The document describes a robotic vehicle project that uses RF technology for remote operation and a wireless camera for monitoring purposes. The robot can transmit real-time video wirelessly. It also has a temperature sensor that detects surrounding temperatures and sends the data via Bluetooth to a receiver and display. The robot is controlled using an ATMEL microcontroller and uses an RF transmitter and receiver to wirelessly transmit data over short ranges. Benefits include live video streaming while drawbacks include limited range and need for recharging batteries.

3. • The project is designed to develop a robotic
vehicle using RF technology for remote
operation attached with wireless camera for
monitoring purpose. The robot along with
camera can wirelessly transmit real time
video. This kind of robot can be helpful for
spying purpose in war fields , scientific
research etc.

8. Bluetooth module

9. Temperature sensing by LM35 using
ADC0804
• The temperature sensing device is fitted on the
robot and it senses the temperature of the
surroundings using sensor LM35 the data then is
sent to the ADC0804 that converts the analog
temperature into Digital and the digital data is
sent serially by the Bluetooth module HC05t
Transmitter to the Receiver where it is received
and displayed at the screen.
• All this is carried by using the controller by
ATMEL AT89C51.

16. RF BASED Receiver

17. • This RF module comprises of an RF Transmitter and an RF
Receiver. The
• Transmitter/receiver (Tx /Rx) pair operates at a frequency of 434
MHz.
– An RF transmitter receives serial data and transmits it wirelessly
through RF through its antenna connected at pin4.
– The transmission occurs at the rate of 1Kbps - 10Kbps.The
transmitted data is received by an RF receiver operating at the same
frequency as that of the transmitter.
• The RF module is often used along with a pair of encoder/decoder.
– The encoder is used for encoding parallel data for transmission
feed while reception is decoded by a decoder.
– HT12E-HT12D, HT640-HT648, etc. are some commonly used
encoder/decoder pair ICs.

22. Merits
• Real time Live video streaming.
• Less implementation cost.
• Compact in size
• Can operate at any time of the day.
• If the robot gets damaged any how still we
have the data. As the data is stored in the
home computer.

23. Demerits
• The operating range for the robot is limited to
100mtrs.
• It is designed for plane surfaces where it can
move very perfectly but the wheels will not
work on rough bases.
• The power requirement is fullfilled using 9v
batteries so when they get discharged they
need to be replaced.

24. • Implementation of serial communication over
a wireless link.
• Working with airdroid app efficiently.
• Efficient motion control of a robot.
