“…However, 1 might also depend on the number Y of resting individuals, i.e., the individuals that have not already moved. This is the case, e.g., in sheep (Ovies aries: Pillot and Deneubourg 2010;. In this case, the probability 1 of an individual going in one direction is:…”

“…[A leader is "an individual eliciting strong follower behavior/ exerting social influence on others, by its rank into the progression, its behavior or its social status" (Pyritz et al, this issue)]. This raises the question of whether different rules underlie these different patterns, or whether they can be explained by a single rule in which the parameters, such as the probability of initiating a movement or the probability of following, vary according to individual characteristics (quantitative modulation instead of qualitative modulation, Pillot and Deneubourg 2010).…”

“…Here, we use data from previous studies and a simple mathematical model involving a theoretical group of 10 individuals to show how varying the parameters of a simple mimetic rule, i.e., an amplification process, can result in all the patterns observed during collective movements in primates and other species. First, we examine the simple case in which the needs of different individuals are identical and social relationships are equivalent between group members, as discussed by Pillot and Deneubourg (2010), and show that this physiological and social homogeneity results in strong anonymous mimetism when joining a movement. Second, we examine how biased leadership in favor of some individuals emerges through differences in the needs of group members.…”

Patterns of collective movements, such as the distribution of leadership and the organization of individuals, may be either homogeneously (no leader, no specific order), or heterogeneously (1 or several leaders, and a highly stable order) distributed. Members of a group need to synchronize their activities and coordinate their movements, despite the fact that they differ in physiological or morphological traits. The degree of difference in these traits may affect their decision-making strategy. We demonstrate how a theoretical model based on a variation of a simple mimetic rule, i.e., an amplification process, can result in each of the various collective movement patterns and decision-making strategies observed in primates and other species. We consider cases in which 1) the needs of different individuals are identical and social relationships are equivalent between group members, 2) the needs of individuals are different and social relationships are equivalent, and 3) the needs of individuals are different and social relationships are different. Finally, 4) we assess how the synergy between 2 mimetism rules, specifically the probability of joining a movement and that of canceling an initiation, allows group members to stay synchronized and cohesive. Our models suggest that similar self-organized processes have been selected as reliable and well-adapted means for optimal collective decisions across species, despite differences in their biological and social characteristics.

“…To solve this question, the classical approach combines theoretical models and experiments at the individual and collective levels. In some studies animals trained to perform specific movements were introduced to the group to study this link [6,7]. The alternative is a recent approach to use robotic devices to study animal behavior [8].…”

A robot introduced into an animal group, accepted by the animals as conspecifics, and capable of interacting with them is a very efficient tool for ethological research, particularly in studies of collective and social behavior. In this paper, we present the implementation of an autonomous mobile robot developed by the authors to study group behavior of chicks of the domestic chicken (Gallus gallus domesticus). We discuss the design of the robot and of the experimental setup that we built to run animal-robot experiments. The robot design was experimentally validated, it was demonstrated that the robot can be socially integrated into animal groups. The designed system opens new opportunities in the study of behavior in domestic fowl by using mobile robots. Being socially integrated into the animal group, mobile robots can profit from the positive feedback mechanism that plays key roles in animal collective behavior. They have potential applications in various domains, from pure scientific research to applied areas such as control and ensuring welfare of poultry.
