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 mobile
Robot and the rem ....etc

1. INTRODUCTION

With the proliferation of portable electronic devices, power efficient data transmission has become increasingly important. For serial data transfer, universal asynchronous receiver / transmitter (UART) circuits are often implemented because of their inherent design simplicity and application specific versatility. Components such as laptop keyboards, palm pilot organizers and modems are few examples of devices that employ UART circuits. In this work, design and analysis of a robust UART architecture has been carried out to m ....etc

ABSTRACT
In this paper, several low power techniques, including low transition ASCII (LT-ASCII), that are particularly effective for the universal asynchronous receiver / transmitter (UART) circuits are proposed. Low power techniques, such as voltage scaling, clock gating, MT-CMOS and complete power shut down, are investigated to minimize the UART logic power in both continuous and idle modes of operation. The overheads circuitry required for each technique and penalties as ....etc

SERIAL COMMUNICATION STANDARDS

Serial Communication means Data can be Transmitted One bit at a time in series, is called serial Data Communication.

In Generally Serial Communication Standard buses are 3 types.
There are :
1.) USB (Universal Serial Bus)

2.) I^2C

Introduction
Due to it s relative simplicity and low hardware overhead (as compared to parallel interfacing), serial communications is used extensively within the electronics industry. Today, the most popular serial communications standard in use is certainly the EIA/TIA 232 E specification. This standard, which has been developed by the Electronic Industry Association and the Telecommunications Industry Association (EIA/TIA), is more popularly referred to simply as RS 232 where RS stands for recommended standard . In recent y ....etc

SERIAL COMMUNICATION BY USING UART



INTRODUCTION

The UART: What it is and how it works
A UART (Universal Asynchronous Receiver/Transmitter) is the microchip with
programming that controls a computer's interface to its attached serial devices.
Specifically, it provides the computer with the RS-232C Data Terminal Equipment
(DTE) interface so that it can talk to and exchange data with modems and other serial
devices. As part of this interface, the UART also:
Conve ....etc

LED BRIGHTNESS CONTROLLING USING SERIAL PORT



Interfacing with pc

Interfacing is done using RS232 DS-9 port which is connected to pc & microcontroller.
On port 3,at p3.0 & p3.1 the input signal is received.
TXD,RXD pins are also used in interfacing.

Sending signals from pc

To send signals from pc we need to make a software using vb .net .This signals will vary from 0 to 255.As per this signals the PWM will vary by duty cycle in microcontroller, resulting in a c ....etc
