收藏资源简介:
该数据集由LeRobot工具创建,专为机器人学任务设计。数据集使用Unitree G1 Dex3人形机器人采集,包含100个训练片段,总计31803帧数据,以30fps录制。数据以parquet格式存储(总大小100MB),并包含配套视频文件(总大小500MB)。特征包括:28维浮点型状态观测向量(对应机器人左右肩、肘、腕及手指关节角度)、28维动作向量(结构同状态),以及四个摄像头视频流观测(左肩高、右肩高、左腕、右腕,分辨率均为480x640,3通道RGB,AV1编码)。此外,数据包含时间戳、帧索引、片段索引等辅助字段。数据集仅提供训练集划分,适用于机器人模仿学习或控制算法开发。
This dataset was created by the LeRobot tool and is specifically designed for robotics tasks. It was collected using a Unitree G1 Dex3 humanoid robot, containing 100 training episodes with a total of 31,803 frames recorded at 30fps. The data is stored in parquet format (total size 100MB) and includes accompanying video files (total size 500MB). Features include: a 28-dimensional floating-point state observation vector (corresponding to the robots left and right shoulder, elbow, wrist, and finger joint angles), a 28-dimensional action vector (with the same structure as the state), and observations from four camera video streams (left shoulder high, right shoulder high, left wrist, right wrist, all with a resolution of 480x640, 3-channel RGB, AV1 encoding). Additionally, the data includes auxiliary fields such as timestamps, frame indices, and episode indices. The dataset only provides a training set split and is suitable for robot imitation learning or control algorithm development.
