SLAM (Simultaneous Localization and Mapping) of the underground robot is a hot research topic at present. But the research on improving the precision and robustness of laser SLAM in underground complicated conditions is still insufficient. The traditional laser SLAM method has the problems of rapidly increasing cumulative error. poor robustness of the rotation process and high error r... https://miabellesbabyes.shop/product-category/subscribfy_subscription_product/
