Incorporating Motion Capture Technology in Undergraduate Engineering Dynamics

This paper examines the effects of introducing students in an undergraduate dynamics course to motion analysis technology. Motion capture technology is used in a variety of engineering fields ranging from biomechanics research to surgical technologies and computer vision. In typical dynamics courses, little is done to connect the methods and theories being taught to practical applications a student may encounter in an engineering job. As a result, students are often insufficiently motivated in their study of dynamics. The students used the live motion capture technology found in the Human Motion Biomechanics Lab at Cal Poly to analyze the kinematics of a real life application. The motion capture system consisted of near infrared cameras tracking the location of retroreflective markers. The students chose a real life particle or rigid body dynamics application, designed an experiment and created their own dynamics problem which they then solved with the data they acquired. We hoped that allowing students to choose their own topic of study would help increase their motivation levels and allow them to see how dynamics principles apply to their everyday lives. Students’ project ideas ranged from utilizing the human body to create rigid body problems to impulse-momentum problems by colliding objects of different mass. Finally, the students were asked to word their project as a dynamics problem similar to what is found in their textbook and solve it using the acquired data. Additionally, they were asked to reflect on the accuracy of their analytical solution compared to the numerical solutions from the acquired data. We will report on how the students performed on the dynamics task, and provide results of a subjective survey to assess student motivation and learning. Additionally, we will discuss best practices for other instructors who may wish to incorporate similar projects in their own courses.
