HIO-SDF: Hierarchical Incremental Online Signed Distance Fields
Vasileios Vasilopoulos, Suveer Garg, Jinwook Huh +2
A good representation of a large, complex mobile robot workspace must be space-efficient yet capable of encoding relevant geometric details. When exploring unknown environments, it…
RAMP: Hierarchical Reactive Motion Planning for Manipulation Tasks Using Implicit Signed Distance Functions
Vasileios Vasilopoulos, Suveer Garg, Pedro Piacenza +2
We introduce Reactive Action and Motion Planner (RAMP), which combines the strengths of sampling-based and reactive approaches for motion planning. In essence, RAMP is a hierarchic…
Reactive Informative Planning for Mobile Manipulation Tasks under Sensing and Environmental Uncertainty
Mariliza Tzes, Vasileios Vasilopoulos, Yiannis Kantaros +1
In this paper we address mobile manipulation planning problems in the presence of sensing and environmental uncertainty. In particular, we consider mobile sensing manipulators oper…
Technical Report: A Hierarchical Deliberative-Reactive System Architecture for Task and Motion Planning in Partially Known Environments
Vasileios Vasilopoulos, Sebastian Castro, William Vega-Brown +2
We describe a task and motion planning architecture for highly dynamic systems that combines a domain-independent sampling-based deliberative planning algorithm with a global react…
Technical Report: Reactive Planning for Mobile Manipulation Tasks in Unexplored Semantic Environments
Vasileios Vasilopoulos, Yiannis Kantaros, George J. Pappas +1
Complex manipulation tasks, such as rearrangement planning of numerous objects, are combinatorially hard problems. Existing algorithms either do not scale well or assume a great de…
Reactive Navigation in Partially Familiar Planar Environments Using Semantic Perceptual Feedback
Vasileios Vasilopoulos, Georgios Pavlakos, Karl Schmeckpeper +2
This paper solves the planar navigation problem by recourse to an online reactive scheme that exploits recent advances in SLAM and visual object recognition to recast prior geometr…
Technical Report: Sensor-Based Reactive Symbolic Planning in Partially Known Environments
Vasileios Vasilopoulos, William Vega-Brown, Omur Arslan +2
This paper considers the problem of completing assemblies of passive objects in nonconvex environments, cluttered with convex obstacles of unknown position, shape and size that sat…
