Application of Radio Frequency Controlled Intelligent Military
Robot in Defense
ABSTRACT:
The term “Embedded” itself represents an inclusion of several independent
devices in to a single chip, which is also called a system on chip. With the
invention of VLSI technology it became possible to develop high speed, low cost,
low power, and small in size type integrated circuits. The Micro controller, that
used for this purpose is called IBP (Itty Bitty Processor) or embedded processor.
The multi task oriented systems that cause time delays, which may be
inefficient in some application, in such case, the micro controllers which can play
an important role as an embedded system design is more suitable one. Here, we
design a general purpose embedded system application “RF(433MHZ) controlled
Robot” is the evidence for the efficient use of automation, and is constructed
around the microcontroller and RF-433MHZ is (Radio Frequency).
Our aim of in this project is we control our robot through our RF by Switch
commands to the RF Transmitter and then pass the commands in our RF
Transmitter can have command like forward, backward, left, right operations can
be done and wirelessly control robot position through RF interfacing with 4-
switches.
In receiver section RF receiver can receive the commands from the RF
transmitter .Robot can move according to the commands.
This project uses regulated 5V, 750mA power supply. 7805 three terminal
voltage regulator is used for voltage regulation. Bridge type full wave rectifier is
used to rectify the ac output of secondary of 230/18V step down transformer.
