3. ABSTRACT
Now a day’s every system is automated in order to face new challenges in the
present day situation. Automated systems have less manual operations, flexibility,
reliability and accurate. Due to this demand every field prefers automated control
systems. Especially in the field of mechanics automated systems are doing good
performance.
In this system, the robot is fitted with total of five stepper motors. A
micro controller is used to control all operations. It moves the arm in all directions and
it is attached with a gripper to hold and move the objects. This vehicle is operated with
battery power. With this system we can complete our work with the robot help.
A 12V battery is provided to power the robot to perform all functions. These are
very useful for carrying files in offices, or any other material which human cannot
handle.

4. NEED OF PROJECT
 Extensive applications in hazardous conditions
 Replaced massive human work force
 Areas of application:
 Medical science
 Surgeries
 Defense
 Artificial intelligence

5. NEED OF PROJECT
 We extended applications of robotics
 To use in industries for purpose of picking and placing
objects
 To use it in case of wars
 To pull out casualties from war front
 Autonomous robot that could reach far and wide
 This gave birth to surveillance pick and place robot

6.  Defined as mechanical design capable of performing
tasks in human like manner
 Requires expertise and programming
 Sub systems
 Pick and place robot has an arm
GENERAL DESIGN

7. STEPS OF IMPLEMENTATION
 Designer needs to be fully aware of
system requirements
 Process begins with hardware design
o Mechanical design assembly
o Stable structure capable of bearing load

8. IMPLEMENTATION
 Electronic circuit is designed in ‘eagle’(Easily Applicable Graphical
Layout Editor(EAGLE))
o Microcontroller is chosen
o Circuit designed around it
 Implementation of code
o Code is compiled using ‘KEIL’ compiler
 Code tested on simulators
o Adjustments made on code
o Removal of errors

9. IMPLEMENTATION
 PCB for the main board is etched
o Components are mounted
o Soldering is done
 Testing of entire system
o Put through tasks
o Performance parameters are observed
o System checked for faults

13. FEATURES OF THE MECHANICAL
DESIN:
 Two motors for running the wheels of the robot.
 Two motors for the movement of robotic arm.
 Movement up and down
 Movement of jaw open and close
 Wireless Camera on top of the assembly
 Rectangular metal box as the base
 A Belt around wheels, in order to save on the usage of hardware.

15. APPLICATIONS:
Military applications
 Surveillance device
 To pull out casualties
 Can be used to transport objects just
on a click of a button
Industrial applications
 Loading of objects
 Serving security purposes
 Surveillance
 Reaching places out of human reach

16. ADVANTAGES:

• Programmable Serial Channel
• Low-power Idle and Power-down Modes

19. FEATURES 7805
Output Current up to 1A
 Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V
 Thermal Overload Protection
 Short Circuit Protection
 Output Transistor Safe Operating Area Protection

20. L293D LINE DRIVER
 600mA Output current capability per channel
 Over temperature protection
 Logical “0” input voltage up to 1.5 v
 Internal clamp diodes
 High voltage, high current four channel dr
 Drives inductive loads (DC motor)

21. L293D PIN CONNECTIONS
 Microcontroller
insufficient to
drive motors
 It helps to boost
supply to motors

22. DC MOTORS
 Low torque and high speed devices
 Gear set can be used to increase torque at the cost
of speed
 The movement of shaft is smooth
 Easiest to operate
 Can rotate in both directions
 Thus speed needs to be controlled to handle it
