This document describes a project to design a remotely controlled robotic vehicle with an arm. The objectives are to allow remote control via Bluetooth and synchronous movement of the vehicle and arm. The proposed method is to combine the vehicle and arm for semi-automated operation. Key components include an Arduino board, motor drivers, Bluetooth module, and chassis. The arm and vehicle can be controlled through a mobile app. Applications include pick and place, material handling, and industrial tasks like welding. Advantages over manual labor include speed, accuracy, reliability and affordability.

3. INTRODUCTION
A robot is an automatic mechanical device guided by a
computer program or electronic circuit.
In highly developing society automation playing an
important role to save human efforts in the most of
regular carried works.
Ex. Most of industrial jobs like welding, assembly,
container filling etc. Most commonly performed work is
picking and placing of jobs from source to destination.
For this pick and place robot is used.

4. OBJECTIVE
The primary object of the system is to design in such
a way that user can operate the robot through remote
controlling via Bluetooth. This involves the
movement of both robotic arm and vehicle in
synchronous with user's guidelines.
By interfacing the robotic vehicle with robotic arm ,
moment of the arm will be easy such that the work
can be done at multiple places.
 This system achieves a semi-automatic robotic arm.

5. EXISTING METHODS
Till now humanoid arms are designed and built to
mimic human form and movement.
They are meant to resemble the size and physical
abilities of a human in order to function in human-
oriented environments.
The Robotic vehicle adopts an algorithm to avoid
obstacles and the dexterous hand is capable of
grasping objects.
These kind of arms are not capable of performing
industrial works because of their kind of design.

6. PROPOSED METHOD
Combining the vehicle with the robotic arm is the
main method for achieving the semi-automation.
By using the vehicles more accurate results can be
obtained and do not fatigue while doing back-
breaking movements that may be difficult for
humans.

7. This is a mechatronic system which can be used for
picking the object from source location and places at
desired location.
These systems are versatile and can be reprogrammed
and tooled to provide multiple applications and can
easily perform industrial works.

9. BLOCK DIAGRAM EXPLANATION
The AURDUINO UNO is the main controller of the
robotic vehicle.
The battery and diode is connected to the aurduino ,
which gives input to the aurduino.
The two motors were connected to the motor driver.
The both motor drivers are used, one is for arm
operation and another for vehicle operation.

10. ROBOTIC 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

11. MAIN COMPONENTS
Arms or Manipulator
Motor driver
Aurduino board
Bluetooth module
Gesture control
Chassis

12. OPERATION OF ARM
Pick and Place Robot is a mechatronic system that picks
from source location and places at desired location.
By using ultrasonic sensor while an obstacle is being
sensed then automatically car stops for smooth transport
of the material.
With end effectors the object is picked up and moves to
the desired location.
Mobile Pick and Place Robots speeds up the process of
picking and placing them in new locations, while also
increasing production rates.

13. OPERATION OF VEHICLE
The controlling of the vehicle is done by gesture
control or using app.
 These vehicles are more accurate and do not fatigue
while doing back-breaking movements that may be
difficult for humans.
The consistency, quality and reliability of pick and
place vehicle system is unmatched. These systems are
also versatile and can be reprogrammed and tooled to
provide multiple applications.

14. The vehicle will move rotational radial and vertical
motions.
By using an app we can control the vehicle and arm of
the robot .
The arm will turns around 180 degrees.
The vehicle will turns around 360 degrees.

15. MOTOR DRIVER PIN DIAGRAM

16. MOTOR DRIVER APPLICATION
 L293D contains two inbuilt H-bridge driver circuits. In its
common mode of operation, two DC motors can be driven
simultaneously, both in forward and reverse direction.
 The motor operations of two motors can be controlled by input
logic at pins 2 & 7 and 10 & 15.
 Input logic 00 or 11 will stop the corresponding motor.
 Logic 01 and 10 will rotate it in clockwise and anticlockwise
directions, respectively.
 Enable pins 1 and 9 (corresponding to the two motors)
must be high for motors to start operating.

17. PIN DESCRIPTION OF ARDUINO UNO

18. AURUDUINO ARCHITECHTURE
 Basically, the processor of the Aurduino board uses
the Harvard architecture where the program code and
program data have separate memory.
It consists of two memories such as program memory
and data memory.
Wherein the data is stored in data memory and the
code is stored in the flash program memory.
The Atmega328 microcontroller has 32kb of flash
memory, 2kb of SRAM 1kb of EPROM and operates
with a 16MHz clock speed.

19. BLUETOOTH MODULE
The Bluetooth module HC-05 is a MASTER/SLAVE
module. By default the factory setting is SLAVE.
The Role of the module (Master or Slave) can be
configured only by AT COMMANDS.
The slave modules cannot initiate a connection to
another Bluetooth device, but can accept connections.
 Master module can initiate a connection to other
devices.
The user can use it simply for a serial port replacement
to establish connection between MCU and GPS, PC to
your embedded project, etc.

20. GESTURE CONTROLS
Gestures are an important aspect of human
interaction, both interpersonally and in the context of
man-machine interfaces by using the Bluetooth
module.
A gesture is a non-verbal communication in which
visible bodily actions communicate particular
messages, either in place of speech or together and in
parallel with words.
Gestures include movement of the hands, face or other
parts of the body.
