Multi-Phase Multi-Objective Dexterous Manipulation with Adaptive Hierarchical Curriculum

no code implementations26 May 2022 Lingfeng Tao, Jiucai Zhang, Xiaoli Zhang

Dexterous manipulation tasks usually have multiple objectives, and the priorities of these objectives may vary at different phases of a manipulation task.

Physics-Guided Hierarchical Reward Mechanism for Learning-Based Robotic Grasping

no code implementations26 May 2022 Yunsik Jung, Lingfeng Tao, Michael Bowman, Jiucai Zhang, Xiaoli Zhang

In this work, we develop a novel Physics-Guided Deep Reinforcement Learning with a Hierarchical Reward Mechanism to improve learning efficiency and generalizability for learning-based autonomous grasping.

Learn and Transfer Knowledge of Preferred Assistance Strategies in Semi-autonomous Telemanipulation

no code implementations7 Mar 2020 Lingfeng Tao, Michael Bowman, Xu Zhou, Jiucai Zhang, Xiaoli Zhang

Enabling robots to provide effective assistance yet still accommodating the operator's commands for telemanipulation of an object is very challenging because robot's assistive action is not always intuitive for human operators and human behaviors and preferences are sometimes ambiguous for the robot to interpret.

Learn Task First or Learn Human Partner First: A Hierarchical Task Decomposition Method for Human-Robot Cooperation

no code implementations1 Mar 2020 Lingfeng Tao, Michael Bowman, Jiucai Zhang, Xiaoli Zhang

Applying Deep Reinforcement Learning (DRL) to Human-Robot Cooperation (HRC) in dynamic control problems is promising yet challenging as the robot needs to learn the dynamics of the controlled system and dynamics of the human partner.
