A novel fluid haptic interface

This paper purposed a novel method for developing a Haptic Interface based on a fluid system. This haptic device uses fluid flow dividers to control velocity relations between its generalized coordinates. Since, there is no power add to the system, the novel fluid haptic interface is intrinsically passive and thus safe to directly interact with human operator. We designed and developed a planar fluid haptic interface prototype. In addition, we reviewed characteristics of valve, cylinder and nonlinearity of air. The simulations of the device also included.
