A haptic driving apparatus provides a user with electrovibration of certain strength regardless of a variance of a surrounding environment, and an electronic device has a haptic function. The haptic driving apparatus comprises a haptic electrode driver generating a haptic driving signal to supply the generated haptic driving signal to a haptic electrode through a current monitor and varying the haptic driving signal in accordance with voltages at both ends of the current monitor.

Haptic driving apparatus and electronic device having haptic function

The present disclosure provides a method and device for controlling a haptic interface, which can maintain stability and enhance transparency by restricting force caused by unnecessary energy generated in the sample and hold processes while controlling the haptic interface. The method includes detecting a physical parameter based on driving of the haptic interface; calculating a reaction to be sent from a virtual environment to the haptic interface according to the physical parameter; calculating a bounding parameter satisfying a condition that a haptic system is passive, using the physical parameter and the reaction; adjusting the bounding parameter to be within a preset range; calculating force to be output to the haptic interface according to the adjusted bounding parameter; and applying the calculated force to the haptic interface.

Method and device for controlling haptic interface

The present invention relates to a control method and device for position-based impedance controlled industrial robot, and more particularly, a control method and device for position-based impedance controlled industrial robot able to improve contact stabilization with regard to an environment with a variety of stiffness. According to a control method and device for position-based impedance controlled industrial robot in accordance with the present invention, a robust contact stabilization for a position-based impedance controlled industrial robot contacting and interacting with an uncertain actual environment may be guaranteed.
