Design of a mobile robot to support workers in high-risk environments

This study presents a design concept for a hybrid tracked mobile robot intended to replace human operators in high-risk environments, including exposure to hazardous chemicals, gas storage facilities, high-temperature zones, and areas prone to fire and explosions. The structural design of a mobile robot with a combined propulsion system was developed and analyzed. Design and modeling were performed in SolidWorks. The study included layout design calculations and assessments of obstacle-traversal stability, robot mobility, and slope-climbing capability. It also involved the selection of appropriate sensors and auxiliary equipment. The RoSafe robot model was developed within the framework of the DTAV.04/25-NN ministerial project. The robot features a hybrid chassis configuration comprising two primary tracks and four auxiliary tracked legs. The complete 3D and 2D design documentation specifies overall dimensions of 1311 × 649.2 × 350.3 mm and a calculated mass of 130 kg. In addition, a table of technical specifications is provided. The robot is equipped with gas sensors (O 2 , CO, CO 2 , CH 4 , and H 2 S), temperature sensors, smoke sensors, surveillance cameras, a mapping system, bidirectional communication with the control center, and manipulator mechanisms. Particular attention during the design process was given to obstacle-negotiation capability, stability on inclined surfaces, compactness, and operational convenience, ensuring practical applicability of the system. This work represents the initial stage of development, and the results provide a foundation for subsequent pilot production and testing aimed at the practical implementation of the RoSafe robot model.
