Prerequisites · 사전 준비

Node.js 20+ and Python 3.10+. Requires @cell-coding/cli on PATH (or monorepo clone):

npm install -g @cell-coding/cli
pip install cell-coding-bridge   # PyPI · after v0.1.0 release

Monorepo dev:

cd typescript && npm install

Cloud runtime · cloud runtime

runtime-docker organ HTTP ingress (POST /v1/signals):

# motion-alarm organ (:8087) — Physical AI default
docker compose -f runtime-docker/docker-compose.yml up -d motion-alarm redis
python demo_cloud.py

# auth-organ (:8081)
python demo_cloud.py --url http://127.0.0.1:8081

# divide gateway (:8086, profile divide-scale)
python demo_cloud.py --url http://127.0.0.1:8086

Environment · 환경 변수:

Variable	Default	Description
CELL_CLOUD_URL	http://127.0.0.1:8087	demo_cloud.py base URL
CELL_MOTION_ALARM_URL	http://127.0.0.1:8087	motion-alarm organ
CELL_NODE	node	Node binary for cell run
CELL_CLI	cell	Override cell binary path
CELL_FORCE_GLOBAL_CLI	—	Use global cell even in monorepo

PyPI package · PyPI 패키지

Architecture · 구조

Python sensor (simulate_motion)
    → cell run --json (TypeScript runtime)
    → trace JSON
    → Python actuator (extract_alarm_actions)

Cloud path · cloud 경로:

simulate_motion → POST /v1/signals → cloud-serve (AlarmOrgan) → trace → extract_alarm_actions

Future: GPIO alarm hardware; see ROBOTICS.md for IMU/Joint/Vision/Twist adapters.

Optional extras · 선택 의존성:

pip install cell-coding-bridge[ros2]     # ROS2 live (requires sourced ROS env)
