We show that representing objects as signed-distance fields not only enables to learn and represent a variety of models with higher accuracy compared to point-cloud and occupancy measure representations, but also that SDF-based models are suitable for optimization-based planning.

Robotic manipulation planning is the problem of finding a sequence of robot configurations that involves interactions with objects in the scene, e. g., grasp, placement, tool-use, etc.

This is possible by encoding the objects of the scene in images as input to the neural network, instead of a fixed feature vector.
