Ultra-chaos of a mobile robot: a higher disorder than normal-chaos
Published in Chaos, Solitons & Fractals, 2022
This paper investigates the influences of small disturbances on chaotic navigation systems and the motion of mobile robots. It illustrates that while the chaotic navigation system of a mobile robot belongs to normal-chaos, the actual motion of a chaotic mobile robot exhibits ultra-chaos. Unlike normal-chaos, where statistical properties normally do not have sensitive dependence on small disturbances, ultra-chaos represents a higher-level disorder where tiny disturbances lead to huge deviations even in statistical meaning. This discovery highlights that ultra-chaos widely exists in practical applications and opens a new perspective for deepening the understanding of chaos theory.
