MOTIVATION• Cell phone is not only device to communicate with other

persons. It is very much useful to communicate and command the machine also.

• In this busy schedule, man can get his work accomplished through a robot even in his physical absence from any place through SMS using a cell phone.

• This product has many applications in medical as well as industrial and defence system.

• Robot can travel to all those places where it is not possible for a human to evolve.

OBJECTIVE OF THE PROJECT

• The objective of this project is to control and operate the robot with the help of cell phone through SMS technique.

• To provide the advantages of robust control, working range as large as the coverage area of the service provider with no interference with other controllers .

PROBLEM STATEMENT

• Conventionally, wireless-controlled robots use RF circuits, which have the drawbacks of limited working range, limited frequency range and limited control.

• So we developed a product which is user friendly as well as robust in controlling with wider working range and faster operating speed.

LITERATURE SURVEY Points suggested by [1] GSM based Robotic Car by Awab Fakih, Jovita Serrao

Conventionally, wireless-controlled robots use RF circuits, which have the drawbacks of limited working range, limited frequency range and limited control.

Use of a mobile phone for robotic control can overcome these limitations.

It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls.

A remote control vehicle (RCV) is often a radio controlled device which is always controlled by a human and takes no positive action autonomously.

A typical Robotic Vehicle is capable of traveling over various terrains and traversing obstacles. In one embodiment, the design in this work, includes a body having four drive wheels coupled to the ends . The wheels are selectively powered to propel the vehicle. The use of Robots is highly recommended for Industries especially for safety and productivity reasons.

INTRODUCTION

• Cell phone is not only a device to communicate with other persons but it is very much useful to communicate and command the machine also.

• The appearance and capabilities of the robot vary vastly but they share the feature of mechanical and movable structure under some form of control, as this robot is being controlled by giving a SMS by our mobile phone.

• The robot prototype has mainly three phases: 1) Perception 2) Processing 3) Action
