ABSTRACT:
The present invention relates to a haptic joystick system that is used with a computer system. The system according to the present invention includes the mechanism comprising the first link work and the second link work that respectively conduct 3 degree-of-freedom independently and are serially connected to each other. Therefore the said mechanism conducts 6 degree-of-freedom. The said mechanism is provided at its base plane with sensors and actuators, whereby not being affected by the inertia of the sensors and the actuators. Also, in the system according to the present invention, the first link work conducts 3 degree-of-freedom among the overall 6 degree-of-freedom that are frequently used in its application, and the second link work conducts another 3 degree-of-freedom. Thereby, the system according to the present invention can achieve the enhanced performance related to the energy effectiveness and the controllability.
