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.
