System Narrative
The systemigram reads your model as a story. Nodes become noun phrases, interfaces become verb phrases. The diagonal mainstay tells the central purpose; branches show supporting flows.
The Mainstay
The primary narrative arc reads from top-left to bottom-right: Solar Array generates power, which Power Distribution delivers to the Nav Computer, which commands Hub Motors to traverse terrain. This is the core energy-to-motion transformation chain — the reason the rover exists.
Perception Branch
Three sensor inputs converge on the Nav Computer: LiDAR scans terrain for obstacles, GPS localizes position globally, and IMU stabilizes attitude estimation. This sensor fusion enables the decision engine to plan paths through unknown environments.
Communication Branch
The Nav Computer reports status to the Comms Processor, which streams telemetry to the Ground Station (external). This closes the human-in-the-loop: operators can monitor and override the autonomous system remotely.
Cross-Connections
Thermal Management appears as a support system — it cools the Battery Pack but doesn't participate in the primary transformation chain. Power Distribution also feeds Hub Motors directly (dashed line), showing that the energy bus crosses multiple narrative branches.
