Learning Robot Manipulation from Cross-Morphology Demonstration

1 code implementation7 Apr 2023 Gautam Salhotra, I-Chun Arthur Liu, Gaurav Sukhatme

Some Learning from Demonstrations (LfD) methods handle small mismatches in the action spaces of the teacher and student.

Imitation Learning Robot Manipulation

Learning Deformable Object Manipulation from Expert Demonstrations

1 code implementation20 Jul 2022 Gautam Salhotra, I-Chun Arthur Liu, Marcus Dominguez-Kuhne, Gaurav S. Sukhatme

We test DMfD on a set of representative manipulation tasks for a 1-dimensional rope and a 2-dimensional cloth from the SoftGym suite of tasks, each with state and image observations.

Adaptive Sampling using POMDPs with Domain-Specific Considerations

1 code implementation23 Sep 2021 Gautam Salhotra, Christopher E. Denniston, David A. Caron, Gaurav S. Sukhatme

We find that by using knowledge of the number of rollouts allocated, the agent can more effectively choose actions to explore.

PLGRIM: Hierarchical Value Learning for Large-scale Exploration in Unknown Environments

no code implementations10 Feb 2021 Sung-Kyun Kim, Amanda Bouman, Gautam Salhotra, David D. Fan, Kyohei Otsu, Joel Burdick, Ali-akbar Agha-mohammadi

In order for an autonomous robot to efficiently explore an unknown environment, it must account for uncertainty in sensor measurements, hazard assessment, localization, and motion execution.

Motion Planner Augmented Reinforcement Learning for Robot Manipulation in Obstructed Environments

no code implementations22 Oct 2020 Jun Yamada, Youngwoon Lee, Gautam Salhotra, Karl Pertsch, Max Pflueger, Gaurav S. Sukhatme, Joseph J. Lim, Peter Englert

In contrast, motion planners use explicit models of the agent and environment to plan collision-free paths to faraway goals, but suffer from inaccurate models in tasks that require contacts with the environment.
