Engineering education is a difficult concept for student learning because the student must apply scientific disciplines and connect Abstractconceptual for a design solution to solve a problem. The exciting concept in Mechatronic engineering education is concerned with the basic laws concerning physical nature. Students will learn about machine design and controls, but it is hard to understand. This paper aims to design and develop a Series Elastic Actuator (SEA) as a mechanical tool to moti vate student learning in concepts of mass -spring -damping and closed -loop control systems based on the revised 5E model in STEM education. The students’ activities involve hands -on learning mass -spring -damping and the control systems of SEA. This learning approach helps students to have more interactive learning in a classroom. Moreover, it makes students systemically think and understand the relationship between theory and real -world application.

The feedback control system laboratory is required to enhance the knowledge of enrolled students. However, the apparatus provided by educational company usually is high cost, needs a high- performance computer and the professional instructor to conduct the experiment. In this paper, the designing of project -based learning for self -learning embedded control system is proposed. The low -cost experiment kits for microcontroller -based control can be alternately solution instead of using virtual or remotely experiment. In this work, two different types of plant systems: air levitation system and serial elastic actuator are presented. Both are easy to construct and able to implement the controller with any microcontroller. The real-time operation system for embedded system is also introduced which required for industrial control. Based on project -based approach, there are four stages guiding students and teacher to follow up the content and assessment so that the objective of embedded control learning can be achieved within 16 weeks.

In Thailand STEM education, teaching of robotics or automatic control in undergraduate is limited to the theoretical textbook s or computer simulation due to inadequate control plants for classroom demonstrat ion and laboratory experimentation. This crucially prevents students to understand the gap s or limitation s between the theory and the real-world problem. Thus, this research is aimed to design and develop the robotic platform, which is the rotary -type double inverted pendulum, by considering low fabrication cost, easy part maintenance and safety. Also, the platform permits the students to design the Linear Quadratic Regulator (LQR) controller and imp lement it for balancing the robot.
