[D81] Hapkit: An open-hardware haptic device for online education

Summary form only given. Courses involving a laboratory component are conspicuously missing from the recent upsurge in online courses, limiting student access to hands-on educational experiences. We present a low-cost, open-hardware haptic device, called Hapkit, designed to provide a hands-on laboratory experience in an introductory online haptics course. Hapkit is a one-degree-of-freedom kinesthetic haptic device that allows users to input motions and feel programmed forces. Based on previous haptic paddle designs, Hapkit consists of a motor, magneto-resistive sensor and rotating magnet, laser-cut acrylic structure, friction drive, force-sensitive resistor, and custom Arduino-based controller board. The CAD files, parts list and costs, assembly instructions, and sample software are posted at http://hapkit.stanford.edu so the public can both recreate Hapkit and modify its design. The corresponding online haptics course, piloted in Autumn 2013, will be available as a self-paced course at http://hapticsonline.stanford.edu. In this demonstration, conference attendees will be able to assemble and program Hapkits.
