GaussTwin: Unified Simulation and Correction with Gaussian Splatting for Robotic Digital Twins

ICRA 2026poster

Digital twins promise to enhance robotic manipulation by maintaining a consistent link between real-world perception and simulation. However, most existing systems struggle with the lack of a unified model, complex dynamic interactions, and the real-to-sim gap, which limits downstream applications s…

Visual Imitation Learning of Task-Oriented Object Grasping and Rearrangement

IROS 2024poster

Task-oriented object grasping and rearrangement are key skills for robots, which have to perform versatile real-world manipulation tasks. However, they remain challenging due to partial observations of the objects and shape variations in categorical objects. In this paper, we present the Multi-featu…

Design and Development of a Hydrogel-based Soft Sensor for Multi-Axis Force Control

ICRA 2023poster

As soft robotic systems become increasingly complex, there is a need to develop sensory systems which can provide rich state information to the robot for feedback control. Multi-axis force sensing and control is one of the less explored problems in this domain. There are numerous challenges in the d…
