Latent Activation Editing: Inference-Time Refinement of Learned Policies for Safer Multirobot Navigation

ICRA 2026poster

Reinforcement learning has enabled significant progress in complex domains such as coordinating and navigating multiple quadrotors. However, even well-trained policies remain vulnerable to collisions in obstacle-rich environments. Addressing these infrequent but critical safety failures through retr…

SAFE-GIL: SAFEty Guided Imitation Learning for Robotic Systems

ICRA 2025

Behavior cloning (BC) is a widely used approach in imitation learning where a robot learns a control policy by observing an expert supervisor. However the learned policy can make errors and might lead to safety violations which limits their utility in safety-critical robotics applications. While pri

Optimization and Evaluation of a Multi Robot Surface Inspection Task Through Particle Swarm Optimization

ICRA 2024poster

Robot swarms can be tasked with a variety of automated sensing and inspection applications in aerial, aquatic, and surface environments. In this paper, we study a simplified two-outcome surface inspection task. We task a group of robots to inspect and collectively classify a 2D surface section based…
