Abstract

Haptic interfaces or devices are computercontrolled robotic systems that seek to replicate the touch experience of a human user¹. The purpose of this research is to develop a viable variable-stiffness compliant joint for haptic interfaces that eliminate rotation joints or screw mechanisms that induce friction, increase weight and cost, and make devices more complex and prone to failure. The resulting compliant haptic device was designed with both affordability and dependability in mind, and hopes to result in research knowledge leading to realistic touch experiences as users interact with virtual or remote environments. The joint may also be applicable in other common future applications such as robotic arms and legs, rehabilitation robots, and haptic educational tools.
