Non-Parametric Self-Identification and Model Predictive Control of Dexterous In-Hand Manipulation
Podshara Chanrungmaneekul, Kejia Ren, Joshua T. Grace +2
Building hand-object models for dexterous in-hand manipulation remains a crucial and open problem. Major challenges include the difficulty of obtaining the geometric and dynamical…
Kinodynamic Rapidly-exploring Random Forest for Rearrangement-Based Nonprehensile Manipulation
Kejia Ren, Podshara Chanrungmaneekul, Lydia E. Kavraki +1
Rearrangement-based nonprehensile manipulation still remains as a challenging problem due to the high-dimensional problem space and the complex physical uncertainties it entails. W…
Self-Supervised Unseen Object Instance Segmentation via Long-Term Robot Interaction
Yangxiao Lu, Ninad Khargonkar, Zesheng Xu +6
We introduce a novel robotic system for improving unseen object instance segmentation in the real world by leveraging long-term robot interaction with objects. Previous approaches…
Rearrangement-Based Manipulation via Kinodynamic Planning and Dynamic Planning Horizons
Kejia Ren, Lydia E. Kavraki, Kaiyu Hang
Robot manipulation in cluttered environments often requires complex and sequential rearrangement of multiple objects in order to achieve the desired reconfiguration of the target o…
