The snaptic paddle: a modular haptic device

摘要

The haptic paddle was developed previously as an inexpensive haptic device for educational use, and has been applied to course topics such as dynamic systems and introductory controls. However, it has only a single degree of freedom, limiting it to very simple modeling and simulation exercises. Through modifications to the original haptic paddle design, a "snaptic paddle" has been created that allows two modular one-degree-of-freedom devices to be connected to form a single two-degree-of-freedom device that operates like a traditional joystick. The devices can also be used separately, creating a flexible, economical haptic interface for educational applications. The device successfully provides force feedback interaction, as will be shown in a demonstration at the World Haptics Conference.
