Scalable time-constrained planning of multi-robot systems

Abstract: This paper presents a scalable procedure for time-constrained planning of a class of uncertain nonlinear multi-robot systems. In particular, we consider N robotic agents operating in a workspace which contains regions of interest (RoI), in which atomic propositions for each robot are assigned. The main goal is to design decentralized and robust control laws so that each robot meets an individual high-level specification given as a metric interval temporal logic (MITL), while using only local information based … Show more

“…For the sake of clarity, we use a gridworld in the examples, but our approach applies to any WTS, obtained e.g. through triangulation [20] or other cell partitioning methods [19], discrete abstraction of a robot's dynamics, and estimate of travel time of between the cells.…”

“…During the execution step, R 0 implements two rounds of pursuitevasion strategy in the workspace to exchange all requests while R i , i ∈ [1, N ] executes their timed runs in parallel independently (line 9-10). Robots R i , i ∈ [1, N ] then update their tasks and proceed with execution (line [11][12][13][14][15][16][17][18][19] If there exists N timed runs ρ i |= ϕ ′ i ∧ j̸ =i ϕ j,i , ∀i ∈ [1, N ], the joint run satisfying all mission specifications φ i , ∀i ∈ [1, N ] is found (line 20).…”

“…Multi-robot hunting is one of the most important and complex challenges in the field of multi-robot cooperation due to the fact that it includes all multi-robot system subproblems such as task allocation, target localization, collaborative pursuing, obstacle and collisions avoidance. The research on multi-robot system cooperative hunting covers many disciplines and domain knowledge, such as optimization algorithms [8], real-time dynamic path planning [9]- [10], multi-robot coordination [11]- [13], planning and learning [14], and communication [15].…”
