Collision Avoidance Concept of UAV During Fire Related Incident for SAR Missions

Abstract

Current trend in Search and Rescue mission begins to incorporate the use of Unmanned Aerial Vehicle or drone which means that for each type of catastrophes, a specific payload is required. The main target for this project is to develop a new payload which is an active solution for flame-based collision avoidance system (CAS) concept so that a drone can manoeuvre very closely in a flammable related area without harming itself. A hex-copter drone type will be used as a platform for this proposed system. The proposed payload is developed using off-the-shelf sensors, integrated using Arduino with Pixhawk Cube is used as the flight control system (FCS) and remotely control by using 8-channels remote controller (RC). Static test (propeller is not connected) was performed to evaluate the response of all 6 motors in order to see it responses when the payload is being triggered. The preliminary result shows that the ground control RC command can be bypass successfully by maintaining some level of control of the motor. Extensive study will be carried out later in the phase to ensure the correct response before actual flight test can be carry out. In conclusion, this flame-CAS payload shows a promising result that can be implemented as an alternative manoeuvring aid to ensure safety of the drone deployed during fire related SAR operation provided an efficient control scheme can be developed.
