The motion reliability analysis of a series system with multiple coordinated manipulators

Coordinated manipulators can construct a series system, such that all the position error of end-effector is required to remain within permissible limit. This article proposed new method handle problem reliability analysis involving in multiple failure modes. The extreme value introduced surrogate model replace original event, moment with fraction order instead traditional integer applied derive best-fit distribution based on maximum entropy principle. innovations mainly include: (1) high efficient dimension reduction via constructed and (2) better probability density function derived through fractional moment. A system consists three used as an example demonstrate efficiency accuracy method.
