This page adds depth beyond the root README — not a second copy of the same prose.
Hardware is the body.
Sensors are the senses.
AI models are the mind.
Actuators are the muscles.
Spanda is the intelligent pulse that transforms perception, intent, and safety into action.
Spanda (Pronounced SPUN-duh (/ˈspʌndə/)) is a Sanskrit term meaning the divine pulse — the creative vibration of consciousness and energy that manifests as expansion and contraction in all entities, bridging stillness and movement within consciousness; and the first stir of awareness that creates and sustains the universe.
In software terms: the coordination layer that turns perception into verified, safe action.
The body metaphor describes what each part is on one robot. At fleet scale and during offline operation, Spanda adds a nervous-system hierarchy for where decisions are allowed to happen:
| Layer | Role | In Spanda |
|---|---|---|
| Reflex | Instant safety — never waits on cloud or model output | safety { }, kill switch, trust rejection |
| Spinal cord | Bounded local autonomy when the link is slow or gone | local_decision_authority, decision_tree, signed offline_policy |
| Brain | Strategy, policy, assurance, human approval — not every motor tick | Control Center, fleet coordination, central approval gates |
AI models are the mind — they propose plans and perceive the world. They are not the control-center brain: proposals still pass through safety, trust, and policy before they reach actuators, and urgent reflexes never wait on a model.
Spanda is the pulse that routes intent across this hierarchy, enforces boundaries at each layer, and keeps every decision auditable and replayable.
