# Modes & Lifecycle

How OM1 organizes behavior into modes and manages their lifecycle.

OM1 structures robot behavior into **modes** — distinct operational states such as social interaction, exploration, patrol, or autonomous navigation — and governs how the system moves between them.

This section covers:

* [**Modes**](/build/modes_lifecycle/modes.md) — what modes are and how each one shapes perception, input handling, and task priorities.
* [**Mode Selection**](/build/modes_lifecycle/mode_selection.md) — the different ways to switch modes: context-aware, time-based, input-triggered, or manual.
* [**Transition Rules**](/build/modes_lifecycle/transition_rules.md) — how and when the robot moves between modes, defined as prioritized rule objects.
* [**Lifecycle**](/build/modes_lifecycle/lifecycle.md) — the activation-to-termination boundaries of a mode, ensuring predictable, safe transitions.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openmind.com/build/modes_lifecycle.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
