Reasons for choosing this project :-

1. The goal of this research was to provide a low cost rescue robot for human detection in a disaster environment.

2. Though, the existing Urban Search and Rescue Robots are equipped with various sensors, but the problem with them is the cost.

3. The sensors used in the development of this project are easily available and cost effective.

Project details :- In this project, a new method for detecting surviving humans in destructed environments using simulated autonomous robot is proposed.

The robot uses two levels of sensing in order to achieve higher cost-effectiveness in the detecting process in terms of the actual cost of equipment, the processing cost, the communication cost, the storage cost, and the power cost.

The first level is a PIR sensor used with a temperature sensor, that is used as the primary sensor in order to detect the existence of living humans in a scene.

The second level is a human body shape sensor. This level uses low-cost web camera in order to confirm the existence of a human shape.

The robot is assumed to be equipped with a simple Temperature sensor in order to detect fire in Rescue scenario and a wireless communication link in order to communicate with the rescue team whenever a need arises.

Software & Hardware used :-

Windows 2000 & onwards version Embedded c Keil software Proteus software

The Robot is equipped with following hardware :

A PIR sensor. An ultrasonic sensor. A Temperature sensor. A Microcontroller unit. A webcam. Motor.

Materials Availability - Cost & Procurement Strategy :-

The instruments used in this project are common electronic devices and easily available.

Low cost and easy to use.

Lab setup:-

Hardware (to connect microcontroller) Pony Prog (Serial, Parallel) AVRdude (supports many hardware) USB-ASP (USB)

Code Vision AVR (CVAVR):

An IDE has following functions: Preprocessing Compilation Assembly Linking Object Translation

Applications

1. In military applications to detect the presence of human being.

2. In Rescue operations where human reach is not possible.

3. In War fields, to control unmanned aerial vehicles(UAV).

Future enhancement :-

Since the system developed is a low cost system therefore it has a wide future scope.

Though many systems with a wide range of sensors have been developed, but there are many problems faced by them such as cost, size, environment difficulties etc.

Future works:-

Detail study about the microcontroller to be used.

Interfacing the peripheral devices with microcontroller.

Detail study on the sensors to be used and their interfacing.

Connection of the circuits used with sensors and microcontroller unit.
