Team movement control, including navigation and path-following, are fundamental functions for mobile robots carrying out environmental monitoring and sampling tasks. New challenges arise when control algorithms have to be designed for a team of robots with limited communication capacity and the environment may contain obstacles. In this talk, I show how to design guiding vector fields to enable motion coordination among robots; I also show how to construct composite guiding vector fields to avoid colliding with obstacles of arbitrary shapes. Both theoretical guarantees and experimental validations are discussed for practical scenarios.
