Abstract
The design scheme of a double spatial pendulum representing the main structural element of manipulators, pedipulators and other multi-link robotic devices is considered. The technique of geometric analysis of such two-link manipulator with non-collinear revolute joints through which the positions of its static equilibrium are located and their stability is determined, is described. The conclusions are drawn about the practical use of these equilibrium positions in the problems of statics and dynamics of revolute-joint manipulators.

Key words
Two-link manipulator, non-collinear axes, orthogonal pendulum, rotation matrix, Hessian, equilibrium, stability.
