Virtual Physics Framework for Multi-Robot Chemical Plume Tracing under Ventilated Indoor Condition

چکیده
This paper presents a virtual-physics based control framework for swarm robotic chemical plume tracing and source localization problem under ventilated indoor environment with complex turbulent conditions. The control force includes three kinds of effort, which are lattice formation force, plume tracing force, and obstacle avoidance force. The plume tracing and source identify strategy are based on the chemical mass flux passing through the robot colony. Simulation results show that the proposed control framework and tracing strategy can effectively navigate the multi-robot system to the chemical source emitter region. The virtual-physics based framework is highly flexible, endows the robot formation the properties of self-organization and self-repair. Compare to traditional approaches, the mass flux driven plume tracing can inhibit the robots from adhering to the obstacle-induced local density maxima and guide the robots forward to the real source region. Streszczenie. W artykule opisano metodę śledzenia smugi dymu chemicznego przy wykorzystaniu robotów oraz metodę wykrywania źródła dymu w pomieszczeniu wentylowanym przy zawirowaniu powietrza. Stosowane są trzy środki – określenie siatki, śledzenie dymu i eliminacja zjawiska. Roboty śledzące mogą się same organizować i naprawiać. W porównaniu do innych metod zaproponowana metoda zabezpiecza roboty przed zatrzymaniem się przy lokalnym maksimum i prowadzi je do źródła dymu. (Wykorzystanie multi-robotów do śledzenia dymu w wentylowanych pomieszczeniach)

Adapting an Ant Colony Metaphor for Multi-Robot Chemical Plume Tracing
We consider chemical plume tracing (CPT) in time-varying airflow environments using multiple mobile robots. The purpose of CPT is to approach a gas source with a previously unknown location in a given area. Therefore, the CPT could be considered as a dynamic optimization problem in continuous domains. The traditional ant colony optimization (ACO) algorithm has been successfully used for combina...

متن کاملLearning to Rapidly Re-Contact the Lost Plume in Chemical Plume Tracing
Maintaining contact between the robot and plume is significant in chemical plume tracing (CPT). In the time immediately following the loss of chemical detection during the process of CPT, Track-Out activities bias the robot heading relative to the upwind direction, expecting to rapidly re-contact the plume. To determine the bias angle used in the Track-Out activity, we propose an online instanc...
