GSM BASED WIRELESS ROBOT
[attachment=66714]
INTRODUCTION
Conventionally Wireless-controlled Robots use RF circuits, which have limited working range, limited frequency range and limited control. Use of a mobile phone for robotic control can overcome these limitations. It provides the advantage of robust control, working range as large as the area of the service provider, no interference with other controllers. Although the appearance and capabilities of robot vary vastly, all robots share feature of a mechanical, movable structure under some form of control. The control of Robot involves three distinct phases: perception, processing and action. Generally, the preceptors are sensors mounted on the robot, processing is done by the on-board microcontroller or processor, and the task is performed using motors or with some other actuators. In this project the robot is connected to gsm modem which is controlled by user mobile phone. With the help of AT commands we can move our robot in desired direction as per our requirement.
HARDWARE USED
1. 89S52 Microcontroller
2. Max 232 IC.
3. Voltage regulator 7805.
4. Diode IN4007
5. GSM Modem.
6. Some other components to produce interrupt
SOFTWARE USED
Keil u-Vision 3.0
Keil Software is used provide you with software development tools for 8051 based microcontrollers. With the Keil tools, you can generate embedded applications for virtually every 8051 derivative. The supported microcontrollers are listed in the ยต-vision.
THEORY OF OPERATION
In this project we interfaced 8051 microcontroller with SIM 300 GSM modem to decode the received message and do the required action. The protocol used for the communication between the two is AT command.
The microcontroller continuously checks for SMS to take the decision for controlling the DC motor.
AN INTRODUCTION TO 8051 MICROCONTROLLER
When we have to learn about a new computer we have to familiarize about the machine capability we are using, and we can do it by studying the internal hardware design (devices architecture), and also to know about the size, number and the size of the registers
