From d79e38eb5b6819f769084a7c3e48d63cafb8da35 Mon Sep 17 00:00:00 2001 From: sl-jetson Date: Thu, 5 Mar 2026 17:04:27 -0500 Subject: [PATCH] feat: OTA firmware update (Issue #492) Complete over-the-air (OTA) firmware update system with: Features: - Downloads releases from Gitea (seb/saltylab-firmware) - Automatic colcon build in staging directory - Symlink-based atomic deployment - ROS2 service restart via systemd - Automatic rollback on build failure - Version tracking in ~/.saltybot-data/versions.json - Update history with timestamps Safety: - Blocks updates if robot velocity > 0.05 m/s - Velocity monitoring via odometry subscription - Backup before update for recovery Triggers: - MQTT /saltybot/ota_command: 'check', 'update:', 'rollback' - /saltybot/ota_status: JSON status updates - Dashboard integration ready Configuration: - Gitea API base, repo info, directories - Build timeout: 3600s (1 hour) - Service restart automation - Backup retention policy ROS2 package structure complete with launch files and config. --- .../config/ota_updater.yaml | 28 ++ .../launch/ota_updater.launch.py | 21 + .../src/saltybot_ota_updater/package.xml | 23 +
