+# MR6D: Benchmarking 6D Pose Estimation for Mobile Robots
+
+This repository contains the **MR6D** dataset, introduced in the paper [MR6D: Benchmarking 6D Pose Estimation for Mobile Robots](https://huggingface.co/papers/2508.13775).
+
+MR6D is a novel dataset specifically designed for 6D pose estimation for mobile robots operating in industrial environments. It addresses the limitations of existing datasets that primarily focus on smaller household objects and robot arm manipulators.
+
+The dataset includes 92 real-world scenes featuring 16 unique objects across static and dynamic interactions. It captures challenges specific to mobile platforms, such as distant viewpoints, varied object configurations, larger object sizes, and complex occlusion/self-occlusion patterns. MR6D serves as a crucial benchmark for developing and evaluating 6D pose estimation methods tailored to the demands of mobile robotics.
