The Task Constructor framework provides a flexible and transparent way to define and plan actions that consist of multiple interdependent subtasks. It draws on the planning capabilities of MoveIt to solve individual subproblems in black-box planning stages. A common interface, based on MoveIt's PlanningScene is used to pass solution hypotheses between stages. The framework enables the hierarchical organization of basic stages using containers, allowing for sequential as well as parallel compositions.

We provide a tutorial for a pick-and-place pipeline without bells & whistles as part of the MoveIt tutorials.
Feedback, reports and contributions are very welcome.
The current roadmap is to replace MoveIt's old pick&place pipeline and provide a transparent mechanism to enable and debug complex motion sequences.
Further planned features include
- Entwined planning and execution for early execution, monitoring and code hooks
- Subsolution blending
- Parallel planning
- Iterative solution improvement
Ideas and requests for other interesting/useful features are welcome.
