Abstract

Real time embedded systems are time-critical systems that are hard to implement as compared to traditional software, due to large numbers of conflicting requirements. This project describes an application of advance modeling techniques to improve the development of embedded systems. In our project we are going to explain one of the most successful applications of a robot called the tele-operated intelligent mobile robot in which a couple of mobile phones are connected and used as the transmitting and reception media. The main objective of the project is to develop the robot using embedded technology to reduce the complexity in design and control the movement of robot using cell phone.

This is implemented using DTMF technology. A cell phone is connected to the robot. When a call is made from another cell phone to the one attached to the robot, automatically the call gets lifted and the robot starts acting according to the commands given by the caller. The microcontroller is interfaced with dc motors through the line driver.

The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmel's high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pin out. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications. In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes.
