Residual Skill Policies: Learning an Adaptable Skill-based Action Space for Reinforcement Learning for Robotics

1 code implementation4 Nov 2022 Krishan Rana, Ming Xu, Brendan Tidd, Michael Milford, Niko Sünderhauf

Furthermore, the downstream RL agent is limited to learning structurally similar tasks to those used to construct the skill space.

Passing Through Narrow Gaps with Deep Reinforcement Learning

no code implementations6 Mar 2021 Brendan Tidd, Akansel Cosgun, Jurgen Leitner, Nicolas Hudson

While we show the feasibility of our approach in simulation, the difference in performance between simulated and real world scenarios highlight the difficulty of direct sim-to-real transfer for deep reinforcement learning policies.

Learning Setup Policies: Reliable Transition Between Locomotion Behaviours

no code implementations23 Jan 2021 Brendan Tidd, Nicolas Hudson, Akansel Cosgun, Jurgen Leitner

Dynamic platforms that operate over many unique terrain conditions typically require many behaviours.

Learning When to Switch: Composing Controllers to Traverse a Sequence of Terrain Artifacts

no code implementations1 Nov 2020 Brendan Tidd, Nicolas Hudson, Akansel Cosgun, Jurgen Leitner

Legged robots often use separate control policiesthat are highly engineered for traversing difficult terrain suchas stairs, gaps, and steps, where switching between policies isonly possible when the robot is in a region that is commonto adjacent controllers.

Guided Curriculum Learning for Walking Over Complex Terrain

no code implementations8 Oct 2020 Brendan Tidd, Nicolas Hudson, Akansel Cosgun

Reliable bipedal walking over complex terrain is a challenging problem, using a curriculum can help learning.
