libero_goal_sawyer_additionalCams_failures
收藏资源简介:
该数据集是使用LeRobot创建的机器人数据集,专门针对Sawyer机器人。它包含460个episodes,总计60060帧,覆盖10个不同任务。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,帧率为20fps。数据集仅包含训练分割(所有episodes)。特征包括观察状态(如8维状态向量、6维末端执行器状态、7维关节状态、2维夹爪状态)、图像观察(前视图和侧视图,均为256x256 RGB视频)、7维动作向量,以及时间戳、帧索引、episode索引、索引和任务索引等元数据。数据集旨在支持机器人学习和控制任务,但主页和论文信息暂缺。
This is a robotics dataset developed using LeRobot, specifically optimized for the Sawyer robot. It consists of 460 episodes, with a total of 60060 frames, covering 10 distinct tasks. The data is stored in Parquet file format, where the non-video dataset files total 100 MB, and the video files amount to 200 MB, with a frame rate of 20 fps. The dataset only provides the training split, which includes all episodes. The features encompass observation states (including an 8-dimensional state vector, 6-dimensional end-effector state, 7-dimensional joint states, and 2-dimensional gripper state), visual observations (front and side views, both 256x256 RGB videos), a 7-dimensional action vector, as well as metadata such as timestamps, frame index, episode index, sample index, and task index. This dataset is designed to support robotics learning and control-related tasks, while its official homepage and associated academic paper information are currently unavailable.
