Abstract: The main objective of robotic research is to aid industrialism, making human lives convenient and flexible with the use of robots. This work addresses a scenario where a mobile robot tracks and follows a human. Some of the conventional methods such as Neural network, color skin probability map, Heuristic rule and Bayesian decision theory are used in this work. The real-time face detection module, based on a two-dimensional color model in the YUV color space is selected over the traditional skin color model in a three-dimensional color space. A modified CAMSHIFT tracking mechanism in a one-dimensional HSV color space is developed and implemented onto the mobile robot. In addition to the visual cues, the tracking process considers sixteen sonar-scan and tactile sensor readings to generate a robust measure of the person's distance from the robot. The proposed approach is orientation invariant under varying lighting conditions and under natural transformations.
