Abstract
In this paper, a new haptic device “DELTA-4” within a high force feedback capability and operability is proposed. DELTA-4 realizes 3 degrees of freedom of translational motions by a novel redundant parallel link mechanism. These benefits can be obtained by DELTA-4 comparing with conventional parallel mechanisms: wider working area, smaller footprint and easier access to the wide range of working area from operators. In this paper, kinematics and its analysis of DELTA-4 are introduced. In addition, an evaluation experiment of force display is presented.
