Live human detection and alerting robot.

Hello friends...
A remotely controlled tracked wheel robotic platform is selected for the
main carrier. The reasons for this selection are:
- An autonomous robot can get stuck somewhere in the debris and it may not be
rescued by the team because of the lack of manual control.
- A wired control robot is not practical because of the need for a long wire which
can tangle anywhere in the debris and the robot can be operational.
- Wireless remote control will have a shorter distance under collapsed building but
manual control of the robot is valuable anyway and rescue team can enter the
disaster area to some extent and utilize the robot from there on.
- A tracked wheel platform is selected because wheels are not practical to operate
in such disaster areas but tracked robot can move over small obstacles better.
The robot carries a wireless camera which can transmit live video and audio
in low light conditions to the rescue team outside the vicinity in a safe place. Live
video is transmitted to any Android device (cell phone or laptop) so these can
easily be found anywhere in the world. Thus, human detection is easily carried out
by the research personnel.
Human detection module of the robot is mainly a PIR sensor controlled by
an Arduino microprocessor. When a human is present within the range of the
sensor (4-5 meters) it creates a detection signal (a digital pin goes high) which is
processed by Arduino and a red signal LED is lit on to indicate the detection. The
PIR sensor can detect motion and keep signaling (retriggering) but it will stop
when motion stops. This is why we have a camera onboard the robot. The human
detection module also has infrared lighting. The purpose of these LEDs is to
provide lighting in low or no light conditions for the camera.
Hope it helps you...
