Throughout history it has been proved that tendencies in the manufacturing floor are a reflection of the changes in the customer's demands. Today, markets increasingly require more customized products, with shorter life cycles. In response, manufacturing systems have evolved from mass production techniques, through flexible automation, and to mass customization to produce ‘one-of-a-kind production’ at mass production costs. This paper argues that manufacturing systems of the next generation will have to incorporate more flexibility and intelligence, evolving towards reconfigurable manufacturing systems. In particular, the concept of ‘intelligence’ becomes more relevant because of the need to maintain effective and efficient manufacturing operations with minimum downtime under conditions of uncertainty. This paper presents a comprehensive literature review of the field of reconfigurable and intelligent machines. The relevant research issues for the development and introduction of reconfigurable machines tools are presented.

Challenge Based Learning has been proposed as a teaching-learning technique that helps students develop skills and competencies. A challenge exposes the students to the solution of problems under conditions far out of their comfort zone. A model for the deployment of this technique has been developed at Tecnologico de Monterrey. The model takes the student through a full semester project in an industrial environment. Specific course contents are taught in a modular way during the semester. The model has been labeled i Semester. This article describes some of the challenges of the implementation of the model.

Electric Vehicles with more than one electric motor can offer advantages in saving energy from the batteries. In order to do that, the control strategy plays an important role in distributing the required torque between the electric motors. A dual motor propulsion system with a differential transmission is simulated in this work. A rule based control strategy for this propulsion system is proposed and analyzed. Two parameters related to the output speed of the transmission and the required torque are used to switch the two modes of operation in which the propulsion system can work under acceleration. The effect of these parameters is presented over the driving cycles of NEDC, UDDS, and NYCC, which are followed using a PID controller. The produced energy losses are calculated as well as an indicator of drivability, which is related to the difference between the desired speed and the actual speed obtained. The results show that less energy losses are present when the vehicle is maintained with one electric motor most of the time, switching only when the extended speed granted by the second motor is required. The propulsion system with the proposed control strategy represents a feasible alternative in the spectrum of sustainable transportation architectures with extending range capabilities.
