):
An automatically controlled, reprogrammable,
multipurpose manipulator programmable in three or more axes,
which can be either fixed in place or mobile for use in industrial
automation applications.
According to Robot Institute of America (RIA)
It is a reprogrammable multi-functional manipulator
designed to move materials, parts, tools or specialized devices
through variable programmed motions for the performance of a
variety of tasks.

The basic components or sections in anatomy of robots
are as follows.

12. ROBOT ANATOMY
• The Anatomy of Industrial Robots deals with the
assembling of outer components of a robot such as wrist,
arm, and body.
• End Effectors: A hand of a robot is considered as end
effectors. The grippers and tools are the two significant
types of end effectors. The grippers are used to pick and
place an object, while the tools are used to carry out
operations like spray painting, spot welding, etc. on a work
piece.
• Robot Joints: The joints in an industrial robot are helpful
to perform sliding and rotating movements of a
component.

13. ROBOT ANATOMY
•The Anatomy of Industrial Robots deals with the
assembling of outer components of a robot such as wrist,
arm, and body.
• Manipulator: The manipulators in a robot are developed
by the integration of links and joints. In the body and arm,
it is applied for moving the tools in the work volume. It is
also used in the wrist to adjust the tools.
• Kinematics: It concerns with the assembling of robot
links and joints. It is also used to illustrate the robot
motions.

quickly, making them valuable to many industries.
• They are often used in research or industrial purposes
but have also been increasingly used in entertainment and
military applications.
• These robots are programmed to have human-like
behaviors.
• Humanoid robots can be used for various purposes, such
as job training, industrial and domestic use, entertainment
purposes, medical applications, or military and
governmental use.

29. FUTURE OF MANKIND AND AUTOMATION
BENEFITS :
• Robots will increase economic growth and productivity
and create new career opportunities for many people
worldwide.
• The future of automation is one in which machines
become increasingly intelligent, adaptable, and
autonomous.
• This will be driven by advances in artificial intelligence,
machine learning, and robotics, which are making it
possible to automate tasks that were once thought to be
the exclusive domain of human workers.

30. FUTURE OF MANKIND AND AUTOMATION
ETHICAL ISSUES :
• One of the biggest concerns about automation is the
potential for job displacement. As machines become
more capable of performing tasks that were once done
by humans, many jobs will become obsolete.
• This may lead to job losses in certain industries,
particularly for workers in low-skilled, routine jobs.
• However, there are still warnings out there about
massive job losses, forecasting losses of 20 million
manufacturing jobs by 2030, or how 30% of all jobs could
be automated by 2030.

31. FUTURE OF MANKIND AND AUTOMATION
ADDRESSING THE ETHICAL ISSUES :
• As automation changes the nature of work, workers will
need to be trained in new skills and technologies. This
will require investments in education and training
programs, as well as new approaches to lifelong learning
that enable workers to adapt to changing technologies
throughout their careers.
• In addition, policymakers will need to consider new
approaches to social protection and support like wage
subsidies, income support, and retraining programs to
help workers who are displaced by automation.

32. MOBILE ROBOT RESEARCH PLATFORMS
• Warthog UGV.
• Husky UGV.
• Jackal UGV.
• Ridgeback.
• Boxer.
• Dingo.
• TurtleBot 4.
• Accessories.

33. INDUSTRIAL SERIAL ARM MANIPULATOR
• Serial manipulators are the most common industrial
robots and they are designed as a series of links
connected by motor-actuated joints that extend from a
base to an end-effector.
• Often they have an anthropomorphic arm structure
described as having a "shoulder", an "elbow", and a
"wrist".
• Serial robots usually have six joints, because it requires
at least six degrees of freedom to place a manipulated
object in an arbitrary position and orientation in the
workspace of the robot.
