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 through space rather than being guided through an optical cable. These beams of li ....etc

OBJECTIVE
A summer internship report is a documentation of a student s work a record of the original work
done by the student in the summer internship of 8 week duration.
The objective of this document is to provide a set of guidelines that help a student to prepare the
report to satisfy the requirements of internship report.
The guidelines are general. Student may follow these else any better/ innovative way of presenting
the work done during intern in a form of report is always welcome.
Following is the sequence heading of summer int ....etc

I am using UART for communicating 8 modules having LPC2148 microcontroller as a slave with another module having LPC2148 as master.But I am finding a constraint of wire length(I have read some articles on net which suggest a wire length of 2.6 mtrs for a baudrate of 56000bps) Can I replace this with MODBUS communication ?If yes where can I get information about modbus? ....etc

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
