资源简介:
该数据集是一个用于机器人学习的双臂机器人数据集,使用LeRobot工具创建。数据集包含3个episodes,总计895帧,数据以30fps的帧率采集。主要特征包括:12维的动作向量(控制右臂和左臂各6个关节的位置,包括肩部、肘部、腕部和夹爪),12维的观测状态向量(反映机器人关节的当前位置),以及三个视频观测——顶部RealSense彩色摄像头、右侧腕部摄像头和左侧腕部摄像头拍摄的视频(分辨率均为480x640,3通道,AV1编码)。此外,数据集还包含时间戳、帧索引、episode索引、任务索引等元数据。数据集适用于机器人控制、模仿学习或强化学习任务,特别针对双臂机器人的操作场景。数据以parquet文件格式存储,视频以mp4格式存储,总数据大小约为300MB(数据文件100MB,视频文件200MB)。
This dataset is a dual-arm robot dataset for robot learning, created using the LeRobot tool. It contains 3 episodes, totaling 895 frames, collected at a frame rate of 30fps. Key features include: a 12-dimensional action vector (controlling the positions of 6 joints each for the right and left arms, including shoulder, elbow, wrist, and gripper), a 12-dimensional observation state vector (reflecting the current positions of robot joints), and three video observations—videos captured by a top RealSense color camera, a right wrist camera, and a left wrist camera (all with a resolution of 480x640, 3 channels, AV1 encoding). Additionally, the dataset includes metadata such as timestamps, frame indices, episode indices, and task indices. It is suitable for robot control, imitation learning, or reinforcement learning tasks, particularly for dual-arm robot manipulation scenarios. Data is stored in parquet file format, videos in mp4 format, with a total data size of approximately 300MB (100MB for data files and 200MB for video files).
