This paper presents a solution to the problem of steering a group of real omnidirectional mobile robots along a given path, while maintaining a desired formation pattern. ...
This problem can be divided into a leader agent subproblem and a follower agent subproblem such that a leader agent follows a given path and each follower agent tracks a trajectory, estimated by using ...
To guarantee control stability, many approaches have been investigated, e.g., using so called terminal region constraints and/or a terminal penalty term. ...
