ABSTRACT
In the present era the usage of mobile phone is very wide, cell phone is not merely a device to
communicate with other persons but it is also very much useful to communicate and command
the machines also. This project is one of them
The project mainly cites that even through a cell phone we can control and operate the robot by
through short messaging service i.e. (SMS) technique, which is the special feature of the project.
And above all it is fully operated with the help of battery.
The appearance and capabilities of the robot vary vastly. The robot shares the feature of
mechanical and movable structure under some form of structures. The robot has mainly three
phases: perceptions, processing and action. Perception includes receiving commands from the
cell phone, processing includes work done by microcontroller, and finally momentary actions
done by motors.
This project is designed with robot assembly, where SMS is sent to the GSM module attached to
the robot and after receiving it the micro controller processes it with the help of level converter,
data cable, relay circuit, relay. In micro controller we have programmed to get the input signal
from the GSM module through the data cable and the micro controller will activate the relay
through the relay driver circuit contains transistors, which acts as the switch. So it can control
the relay. The relays outputs are connected to dc motors and the dc motors will drive the robot
according to the command received. Level converter is nothing but RS232 the output of the cell
phone signals given to level converter in which the signal are converted into 0 and 5v pulse then
these signals given to micro controller.
For an example, if we want to drive the robot to forward direction we have to send SMS to
the GSM module which is connected to robot. After receiving the SMS the module sends the
corresponding signal to micro controller through the data cable and level converter, now the
micro controller activate the corresponding relay, so DC motor will be operated robot moving in
the forward direction. Similarly we can drive the robot to reverse direction left side and right
side as well.

Introduction
1.1 The broad statement of design problem
Cell Phone Oriented Robotic Vehicle “Connecting people with gadgets-The functionality
in physical absence.”
We all are almost using mobile phones which are basically used to communicate with
humans but here we are using it to interact with a robot. Here we have designed a robot in
such a way that it will be able to sense the SMS- Short Messaging Service sent from any
mobile and act accordingly. The robot must be designed such that it can be administered
wirelessly by any Android device via SMS. The GSM module present in the robot should be
able to attain the commands from the Android device and process them appropriately in order
to operate the robot by varying the speed and direction of the motors.
The project mainly cites that even through a cell phone we can operate any machine by only
giving SMS. The appearance and capabilities of the robot vary vastly. The robot shares the
feature of mechanical and movable structure under some form of controls. The robot has
mainly 3 phases
 Perception- involves receiving of commands from cell phone.
 Processing-done by microcontroller
 Action-Task is done by motors i.e. movement.
Normally the wireless controlled robots have a drawback of limited frequency range and
hence they only can work for a limited period of time. Even in a RCV (Remote Controlled
Vehicle).It is completely and always controlled by human i.e. wherever it has to move the
user has also to move with it. So the RCV does not take any positive actions autonomously.

10.4 Designfor environment
Our Project Group is committed to reducing environmental impact at all stages of the life cycle
of our product. This is the guiding principle of the group's manufacturing activities.

65
Since each of the stages are closely interlinked in terms of environmental impact, continuous
efforts are required to make incremental improvements and to achieve technological innovation.
Our project group aims to make such efforts throughout its operations in order to continuously
deliver eco-conscious products to customers.
Further improvements in energy-saving performance during product use, and enhancement in the
reusability, recyclability, and collection system for either products or consumables.
1. Development and design
Basic policy
Our product is developed and designed to:
It is essential to apply at the design stage, environmental considerations for the entire life cycle
of a product. For certain key criteria in the product environmental assessments, target values are
set at the initial stage of development and design. Improvements must be achieved when
compared with those products of the previous generation.

66
Fig 10.5: Product impact Assesment flow :

2. Procurement
Basic policy
We check parts and materials that are used to make products, to ensure:
-friendly process.
In this way, we give priority to purchasing parts and materials.
3. Production
Basic policy
All manufacturing facilities of our group have ISO 14001 environmental management systems.
Products are manufactured within that global system with due consideration being given to:

67
4. Packaging and logistics
Basic Policy
We are committed to:
Reducing distribution and transport.
5. Use
Basic policy
Consideration for our customers' use of our products:
do not consume excessive energy; and our products can be used safely, conveniently and
comfortably. We also endeavor to disclose overall environmental information about products.
6 Collecting and recycling
Basis Policy
As considerations for the end of life of a product, we make efforts to:
The DFE analysis showed that the Cell p[hone oriented Robotic Vehicle can easily be recycled
and does not waste many materials. The motor and Microcontroller do not appear to be
specifically designed for this system and so they could potentially be used in other products. The
Plywood casing can be recast and the plastic parts can be recycled. The entire system was not
built to be disassembled because it is difficult to take apart and a seal has to be broken in order to
fix any internal parts. The chosen materials are robust, therefore it seems that it was meant to last
a long time without failure, but not be fixed after breaking.

13.3 Improvement.
1. IR Sensors
If IR sensors are used they can automatically detect & avoid obstacles.the robot goes
beyond line of sight. This avoids damage to the vehicle if we are maneuvering it from a
distant place.
2. Password Protection
Project can be modified in order to password protect the robot so that it can be operated only
if correct password is entered. Either cell phone should be password protected or
necessary modification should be made in the assembly language code. This introduces
conditioned access and increases security to a great extent.
3. Adding a Camera
If the current project is interfaced with a camera (e.g. a Webcam) robot can be driven
beyond line-of-sight & range becomes practically unlimited as GSM networks have a
very large range.

Conclusions
15.1 Conclusions
The prototype of the GSM based Generator Control device was efficiently designed. This
prototype has facilities to be integrated with a Generator thus making it truly mobile. The toolkit
accepts the SMS, stores it, validates it and perform specific operations. The SMS is deleted from
the phone each time it is read, thus making room for the next SMS.
15.2Group learning
We learnt how to work in a team with a team co ordination .We gained knowledge about our
project in deep. We also had knowledge on how to implement our ideas into a certain things. We
got to know about the components which we used in our projects in details. We also got to know
how to implement GSM modem with Microcontroller. 
Learn to break complex tasks and steps.
