What is Robot ?
A re-programmable, multifunctional, automatic
industrial machine designed to replace humans in hazardous
work. It can be used as,
An automatic machine sweeper.
An automatic car for a child play.
Used in space, military, and any more.

WHY IS ROBOTICS NEEDED…?
Robotics is needed because,
Speed
Can work in hazardous / dangerous temperature.
Can do repetitive tasks.
Can do work with accuracy.
Critical work can easily to do.

HISTORY OF ROBOT.
First use of the word
“ROBOTICS”
Three laws of
Robotics.
The first Robot
“UNIMATE”

First Use of the word “ROBOTICS”
It was the brainchild of a brilliant Czech playwright, novelist and journalist
named Karle Capek (1880-1938) who introduced it in his 1920 hit play,
R.U.R., or Rossum's Universal Robots. Robot is drawn from an old Church
Slavonic word, robota, for “servitude,” “forced labour” or “drudgery.”
Karle Capek

Three Laws of Robotics
Isaac Asimov's "Three Laws of Robotics“ and he later added a
zeroth law.
Zeroth Law.
A robot may not injure a human being or, through inaction, allow a human being to
come to harm.
First Law.
A robot must obey orders given it by human beings except where such orders would
conflict with the First Law or second Law.
Third Law.
A robot must protect its own existence as long as such protection does not conflict with
the Third Law.
Isaac Asimov

THE FIRST ROBOT “UNIMATE”
• Electronics evolved into the driving force of development with the advent of the first electronic
autonomous robots created by William Grey Walter in Bristol, England in 1948. The first digital
and programmable robot was invented by George Devol in 1954 and was named the Unimate.
William Grey Walter

Major components of robot.
Manipulator or Rover: Main body of robot (Links, Joints, Other
structural element of the robot)
End Effecter: The part that is connected to the last joint hand of a
manipulator.
Actuators: Muscles of the manipulators (servomotor, stepper motor,
pneumatic and hydraulic cylinder).
Sensors: To collect information about the internal
state of the robot or To communicate with the outside
environment.

Types of Robot.
Mobile Robots.
 Stationary Robots.
Autonomous Robots.
Remote controlled Robots.
Virtual Robots.

Mobile robot.
• Mobile robots are two types
Rolling robot
Rolling robot have wheels to move around
 they can quickly and easily search
How ever they are only useful in flat area
Walking robot
Robot on legs are usually brought in when the terrain is rocky. most
robot have at least 4 legs; usually they have 6 or more.

stationary Robots.
An autonomous robot is a robot that performs behaviours or
tasks with a high degree of autonomy, which is particularly desirable in fields
such as spaceflight, household maintenance (such as cleaning), waste water
treatment and delivering goods and services.
Autonomous Robots.
Autonomous robots are intelligent machines capable of
performing tasks in the world by themselves, without explicit human control.
Examples range from autonomous helicopters to Roomba, the robot vacuum
cleaner.

• Remote-control robots
• A remote control vehicle is defined as any vehicle that is teleoperated by a means that does
not restrict its motion with an origin external to the device. A remote control vehicle or RCV
differs from a robot in that the RCV is always controlled by a human and takes no positive
action autonomously.
• Virtual robots
• Sympa is designed to manage multiple distinct mailing list servers on a single host with a
single Sympa installation. Sympa virtual robots are like Apache virtual hosting. ... The Virtual
robot name as defined in Sympa documentation and configuration file refers to the Internet
domain of the Virtual robot.

Industrial Applications of Robot.
• Main components of industrial robot
• Arm or manipulator
• End effector
• Drive mechanism
• Controller
• Customer features:
• E.g. sensors and transducers

Robot Arms.
• A robotic arm is a type of mechanical arm, usually programmable,
with similar functions to a human arm; the arm may be the sum total
of the mechanism or may be part of a more complex robot.

Medical Application of Robot.
Robotic surgery
The performance of operative procedures with the assistance of robotic technology. It allows great prec
ision and is used for remote-control, minimally invasive procedures. Current systems consist of computer
controlled electromechanical devices that work in response to controls manipulated by the surgeon.

Used in military application
• Daksh robot
• Goalkeeper robot
• Packbot robot
• MARCbot robot

Daksh robot
Daksh is a battery-operated remote-controlled robot on wheels and
its primary role is to recover bombs. Developed by Defence Research and
Development Organisation, it is fully automated. It can navigate staircases,
negotiate steep slopes, navigate narrow corridors and tow vehicles to reach
hazardous materials. Using its robotized arm, it can lift a suspect object and
scan it using its portable X-Ray device.

Goalkeeper robot
• Goalkeeper is a Dutch close-in weapon system (CIWS) introduced in 1979
and in use as of 2017. It is an autonomous and completely automatic
weapon system for short-range defence of ships against highly
maneuverable missiles, aircraft and fast maneuvering surface vessels.
Once activated the system automatically undertakes the entire air defence
process from surveillance and detection to destruction, including selection
of the next priority target.

PackBot robot
PackBot is a series of military robots by iRobot, an international
robotics company founded in 1990. ... As of November 2014, the U.S.Army is
refurbishing 224 iRobot 510 robots. The PackBot technology is also used in
collaboration with NASA for their rovers and probes.

MARCbot robot
The Multi-function Agile Remote-Controlled Robot (MARCbot) is a
military robot created by Exponent Inc. for the United States Army Rapid
Equipping Force.
