ROSDeck

ROS2 Mobile turns your phone into a ground control station for ROS 2 robots. Connect over Wi-Fi and drive, monitor, and visualize — no laptop needed. FEATURES • Joystick — drive your robot with a virtual thumbstick. Publishes Twist or TwistStamped to /cmd_vel with configurable velocity limits and haptic feedback. • Camera — view live camera feeds via MJPEG (web_video_server) or directly over WebSocket (CompressedImage). Rendered with hardware-accelerated Skia. • Map — visualize occupancy grids, laser scans, robot position, and costmaps. Works with or without a map — scan-only mode shows lidar data centered on the robot. • Diagnostics — monitor battery, motor status, and system health from diagnostic_msgs. • Topic Viewer — inspect any ROS 2 topic as raw JSON with adjustable text size. • TF Tree — browse the transform tree in real time. • Configurable Layouts — split, resize, and arrange widgets however you want. Save layouts per robot. Five presets included: Drive, Drive + Camera, Camera Only, Nav, and Dashboard. CONNECTIVITY Supports both Foxglove Bridge (recommended, binary protocol) and Rosbridge (JSON protocol). Auto-detects available topics and suggests the best layout for your robot. DEMO MODE Try the app without a robot — demo mode simulates a connection so you can explore all widgets and layouts. PRIVACY No accounts, no analytics, no cloud. All data stays on your device. Communication is local Wi-Fi only. REQUIREMENTS • A ROS 2 robot on the same Wi-Fi network • Foxglove Bridge or Rosbridge running on the robot • Optional: web_video_server for MJPEG camera streams
