Dependency by Concentration of Pheromone Trail for Multiple Robots
نویسندگان
چکیده
In this paper, we discuss the concentration dependency of pheromone communication in swarm robotics. Instead of a pheromone trail and the insect antenna, we used ethanol and an alcohol sensor. This experimental system has a trade-off problem; high concentrations of the pheromone yield high signal strength but the signal duration is short, while low pheromone concentrations yield low signal strength but a long signal duration. We examined the optimal pheromone concentration for a swarm of robots. For this purpose, we developed a swarm behaviour algorithm and swarm robots that communicate using a pheromone trail. In addition, we discuss the effects of the pheromone concentration.

The Trail Pheromone of the Venomous Samsum Ant, Pachycondyla sennaarensis
Ant species use branching networks of pheromone trails for orientation between nest and resources. The current study demonstrated that workers of the venomous samsum ant, Pachycondyla sennaarensis (Mayr) (Hymenoptera: Formicidae: Ponerinae), employ recruitment trail pheromones discharged from the Dufour's gland. Secretions of other abdomen complex glands, as well as hindgut gland secretions, di...
متن کاملArgentine ants (Linepithema humile) use adaptable transportation networks to track changes in resource quality.
Transportation networks play a crucial role in human and animal societies. For a transportation network to be efficient, it must have adequate capacity to meet traffic demand. Network design becomes increasingly difficult in situations where traffic demand can change unexpectedly. In humans, network design is often constrained by path dependency because it is difficult to move a road once it is...
متن کاملAnt foraging on complex trails: route learning and the role of trail pheromones in Lasius niger.
Ants are central place foragers and use multiple information sources to navigate between the nest and feeding sites. Individual ants rapidly learn a route, and often prioritize memory over pheromone trails when tested on a simple trail with a single bifurcation. However, in nature, ants often forage at locations that are reached via more complex routes with multiple trail bifurcations. Such rou...
متن کاملAntbots: A Feasible Visual Emulation of Pheromone Trails for Swarm Robots
In this paper we present an experimental setup to model the pheromone trail based foraging behaviour of ants using a special phosphorescent glowing paint. We have built two custom addons for the e-puck robot that allow for trail laying and following on the glowing floor, as well as a way for the robots to mimic the ants capability of using polarization patterns as a means of navigation. Using s...
متن کاملSpatial and temporal variation in pheromone composition of ant foraging trails
Many social insects use pheromones to communicate and coordinate their activities. Investigation of intraspecific differences in pheromone use is a new area of social insect research. For example, interindividual variation in alarm pheromone content has been found in physical castes of polymorphic ants. Many ant species use multiple trail pheromones. Here we present novel research into trail ph...
