RoboAct: Robot Action Learning Framework

πŸ“‘ Paper | 🌐 Project Page | πŸ’Ύ Released Resources | πŸ“¦ Repo

We release the raw data for our processed Motion dataset, adopted from the original RT-X (Open X-Embodiment) dataset from Google DeepMind team.

The data format for each line in the robot_motion_sequences.jsonl is as follows:

{
  "episode_id": <unique identifier for the episode>,
  "robot_type": <robot platform used for data collection>,
  "task_description": <natural language task instruction>,
  "observation_space": {
    "image_primary": <path to primary camera image>,
    "image_wrist": <path to wrist camera image>,
    "state": <robot proprioceptive state vector>
  },
  "action_sequence": [
    {
      "action": <7-DoF action vector>,
      "timestamp": <action timestamp>
    },
    ...
  ],
  "source": <original RT-X dataset subset>,
  "difficulty": <easy/medium/hard>,
  "meta": <additional metadata>
}

Some of the action_sequence entries are incomplete due to episode truncation during collection. These are marked in the metadata.

*Note: Due to the heterogeneous nature of robotics data from multiple labs, some action spaces have been normalized to a common format. Original action definitions are preserved in the metadata.
