Summary:A novel detachable rotary magnetic encoder is proposed, developed, and validated in this study, demonstrating excellent precision and potential for subaqueous applications, regardless of underwater or airborne environments. Utilizing Hall sensors as sensing elements, the encoder generates orthogonal signals relative to incremental disk rotation and incorporates a filter to enhance the signal-to-noise ratio (SNR). Experimental validation confirms the high positioning accuracy and repeatability of the system, with an accurate response to underwater fluctuations of 0.1°. Considering the characteristics of this measurement system, its prospects at underwater robotic arm joints are foreseen, thereby driving the advancement of underwater precision control technology.
