- vector-control
- description
- Control a Vector robot via Wirepod’s local HTTP API on the same network. Use when you need to move Vector, tilt head/lift, speak text, capture camera frames, or run patrol/explore routines from the Pi/Wirepod host. Includes a CLI helper script and endpoint reference.
Vector Control
Overview
Control Vector through Wirepod’s /api-sdk/* endpoints and the camera stream at /cam-stream. Use this skill for movement, speech, camera snapshots, patrols, and exploration from the Pi.
Quick start (CLI)
Use the bundled script:
python3 skills/vector-control/scripts/vector_control.py --serial <ESN> assume
python3 skills/vector-control/scripts/vector_control.py --serial <ESN> say --text "Hello Dom"
python3 skills/vector-control/scripts/vector_control.py --serial <ESN> move --lw 160 --rw 160 --time 1.5
python3 skills/vector-control/scripts/vector_control.py --serial <ESN> snapshot --out /tmp/vector.mjpgFind ESN/serial
If you don’t have it, read:
/etc/wire-pod/wire-pod/jdocs/botSdkInfo.json
Tasks
1) Assume / Release control
Always assume before movement, and release if the bot tips or a human needs manual control.
python3 .../vector_control.py --serial <ESN> assume
python3 .../vector_control.py --serial <ESN> release2) Movement
movesends wheel speeds (0–200 typical). Use short timed moves.
python3 .../vector_control.py --serial <ESN> move --lw 120 --rw 120 --time 1.03) Head / Lift
python3 .../vector_control.py --serial <ESN> head --speed -2 --time 1.0
python3 .../vector_control.py --serial <ESN> lift --speed 2 --time 1.04) Speech
Speech can be interrupted by motion/camera. If it fails, pause after speaking before moving.
python3 .../vector_control.py --serial <ESN> say --text "Sneaking forward"
# wait 1–2s, then move5) Camera snapshot
/cam-stream returns MJPG. Save it and convert to JPEG if needed (ffmpeg).
python3 .../vector_control.py --serial <ESN> snapshot --out /tmp/vector.mjpg
ffmpeg -y -loglevel error -i /tmp/vector.mjpg -frames:v 1 /tmp/vector.jpg6) Play Audio (MP3/WAV)
Streams an audio file through Vector's speaker. Automatically converts to the required format (8kHz mono WAV).
python3 .../vector_control.py --serial <ESN> play --file /path/to/music.mp37) Patrol (deterministic sweep)
python3 .../vector_control.py --serial <ESN> patrol --steps 6 --speed 140 --step-time 1.2 --turn-time 0.8 --speak --phrase "Patrolling"8) Explore (randomized wander)
python3 .../vector_control.py --serial <ESN> explore --steps 8 --speak --phrase "Exploring"References
