Learning such models is challenging due to process variability, data requirements, and the irreversible nature of grinding. We proposes a cutting-surface-aware Model-Based Reinforcement Learning (MBRL) method using a geometric cutting model. To address deviations from real data due to removal resistance, two strategies are employed: (1) limited real-world data to learn a residual model, and (2) large-scale simulation data with volume constraints to develop a sim-to-real transferable diffusion-based planner. Simulations and real-world experiments confirm the method&#8217;s effectiveness in automating robotic grinding.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<div class=\"block-list-appender wp-block\" tabindex=\"-1\" contenteditable=\"false\" data-block=\"true\">\n<div class=\"block-editor-default-block-appender\" data-root-client-id=\"\">\n<p class=\"block-editor-default-block-appender__content\" tabindex=\"0\" role=\"button\" aria-label=\"\u30c7\u30d5\u30a9\u30eb\u30c8\u30d6\u30ed\u30c3\u30af\u3092\u8ffd\u52a0\">\u00a0<\/p>\n<\/div>\n<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Prof. Takamitsu Matsubara gave a lecture in November.
