robokudo.idioms

Common behavior patterns for RoboKudo pipelines.

This module provides reusable behavior patterns that are commonly used in RoboKudo pipelines. These patterns encapsulate standard combinations of annotators and behaviors that are frequently needed together.

The module provides:

  • Standard initialization sequences for pipelines

  • Common error handling patterns

  • Reusable behavior combinations

Functions

non_query_pipeline_init(→ py_trees.behaviour.Behaviour)

Same as pipeline_init(), but without waiting for the query-related actions to complete.

pipeline_init(→ py_trees.behaviour.Behaviour)

This method returns a Behaviour/Composite node which hosts different nodes to reset and prepare internal

Module Contents

robokudo.idioms.non_query_pipeline_init() → py_trees.behaviour.Behaviour

Same as pipeline_init(), but without waiting for the query-related actions to complete. This is the behavior which was used before Dec’25 in RK by default. :return:

robokudo.idioms.pipeline_init() → py_trees.behaviour.Behaviour

This method returns a Behaviour/Composite node which hosts different nodes to reset and prepare internal datastructures properly before the next iteration can start. It will reset the visualization outputs (Annotator Outputs), waits until all pending operations on the query server (if present) are done (abort goal operations, send goal results, etc.). Finally, it will clear any previous exceptions present in the error variable.

Returns:

A sequence behavior containing initialization steps

Return type:

py_trees.behaviour.Behaviour
