Integrating Model-Based Control and RL for Sim2Real Transfer of Tight Insertion Policies

ICRA 2025

Object insertion under tight tolerances (<Imm) is an important but challenging assembly task as even small errors can result in undesirable contacts. Recent efforts focused on Reinforcement Learning (RL), which often depends on careful definition of dense reward functions. This work proposes an effe

PROBE: Proprioceptive Obstacle Detection and Estimation while Navigating in Clutter

ICRA 2025

In critical applications, including search-and-rescue in degraded environments, blockages can be prevalent and prevent the effective deployment of certain sensing modalities, particularly vision, due to occlusion and the constrained range of view of onboard camera sensors. To enable robots to tackle

Visuotactile-Based Learning for Insertion With Compliant Hands

RA-L 2025

Compared to rigid hands, underactuated compliant hands offer greater adaptability to object shapes, provide stable grasps, and are often more cost-effective. However, they introduce uncertainties in hand-object interactions due to their inherent compliance and lack of precise finger proprioception a

Mono-STAR: Mono-Camera Scene-Level Tracking and Reconstruction

ICRA 2023poster

We present Mono-STAR, the first real-time 3D reconstruction system that simultaneously supports semantic fusion, fast motion tracking, non-rigid object deformation, and topological change under a unified framework. The proposed system solves a new optimization problem incorporating optical-flow-base…
