The research consists in the study of cutting workplaces, in order to subsequently develop an ergonomic evaluation of the workers in this area and to obtain results of the ergonomic risks associated with the work. It could be determined that the appropriate method for the ergonomic evaluation was RULA. Once these workplaces had been evaluated in the traditional way, the postural risk evaluation system was developed and programmed. This system works with the Kinect V2 sensor, specifically with the depth, skeleton tracking, and color sensors; the system determines angles and measurement points between each joint of the body, each of them referenced to the value established in the RULA evaluation matrices at certain times.
