When we first started building a data platform for robotics, we weren’t thinking about YouTube. Robotics teams wanted to be able to upload their LeRobot datasets, search across demonstrations, inspect synchronized camera feeds and robot states, and export curated episodes for training. That sounded like a fairly specialized problem in robotics. So we built Pareto. Once we got into the infrastructure work, the requirements started to feel familiar. We needed to reliably upload large media files,...
