ABSTRACT:
Path Finder was sent to
Mars in 1998. This was a great achievement which detected the secrets of
“Mars”. This project deals with RF controlled robot. This robot is prototype
for the “Path Finder”.
This robot is controlled by
a RF remote. This can be moved forward and reverse direction using geared
motors of 60RPM. Also this robot can take sharp turnings towards left and right
directions. This project uses AT89S52 MCU as its controller. A high sensitive
induction type metal detector is designed using colpitts oscillator principle
and fixed to this robot. Also a wireless camera with voice is interfaced to the
kit.
When the robot is moving on
a surface, the system produces a beep sound when metal is detected. This beep
sound will be transmitted to remote place. Simultaneously the images around the
robot will be transmitted to remote place. User can monitor the images and
metal detection alarms on Television.
The
RF modules used here are STT-433 MHz Transmitter, STR-433 MHz Receiver, HT12E
RF Encoder and HT12D RF Decoder. The three switches are interfaced to the RF
transmitter through RF Encoder. The encoder continuously reads the status of
the switches, passes the data to the RF transmitter and the transmitter
transmits the data.
This project uses 9V
battery. This project is much useful for mines detection and surveillance
applications.
