Abstract:In this paper, a non-contact multi-degree-of-freedom (multi-DOF) attitude measurement method for spherical joints based on magnetic sensing is proposed, which realizes attitude detection of spherical joints without introducing new contact force and shows advantages of easy installation, low cost, and strong practicability. The sensor system utilizes theoretical derivation, data fitting, and machine learning methods to establish a function mapping model between magnetic field variation and Euler angles of spher… Show more
