Symbolic Regression on Sparse and Noisy Data with Gaussian Processes

no code implementations20 Sep 2023 Junette Hsin, Shubhankar Agarwal, Adam Thorpe, Luis Sentis, David Fridovich-Keil

To overcome this, we combine Gaussian process regression with a sparse identification of nonlinear dynamics (SINDy) method to denoise the data and identify nonlinear dynamical equations.

Learning Contact-based Navigation in Crowds

no code implementations2 Mar 2023 Kyle Morgenstein, Junfeng Jiao, Luis Sentis

This paradigm poses two problems: 1) freezing while navigating a crowd may cause people to trip and fall over the robot, resulting in more harm than the collision itself, and 2) in very dense social environments where collisions are unavoidable, such a control scheme would render the robot unable to move and preclude the opportunity to study how humans incorporate robots into these environments.

Sample Efficient Dynamics Learning for Symmetrical Legged Robots:Leveraging Physics Invariance and Geometric Symmetries

no code implementations13 Oct 2022 Jee-eun Lee, Jaemin Lee, Tirthankar Bandyopadhyay, Luis Sentis

Model generalization of the underlying dynamics is critical for achieving data efficiency when learning for robot control.

Learning to Walk by Steering: Perceptive Quadrupedal Locomotion in Dynamic Environments

1 code implementation19 Sep 2022 Mingyo Seo, Ryan Gupta, Yifeng Zhu, Alexy Skoutnev, Luis Sentis, Yuke Zhu

We present a hierarchical learning framework, named PRELUDE, which decomposes the problem of perceptive locomotion into high-level decision-making to predict navigation commands and low-level gait generation to realize the target commands.

Solving Service Robot Tasks: UT Austin Villa@Home 2019 Team Report

no code implementations14 Sep 2019 Rishi Shah, Yuqian Jiang, Haresh Karnan, Gilberto Briscoe-Martinez, Dominick Mulder, Ryan Gupta, Rachel Schlossman, Marika Murphy, Justin W. Hart, Luis Sentis, Peter Stone

RoboCup@Home is an international robotics competition based on domestic tasks requiring autonomous capabilities pertaining to a large variety of AI technologies.

Robust and Adaptive Door Operation with a Mobile Robot

1 code implementation25 Feb 2019 Miguel Arduengo, Carme Torras, Luis Sentis

In addition, we propose a versatile Bayesian framework that endows the robot with the ability to infer the door kinematic model from observations of its motion and learn from previous experiences or human demonstrations.
