2. Why micro controller is used?
Micro controller contains micro processor,
memory (RAM & ROM),I/O interfacing circuits
and a peripheral devices such as A/D
converter,serial I/O,timer etc.
It has many bit handling instructions.
Less access times for built in memory and I/O
devices.
Micro controller based system requires less
hardware reduction PCB size and increasing
reliability.
3. Power supply unit
Initially power supply are design to convert
high voltage ac mains ac to suitable low volt-
age supply for electronics circuits and other
devices. A power supply can by broken down
in a series of blocks, each of which perform a
particular function. A DC power supply which
maintain the output voltage constant irrespec-
tive to the ac main fluctuation or load varia-
tions is known as “Regulated DC Power Sup-
ply”.

5. Working of RF based robotic car
The RF module, as the name suggest,
operates at the radio frequency. The
corresponding frequency ranges between
30kHz to 300kHz. This RF module comprises
of an RF transmitter and RF receiver.
The transmitter/receiver (Tx/Rx) pairs
operates at a frequency of 434 MHz.
The RF module has been used in conjunction
with a set of four channel encoder / decoder
ICs.
6. Working:-
The encoder converts the parallel input(from
the remote switches) into the serial set of sig-
nals.
These signal are serially transmit through RF
to the reception point.
The decoder is used after the receiver to de-
code the serial format and retrieve the original
signal as output.
