About:
LCM (Lightweight Communications and Marshalling) is a suite of libraries and tools for message passing and data marshalling. It provides a high-bandwidth, low-latency protocol for real-time systems, enabling efficient data exchange between processes. Its main value is simplifying complex distributed applications by handling the transport layer automatically.
Key Features:
  • Publish/subscribe messaging architecture
  • Language bindings for C, C++, Java, Python, and C#
  • High-performance, low-latency UDP-based transport
  • Self-describing binary message serialization
Use Cases:
  • Real-time robotics control systems
  • Distributed sensor data aggregation
  • High-performance inter-process communication (IPC)
Alternatives:
  • ZeroMQ – More flexible transport layers but LCM is optimized for high-throughput, real-time data streams.
  • ROS – Full robotics framework; LCM is a lighter, standalone messaging library.
