Agriculture — Solution Blueprint

Status: Experimental (scaffold) · Timeline: Later · Path: examples/solutions/agriculture/

Official Solution Blueprint for autonomous field robots, precision agriculture, and crop monitoring — composed from existing platform capabilities.

Full roadmap entry: ROADMAP.md § Agriculture

Purpose

Deploy and operate autonomous tractors, sprayers, drones, and sensor networks with offline-capable connectivity, geofenced safety, and seasonal trace replay.

Platform pillars used

Pillar	Capabilities
Device & Fleet	Device tree, GPS geofencing, cellular/LoRa failover, OTA
Verification	Readiness (weather, connectivity), assurance (crop anomaly)
Packages & Ecosystem	`spanda-gps`, `spanda-cellular`, `spanda-lora`, `spanda-opencv`
Operations	Fleet map, readiness trends, telemetry store

Reference architecture (planned)

Field Robot (.sd)
├── GPS + IMU (spanda-gps)
├── Vision row detection (spanda-opencv)
├── Cellular / LoRa uplink (spanda-cellular, spanda-lora)
├── Geofence safety (language safety zones)
├── Readiness gates (weather, calibration, connectivity)
└── Return-to-base recovery on link loss

Device tree (planned)

Node	Role
`tractor`	Primary autonomous platform
`implement`	Sprayer, seeder attachment
`drone`	Aerial crop survey
`base_station`	Edge gateway, LoRa concentrator

Packages & providers

Package	Role
`spanda-gps`	WGS84 positioning, geofences
`spanda-cellular`	LTE failover
`spanda-lora`	Low-power field mesh
`spanda-opencv`	Row/crop vision
`spanda-prognostics`	Equipment degradation
