<p>Robotics datasets don't share a layout. One is LeRobot v2, the next is LeRobot v3 with a dozen sub-datasets inside, another is RLDS shards, an MCAP recording, an HDF5 file or a Zarr store. Looking inside one usually means downloading it and writing a viewer for that one layout.</p><p>RoboPeek reads the layout for you. Paste a Hugging Face link to a public dataset, or any folder or file inside one. It works out what it is and opens the whole dataset in your browser.</p><h3>What it opens</h3><ul><li><p>LeRobot v2 and v3, RLDS (TFRecord), MCAP (ROS 1, ROS 2, protobuf, JSON), HDF5, Zarr, and folders of camera videos</p></li><li><p>Repos that hold several datasets: each sub-dataset is listed and opens on its own</p></li><li><p>Datasets the Hub's own viewer can't preview, like the HDF5, Zarr and MCAP samples on the site</p></li></ul><h3>What you get for a dataset</h3><ul><li><p>Every episode in one list, with its length, task instruction and filters</p></li><li><p>All cameras in sync, each one switchable</p></li><li><p>Every recorded signal (actions, joint state, forces) charted frame by frame, with the task instruction on the same timeline</p></li><li><p>Stats on episode lengths, and Insights that find length outliers across all episodes</p></li><li><p>Flag episodes from the player or the lists, then export the flagged set as a LeRobot command</p></li><li><p>A link for every dataset and episode, so a colleague opens the same view</p></li></ul><h3>How it reads</h3><ul><li><p>Files stream straight from Hugging Face, and only the parts you look at are read</p></li><li><p>Nothing to install. Local TFRecord and MCAP files are read in the browser, not uploaded</p></li></ul><h3>Built to embed</h3><p>The RLDS and MCAP readers and a React viewer are on npm under MIT. Put the viewer in a dataset catalogue, a labelling tool or a research dashboard, or use a reader on its own. datasets.bot is the first app built on it.</p><p>Limits today: public datasets only, and a few layouts still don't open fully (for example, camera frames stored inside Parquet files show joint data only). If yours doesn't open, open an issue on GitHub.</p><p>Built and maintained by VideoDB.</p>
