This paper deals with a collision avoidance problem in leader-following formation navigation for multiple mobile robots. Because followers should move along a leader’s trajectory, we first try to avoid collisions by adjusting their velocities on the trajectory. This strategy causes delays of the followers from the leader, which is often problematic because we cannot predict how late the followe...

this paper aims to investigate a new and intricate behavior of immediate follower during the lane change of leader vehicle. accordingly, the mentioned situation is a transient state in car following behavior during which the follower vehicle considerably deviates from conventional car following models for a limited time, which is a complex state including lateral and longitudinal movement simul...

The leader-following consensus problemof higher ordermulti-agent systems is considered. In the system, the dynamics of each agent and the leader is a linear system. The control of each agent using local information is designed and detailed analysis of the leader-following consensus is presented for both fixed and switching interaction topologies, which describe the information exchange between ...

Through the use of a virtual tractor-trailer link model, vehicle following capabilities have been implemented without the need of communications links between the two vehicles or the installation of special road infrastructure. The principle is based on the modeling of an off-hooked trailer system as a software link between the lead and led vehicles. The leader vehicle is modeled as the tractor...

In this paper, we consider a leader-following consensus problem for networks of continuous-time integrator agents with a time-varying leader under measurement noises. We propose a neighbor-based state-estimation protocol for every agent to track the leader, and time-varying consensus gains are introduced to attenuate the noises. By combining the tools of stochastic analysis and algebraic graph ...

Survived strategies after 100 thousand generations share the following three common policies among simulation runs: (1) Do not give your way before the opponent does once you have consecutively failed coordinating your action with the opponent’s. (2) If you remember you have gone through the experience of a leader, behave aggressively. (3) If you have not had an experience as a leader, and if t...
