Analysis of environment´s vibro-acoustic expressions by robot

There are certain situations when the robot´s ability to evaluate the vibro-acoustic expressions from an environment is important. In the area where the robot moves there can occur the sources of the acoustic or vibrating emissions, which has got their own specific parameters. The character´s modification of these expressions could require an adequate robot reaction. To this purpose, it is necessary to find the fast and clear algorithms that will be able to reliably detect the deviation of the vibro-acoustic expressions from its stationary state. The article suggests as a highly convenient to use the Hilbert´s spaces as a solution to this problem.
