EMBEDDED SYSTEM AND ROBOMAKING
[attachment=50750]
INTRODUCTION
● An embedded system is a special-purpose system in which the
computer is completely encapsulated by the device it controls.
● Examples of embedded systems
● automatic teller machines (ATMs)
● avionics, such as inertial guidance systems, flight control hardware/software and other
integrated systems in aircraft and missiles
● cellular telephones and telephone switches
● computer equipment such as routers and printers
● engine controllers and antilock brake controllers for automobiles
● home automation products, like thermostats, air conditioners, sprinklers, and security
monitoring systems
● handheld calculators
● household appliances, including microwave ovens, washing machines, television sets,
DVD players/recorders
● medical equipment
● handheld computers
● videogame consoles
TRANSISTORS
● Transistors are active components and are found every where in electronic circuits.
A junction Transistor is simply sandwiched of any type of semiconductor material
between two layer of other type. There are two type of Transistor-
● 1-PNP- when a layer of N type material is sandwiched between two layer of P type
material the
● transistor is known as PNP transistor.
● 2-NPN- when a layer of P type material is
● sandwiched between two layer of N type material
● the transistor is known as NPN transistor.
PARALLEL PORT BASIC
● COMPUTER INTERFACING:-
● It is a process of interconnecting external hardware to the computer system
i.e. external hardware is interfaced with the computer so that it can be
controlled by the computer.
● We require hardware as well as software to control external hardware
through computer system. The hardware can be connected to the computer
through various ports provided.
● A port can be considered as external opening through whish hardware can
be connected. There are two types of interfacing ports.
● 1- Serial port :- in it data is transmitted serially along a single channel i.e.
data is transmitted bit by bit along a single channel. Generally it has 9 pins.
● 2- Parallel port:-
● In computers, ports are used mainly for two reasons: Device control and
communication. We can program PC's Parallel ports for both. Parallel ports
are mainly meant for connecting the printer to the PC. But we can program
this port for many more applications beyond that.
CONCLUSION
● An engineer must have a good practical as well as theoretical knowledge.
He must be technically sound as book knowledge is incomplete.
● The technical training was an educative as well as interactive. We learned
how to make the people learn. Technical lectures presented by the
professional technicians related to topics like Robotics, Assembly language
were really interesting and healthy to learn the industrial trends. The
additional activities such as a session on Aptitude questions and
presentations related to the topics provided the chance for overall
development of an engineer. It made us learn about the importance of
teamwork.
● Research and Development center is a true platform to initiate the step
towards professionalism in an engineer’s life. I am thankful to all the
faculty members and R&D in charge for supporting my work and for
providing a right track.
