Extending Task and Motion Planning with Feasibility Prediction: Towards Multi-Robot Manipulation Planning of Realistic Objects
Résumé
The hybrid discrete/continuous nature of task and
motion planning (TAMP) results often in a combinatorial
explosion. This challenge is even more pronounced in multi-
robot TAMP problems due to the increase in dimensionality of
the action space. Previous works use action feasibility prediction
as a heuristic to accelerate TAMP. However, these methods are
limited to box-shaped objects and specific single or dual robot
settings. In this paper, we expand on our previous work on
action and grasp feasibility prediction [1] by extending its use
to complex-shaped objects and multi-robot systems. Also, we
propose a feasibility-enabled multi-robot TAMP algorithm ca-
pable of tackling complex multi-robot manipulation problems.
We demonstrate the performance of our method compared to a
non feasibility-informed baseline, and show its ability to handle
TAMP problems requiring the collaboration of multiple robots.
