NVIDIA updates Isaac ROS 5.0 to use rosidl::Buffer CUDA backend for zero-copy GPU transport
NVIDIA contributed a CUDA buffer backend to ROS 2 Lyrical and updated all nodes in NVIDIA Isaac ROS 5.0 to use rosidl::Buffer, enabling zero-copy GPU-resident message transport when runtime conditions allow. The post demonstrates an AI coding agent (migrate-node-to-rosidl-buffer skill) migrating a TensorRT-based Depth Anything 3 node, and verifies the optimized path with NVIDIA Nsight Systems and runtime checks that report backend_type == "cuda".
