Nowadays, the use of various encoders in different industries has become inevitable, and with the rapid advancement of science and industry, the need for more accurate and reliable encoders is increasing. One type of encoder with maximum accuracy is the De Bruijn sequence-based encoder. However, these encoders face challenges in detecting bidirectional rotation. This paper introduces a novel approach for detection of two-directional movements based on De Bruijn sequences in precise automation applications. Traditional rotary encoders, employing De Bruijn sequences, have been effective in detecting single-directional movement; however, they necessitate an additional sensor to capture bidirectional movement. The proposed novel methodology eliminates this need by enhancing De Bruijn sequence-based detection, enabling the identification of both clockwise and counterclockwise movements without the requirement for supplementary sensors. This advancement holds significant implications for automation systems, offering a more streamlined and efficient solution for angular movement detection. Improved capability of De Bruijn sequence-based encoders to discern bidirectional movement makes them particularly valuable in robotics and automation applications.
