Platform upgrade: Jetson Nano 4GB → Orin Nano Super 8GB (March 1, 2026) All Nano-era constraints removed — power/rate/resolution limits obsolete. Dockerfile: l4t-jetpack:r36.2.0 (JetPack 6 / Ubuntu 22.04 / CUDA 12.x), ROS2 Humble via native apt, added ros-humble-rtabmap-ros, ros-humble-v4l2-camera for future IMX219 CSI (Phase 2c) New: slam_rtabmap.launch.py — Orin primary SLAM entry point RTAB-Map with subscribe_scan (RPLIDAR) + subscribe_rgbd (D435i) Replaces slam_toolbox as docker-compose default New: config/rtabmap_params.yaml — Orin-optimized DetectionRate 10Hz, MaxFeatures 1000, Grid/3D true, TimeThr 0 (no limit), Mem/STMSize 0 (unlimited) Updated: config/realsense_d435i.yaml — 848x480x30, pointcloud enabled Updated: config/slam_toolbox_params.yaml — 10Hz rate, 1s map interval Updated: SLAM-SETUP-PLAN.md — full rewrite for Orin: arch diagram, Phase 2c IMX219 plan (4x 160° CSI surround), 25W power budget docker-compose.yml: image tag jetson-orin, default → slam_rtabmap.launch.py Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
