3. Robot exactly, is a system that contains sensors, control systems, manipulators,
power supplies and software all working together to perform a task. Designing,
building, programming and testing a robot is a combination of physics,
mechanical engineering, electrical engineering, structural engineering,
mathematics and computing.
The pick and place robot is a microcontroller based mechatronic system that
detects the object, picks that object from source location and places at desired
location.
The project is designed to develop a pick n place robotic vehicle with a soft
catching gripper. The project is aimed to design and develop a pick and place
robotic vehicle with a catching gripper. The project will include development of
an android app and mobile robot which will be able to move objects from one
place to another. Thus, controlling the vehicle remotely. Remote operation is
achieved by any smart-phone/Tablet etc., with Android OS; upon a GUI
(Graphical User Interface) based touch screen operation. This prototype will
pave path for real life models using the same concept.
5. INTRODUCTION
• A robot is an automatic mechanical device guided by a computer
program or electronic circuit
• In highly developing society automation playing important role to save
human efforts in most of the regular &frequently carried works
Ex. Most of the industrial jobs like welding, painting, assembly,
container filling etc. Most commonly performed work is picking and
placing of jobs from source to destination.
For this purpose, ‘Mobile Pick And Place Robot commonly
named as Remote Controlled Robotic Vehicle(RCRV),maybe
used.

8. Mobile Pick And Place Robot
Pick And Place Robot is a mechatronic system that picks
object from source location and places at desired location.
For detection of object, infrared sensors are used which detect
presence of object as the transmitter to receiver path for
infrared sensor is interrupted by placed object. As soon as robot
senses presence of object, it moves towards object, picks it with
end effectors, and moves along way gantry and finally place it
on destination.
If another object causes interrupt, it again does the same job.
Whole process is controlled by micro controller.
9. • Mobile Pick and Place Robots speeds up the process of picking parts up
and placing them in new locations, while also increasing production rates.
• These mobile pick and place robots are more accurate and do not fatigue
while doing back-breaking movements that may be difficult for humans.
• The consistency, quality and repeatability of a mobile pick and place robot
system is unmatched. These systems are also versatile and can be
reprogrammed and tooled to provide multiple applications for consumers.
• An increase in output with a mobile pick and place robot system offer
long-term savings to companies. With the advancements in technology
and affordability of robots, more pick and place robotic cells are being
installed for automation applications.

11. Robotics Terminology
Link: A rigid piece of material connecting joints in
robot.
Joint: The device which allow relative motion
between two adjoining link of robot.
ROBOTICS MOVEMENT
• Rotational movement
• Radial movement
• Vertical movement
13. Jointed Arm robot
DOF- Degree of Freedom can be Define as no . Of independent
motion a device can perform.
14. 1. DC MOTORS: This is very commonly used in robotics. DC motors
can rotate in both direction depending upon the polarity of the
current through the motor . These motors have free running torque &
ideally zero current. These motors have high speed which can be
reduced with the help of gears.
2. GRIPPER ARM: The gripper
module is state of the art robotic arm
which can be used in various 'pick and
place' kind of robots. It works on DC
Motor (9 to 12V DC).
•Change in rotation direction of the DC
Motor, generates Jaw Open & Close
Action.
•The DC motor can be easily be controlled
with
the help of DPDT Switch (manual mode)
or
15. 3. LIFTER ASSEMBLY: It is made from laser cut Metal and acrylic. There is a
DC motor (9 to 10 volt) to
worm gear and spur gear assembly which is attached with a provide torque so
that gripper can pick and lift the load.
4.TRACK WHEEL: Track wheel is a circular wheel with rubber grip fastened
on DC motor shaft by screw. Track wheel provide help in movement of robot in any
direction.
5.Worm drive: Worm drive is a gear arrangement in which a worm (which is
a gear in the form of a screw) meshes with a worm gear (which is similar in
appearance to a spur gear, and is also called a worm wheel).
(a)Spur gear (b) Worm gear,
(Made by acrylic fiber)
16. 6. CHASSIS: A chassis consists of an
internal framework that supports a man-
made object in its construction and use. It
is analogous to an animal's skeleton. An
example of a chassis is the under part of
a motor vehicle, consisting of the frame
(on which the body is mounted). Here
metallic chassis is used.
7. POWER SUPPLY:
To provide energy to DC motors for
movement of robot A Battery of DC (6
volt to 12 V, 4.5A) is being used.

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.
Savings - Managers are realizing the longterm savings with a pick and place robotic work cell rather than
the operation they are currently doing. An increase in output with a material handling robotic system has
saved factories money.
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.
