- What happened
- NVIDIA Isaac ROS 5.0 enables zero-copy GPU data exchange between ROS 2 nodes using rosidl::Buffer and CUDA backend, eliminating host copies at node boundaries.
- Why it matters
- Robotics engineers optimizing GPU-accelerated perception pipelines on Jetson or data center platforms need to eliminate CPU serialization bottlenecks between CUDA workloads.
- Watch out
- Zero-copy optimization requires publisher and subscriber on same host, CUDA device, Linux user, and supported RMW implementation; CPU fallback activates automatically when conditions unmet.

The patterns behind this
Each one covers how the technique works, when it earns its cost, and where it breaks.
