SERIES / TECHNICAL NOTES
Inside Robotic Systems
A series on the stack behind modern robots — middleware, control, perception, simulation, and learning.
Inside ROS 2: Anatomy of a Robot Communication System
An under-the-hood tour of ROS 2's communication fabric, from DDS and core primitives to QoS, executors, and zero-copy paths for large model payloads.
Inside Robot Data Storage: MCAP, Zarr, and Multimodal Datasets at Scale
How production robot fleets store multimodal data: MCAP and Zarr layouts, sharding, featurization, and the dominant production patterns (plus academic alternatives) for datasets that stay queryable at scale.
Inside Robot Data Pipelines: Filtering, Autolabeling, and Training Processors
How robot datasets become training-ready: filtering and curation, dataset mixing and action-space harmonization, autolabeling and dataset enrichment, online training-time processors, and the distributed infrastructure that runs all of it at fleet scale.
