Mobile phone robot

ABSTRACT:

For many people robot is a machine that imitates a human—like the androids in Star Wars, Terminator and Star Trek: The Next Generation. However much these robots capture our imagination, such robots still only inhabit Science Fiction. People still haven't been able to give a robot enough 'common sense' to reliably interact with a dynamic world. The type of robots that you will encounter most frequently are robots that do work that is too dangerous, boring, onerous, or just plain nasty.

In fact, there are over a million of these types of robots working for us today. A study of robotics means that students are actively engaged with all of these disciplines in a deeply problem-posing problem-solving environment.

Our mobile phone robot consists of microcontroller ATMEL AT89C51; a DTMF decoder CM8870C which decodes the keypad signals and these signals are given to the microcontroller which will drive the dc motors using L293D driver. The direction of the robot will be selected by the key press from our handheld mobile phone.

The programming language used for developing the software to the microcontroller is Embedded/Assembly. The KEIL cross compiler is used to edit, compile and debug this program. Here in our application we are using AT89C51 microcontroller which is Flash Programmable IC.AT represents the Atmel Corporation represents CMOS technology is used for designing the IC.
