xlerobot_generalist_v2
收藏资源简介:
该数据集是一个用于机器人控制的数据集,使用LeRobot工具创建。它包含xlerobot类型双臂机器人的传感器数据和视频观察,适用于训练和评估机器人学习模型。数据集包括以下特征:观察状态(18维浮点数组,表示左右臂的关节位置、头部位置、速度等)、动作(与观察状态相同维度的控制命令)、来自头部、左腕和右腕摄像头的视频观察(分辨率360x640,3通道RGB,30fps,AV1编码),以及时间戳、帧索引、episode索引、任务索引等元数据。数据集总共有236个episodes、248,425帧、3个任务,以parquet文件格式存储,总数据大小约为300MB(数据100MB,视频200MB)。数据按chunk组织,用于机器学习中的机器人任务。
This dataset is designed for robot control and was created using the LeRobot tool. It includes sensor data and video observations from an xlerobot-type dual-arm robot, suitable for training and evaluating robot learning models. The dataset features: observation states (an 18-dimensional floating-point array representing joint positions of the left and right arms, head position, velocity, etc.), actions (control commands with the same dimensions as the observation states), video observations from head, left wrist, and right wrist cameras (resolution 360x640, 3-channel RGB, 30fps, AV1 encoding), along with metadata such as timestamps, frame indices, episode indices, and task indices. The dataset contains a total of 236 episodes, 248,425 frames, and 3 tasks, stored in the parquet file format, with a total data size of approximately 300MB (100MB for data and 200MB for videos). The data is organized into chunks for use in machine learning-based robot tasks.
