The authors developed miniature robots and proposed a position and angle measurement method using landmarks. The robot carries position sensitive detectors, the three lasers are used as the landmarks, and the method is suitable for an autonomy mobile robot. The measurement area depends on the length of a linear stage which carries the landmark. This paper is the 2nd report of the proposed method, and presents preliminary experimental results and evaluates the accuracy of the proposed measurement. The accuracy of the landmarks affects the accuracy of the measurement
