In this work, we propose a low-cost teleoperable laboratory architecture, in which we integrate a palette of dynamic processes accessible via a mobile platform. In the current health context, our goal is to promote learning in engineering in developing countries via remote laboratories with a low-cost architecture. In this architecture accessible via wifi on a mobile platform, we use an ESP32 microcontroller as master, an ESP-CAM for visual feedback on our processes and several ESP32 microcontrollers as slave depending on the number of processes on our palette. We have chosen the ARDUINO NANO microcontroller to manage each process of the pallet. To test our architecture, we have integrated a process of visualization of the curves of variation of the current and the voltage of the brushless direct current motor according to the speed level. Using experimental methods, the error variations between the values measured with the tachometer and those found by calculation are between 0.00094 and 0.0350. Thus, the PWM setpoint delivered by our architecture is indeed equivalent to the output speed.

Abstract: (french)
Dans ce travail, nous proposons une architecture de laboratoire téléopérable à faible coût, dans laquelle nous intégrons une palette de processus dynamiques accessible via une plateforme mobile. Dans le contexte sanitaire actuel, notre but est de favoriser les apprentissages en ingénierie dans les pays en voie de développement via des laboratoires distants avec une architecture à faible coût. Dans cette architecture accessible en wifi sur plateforme mobile, nous utilisons un microcontrôleur ESP32 comme maître, un ESP-CAM pour le retour visuel sur nos processus et plusieurs microcontrôleurs ESP32 comme esclave selon le nombre de processus de notre palette. Nous avons choisi le microcontrôleur ARDUINO NANO pour gestion de chaque processus de la palette. Pour éprouver notre architecture, nous avons intégré un processus de visualisation des courbes de variation du courant et de la tension du moteur à courant continu brushless en fonction du niveau de vitesse. A l’aide des méthodes expérimentales, les variations d’erreurs entre les valeurs mesurées avec le tachymètre et celles retrouvées par calcul, sont comprises entre 0,00094 et 0,0350. Ainsi, la consigne PWM délivré par notre architecture est bien équivalente à la vitesse en sortie.
