ROSO: Improving Robotic Policy Inference via Synthetic Observations

no code implementations28 Nov 2023 Yusuke Miyashita, Dimitris Gahtidis, Colin La, Jeremy Rabinowicz, Jurgen Leitner

In this paper, we propose the use of generative artificial intelligence (AI) to improve zero-shot performance of a pre-trained policy by altering observations during inference.

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.
