2. Introduction to Robotics
Up growing technology finds Automation is the
important tool which shows more impact on the areas
which are not reachable and manageable by the
human being with the help of Interactive Machines
whose body languages are the replicas of human
being. The technical name given to the Interactive
Machine is the Robot which works under the control
of his Master. This is the modernized way in the
present days.
3. Speed : Pick and place robots allow for faster cycle times.
Accuracy: Robotic systems are more accurate and consistent
than their human counterparts.
Production : Work cells create more because they perform
applications with more accuracy, speed and tirelessness. The
consistent output of a robotic system along with quality and
repeatability are unmatched
Reliability: Robots can work 24 hours a day, seven days a week
without stopping or tiring.
Flexibility : Pick and place robots can be reprogrammable and
tooling can be interchanged to provide for multiple
applications.
Affordability : With the advancements in technology, and
affordable robotics becoming available at less cost, more pick
and place robotic cells are being installed for automation
applications.

6. Introduction to power supply unit
There are many types of power supply. Most are
designed to convert high voltage AC mains electricity
to a suitable low voltage supply for electronics circuits
and other devices.
A power supply can by broken down into a series of
blocks, each of which performs a particular function.
Regulator eliminates ripple by setting DC output to a
fixed voltage.
Voltage regulator ICs are available with fixed (typically
5V, 12V and 15V) or variable output voltages.

14. Metal Detection
A metal detector is a device which responds to metal that may not be
readily apparent.
The simplest form of a metal detector consists of
an oscillator producing an alternating current that passes through a
coil producing an alternating magnetic field. If a piece of electrically
conductive metal is close to the coil, eddy current will be induced in
the metal, and this produces an alternating magnetic field of its own. If
another coil is used to measure the magnetic field (acting as
a magnetometer), the change in the magnetic field due to the metallic
object can be detected.
They are extensively used for mining and other industrial
applications. Uses include demining (the detection of land mines), the
detection of weapons such as knives and guns, especially in airport
security , geophysical prospecting, archaeology and treasure hunting.
Metal detectors are also used to detect foreign bodies in food, and in
the construction industry to detect steel reinforcing bars in concrete
and pipes and wires buried in walls and floors
16. L293D - MOTOR DRIVER IC
•The L293D IC is a 8
pin IC used for
driving motors
•It is having
capability of driving
two motors at a time
•Motor driver circuit
is used in the place
of relay circuit , so
that complication of
circuit is reduced.
18. RS232-SERIAL COMMUNICATION
•The RS232 cables are generally referred to as DB-9 connector. In labeling,
DB-9P refers to the plug connector (male) and DB-9S is for the socket
connector (female).
•The simplest connection between a PC and microcontroller requires a
minimum of three pin, TXD, RXD, and ground. Many of the pins of the
RS232 connector are used for handshaking signals. They are
• The AT89C52 has two pins that are used specifically for transferring and
receiving data serially. These two pins are called TXD and RXD and are part
of the port3 (P3.0 and P3.1).
• These pins are TTL compatible; therefore they require a line driver to make
them RS232 compatible.
•One advantage of MAX232 chip is that it uses a +5v power source which is
the same as the source voltage for the at89c51. The MAX232 has two sets of
line drivers for receiving and transferring data.
•The line drivers for TXD are called T1 and T2 while the line drivers for RXD
are designated as R1 and R2. T1 and R1 are used for TXD and RXD of the
89c51 and the second set is left unused.
21. Introduction to X-bee Module
X-Bee enables broad-based deployment of wireless
networks with low-cost, low-power solutions. It provides
the ability to run for years on inexpensive batteries for a
host of monitoring applications: Lighting controls, AMR
(Automatic Meter Reading), smoke and CO detectors,
wireless telemetry, HVAC control, heating control, home
security, Environmental controls and shade controls, etc.
In all of its uses, X-Bee offers four inherent, beneficial
characteristics:
Low cost
Range and obstruction issues avoidance ,Multi-source
products, Low power consumption.
24. Applications
Pick and Placing the Objects: Most commonly
used in industries such as bottling plants and
automobile manufacturing units.
Detecting the Land Mines: Generally used as a
substitute to replace human effort to detect the land
mines which are consign with security.
Image and Video Transmitting: This is the
modernized specification here the video or the images
captured are transmitted to the receiving end and
hence the image for the object that is being picked or
the mine that is detected can be easily identified .
25. Conclusion
The pick and place robot has its way in many of the
industrial applications and manufacturing industries
where it is used to pick & place different objects .
The metal detector has its importance and mainly
used for the security in airports and in places to detect
the underground land mines , and to detect the
presence of any metals or harmful objects.
The image processing phenomenon provides a finite
distinction and helps to locate the place where the
metal or mine is located and transmits the picture
and video of the object that is being picked.
