ABSTRACT: The issues of the wireless endoscopic capsule control are of great interest nowadays as it provides the more detailed analysis of the digestive track revealing pathologies and morphological changes. This article deals with the final selection of a method for controlling the endoscopic capsule inside the human body and electromagnetic parameters of the coils. The calculations of the physical parameters and the selection of the magnetic coils are provided. The authors consider three methods of the capsule control: the diamagnetic levitation in a magnetic field, the levitation of a permanent magnet in a minimum magnetic field with additional restrictions from external forces, and the method of "pushing" the magnet. According to the analysis of different options of the magnetic system for the capsule control the preferred one is "pushing" the permanent magnet magnetized perpendicular to the capsule axis of symmetry. The use of the patient movable table significantly reduces the requirements for the magnetic system. The article provides the calculations that will be used to create a prototype of the capsule endoscopic complex with magnetic control.
