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.

Introduction1.1 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 Design for 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: comply with laws and regulations of the various countries and regions where sold;

be compact and lightweight to conserve resources;

achieve the top levels of energy conservation performance in the industry;

manage hazardous chemical substances

be easily recycled at the end of life

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.

Hazards during production or use

Size, weight and recyclability of packaging materials

Material labeling, compliance with related laws and environmental labels

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: they do not contain hazardous materials, and

they are made via an eco-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: ensuring efficient use of materials, energy, and water resources, etc.;

reducing pollutants released into the atmosphere and wastewater;

preventing the generation of waste; and

Recycling waste generated.

67

4. Packaging and logistics Basic Policy We are committed to: reducing product packaging and waste where possible; and

Reducing distribution and transport.

5. Use Basic policy Consideration for our customers' use of our products: they 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: Collect and recycle products and consumables at end of life

Design products so that they can be easily recycled.

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.
