The paper proposes a procedure to estimate the parameters of experimental manipulator robot samples in a series of tests that allows discarding robot samples with parameters being unsuitable for the constructed mechanism. Features of this approach, providing numerical estimates of the parameters are particularly useful in solving the problems of designing space manipulators that require a higher degree of reliability performance. This procedure can also be used in other practice areas, such as analysis of indirect signs of corruption in the socioeconomic, financial, military, geopolitical and other structures.
