This dataset is a robotics learning dataset specifically developed for 3-degree-of-freedom (3-DOF) planar arm robots performing the Push-T task in the Gazebo simulation environment. It consists of 21 training episodes, totaling 24930 frames with a sampling frequency of 10 fps. The data is stored in Parquet format, with a total data file size of 100 MB and a video file size of 200 MB. The dataset includes the following features: observed RGB images with a resolution of 96×96 pixels, observed states (three joint positions: joint_1, joint_2, joint_3), actions (three joint control commands), next-step rewards, completion flags, success flags, timestamps, frame indices, episode indices, and more. This dataset was generated by the LeRobot project and is applicable to research in robotic reinforcement learning and imitation learning.
