Visualizing and Debugging Robot Learning Data with Voxel51 and Hugging Face’s LeRobot

Robot learning data doesn't look like the data that trains most vision-language models. It's temporal, low-dimensional in the parts that matter most, embodiment-specific, and expensive to collect, and increasingly, it's shipped in Hugging Face's Le Robot format. But packaging robot data consistently isn't the same as being able to see it: episodes hide broken metadata, silently dropped sensor modalities, and mismatched schemas between robots that look identical on paper. This workshop is a hands-on tour of what actually breaks when you load real Le Robot datasets, and how Voxel51's native Le Robot support in Voxel51 catches it.
