A multi-robot formation composed of autonomous agents may need to maintain an overall rigid shape for tasks such as collective transport of an object. To distribute control, we construct leader-follow formations in the plane that are persistent: designated “leader” robots control the movement of the entire formation, while the remaining “follower” robots maintain directed local links sensing da...

This paper proposes an intelligent formation control method of the leader and follower agents with nonlinear dynamics. In the proposed method, agents can exchange only information of positions of available agents and the follower agents follow the leader, taking a predefined formation. In the real world, the method that doesn’t need a lot of information to make cooperative behaviors is very use...

In this paper, we present a full scheme for the cooperative control of multiple unmanned aerial vehicle (UAV) helicopters. We adopt the leader-follower pattern to maintain a fixed geometrical formation while navigating the UAVs following certain trajectories. More specifically, the leader is commanded to fly on some predefined trajectories, and each follower is controlled to maintain its positi...

This paper describes the design and implementation of a lead and follow dance to be performed with a human follower and PHANToM leader, or executed by two humans via two PHANToMs, reciprocally linked. In some contexts, such as teaching calligraphic character writing, haptic-only communication of information has demonstrated limited effectiveness. This project was inspired by the observation tha...

Contrary to most of the papers in the literature of investment under uncertainty we study models that not only capture the timing, but also the size of the investment. We consider a monopoly setting as well as a duopoly setting and compare the results with the standard models in which the firms do not have the capacity choice. Our main results are the following. First, for low uncertainty value...

In this article we address the problem of mobile robot formation control. Indeed, the most work, in this domain, have studied extensively classical control for keeping a formation of mobile robots. In this work, we design an FLC (Fuzzy logic Controller) controller for separation and bearing control (SBC). Indeed, the leader mobile robot is controlled to follow an arbitrary reference path, and t...

Pedestrian following is a common behavior, and may provide a key link between individual locomotion and crowd dynamics. Here, we present a model for following that is motivated by cognitive science and grounded in empirical data. In Experiment 1, we collected data from leader-follower pairs, and showed that a simple speed-matching model is sufficient to account for behavior. In Experiment 2, we...

In a series of studies, we examine the role of positive emotions in the charismatic leadership process. In Studies 1 and 2, ratings of charisma in a natural work setting were linked to leaders' positive emotional expressions. In Study 3, leaders' positive emotional expressions were linked to mood states of simulated followers. Results suggest that mood contagion may be one of the psychological ...

We propose a model where two competitors, a Leader and a Follower, are sequentially creating their hub and spoke networks and setting prices. The existence of the unique Stackelberg and Nash pricing equilibria is shown. On the basis of these results we give the conclusion about existence of the profit maximising solution for the Leader.

Purpose This study aims to build a moderated mediation model investigate the roles that trust in leader and follower Machiavellianism can play relationship between moral disengagement of hiding knowledge followers. Design/methodology/approach Data were gathered from eight universities Turkey using set 72 matched (dean)–follower (faculty member) questionnaires. The hypotheses tested with multipl...
