## New files
- saltybot_social_msgs/msg/VoiceCommand.msg
intent + entities[] + confidence + confirmation_token + requires_confirmation
- saltybot_social/voice_command_parser.py
Pure-Python regex NLU, zero ROS2/ML deps, < 1 ms/call
30+ named intents across nav.*, social.*, system.*, config.*, confirm.*
Entity extraction: location, name, mode, level, route name
Dangerous-command flag: system.shutdown, system.restart, social.forget_me
- saltybot_social/voice_command_node.py
Subscribes /social/speech/transcript, publishes /social/voice_command
Confirmation flow with UUID token + 10 s timeout
Below-threshold → intent=fallback → LLM conversation engine
- saltybot_social/test/test_voice_command_parser.py
191 unit tests (all pass), no ROS2 runtime required
- saltybot_social/config/voice_command_params.yaml
- saltybot_social/launch/voice_command.launch.py
## Intent taxonomy
nav: go_to, go_home, follow_me, stop, wait, come_here, patrol,
set_mode (shadow/lead/side/orbit/loose/tight),
teach_route, stop_teaching, replay_route
social: remember_me, forget_me [CONFIRM], whats_my_name, tell_joke
system: battery_status, map_status, shutdown [CONFIRM], restart [CONFIRM],
volume_up, volume_down, volume_set
config: personality, sass_level, follow_mode
## Updated
- saltybot_social_msgs/CMakeLists.txt: register VoiceCommand.msg
- saltybot_social/setup.py: add voice_command_node entry point

Jetson Nano — AI/SLAM Platform Setup
Self-balancing robot: Jetson Nano dev environment for ROS2 Humble + SLAM stack.
Stack
| Component | Version / Part |
|---|---|
| Platform | Jetson Nano 4GB |
| JetPack | 4.6 (L4T R32.6.1, CUDA 10.2) |
| ROS2 | Humble Hawksbill |
| DDS | CycloneDDS |
| SLAM | slam_toolbox |
| Nav | Nav2 |
| Depth camera | Intel RealSense D435i |
| LiDAR | RPLIDAR A1M8 |
| MCU bridge | STM32F722 (USB CDC @ 921600) |
Quick Start
# 1. Host setup (once, on fresh JetPack 4.6)
sudo bash scripts/setup-jetson.sh
# 2. Build Docker image
bash scripts/build-and-run.sh build
# 3. Start full stack
bash scripts/build-and-run.sh up
# 4. Open ROS2 shell
bash scripts/build-and-run.sh shell

Power Budget (Summary)
| Scenario | Total |
|---|---|
| Idle | 2.9W |
| Nominal (SLAM active) | ~10.2W |
| Peak | 15.4W |
Target: 10W (MAXN nvpmodel). Use RPLIDAR standby + 640p D435i for compliance.
See docs/power-budget.md for full analysis.
