Abstract
A haptic simulation method determines a location of a needle assembly within a magneto-rheological fluid. The needle assembly within the magneto-rheological fluid is associated with a desired resistance value. A viscosity control signal representative of the desired resistance value is generated. The viscosity control signal is applied to a viscosity control device to vary a viscosity of the magneto-rheological fluid to achieve the desired resistance value.
