HERON High Level Planner

High level planner (HLP) for the HERON project. This planner interfaces with the robot (UGV). the vision components (ICCS), and a Kafka server to recieve missions, plan, send commands for road maintanence tasks.

The HLP uses behaviour trees (BTs) to sequence through the mission.

Packages

• heron_planner: Main HLP packages with behaviour
• heron_ui: RViz panel with buttons to send service calls to HLP.
• heron_utils: Utilities for running tree, visulising tree, transforms.
• dummy_interface: Python utilities commonly used within moma projects.
