Content of the awarded research
SWARM is a multi-robot system utilizing the intelligence of a group demonstrated by ants, bees, and the like. For the communication device of a simple and compact SWARM used for underwater exploration, it is necessary to solve the problem of the characteristic changes of the electronic circuits due to the high water pressure in the deep sea, resulting in communication becoming impossible.
In this study, it was considered that nonlinear synchronous system would be effective, which synchronizes even when individuals have different time constants, following an example of fireflies that emit light synchronously in flocks. Then, a visible light communication device using the nonlinear synchronization system was developed. Next, it was confirmed that synchronization occured due to the nonlinear pull-in phenomenon even between devices with different time constants. In addition, the range of the time constant in which nonlinear synchronization occurs was investigated in three devices arranged in a ring. Furthermore, 4 PPM data communication was successfully demonstrated between devices with different time constants by using the nonlinear synchronization signal as a clock.
These research results can be expected to contribute to the field of ocean investigation, and to lead to the development of temperature measurement of seawaters and marine resource exploration etc. by using SWARM.
