Simultaneous Task Allocation and Planning for Multi-Robots under Hierarchical Temporal Logic Specifications

1 code implementation8 Jan 2024 Xusheng Luo, Changliu Liu

Past research into robotic planning with temporal logic specifications, notably Linear Temporal Logic (LTL), was largely based on singular formulas for individual or groups of robots.

Past research into robotic planning with temporal logic specifications, notably Linear Temporal Logic (LTL), was largely based on singular formulas for individual or groups of robots.

Formal Verification of Stochastic Systems with ReLU Neural Network Controllers

no code implementations8 Mar 2021 Shiqi Sun, Yan Zhang, Xusheng Luo, Panagiotis Vlantis, Miroslav Pajic, Michael M. Zavlanos

Using this abstraction, we propose a method to compute tight bounds on the safety probabilities of nodes in this graph, despite possible over-approximations of the transition probabilities between these nodes.

Temporal Logic Task Allocation in Heterogeneous Multi-Robot Systems

no code implementations14 Jan 2021 Xusheng Luo, Michael M. Zavlanos

To obtain a scalable solution to this complex temporal logic task allocation problem, we propose a hierarchical approach that first allocates specific robots to tasks using the information about the tasks contained in the Nondeterministic Buchi Automaton (NBA) that captures the LTL specification, and then designs low-level executable plans for the robots that respect the high-level assignment.
