The current situation in the field of automation requires increasingly sophisticated flexible and adaptive solutions. Construction of modular machinery appears to be an effective tool to meet these requirements. Solution of design layout module with rotary motion linkage is designed for machines with unlimited rotary motion, based primarily on a modular concept. The main advantage of the proposed system is the possibility to compile from one module type the machines with different movement possibilities and degrees of freedom of movement for unrestricted use of the possibility of rotation of two adjacent modules, each associated rotary motion linkage.
