Subsequently, a slip estimation algorithm based on dynamically extending Q-learning (DEQ) was proposed, and several estimation strategies were tried for different states. In addition, a faux-Gaussian reward function was designed to provide feedback to the strategies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>The experimental results show that the DEQ method performs better than the theoretical calculation method.
