Prototipo robótico para la desinfección de ambientes cerrados COVID

Abstract

An IoT robotic prototype applied for the fumigation of closed spaces with COVID was implemented, the same one that allows reducing the effort and infections of the personnel. The robot is made up of a caterpillar-type mobile platform, powered by 12v Pololu motors, it has an ESP32 camera with 180 degrees of freedom for visualization of the space to be sanitized, it has a 1.5-liter reservoir tank for liquids, a 4-cell LiPo battery at 4Amperes whose duration is 2 hours with a recharge of 1 hour, in addition the platform has the ability to move on floors such as tiles, concrete and not very pronounced irregular areas. To control the prototype we will do it remotely through 2 ways; (1) IoT control through the internet that allows the device to be tele-operated between cities or even countries (2) through an RF control that will be located where the prototype is going to carry out the fumigation, used in an emergency when it loses communication over the internet. The sanitizer module is derived from current domestic humidification systems, this system together with the combined sanitizer chemical compound (Quaternary Ammonium, Glycerin, Water), together form an important disinfectant option to include in future robotic platforms; It is important to note that the automatic option is configured so that the thermal fogger works continuously in case of losing the internet connection, which has a range of 1.50 to 2 meters. The use of fumigation by smoke agent has been gaining importance in recent years due to the global COVID-19 pandemic with the aim of reducing the impact of the virus. It was used for this study, it will finally incorporate sensors such as Air Quality, Temperature, etc, which are part of the telemetry of the IoT mobile robot.
