SaltyBot Android/Termux Phone Node (Issue #420)
Android phone node for SaltyBot via Termux. Provides camera, GPS, IMU sensors and local OpenClaw LLM inference.
Setup
On phone (Termux):
bash termux-bootstrap.sh
mkdir -p ~/saltybot_workspace/src
cd ~/saltybot_workspace && colcon build
Running
cd ~/saltybot_workspace && source install/setup.bash
ros2 launch saltybot_phone phone_bringup.py
Topics
| Topic | Type | Description |
|---|---|---|
/phone/camera/image_raw |
Image | Camera frames 320x240@15Hz |
/phone/gps |
NavSatFix | GPS location |
/phone/imu |
Imu | Accelerometer data |
/saltybot/speech_text |
String | Input from Jetson |
/saltybot/chat_response |
String | LLM output to Jetson |
Power Management
nohup bash ~/power-management.sh > ~/power-mgmt.log 2>&1 &
Reduces CPU activity on low battery (<25%) or critical battery (<15%).
Configuration
Edit config/phone.yaml to adjust frame rates and LLM parameters.
