 # Robotis Lab Release Notes
 
+0.2.0 (2025-10-28)
+------------------
+### OMY Sim2Real Imitation Learning Pipeline
+* Folder Structure Refactor:
+    * Tasks are now separated and organized into two categories:
+        * real_world_tasks – for real robot execution
+        * simulator_tasks – for simulation environments
+* Sim2Real Pipeline Implementation:
+    * Task Recording: Added functionality to record demonstrations for the OMY plastic bottle pick-and-place task in simulation.
+    * Sub-task Annotation: Introduced annotation tools for splitting demonstrations into meaningful sub-tasks, improving policy learning efficiency.
+    * Action Representation Conversion: Converted control commands from joint-space to IK-based end-effector pose commands for better real-world transfer.
+    * Data Augmentation: Added augmentation techniques to increase dataset diversity and enhance policy generalization.
+    * Dataset Conversion: Integrated data conversion to the LeRobot dataset format, enabling compatibility with LeRobot’s training framework.
+* ROS 2 Integration:
+    * Modified to receive the leader’s /joint_trajectory values using the robotis_dds_python library without any ROS 2 dependency.
+
 0.1.2 (2025-07-29)
-FFW BG2 Pick-and-Place Imitation Learning Environment
+------------------
+### FFW BG2 Pick-and-Place Imitation Learning Environment
 Built an imitation learning environment for cylindrical rod pick-and-place using the FFW BG2 robot.
 
 * Implemented the full pipeline:
