Design of an intelligent security robot for collision free navigation applications

摘要

Robotics industry has replaced human efforts gradually in performing rather difficult tasks. A very pertinent aspect of an intelligent security robot is to reach the goal safely by avoiding unknown obstacles in an unknown environment. In this paper we have developed an embedded C program code to design an intelligent robot which can overcome the obstacles coming in its way. We have made use of three infrared sensors to detect the obstacles via the IR communication technique. The IR transmitter sends out infrared radiation in a direction which consequently bounces back on coming across the surface of an object and thereafter is picked up by the IR receiver. Authors have applied a multi sensor integration technique to sense the obstacles using an LED based IR transmitter and receiver module integrated with the 8051 micro controller which permits collision free navigation of robots.
