NettetThe proposed Feudal Graph Reinforcement Learning (FGRL) framework, high-level decisions at the top level of the hierarchy are propagated through a layered graph representing a hierarchy of policies, where lower layers mimic the morphology of the physical system and upper layers can capture more abstract sub-modules. We focus … NettetLearning Modular Robot Control Policies . Modular robots can be rearranged into a new design, perhaps each day, to handle a wide variety of tasks by forming a customized robot for each new task. However, reconfiguring just the mechanism is not sufficient: each design also requires its own unique control policy. Nettet25. feb. 2024 · Compared to traditional data-driven learning methods, recently developed deep reinforcement learning (DRL) approaches can be employed to train robot agents to obtain control policies with appealing performance. However, learning control policies for real-world robots through DRL is costly and cumbersome. lota meaning in english

"Nettet27. aug. 2024 · In this study, the control problem is addressed by in-troducing a hierarchical reinforcement learning method that can learn the end-to-end control policy of a multi-DOF manipula-tor without any constraints on the state-action space. The proposed method learns hierarchical policy using two off-policy methods. " - Learning modular robot control policies

NettetRobot learning with such modular control systems, however, is still in its infancy. Reinforcement learning has recently begun to formulate a principled approach to this problem (Sutton, Precup, & Singh, 1999). Another route of investigating modular robot learning comes from formulating sub-policies as nonlinear dynamical systems Nettetpolicy was conditioned on both the workspace target and the robot design. Bhardwaj, Choudhury, and Scherer (2024) learned a search heuristic for a best-ﬁrst search, used as a path planner in a grid world; we also learn a best-ﬁrst search heuristic, but in the context of design rather than planning. 2.2 Deep Q-learning for Modular Robot Design
