Abstract
Studies on mobile robots to support our daily lives are very active, and several approaches are reported. We are developing an autonomous mobile robot named TRACY3 for human following behavior using infrared light tracing approach. Our goal is that TRACY3 be always behind its human master and plays a role of a friend, a servant, or a mechanical pet. Control mechanism of TRACY3 is based on direction control with LED sensor and speed control with ultrasonic sensor. The LED sensor detects infrared light coming out from the IR device attached to the waist of human body. The paper presents the basic control mechanism of TRACY3,and shows the result of tracing experiments.
