Hello,

I have run through the tutorials for both SMACH and teer. I am wondering if anyone has implemented a ROS package based on behavior trees as used in some AI game software?

Thanks!
patrick

I have just discovered this package which has its own implementation of behavior trees.

I haven't tried yet, but It might be what you are looking for.

Recently did my own searching, and also came across https://github.com/almc/behavior_trees as an implementation from this paper: http://www.csc.kth.se/~almc/pdf/unifi...

I actually found a stable behavior tree implementation here: https://github.com/miccol/ROS-Behavio... . I first started first using the almc implementation, but the miccol one has the concept of "halt" that allows an action to be preempted.

I ended up writing my own Python implementation called pi_trees which includes ROS wrappers for actions, topics and services.

New package BehaviorTree.CPP is also available. Looks very promising. There is also video from ROSDevCon.

Thanks! I am currently using Py Trees which seems to be a very thorough implementation, well documented, and actively developed.
