Abstract This paper proposed a distributed and hierarchical scheme for formation control of multiple robotic fish. Firstly, each robotic fish takes consensus algorithm as a distributed data fusion modular to estimate the center of the formation, and then calculate its desired position in the formation at the next time. Such estimated results are the input variables of its path planning modular. Secondly, each robotic fish tracking its desired position by employing the fuzzy controller of linear speed and angular speed in order to form and maintain formation. The proposed method separates the distributed estimation and the path planning and behavior of robotic fish, such a property gives a new method for the cooperative control of multiple heterogeneous robotic fish. The results of experiment shows the validity of the proposed method.
