Abstract:

The overall thrust of this research was to design a motor/damper system for a proposed six degree of freedom haptic device designed by Burns [2]. First, the thesis addresses the importance of damping in providing stable and "real" touch feedback to the user. Second, the work addresses motor issues regarding advantages/disadvantages to brushed versus brushless motors, different commutation methods, and position feedback sensors. Finally, damper design issues are discussed. These issues include: 1) torque sensor selection and setup, 2) cancellation of noise caused by internal and external loads, and 3) advantages of damper adjustability.
