Learning Multi-Stage Pick-and-Place With a Legged Mobile Manipulator

RA-L 2025

Quadruped-based mobile manipulation presents significant challenges in robotics due to the diversity of required skills, the extended task horizon, and partial observability. After presenting a multi-stage pick-and-place task as a succinct yet sufficiently rich setup that captures key desiderata for

DisMech: A Discrete Differential Geometry-Based Physical Simulator for Soft Robots and Structures

RA-L 2024

Fast, accurate, and generalizable simulations are a key enabler of modern advances in robot design and control. However, existing simulation frameworks in robotics either model rigid environments and mechanisms only, or if they include flexible or soft structures, suffer significantly in one or more

Integrating Deep Metric Learning with Coreset for Active Learning in 3D Segmentation

NeurIPS 2024poster

Deep learning has seen remarkable advancements in machine learning, yet it often demands extensive annotated data. Tasks like 3D semantic segmentation impose a substantial annotation burden, especially in domains like medicine, where expert annotations drive up the cost. Active learning (AL) holds g…

mBEST: Realtime Deformable Linear Object Detection Through Minimal Bending Energy Skeleton Pixel Traversals

RA-L 2023

Robotic manipulation of deformable materials is a challenging task that often requires realtime visual feedback. This is especially true for deformable linear objects (DLOs) or “rods”, whose slender and flexible structures make proper tracking and detection nontrivial. To address this challenge, we

Preemptive Motion Planning for Human-to-Robot Indirect Placement Handovers

ICRA 2022poster

As technology advances, the need for safe, efficient, and collaborative human-robot-teams has become increasingly important. One of the most fundamental collaborative tasks in any setting is the object handover. Human-to-robot handovers can take either of two approaches: (1) direct hand-to-hand or (…
