Abstract

We propose a method for an indoor mobile robot to track user with infrared transmitter. Several infrared receivers attached around by the mobile robot enable the robot to determine the moving direction by comparing the received signal patterns. The cost of the proposed system is not only cheaper than ultrasonic system, image signal processing, RFID, and RSSI method, but also robust against environment change because any complex algorithm is not necessary. In the mobile robot, ultrasonic sensors are equipped to avoid obstacles located in the moving direction, and a simple algorithm is embedded to avoid the case of poor signal reception.
