MCAP
MCAP is an open-source container file format for heterogeneous, timestamped robotics log data, developed by Foxglove and adopted as the default storage backend for ROS 2 rosbag2. It stores serialized messages from multiple channels with self-contained schemas, supports chunked compression and indexed random access, and is serialization-agnostic, handling ROS messages, Protobuf, and JSON in a single append-friendly file suitable for high-rate logging.
Why it matters for physical AI
Robot learning runs on logged experience; a fast, self-describing, tool-friendly log format streamlines the pipeline from fleet recordings to visualization, curation, and training datasets across heterogeneous systems.
