Human following behavior of an autonomous mobile robot using light-emitting device

The purpose of this study is to develop an autonomous mobile robot which can follow a human being. The robot with a camera looks at a human carrying a light-emitting device. The device consists of two LEDs, and between these two LEDs the direction from the position of the LED is captured on the image; the robot can then follow the trajectory of the human. The main features of the approach are the camera's pan and on-off flashing LEDs. In this paper, the method used and result of a primary experiments are presented.
