Hand gesture recognition technology
based wireless surveillance bomb diffusing robot with mobile jamming TECHNIQUE
USING MEMS TECHNOLOGY
ABSTRACT:
This is an interesting robot that
can be controlled by hand gestures and 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
mobile phone signal isolator is interfaced to the kit.
When
the robot is moving on a surface, the system produces a beep sound when Bomb is
detected. Simultaneously a signal is fed to the jammer section to switch on the
jammer. This jammer diffuses the bomb by jamming the mobile signal of GSM or
CDMA or 3G networks.
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.
