Abstract: Candidate grasping models of a deformable object are applied to generate a simulation of a response of the deformable object to the grasping model. From the simulation, grasp performance metrics for stress, deformation controllability, and instability of the response to the grasping model are obtained, and the grasp performance metrics are correlated with robotic grasp features.

Abstract: Mechanisms to enhance robotic agent performance utilizing dynamically curated demonstration trajectories to augment agent training, whereby additional demonstrations are dynamically curated or generated and added to the demonstration training set for the robot based on task difficulty and initial state complexity, thereby utilizing a greater number of training demonstrations for unsolved or poorly performing tasks and challenging initial states.
