Verifiable Learned Behaviors via Motion Primitive Composition: Applications to Scooping of Granular Media

no code implementations26 Sep 2023 Andrew Benton, Eugen Solowjow, Prithvi Akella

If these component motion primitives are constructed according to the criteria we specify, the resulting behaviors are probabilistically verifiable.

Lipschitz Continuity of Signal Temporal Logic Robustness Measures: Synthesizing Control Barrier Functions from One Expert Demonstration

no code implementations7 Apr 2023 Prithvi Akella, Apurva Badithela, Richard M. Murray, Aaron D. Ames

By filtering control inputs to maintain the positivity of this function, we ensure that the system trajectory satisfies the desired STL specification.

Open-Ended Question Answering

Learning Disturbances Online for Risk-Aware Control: Risk-Aware Flight with Less Than One Minute of Data

no code implementations12 Dec 2022 Prithvi Akella, Skylar X. Wei, Joel W. Burdick, Aaron D. Ames

Recent advances in safety-critical risk-aware control are predicated on apriori knowledge of the disturbances a system might face.

Safety-Critical Controller Verification via Sim2Real Gap Quantification

no code implementations19 Sep 2022 Prithvi Akella, Wyatt Ubellacker, Aaron D. Ames

To develop more useful models, we quantify the inaccuracy with which a given model represents a system of interest, so that we may leverage this quantity to facilitate controller synthesis and verification.

Sample-Based Bounds for Coherent Risk Measures: Applications to Policy Synthesis and Verification

no code implementations21 Apr 2022 Prithvi Akella, Anushri Dixit, Mohamadreza Ahmadi, Joel W. Burdick, Aaron D. Ames

The dramatic increase of autonomous systems subject to variable environments has given rise to the pressing need to consider risk in both the synthesis and verification of policies for these systems.

A Scenario Approach to Risk-Aware Safety-Critical System Verification

no code implementations4 Mar 2022 Prithvi Akella, Mohamadreza Ahmadi, Aaron D. Ames

With the growing interest in deploying robots in unstructured and uncertain environments, there has been increasing interest in factoring risk into safety-critical control development.

A Barrier-Based Scenario Approach to Verify Safety-Critical Systems

no code implementations22 Feb 2022 Prithvi Akella, Aaron D. Ames

In this letter, we detail our randomized approach to safety-critical system verification.

Test and Evaluation of Quadrupedal Walking Gaits through Sim2Real Gap Quantification

no code implementations4 Jan 2022 Prithvi Akella, Wyatt Ubellacker, Aaron D. Ames

This dual approach has the added benefit of quantifying the Sim2Real Gap between a system simulator and its hardware counterpart.

Disturbance Bounds for Signal Temporal Logic Task Satisfaction: A Dynamics Perspective

no code implementations22 Oct 2021 Prithvi Akella, Aaron D. Ames

This letter offers a novel approach to Test and Evaluation of pre-existing controllers from a control barrier function and dynamics perspective.

Learning Performance Bounds for Safety-Critical Systems

no code implementations9 Sep 2021 Prithvi Akella, Ugo Rosolia, Aaron D. Ames

As a result, the test and evaluation ideal would be to verify the efficacy of a system simulator and use this verification result to make a statement on true system performance.
