Nowadays the automation of some industrial processes within the military system is a necessity, as this trend is accelerated by technological advances and thus must respond to the increasingly complex contemporary challenges of global security. Sorting is an extremely important process in almost any industrial area of use and it is essential that it is done in the right way so that productivity and flexibility of operations is increased. Over time, sorting with industrial robots has become an increasingly widespread and sophisticated technology, which has led to benefits in various industrial fields and manufacturing processes. This technology involves the use of robots with articulated arms or other mechatronic devices that follow the principle of modular interchangeability and are designed to pick, handle and sort different parts in an efficient and more accurate way. The desire to maximize flexibility, adaptability to changing industry requirements coupled with increased productivity has made robot arm sorting a necessary component of today's military industrial and manufacturing processes, and this technology continues to develop, opening up new opportunities in manufacturing automation. This paper presents the principle design of a flexible manufacturing line for sorting cartridges, served by a parallel robot with two degrees of freedom in the kinematic chain structure.

This article focuses on enhancing the range of motion (ROM) of the Tetra II joint, a spherical compliant joint consisting of three internally interconnected tetrahedron-shaped elements that achieve motion through elastic deformation. Despite its excellent precision, this specific design is constrained in terms of ROM due to internal contacts among the tetrahedral elements. To overcome this limitation, this study utilizes a computer-aided engineering (CAE) framework to optimize the configuration of the Tetra II joint and enhance its ROM. The resultant optimized joint, referred to as Tetra III, is subsequently compared to Tetra II in terms of both ROM and center shift. Finite element models (FEM) are employed to validate the optimization results and examine how various tetrahedron-shaped geometries impact the joint’s performance. The newly optimized joint exhibits a significantly higher ROM compared to the previous version, while maintaining excellent precision and overall smaller dimensions. Finally, to demonstrate its manufacturability, the Tetra III joint is produced using selective laser sintering (SLS) technology, with Duraform PA serving as the construction material. The successful fabrication serves as a demonstrative example of the improved design of the Tetra III joint.
