Scalable Trajectory Generation for Whole-Body Mobile Manipulation
Yida Niu, Xinhai Chang, Xin Liu +2
Robots deployed in unstructured environments must coordinate whole-body motion -- simultaneously moving a mobile base and arm -- to interact with the physical world. This coupled m…
Integrated Exploration and Sequential Manipulation on Scene Graph with LLM-based Situated Replanning
Heqing Yang, Ziyuan Jiao, Shu Wang +3
In partially known environments, robots must combine exploration to gather information with task planning for efficient execution. To address this challenge, we propose EPoG, an Ex…
IKDiffuser: a Diffusion-based Generative Inverse Kinematics Solver for Kinematic Trees
Zeyu Zhang, Ziyuan Jiao
Solving Inverse Kinematics (IK) for arbitrary kinematic trees presents significant challenges due to their high-dimensionality, redundancy, and complex inter-branch constraints. Co…
In-situ Value-aligned Human-Robot Interactions with Physical Constraints
Hongtao Li, Ziyuan Jiao, Xiaofeng Liu +2
Equipped with Large Language Models (LLMs), human-centered robots are now capable of performing a wide range of tasks that were previously deemed challenging or unattainable. Howev…
Integration of Robot and Scene Kinematics for Sequential Mobile Manipulation Planning
Ziyuan Jiao, Yida Niu, Zeyu Zhang +5
We present a Sequential Mobile Manipulation Planning (SMMP) framework that can solve long-horizon multi-step mobile manipulation tasks with coordinated whole-body motion, even when…
SuperMag: Vision-based Tactile Data Guided High-resolution Tactile Shape Reconstruction for Magnetic Tactile Sensors
Peiyao Hou, Danning Sun, Meng Wang +5
Magnetic-based tactile sensors (MBTS) combine the advantages of compact design and high-frequency operation but suffer from limited spatial resolution due to their sparse taxel arr…
