Abstract—Currently, Explosive Ordnance Disposal (EOD) operations are more reliable and safer due to the incorporation of EOD robots. These robots typically operate in uneven urban terrain with obstacles, as well as in extreme temperature conditions, which cause severe damage to the robots’ control and operating systems. This article presents the modeling and analysis of an Electronic Enclosure for EOD robots adapted to uneven terrain and extreme thermal conditions. The JVC-02 robot, developed collaboratively by the National University of San Agustín (UNSA) and the Arequipa Explosive Ordnance Disposal Unit (UDEX-AQP), was taken as a case study. Taking as a reference the characteristics of the control and operation system of this robot, to develop a first prototype of an Electronic Enclosure based on aluminum profiles, which allowed the identification of technical problems caused by impacts and vibrations of the chassis when passing through uneven terrain accompanied by extreme thermal conditions. An improved Electronic Enclosure was then modeled and adapted to the requirements of the JVC02 robot. This version has a modular design that facilitates maintenance, as well as an open structure for adequate ventilation of the components and a system that cushions impacts and vibrations during the robot’s locomotion. The model was analyzed using the Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) methods, which allowed critical stresses and thermal loads to be identified in the prototype. The results show that adopting an Electronic Enclosure with the CFD-FEA method offers a viable solution for protecting the control and operating systems of EOD robots against impact loads and thermal effects, as well as providing maintenance improvements due to its modularity.
