A statistical method is used to separate periodic from non-periodic vibration peaks in autocorrelation spectra. Generally, an autocorrelation spectrum is not normally distributed because the amplitudes of periodic peaks are significantly large and random relative to the generally Gaussian noise. In a normally distributed signal, the statistical parameter kurtosis has a value of 3. The method sequentially removes each largest amplitude peak from the peaks in the spectrum until the kurtosis is 3 or less. The removed peaks, which are all considered to be periodic, are placed into a set. The total energy of the peaks in the set is considered to be the total periodic energy of the spectrum. As the process of building the peak set proceeds, if its total energy becomes greater than or equal to a predefined energy threshold before its kurtosis reaches 3 or less, the process stops and the periodic peak set is defined.

A class of robots specifically adapted to climb periodic lattices. These “relative robots” are designed for a specific lattice structure and use the regularity of the structure to simplify path planning, align with minimal feedback, and reduce the number of degrees of freedom (DOF) required to locomote. These robots can perform vital inspection and repair tasks within the structure that larger truss construction robots cannot perform without modifying the structure. A particular embodiment is a robot designed to traverse a cubooctahedral (CubOct) cellular solids lattice using only two motions: climbing and turning.
