LerobotDS
收藏资源简介:
该数据集是使用LeRobot工具创建的机器人领域数据集,专门用于机器人学习任务。数据集包含1个完整的episode,共计896个时间步(帧),对应1个任务。数据以parquet文件格式存储,总大小约100MB,同时包含约200MB的MP4格式视频文件,视频帧率为30fps。数据集仅提供训练集划分。核心数据内容包括:机器人的动作指令(action)和当前状态观测(observation.state),两者均为6维浮点向量,具体控制机器人肩部平移、肩部抬升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置。观测模态还包括来自顶部相机(overhead_camera)的RGB视频流,分辨率为480x640。此外,数据集提供了丰富的时间与序列元数据,如时间戳、帧索引、episode索引和任务索引,用于标识数据在时序和任务上下文中的位置。该数据集适用于机器人模仿学习、强化学习或行为克隆等任务的训练与评估。
This robotics dataset was constructed using the LeRobot toolkit, and is exclusively tailored for robotics learning tasks. The dataset contains 1 complete episode, totaling 896 timesteps (frames), corresponding to 1 single task. The core data is stored in Parquet file format, with a total size of approximately 100 MB, and also includes around 200 MB of MP4-format video files with a frame rate of 30 fps. Only the training split is provided for this dataset. The core data content includes robot action commands (action) and current state observations (observation.state), both of which are 6-dimensional floating-point vectors that specifically control the robot's shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position. The observation modalities also include an RGB video stream from the overhead camera (overhead_camera), with a resolution of 480x640. In addition, the dataset provides rich temporal and sequential metadata, such as timestamps, frame indices, episode indices, and task indices, which are used to identify the position of the data within the temporal and task context. This dataset is suitable for training and evaluation of tasks such as robot imitation learning, reinforcement learning, or behavioral cloning.
