Abstract The following project presents an autonomous system of classification of objects by colors which it is applied to the caps of plastic bottles, emulating an automated work cell, which serves to students to know the operation of industrial processes, from construction, programming and even maintenance point of view. The entire project consists of the design of a conveyor system which has a sensor to identify colors, and actuators which allow the caps are correctly classified in the containers according to its color. The work cell was built in a modular way in such a way that in the future it can be adapted to other work cells and simulate flexible manufacturing cells, since it can be reprogrammed not only to identify by colors but also by sizes. Besides, the pieces were built using the 3D printer and the laser cutter in order to use the tools of the laboratories of our institution in the construction of elements for future laboratory equipment which will strengthen the electromechanical program.
