收藏资源简介:
该数据集是使用LeRobot创建的机器人数据集,专门用于跟随者机器人(so_follower)任务。数据集包含100个episodes,总计47181帧,覆盖1个任务。数据以parquet文件格式存储,总数据文件大小为100MB,视频文件大小为200MB。数据集特征包括:动作(action)——表示6个关节位置(肩部平移、肩部提升、肘部弯曲、腕部弯曲、腕部旋转、夹爪位置);观测状态(observation.state)——同样为6个关节位置;两个摄像头图像观测(observation.images.camera1和camera2)——均为480x640分辨率、30fps的视频,编码为av1,无音频;以及时间戳、帧索引、episode索引等元数据。数据集适用于机器人控制、模仿学习或强化学习研究。
This dataset is a robot dataset created using LeRobot, specifically for the follower robot (so_follower) task. It contains 100 episodes, totaling 47,181 frames, covering 1 task. The data is stored in parquet file format, with a total data file size of 100MB and video file size of 200MB. Dataset features include: action – representing 6 joint positions (shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, gripper position); observation.state – also 6 joint positions; two camera image observations (observation.images.camera1 and camera2) – both 480x640 resolution, 30fps videos, encoded as av1, without audio; and metadata such as timestamps, frame indices, and episode indices. The dataset is suitable for robot control, imitation learning, or reinforcement learning research.
