MResT: Multi-Resolution Sensing for Real-Time Control with Vision-Language Models

no code implementations25 Jan 2024 Saumya Saxena, Mohit Sharma, Oliver Kroemer

Leveraging sensing modalities across diverse spatial and temporal resolutions can improve performance of robotic manipulation tasks.

Estimating Material Properties of Interacting Objects Using Sum-GP-UCB

no code implementations18 Oct 2023 M. Yunus Seker, Oliver Kroemer

Robots need to estimate the material and dynamic properties of objects from observations in order to simulate them accurately.

Efficient Recovery Learning using Model Predictive Meta-Reasoning

no code implementations27 Sep 2022 Shivam Vats, Maxim Likhachev, Oliver Kroemer

We use our approach to learn recovery skills for door-opening and evaluate them both in simulation and on a real robot with little fine-tuning.

Learning Reactive and Predictive Differentiable Controllers for Switching Linear Dynamical Models

no code implementations26 Mar 2021 Saumya Saxena, Alex LaGrassa, Oliver Kroemer

We learn a switching linear dynamical model with contacts encoded in switching conditions as a close approximation of our system dynamics.

Generalizing Object-Centric Task-Axes Controllers using Keypoints

no code implementations18 Mar 2021 Mohit Sharma, Oliver Kroemer

We empirically evaluate our approach on multiple different manipulation tasks and show its ability to generalize to large variance in object size, shape and geometry.

Relational Learning for Skill Preconditions

no code implementations3 Dec 2020 Mohit Sharma, Oliver Kroemer

Our work is motivated by the intuition that many complex manipulation tasks, with multiple objects, can be simplified by focusing on less complex pairwise object relations.

Learning to Compose Hierarchical Object-Centric Controllers for Robotic Manipulation

no code implementations9 Nov 2020 Mohit Sharma, Jacky Liang, Jialiang Zhao, Alex LaGrassa, Oliver Kroemer

Manipulation tasks can often be decomposed into multiple subtasks performed in parallel, e. g., sliding an object to a goal pose while maintaining contact with a table.

Towards Robotic Assembly by Predicting Robust, Precise and Task-oriented Grasps

no code implementations4 Nov 2020 Jialiang Zhao, Daniel Troniak, Oliver Kroemer

Robust task-oriented grasp planning is vital for autonomous robotic precision assembly tasks.

Multi-modal Transfer Learning for Grasping Transparent and Specular Objects

no code implementations29 May 2020 Thomas Weng, Amith Pallankize, Yimin Tang, Oliver Kroemer, David Held

State-of-the-art object grasping methods rely on depth sensing to plan robust grasps, but commercially available depth sensors fail to detect transparent and specular objects.

Camera-to-Robot Pose Estimation from a Single Image

2 code implementations21 Nov 2019 Timothy E. Lee, Jonathan Tremblay, Thang To, Jia Cheng, Terry Mosier, Oliver Kroemer, Dieter Fox, Stan Birchfield

We show experimental results for three different camera sensors, demonstrating that our approach is able to achieve accuracy with a single frame that is better than that of classic off-line hand-eye calibration using multiple frames.

Leveraging Multimodal Haptic Sensory Data for Robust Cutting

no code implementations27 Sep 2019 Kevin Zhang, Mohit Sharma, Manuela Veloso, Oliver Kroemer

In this paper, we propose using vibrations and force-torque feedback from the interactions to adapt the slicing motions and monitor for contact events.

Towards Precise Robotic Grasping by Probabilistic Post-grasp Displacement Estimation

no code implementations4 Sep 2019 Jialiang Zhao, Jacky Liang, Oliver Kroemer

Precise robotic grasping is important for many industrial applications, such as assembly and palletizing, where the location of the object needs to be controlled and known.

A Review of Robot Learning for Manipulation: Challenges, Representations, and Algorithms

no code implementations6 Jul 2019 Oliver Kroemer, Scott Niekum, George Konidaris

A key challenge in intelligent robotics is creating robots that are capable of directly interacting with the world around them to achieve their goals.
