Center node: "dynamic manipulation of flexible objects with torque sequence using a deep neural network"
  Abstract: For dynamic manipulation of flexible objects, we propose an acquisition method of a flexible object motion equation model using a deep neural network and a control method to realize a target state by calculating an optimized time-series joint torque command. By using the proposed method, any physics model of a target object is not needed, and the object can be controlled as intended. We applied this method to manipulations of a rigid object, a flexible object with and without environmental contact, and a cloth, and verified its effectiveness.

Connected through hyperedge HE-1 (induced by source paper "dynamic cloth manipulation with deep reinforcement learning"):
