Commercial Entry Control Using Robotic Mechanism and Mobile Application for COVID-19 Pandemic

The control of entry to commercial premises has always existed, but with the pandemic, this has been adapted to include biosecurity measures that guarantee the safety of customers. Technology makes it possible to automate these activities, among the most popular tools are mobile applications that allow easy implementation and good reception from users. This work presents the entrance control to a commercial premise using a robotic mechanism and a mobile application connected through a cloud database. The system is implemented using accessible and low-cost components, among the tools are 3D printing, the ESP32 board, servo motors, proximity sensors, temperature, and heart rate. The mobile application is developed in App Inventor and Firebase is used for the remote database. The system automates the provision of hand sanitizer at the entrance and records these vital signs of the customers, allowing to generate a report of the attendees. The results show the readings carried out by validating the implemented system and a measure of acceptance of this technology is applied with a score of 73%, evidencing the deficiencies of the proposal from the users' perspective.
