Warm-Starting Collision-Free Model Predictive Control With Object-Centric Diffusion

RA-L 2026

Acting in cluttered environments requires predicting and avoiding collisions while still achieving precise control. Conventional optimization-based controllers can enforce physical constraints, but they struggle to produce feasible solutions quickly when many obstacles are present. Diffusion models

Temporally Consistent Object 6D Pose Estimation for Robot Control

RA-L 2025

Single-view RGB object pose estimators have reached a level of precision and efficiency that makes them good candidates for vision-based robot control. However, off-the-shelf methods lack temporal consistency and robustness that are mandatory for a stable feedback control. In this work, we develop a

Collision Detection Accelerated: An Optimization Perspective

RSS 2022poster

Collision detection between two convex shapes is an essential feature of any physics engine or robot motion planner. It has been often tackled as a computational geometry problem, with the Gilbert, Johnson and Keerthi (GJK) algorithm being the most common approach today. In this work we show that co…

Learning Object Manipulation Skills from Video via Approximate Differentiable Physics

IROS 2022poster

We aim to teach robots to perform simple object manipulation tasks by watching a single video demonstration. Towards this goal, we propose an optimization approach that outputs a coarse and temporally evolving 3D scene to mimic the action demonstrated in the input video. Similar to previous work, a…

Learning to Manipulate Tools by Aligning Simulation to Video Demonstration

RA-L 2022

A seamless integration of robots into human environments requires robots to learn how to use existing human tools. Current approaches for learning tool manipulation skills mostly rely on expert demonstrations provided in the target robot environment, for example, by manually guiding the robot manipu

Learning Object Manipulation Skills via Approximate State Estimation from Real Videos

CoRL 2020

Humans are adept at learning new tasks by watching a few instructional videos. On the other hand, robots that learn new actions either require a lot of effort through trial and error, or use expert demonstrations that are challenging to obtain. In this paper, we explore a method that facilitates lea

Automatic Material Properties Estimation for the Physics-Based Robotic Garment Folding

ICRA 2018poster

The estimation of the fabric material property during the folding is presented. The available techniques for the accurate garment folding rely on known material properties. Currently, the properties are estimated by an operator in advance of folding. We propose an iterative strategy, which updates t…

Model-free approach to garments unfolding based on detection of folded layers

IROS 2017poster

The proposed work deals with robotic unfolding of a garment that has been placed flat on a table and folded over a certain axis. The algorithm combines image and depth data to detect the bottom and top (folded) layer of the garment. The detection is formulated as a labeling of the garment surface an…

Physics-based model of a rectangular garment for robotic folding

IROS 2016poster

The ability to perform an accurate robotic fold is essential to obtain the properly folded garment. Available solutions rely on a rough folding surface or on a comprehensive simulation, both preventing the garment from slipping on the table during folding. This paper proposes a new algorithm for a f…
