2. Hi every one, this is B.M.S.Pranava Raman. Today we are
gonna see about Robotics. Click the slide you want to go. After
that click the click here button that is present in every slide.

3. Robotics is the branch of technology that helps us in the
designing, constructing, operating and application of robots and
computers. This makes the robots deal with dangerous persuasions
that cant be deal by humans. Many of todays robots are bio
inspired. Continued in next slide.. 12-06-2015 15:20B.M.S.PRANAVA

5. There are many robotic languages such as VAL, VAL 3, Epson
RC+, Robo forth, etc. Now we are going to see an example of a
industrial robot language called VAL. Click here 12-06-2015
15:20B.M.S.PRANAVA RAMAN 5
6. Think yourself as a robot which has a industrial robot
language called VAL. You want to go to the P3 and take the circle
and place it at P5 and you are in P0, then what would be the
command? Now you will see the answer. Click here 12-06-2015

7. VAL was one of the first industrial robotic languages, it
was used in Unimate. This is just an example. Click here 12-06-2015
15:20 B.M.S.PRANAVA RAMAN 7 The commands are Move to P1 (a general
safe position) Move to P2 (an approach to P3) Move to P3 (a
position to pick the object) Close gripper Move to P4 (an approach
to P5) Move to P5 (a position to place the object) Open gripper
Move to P1 and finish Home P1 P2 P3 P4 P5
8. The word robotics is derived from the word robot. The word
robot was discovered by a Czech writer Karel apek in his play R.U.R
[Rossums Universal Robots] which was published in 1920. The word
robot was derived from the Slavic word Robota which means labor.
The word Robotics, according to the Oxford English Dictionary, was
first used in a print of Issac Asimov in his short science fiction
story Liar which was published in 1941. Click Here 12-06-2015

9. Only in 1927 did the first humanoid robot appeared in a
film. It was Issac Asimov who made the three laws for Robotics.
Fully autonomous robots only appeared in the 20th century. The
first industrial robot was Unimate. It was installed in 1961. The
First description about automata was written in 3 century BC and
earlier. The design for humanoid automata was made by Leonardo Da
Vinci in 1495. The Humanoid Robot was made in 1930 by Washington
Electric corporation. An universal manipulation arm was discovered
in 1975 by Victor Scheinman. Click Here 12-06-2015

10. There are many components in a robots body. Let us see
about them. Power Source Actuation Sensing Manipulation Locomotion

11. There are 4 types of potential power source. They are:-
Pneumatic (compressed gas) Hydraulic (liquid) Flywheel energy
storage Organic garbage Humans and animal faeces At present mostly
lead-acid batteries are used as power source. They are very heavy
and cheap. There is another type of battery named as silver cadmium
batteries.They are of light weight but costly. We can use any type
of power source for our robot from the upper list. Click here

12. Actuators are like muscles of the robot. There are many
types of actuators. They are:- Electric motors Linear actuators
Series elastic actuators Muscle wire Air muscles Piezo motors
Electroactive polymers Elastic Nanotubes Click here12-06-2015

13. Sensors allow the robots to receive information about
measurements. This is essential for robots to perform their tasks.
This helps to give the warning to the robots about safety or
malfunctions. Well see about these robotic sensing in the upcoming
slides. There are two types of Sensing. They are :- Touch Vision

14. Robotic and prosthetic hands receive less tactile than the
human hands, but now they have discovered mechanical properties
that mimic the human touch mechanism in the robot. The sensor has a
special type of skin which help it to sense. European scientists,
have discovered a prosthetic hand in 2009, called Smart Hand. It
helps the patients to write, type and do everything as a normal
man. Click here 12-06-2015 15:20B.M.S.PRANAVA RAMAN 14
15. Computer vision is a technology that helps the machines to
see and sense. As a scientific discipline, it capture photos or
videos and sequences it to understand. The robots are
pre-programmed for computer vision. Computer vision detect the
electromagnetic radiation in the form of visible light or infra-red
light. The sensors are designed using solid state physics. It
reflects using optics. Robots can also be equipped with multiple
vision sensors. Like human eyes, robot eyes must also be able to
focus on a particular area of interest. Click here 12-06-2015

16. Robots need to manipulate objects; pick up, modify,
destroy, or otherwise have an effect. Thus the "hands" of a robot
are often referred to as end effectors while the "arm" is referred
to as a manipulator. Most robot arms have replaceable effectors,
each allowing them to perform some small range of tasks. Some have
a fixed manipulator which cannot be replaced, while a few have one
very general purpose manipulator, for example a humanoid hand.
There are many types of manipulators, They are:- Mechanical
Grippers Vacuum Grippers General Purpose Effectors Click Here

18. The way of interacting with a robot is called as Human
robot interaction. There are 6 ways to interact. They are:- Speech
Recognition Robotic Voice Gestures Facial expression Artificial
emotions Personality Click here 12-06-2015 18
19. There are many types of control Well see from the basics to
autonomous levels. 12-06-2015 19
