A distributed motion coordination strategy for multiple nonholonomic mobile robots in cooperative hunting operations

摘要

This paper presents a distributed smooth time-varying feedback control law for coordinating motions of multiple nonholonomic mobile robots of the Hilare-type to capture/enclose a target by making troop formations. This motion coordination is a cooperative behavior for security against invaders in surveillance areas. Each robot in this control law has its own coordinate system and it senses a target/invader, other robots and obstacles, to achieve this cooperative behavior without making any collision. Each robot especially has a two-dimensional control input refereed to as a "formation vector" and the formation is controllable by the vectors. The validity of this control law is supported by computer simulations.
