Development of a Real-Time Task Editable Service-Oriented Security Robot

Abstract

Robots are widely used in modern industrial manufacturing, in households, in entertainment, and in the security sector. Recently, because of the complexity of household-robot missions remotely controlled by the host, the development of a real-time task editable service-oriented security robot that may efficiently execute routine missions by avoiding advance instruction is necessary In this paper, an intelligent and interactive security robot is developed. In order to remotely manipulate the robot’s movements, both the PC-base’s TCP/IP protocol and the Web-base with an active server page (ASP) function via an access point (AP) are adopted. To facilitate targeted functions, interactivity in conjunction with high quality sensors plays an essential role. To avoid colliding with a barrier, an ultrasonic sensor is installed on both sides of the security robot. By using infrared sensors, the electric charge station can be detected. Additionally, electrical devices used in a home equipped with RF receivers can be remotely manipulated by receiving signals transmitted from the RF transmitter of the security robot. Moreover, for security purposes, an infrared sensor installed in the security robot is used to detect a house invasion by an unwanted intruder, causing both the alarm and the web-camera to be triggered simultaneously. Here, in order to deal with all signals, a 8051 microchip connected to the robot’s mother board is used. The 8051 microchip will receive the signals (Web-Cam system, the infrared sensor, the body infrared sensor, and the ultrasonic sensor) and trigger the devices (Web-Cam system’ motor, wheel’s motors, alarm system, and RF-transmitter) Consequently, a prototype security robot has been manufactured and successfully tested in the laboratory
