Safety-aware Model Predictive Path Integral Control with Signal Temporal Logic
Yiqi Zhao, Taekyung Kim, Hideki Okamoto +4
Safety-aware motion planning remains a challenge in robotics, especially when missions are time-critical and are under complex specifications. In this paper, we propose safety-awar…
Multi-Agent Planning with Spatio-Temporal and Topological Constraints using STL-GO
Sheryl Paul, Vidisha Kudalkar, Anand Balakrishnan +3
Multi-agent planning problems arise in a variety of engineering applications, such as multi-robot wildfire fighting and unmanned aerial inspection in factories. A particular challe…
An Algebraic Framework for Quantitative Semantics of Spatio-Temporal Logic with Graph Operators
Sheryl Paul, Vidisha Kudalkar, Anand Balakrishnan +3
Spatio-Temporal Logic with Graph Operators (STL-GO) extends Signal Temporal Logic (STL) to multi-agent systems via graph operators that count neighboring agents satisfying a proper…
A Reactive Redistribution Mechanism for STL Tasks in Multi-Agent Systems Under Time-Varying Communication
Gregorio Marchesini, Bjarne Jan Jesse Moro, Siyuan Liu +2
We present a communication-aware task decomposition framework for multi-agent systems with collaborative relative configuration objectives specified in Signal Temporal Logic (STL),…
UMBRELLA: Uncertainty-aware Multi-robot Reactive Coordination under Dynamic Temporal Logic Tasks
Qisheng Zhao, Meng Guo, Hengxuan Du +2
Multi-robot systems can be extremely efficient for accomplishing team-wise tasks by acting concurrently and collaboratively. However, most existing methods either assume static tas…
Spatiotemporal Robustness of Temporal Logic Tasks using Multi-Objective Reasoning
Oliver Schön, Lars Lindemann
The reliability of autonomous systems depends on their robustness, i.e., their ability to meet their objectives under uncertainty. In this paper, we study spatiotemporal robustness…
