Microcontroller Based PC Controlled Robot for Detecting Human Presence

Abstract

Our project’s main objective is to contribute to a human cause. Human detection in an unmanned area can be done efficiently by a robotic system. The task of identifying human being in rescue operations is difficult for the robotic agent but it is simple for the human agent. In order to detect a human body, an autonomous robot must be equipped with a specific set of sensors that provide information about the presence of a person in the environment around. This alive human body detection system proposes two levels sensing system: First Level is the PIR sensors to detect the existence of the living human beings and Second Level is the distance sensor to measure the distance of the human body from the robotic vehicle. Temperature sensor has been used as a high temperature alert to prevent the robot from getting damaged. The robot is made a PC controlled vehicle by using wireless technology. The communication between personal computer and microcontroller is taking place by the means of ZigBee Transceiver. As it is a wireless robot it can be easily mobilized and controlled. Hence, wireless communication increases the effectiveness of the detection process. Whenever any human motion is detected, an alarm is raised. This system has the potential to achieve high performance in detecting movement of humans in devastated environments relatively quickly and cost-effectively.
