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…
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…
Dynamic Planning for Sequential Whole-body Mobile Manipulation
Zhitian Li, Yida Niu, Yao Su +2
The dynamic Sequential Mobile Manipulation Planning (SMMP) framework is essential for the safe and robust operation of mobile manipulators in dynamic environments. Previous researc…
Sequential Manipulation Planning on Scene Graph
Ziyuan Jiao, Yida Niu, Zeyu Zhang +3
We devise a 3D scene graph representation, contact graph+ (cg+), for efficient sequential task planning. Augmented with predicate-like attributes, this contact graph-based represen…
