The Robot control using the wireless communication and the serial communication



Executive Summary
The NASA Robotics Alliance Cadets Program is being designed to be implemented at a
very low start-up cost, and to make this goal obtainable, the program is being developed
using low to no cost components from already developed, well-tested and robust
engineering testbeds.
In this project we are trying to establish both wireless communication between the mob ....etc

Advantages of digital communication system over analog communication system
Communication systems
 The block diagram on the top shows the blocks common to all communication systems
Remember the components of a communications system:
 Input transducer: The device that converts a physical signal from source to an electrical, mechanical or electromagnetic signal more suitable for communicating
 Transmitter: The device that sends the transduced signal
 Transmission channel: The physical medium ....etc

Respected Sir!

Myself Jigar B. Chaudhary. Recently I m doing my M.tech in Communication System Engineering. My first year is completed & my dissertation is going to start. So I request you sir to give me some dissertation topics based on VLSI+COMMUNICATION.Will you please suggest mereliable sources from where i can find the topics of my interest. My dissertation will start within 15 days.

Thank You Sir!!!

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

The development of a GSM automatic power meter reading (GAPMR) system is presented in this paper. The GAPMR system is consists of GSM digital power meters installed in every consumer unit and an electricity ebilling system at the energy provider side. The GSM digital power meter (GPM) is a single phase IEC61036 standard compliance digital kWh power meter with embedded GSM modem which utilize the GSM network to send its power usage reading using short messaging system (SMS) back to the energy provider wirelessly. At the power provider side an eb ....etc
