STRUCTURE OF ENHANCING ODOMETRY MEASUREMENT FOR ROBOT CLEANER AND ROBOT CLEANER USING THE SAME

摘要

A position detection structure and a robot cleaner using the same are provided to reduce imprecision due to a slip phenomenon in position detection by detecting the moving distance of the robot cleaner using an encoder of a auxiliary wheel. A position detection structure of a robot cleaner comprises an auxiliary wheel(110), an adhesive unit(120), and a detection unit(130). The auxiliary wheel supporting the robot cleaner includes a predetermined number of detection reference units corresponding to the outer periphery of the auxiliary wheel. The adhesive unit attaches the auxiliary wheel to the robot cleaner. The detection unit obtains traveling information of the robot cleaner by detecting position change of the detection reference unit corresponding to the rotation of the auxiliary wheel.
