Chemical Plume Tracing
Given a measurable concentration of a dissolved substance at a point within a fluid flow, where is the source? As physicists and engineers we often look at this problem from a more traditional perspective given a point source release of a substance, we seek to describe the temporal and spatial evolution of the effluent plume. Animals, seeking to evade predators or to locate mates or sources of ...
متن کاملChemical Plume Tracing and Mapping via Swarm Robots
This chapter addresses the key issues of chemical plume mapping and tracing via swarm robots. First, the authors present the models of turbulent odor plumes with both non-buoyant and buoyant features, which can efficiently evaluate strategies for tracing plumes, identifying their sources in two or threedimensions. Second, the authors use the Monte Carlo technique to optimize moth-inspired plume...
متن کاملAgent-Based Chemical Plume Tracing Using Fluid Dynamics
This paper presents a rigorous evaluation of a novel, distributed chemical plume tracing algorithm. The algorithm is a combination of the best aspects of the two most popular predecessors for this task. Furthermore, it is based on solid, formal principles from the field of fluid mechanics. The algorithm is applied by a network of mobile sensing agents (e.g., robots or micro-air vehicles) that s...
متن کاملChemical Plume Tracing Experimental Results with a REMUS AUV
Olfactory-based mechanisms have been hypothesized for biological behaviors including foraging, mateseeking, homing, and host-seeking. Typically, olfactorybased mechanisms proposed for biological entities combine a large-scale orientation behavior based in part on olfaction with a multisensor local search in the vicinity of the source. Long-range olfactory based search is documented in moths at ...
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...
