Abstract
Task execution in a dynamic environment is a challenging and important problem in multi-robot systems. In such an environment, the arrival time, location of a task, states and availability of robots are not known in advance. Recently a distributed algorithm for task execution in such an environment has been suggested. The distributed algorithm is supposed to be run on different components (robots) of the distributed system (multi-robot system) in an asynchronous model. It needs to be formally proved or verified that the algorithm behaves as expected. In this paper, formal modeling, verification, and analysis of the distributed algorithm are carried out. SPIN model checker is used for modeling and verification of the algorithm. We identify some interesting safety and liveness properties of the algorithm and perform extensive simulations of the algorithm. The verification results ascertain that the behavior of the algorithm is as expected.
