Learning the correct robot trajectory in real-time from physical human interactions

DP Losey, MK O'Malley - ACM Transactions on Human-Robot …, 2019 - dl.acm.org
We present a learning and control strategy that enables robots to harness physical human
interventions to update their trajectory and goal during autonomous tasks. Within the state of …

Unified learning from demonstrations, corrections, and preferences during physical human-robot interaction

SA Mehta, DP Losey - ACM Transactions on Human-Robot Interaction, 2023 - dl.acm.org
Humans can leverage physical interaction to teach robot arms. This physical interaction
takes multiple forms depending on the task, the user, and what the robot has learned so far …

Learning from physical human corrections, one feature at a time

A Bajcsy, DP Losey, MK O'Malley… - Proceedings of the 2018 …, 2018 - dl.acm.org
We focus on learning robot objective functions from human guidance: specifically, from
physical corrections provided by the person while the robot is acting. Objective functions are …

Robots that can anticipate and learn in human-robot teams

MS Yasar, T Iqbal - … 17th ACM/IEEE International Conference on …, 2022 - ieeexplore.ieee.org
Robots are moving from working in isolated cham-bers to working in close-proximity with
human collaborator (s) as part of human-robot teams. In such situations, robots are …

Physical interaction as communication: Learning robot objectives online from human corrections

DP Losey, A Bajcsy, MK O'Malley… - … Journal of Robotics …, 2022 - journals.sagepub.com
When a robot performs a task next to a human, physical interaction is inevitable: the human
might push, pull, twist, or guide the robot. The state of the art treats these interactions as …

Learning robot objectives from physical human interaction

A Bajcsy, DP Losey, MK O'malley… - Conference on robot …, 2017 - proceedings.mlr.press
When humans and robots work in close proximity, physical interaction is inevitable.
Traditionally, robots treat physical interaction as a disturbance, and resume their original …

Enabling robots to infer how end-users teach and learn through human-robot interaction

DP Losey, MK O'Malley - IEEE Robotics and Automation …, 2019 - ieeexplore.ieee.org
During human-robot interaction, we want the robot to understand us, and we want to
intuitively understand the robot. In order to communicate with and understand the robot, we …

A dynamical system-based approach to modeling stable robot control policies via imitation learning

K Zadeh, S Mohammad - 2012 - infoscience.epfl.ch
Despite tremendous advances in robotics, we are still amazed by the proficiency with which
humans perform movements. Even new waves of robotic systems still rely heavily on …

Autonomous robotic reinforcement learning with asynchronous human feedback

M Balsells, M Torne, Z Wang, S Desai… - arXiv preprint arXiv …, 2023 - arxiv.org
Ideally, we would place a robot in a real-world environment and leave it there improving on
its own by gathering more experience autonomously. However, algorithms for autonomous …

Learning human objectives from sequences of physical corrections

M Li, A Canberk, DP Losey… - 2021 IEEE International …, 2021 - ieeexplore.ieee.org
When personal, assistive, and interactive robots make mistakes, humans naturally and
intuitively correct those mistakes through physical interaction. In simple situations, one …
