In this webinar we introduce the Vanderbilt University Haptic Paddle, a one-degree-of-freedom force-feedback robot used in teaching system dynamics. The haptic paddle was originally developed at Stanford University and has since been adapted by several other institutions. At Vanderbilt University, we have contributed to the evolution of the paddle, particularly in its software platform.

We have transitioned the software of the haptic paddle from its original C architecture to the MATLAB and Simulink environment, enabling students to take on a much greater role in modeling and controlling their paddle. Throughout the course of the laboratory, students learn how to build simple Simulink models; interface them with the paddle, which runs on an Arduino board; and compare experimental data collected in real-time with model predictions. Further, students interact with virtual systems in Simulink and actually “feel” the system’s response. Thanks to the Simulink environment, all of these exercises are done without the challenges often associated with low-level programming and encourage students to engage in inquiry and reflection.

This webinar introduces the haptic paddle and its laboratories, with an in-depth look at each lab.

About the Presenters: 

Jenna L. Gorlewicz is currently in the fourth year of her Ph.D. work in mechanical engineering at Vanderbilt University, and she is a National Science Foundation Graduate Research Fellow. She was the recipient of a MathWorks Education Curriculum Grant for her work in designing and assessing engineering curriculum using haptic paddles in MATLAB and Simulink. Her current research interests are in developing novel devices and methods for engineering education, including haptic touchscreen interfaces to help teach graphical mathematics concepts to blind children. She received her B.S. in mechanical engineering from Southern Illinois University Edwardsville.

Louis B. Kratchman joined the Medical and Electromechanical Design Laboratory at Vanderbilt University in 2009, where he is currently working toward a Ph.D. in mechanical engineering. He was the recipient of a MathWorks Education Curriculum Grant for work in designing and assessing engineering curriculum using haptic paddles in MATLAB and Simulink. His research interests include medical robotics, parallel robots, image-guided surgery, and haptics. Currently he is developing tools and techniques for minimally invasive cochlear implant surgery. He has a B.S. in mechanical engineering and a B.A. in psychology, both from the University of Michigan, Ann Arbor
