Overview
What it does: Robotheca's summary
- Visualises behaviour trees, with collapsible subtrees and zoom to fit the contents.
- Rewinds and resumes a timeline of tree states for debugging past behaviour.
- Shows blackboard data and an activity view, and can filter blackboard keys by selected behaviours.
- Discovers and switches between running py_trees instances via a namespace drop-down.
- Can be reconfigured to request blackboard introspection and more frequent updates.
- Built on the py_trees_js library, so it can be adapted to other tree implementations, middleware, or web use.
