ABSTRACT:
A rescue
robot is a robot that has been designed for the purpose
of aiding rescue workers. Common
situations that employ rescue robots are mining accidents, urban disasters,
hostage situations, and explosions. Rescue robots were used in the search for
victims and survivors after the September
11 attacks in New York. The
benefits of rescue robots to these operations include reduced personnel
requirements, reduced fatigue, and access to otherwise unreachable areas. Robotic search
and rescue is useful since robots may be deployed in dangerous environments
without putting human responders at risk. This project is a prototype which is widely used for
military applications.
PIR sensor is used to detect
human. A Passive Infra Red sensor (PIR sensor) is an electronic device which
measures infrared light radiating from objects in its field of view. Apparent
motion is detected when an infrared source with one temperature, such as a
human, passes in front of an infrared source with another temperature, it
detects. It acts as a motion detector.
This robot uses RF
technology controlled by 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. Also a wireless camera with voice is interfaced to the kit.
The
RF modules used here are STT-433 MHz Transmitter, STR-433 MHz Receiver, HT12E
RF Encoder and HT12D RF Decoder. The 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.
