Design And Implementation Of Dual Band Antenna Based Unmanned Vehicle For Search And Rescue Operations

Abstract

In the event of large crisis, a primordial task of the search and rescue services is the searching for human survivors on the incident site, which is a dangerousand complex and task. The remotely operated Search and Rescue (SAR) robots offers a valuable tool to save human lives and to speed up the searchand rescue process. The Small Unmanned Ground Vehicle is designed to enter small enclosures, hazardous environments and Urban SAR operations such as location and positioning of victims trapped in structural collapse, mines and tragic accidents.
A new dual band antenna is designed and implemented for GPS and GSM frequencies (1.2 GHz and 2.1 GHz), which is used for communication and navigation of Unmanned Vehicle. The GSM module connected can do the required tasks like locomotion of an unmanned vehicle in all the directions and location of victims through camera by sending commands from cell phone. Digital camera module updates the surrounding location to the user. Temperature and Humidity sensor detects the temperature and humidity of surroundings. GPS module present in GSM module will help to locate the survivors and live location of UGV. In case of disaster, temperature and humidity values exceed threshold values. The results obtained show that the unmanned vehicle could locate the victims through proper human-machine interaction.
