收藏资源简介:
该数据集基于 LeRobot 平台构建,用于机器人操作任务,具体任务为“摇动烧杯并移动到冰箱”(task6-shake-beaker-and-move-to-fridge)。数据使用 mobileai_robot 机器人采集,包含 300 个演示片段(episodes),共计 182759 帧,帧率为 30 FPS。每个样本包含 16 维动作向量(左右手臂各 6 个关节位置及 1 个移动关节位置,加上线速度和角速度)和 16 维观测状态(与动作维度相同)。同时提供三个视角的 RGB 视频观测:高摄像头(cam_high)、左腕摄像头(cam_left_wrist)和右腕摄像头(cam_right_wrist),视频分辨率为 480×640,采用 H264 编码,无音频。此外还包含时间戳、帧索引、片段索引等元数据。数据集适用于机器人模仿学习、示教学习、操作技能迁移等任务,训练-测试划分采用前 300 个片段全部作为训练集。
This dataset is built on the LeRobot platform for a robot manipulation task, specifically shake beaker and move to fridge (task6-shake-beaker-and-move-to-fridge). The data is collected using the mobileai_robot, containing 300 episodes with a total of 182,759 frames at 30 FPS. Each sample includes a 16-dimensional action vector (6 joint positions for each arm, 1 mobile joint position, plus linear and angular velocities) and a 16-dimensional observation state (same dimensions as action). It also provides RGB video observations from three camera views: high camera (cam_high), left wrist camera (cam_left_wrist), and right wrist camera (cam_right_wrist), with a resolution of 480×640, encoded in H264, and no audio. Additionally, metadata such as timestamps, frame indices, and episode indices are included. The dataset is suitable for tasks like robot imitation learning, teaching learning, and manipulation skill transfer. The training-test split uses all 300 episodes as the training set.
