A Tour of Robotics Datasets: MCAP and LeRobot in Voxel51

Robotics data arrives in two very different shapes. MCAP files are continuous, lossless logs of everything a robot's sensors recorded, built for playback, SLAM, and sensor fusion. LeRobot datasets are synchronized episodes of camera, state, and action, built for training vision-language-action policies. In this talk, Harpreet takes a tour through real datasets in both formats inside Voxel51, showing what each one contains and what it leaves out. Along the way he covers how the two formats differ in structure and purpose, what breaks when you load real robot data, and how to inspect episodes, sensor streams, and metadata before training on them. Expect live dataset walkthroughs rather than slides. Harpreet Sahota is a hacker-in-residence and machine learning engineer with a passion for deep learning and generative AI.
