Proposal for auto-generated Nodes in Behavior Trees

[moccajoghurt]

Problem Statement:
Currently, each node requires a C++ code implementation for its execution.

Objective:
Introduce a functionality that allows nodes to be generated exclusively via XML, making the Groot2 editor the sole tool required for Behavior Trees.

Background:

• We need a large number of Behavior Trees.
• It should be possible for individuals without C++ knowledge to create Behavior Trees.
• Groot2 stands out as an efficient editor for constructing Behavior Trees.

Proposed Solution:

• Integrate an "auto-generated" option into BT::BehaviorTreeFactory that can be activated when importing an XML-BehaviorTree.
• When the "auto-generated" option for Conditions & Actions is activated, the existence of a Service-/Action-Node in ROS is presupposed, which can be called upon.
• The Service-/Action-Node in ROS sends feedback (Success, Failed, Running), which is relayed by the "auto-generated" BT-Node.

Advantages:

• Complete separation between robot interactions and Behavior Tree execution.
• Robots only need to provide an interaction interface via ROS.
• Logic-related tasks can be implemented independently.
• This approach promotes the Separation of Concerns and can significantly enhance the efficiency of our work.

Feedback Request:
Do you find this to be a good idea? Would there be interest if I were to work on this feature?

After delving deeper into the topic, my proposal appears to be unnecessary.
