Modular robot interface for a smart operating theater

This paper discusses the architecture and implementation of a modular component of the smart operating theater digital twin, designed to control robotic equipment—the robot interface module. This interface is designed to ensure equipment operation both in a real smart operating theater and in the virtual space of its digital twin—the computer simulation. Using such an interface in the digital twin will make it possible to use it in computer-assisted training of surgeons, preliminary planning, post-analysis, and simulation, preceding the operation of real equipment. An experimental implementation of a prototype robot interface to enable the KUKA LBR Med 14 R820 medical robot operation using the FRI protocol was developed, and experiments were performed on real equipment and its digital twin.
