Formation control of force-controlled mobile robots in a spanning-tree topology

چکیده
We solve the formation-tracking control problem for mobile robots via linear control, under the assumption that each agent communicates only with one “leader” robot and with one follower. We assume that the system is forcecontrolled (hence we use the dynamic model) as opposed to velocity-controlled (in the kinematic-model case). As in the classical tracking control problem for nonholonomic systems, the swarm is driven by a fictitious robot which moves about freely and which is leader to one robot only. For the case of a fixed spanning-tree topology we show that persistency of excitation on the velocity of the virtual leader is sufficient and necessary to achieve consensus tracking.

Dynamical formation control of wheeled mobile robots based on fuzzy logic
In this paper, the important formation control problem of nonholonomic wheeled mobile robots is investigated via a leader-follower strategy. To this end, the dynamics model of the considered wheeled mobile robot is derived using Lagrange equations of motion. Then, using ADAMS multi-body simulation software, the obtained dynamics of the wheeled system in MATLAB software is verified. After that, ...

متن کاملCooperative Control of Mobile Robots in Creating a Runway Platform for Quadrotor Landing
Multi-agent systems are systems in which several agents accomplish a mission in a cooperative manner. In this paper, a novel idea for the construction of a movable runway platform based on multi-agent systems is presented. It is assumed that an aerial agent (quadrotor) decides to make an emergency landing due to reasons such as a decrease in energy level or technical failure, while there is no ...
