Periodic inspections of nuclear power plants often use the visual inspection method, in which the degree of decomposition of a component is estimated on the basis of images or videos. At inspection points where access is not possible due to excessive radiation a use of dedicated tools or remote control systems are required. The aim of the task is to develop and manufacture remotely controlled mobile robot for performing visual
inspections of the reactor head and to test it on the polygon. 3D printing technology was used for prototyping and manufacturing robot, where we selected the most suitable material for the enviroment where the robot will be performing tasks on the basis of mechanical, chemical and temperature properties. To carry out the inspections, it was necessary to select an appropriate camera. Furthermore the primary electronic components had to be selected: a microcontroller and drivers to control the mobile robot, and a microcomputer to communicate with the operator. All software interfaces for robot control, image transfer and capture had been developed. An application that connects the entire operation of the system to make it easier for the operator to use the robot was created. The mobile robot was tested on the polygon and was exposed to ionizing radiation. Thus, we tested the adequacy of the images captured by the
camera on the robot.
