What is Rescue
Human rescuers have very
short time (about 48 hours) to find trapped victims in a
collapsed structure, otherwise the chance of finding victims
still alive is nearly zero. In such a critical situation
technology can make a great help for rescuers. Intelligent
mobile robots and cooperative multi-agent robotic systems can
be very efficient tools to speed up search and rescue
operations. Rescue robots are also useful to do rescuing jobs
in situations that are hazardous for human rescuers. They can
enter into gaps and move trough small holes that is impossible
for humans and even trained dogs. Robots should explore in
collapsed structure, extract the map, search for victims and
report the location of victims in map and way that rescue team
can reach him/her.It can also place a small package containing food, drugs and a
communication device near the victim.
Our preliminary aim in this
project is to build an autonomous robot which could be able to
hang around in an unstructured environment and search for victims.
To do this job we are facing up with many different challenges
that most important of them are listed below:
Mechanical Challenge :
It is not easy to design a mechanical system to be
able to hang around easily in unstructured environment of a
collapsed building. Besides it must be robust against
hazards and be able to catch its normal position if turned
over while moving on a debris.
Robot should avoid of
collision for two reasons. First for avoiding dangerous
locking situations for robot, and second for preventing to
make more damage in environment. Obstacles are static or
dynamic and have different shapes and characteristics.
Victim Detection :
This is a very difficult task especially in
unstructured environment of a collapsed building. The only
signs of a victim are his/her moaning voice, body
temperature, wearing texture, body scent.
Path Planning :
To determine victim position for human rescuers,
robot has to be able to determine its position. Also it
should be able find its path in ruins to search for victims
and go out of structure after end of its mission.
