Recent studies have been mainly engaged with movements by 2 or more autonomous robots.
Especially, the development of autonomous robots utilized by the industrial manufacture has been advancing.
However, the extent of these researches was limited to robots moving in 3 dimensional autonomous robots, such as airplanes or helicopters.
On the other hand, regarding studies on small size indoor 3 dimensional blimp robots, characteristics of entertainment robots, indoor surveillance robots, object searching robots in disaster building have been subject to investigation.
However, previous studies drew the attention to the difficulties arising when the cooperative behavior of 2 or more autonomous blimp robots is strongly presented depending on changes in the experimental environment, denoting the weak points of these systems.
In this paper, 2 small size autonomous blimp robots were used, and basic experiments with time constraints of behavior control were conducted, examining possible coordinated movements of 2 small size autonomous blimp robots, for the purpose of high application achievement of utility.
