文摘A decentralized information feedback mechanism was introduced to a group of mobile robots such that the robots asymptotically converge to a given moving formation.

In this paper, we firstly introduced a fundamental consensus algorithm for systems model and the cooperative control experimental platform,and then experimentally implemented and validated the formation control algorithm through setting transit point and lookup table method and so on.
