Distributed Model-Based Diffusion For Scalable Multi-Robot Trajectory Optimization
Haejoon Lee, Xinyi Wang, Taekyung Kim +1
Trajectory optimization for multi-robot systems remains a critical challenge, particularly when navigating highly non-convex, non-linear, and non-differentiable environments. While…
Distributionally Robust Safety Under Arbitrary Uncertainties: A Safety Filtering Approach
Daniel M. Cherenson, Haejoon Lee, Taekyung Kim +1
We study how to ensure probabilistic safety for nonlinear systems under distributional ambiguity. Our approach builds on a backup-based safety filtering framework that switches bet…
Multi-Robot Allocation for Information Gathering in Non-Uniform Spatiotemporal Environments
Kaleb Ben Naveed, Haejoon Lee, Dimitra Panagou
Autonomous robots are increasingly deployed to estimate spatiotemporal fields (e.g., wind, temperature, gas concentration) that vary across space and time. We consider environments…
Enabling Safety for Aerial Robots: Planning and Control Architectures
Kaleb Ben Naveed, Devansh R. Agrawal, Daniel M. Cherenson +6
Ensuring safe autonomy is crucial for deploying aerial robots in real-world applications. However, safety is a multifaceted challenge that must be addressed from multiple perspecti…
Maintaining Strong r-Robustness in Reconfigurable Multi-Robot Networks using Control Barrier Functions
Haejoon Lee, Dimitra Panagou
In leader-follower consensus, strong r-robustness of the communication graph provides a sufficient condition for followers to achieve consensus in the presence of misbehaving agent…
